Grouping database column output with separator
Using Coldfusion MX 7 with SQL Server 2005. I'm outputting the results from SQL Server in a table in which I want to group one of the columns with a separator between the like values, like so:
1 Bobby
1 Thomas
1 Jason
2 Harold
2 George
5 Mark
5 Alex
5 Wes
I can group them fine, but my output normally just puts the separator at the end of the total results like so:
1 Bobby
1 Thomas
1 Jason
2 Harold
2 George
5 Mark
5 Alex
5 Wes
I know this is a simple solution, but I can't wrap my thoughts around it.
Nested <cfoutput....> tags. You did not describe what columns are used for that display so I will just make them up.
<cfoutput query="aQry" group="aNumber">
<cfoutput>
#aNumber# #aName#<br/>
</cfoutput>
</cfoutput>

Pre populate an item with source type="Database Column"
Hello gurus,
How can I pre populate an item with source used "Always, replacing any..." and source type="Database Column"?
I have a form that creates/updates rows in a table and when creating a new row I want to populate some of the fields based on some parameters from the previous page. How can I achieve this?
I tried adding a conditional process when PK is null and populate the expected fields, but in the browser they are not shown with those values, even if I look into the session I can see that they have the values assigned in the process ?!?!?!
Thanks in advance,
FlorinFlorin,
Use the Default Value item attribute. In you case, set the Default Value Type to Static Text with Session State Substitutions and enter your item using the &P1_ITEM_NAME. syntax in the Default value text box.
Thanks,

Interactive Report Download CSV file Issue (output includes separator BR)
Hi,
I have a Interactive Report and displaying the column values (multiple values in same ROW) as mentioned below.
SQL Query
select deptno,
function1(empno) empno
from emp
IR Output
Dept Employee No
10 AAA,BBB,CCC, ... // - Row 1
20 XXX,YYY,ZZZ, ... // - Row 2 Now I want to display each employee in a new Line, so modified the SQL Query
Modified SQL Query
select deptno,
REPLACE(function1(empno),',','<br>') empno
from emp
New IR Output
Dept Employee No
10 AAA
BBB
CCC
... // - Row 1
20 XXX
YYY
ZZZ
... // - Row 2 SO, Interactive Report Out put looks fine and that's the way we want.
But the problem is when I download the Report in CSV or in PDF using the Action Menu -> Download..
I am getting break line B R in the output, and also I have two different output in CSV for two different column. [Logic is same for both the columns.]
CSV output1
Employee No
AAA<br>BBB<br>CCC
XXX<br>YYY<br>ZZZI have other columns also with multiple values...for that column, I am getting the following CSV output
CSV output2
City List
1111<br>
2222<br>
3333<br>So, in CSV for one column, I am getting all the values in same line with the seperator B R (Output1)
for other column, I am getting values in new line with the separator B R. (Output2)
Is there a way to FIX this CSV or PDF output for Interactive Report.
I DON'T WANT THE SEPARATOR BR in CSV and also the values should always be in New Line.
I want to have the following Output in CSV
Employee No
AAA
BBB
CCCThanks,
Deepak

Edited by: Deepak_J on Feb 24, 2010 11:48 AMThanks.. Jari.. for the quick response.
I updated my SQL query with Chr(10) and added the code in Page HTML header.
Now the CSV & PDF output are fine..getting each individual value in seperate line (no BR tag)
BUT in the Interactive Report Output, I am now getting first 2 values in 1 line, then next value in next line, and so on..
IR Output
Employee
AAA BBB
CCCCCCC
DDDDDI have few more issues with CSV & PDF output
1. In PDF is there a way to increase the column width, as for some of the columns, the values are getting truncated.
2. For some of the columns in IR Report, I have user BR tag in Column Heading and this also come in CSV output (column heading with BR tag), is there a way to fix this. In PDF Column headings are fine (no BR tag)
and by the way..what exactly this does.

Select from table in group of columns and generate a sequence number
I have to select data from a table in group of columns and generate a sequence for every group resetting the sequence to start from 1 onwards.
For example:
Data:
Col1 Col2 Col3 Col4
A NA KA 2009-08-13
B NA KA 2009-08-13
C NA KA 2009-08-13
A NA KA 2009-08-13
B NA KA 2009-08-13
A NA KA 2009-08-13
Expected output from Select Statement:
Col1 Col2 Col3 Col4 Seq_No
A NA KA 2009-08-13 1
A NA KA 2009-08-13 2
A NA KA 2009-08-13 3
B NA KA 2009-08-13 1
B NA KA 2009-08-13 2
C NA KA 2009-08-13 1
How can this be possible with a SELECT statement? Is it possible to assign seq numbers for a group of columns and reset it when it changes? In the above example, all columns form the key to generate the seq number
I know it can be done using Stored procedures and that is how I am doing it now by introducing a temporary table.
Can anyone help me in this regard? Please let me know if the question is vague to understand!
Thanks,

and also order by you can just do on the column you need. -
How can I replace column value with a particular value in SQL
Hi All,
Can anyone please tell me how can I format my output with replacing a column value with a specific value which actually depends on the present value of the column
I am executing the following SQL statement
select state,count(id) from <table_name> where composite_dn= <composite_dn_name> group by state;
My Present output is:
State No.Of Instance
1 3
3 28
I want to replace the value in the column state as follows
State No.OfInstances
Completed 3
Faulted 28
I want "1" to be reppaced by "Completed" and "3" to be replaced by "Faulted"
Is is possible with SQL or PL/SQL , if it is then how can I achieve this required result. Please help!!
Thanks in Advance!!
Edited by: Roshni Shankar on Oct 27, 2012 12:38 AMHi Roshni,
I guess this CASE clause can be simulated by a DECODE and also it is very easy to use.
Refer -- http://www.techonthenet.com/oracle/functions/decode.php
select decode(t1.state,t2.state_id,t2.state_name), t1.count_id
from <table_2> t2, (select state,count(id) count_id
from <table_name>
where composite_dn= <composite_dn_name>
group by state) t1
where t1.state = t2.state_id;HTH

Crystal Reports XI - How to pull same column value with different select...
I have a report with many (around 30) sub reports and it is giving serious performance issue. I am currently finding out a strategy to improve the performance. I see that most of the sub reports are taking same parameters from main report except for one parameter which is different for each sub report and hard coded in them and pulling up the same column value from a oracle database with a different select criterion. I am trying to find out a way using either of command/crystal formula/SQL expression which can do the same job for me and give me performance improvement. I tried to take the parameters from the main report in one sub report and mapped them to parameters being transferred to the command and then drag and drop the field for which I need to display the value but due to some reason it is not returning values when I am trying multiple commands...I need some help in selecting a strategy for this issue resolution and some guidance....Any help would be highly appreciated....
My version is 11.5.8.826. First of all I need to make it clear that I have 6 set of sub reports and each set has 5 sub reports. So if I can resolve the issue for one set, I resolve it for all. The sub reports are doing nothing but fetching a column value using a simple SQL SELECT query and appending to the right of a box in main report. The issue is that all these queries embedded into the sub reports are using same SQL except for one parameter in the "where" clause and they are fetching same column value from the database and fortunately all of them are returning same number of results. So at the end these results create a table when run. The only way I can stop using sub reports is by creating a table in the main report and use some object(formula/command/SQL expression or whatever) to fetch that column value using the same filter conditions. But please take a note that I need to use and append the same column value from a database table and use different filter conditions and append them to the right so that at the end they create a table...as long as I get the table in the output with a decent performance , anyone will be least bothered about what I used inside the report.....please ask me as many questions to get more lights on the issue....

Is it possible to create a Webservice in BI which takes XML as an input and gives PDF as output with an additional requirement that Siebel expecting the XSD from BI to send data in the BI requested format. Siebel wants to send the data as xml to BI but not sure of the BI capabilities on giving WSDL embedded with XSD (input is a hierarchical)
Hi All,
I am able to fulfil above requirement. Now I am stuck at below point. Need your help!
Is there any way to UPDATE the XML file attached to a Data Definition (XML Publisher > Data Definition) using a standard package or procedure call or may be an API from backend? I am creating an XML dynamically and I want to attach it to its Data Definition programmatically using SQL.
Please let me know if there is any oracle functionality to do this.
If not, please let me know the standard directories on application/database server where the XML files attached to Data Definitions are stored.
For eg, /$APPL_TOP/ar/1.0/sql or something.

How do I null out an item based on a database column before display?
I am using Apex 3.2
I have an item that is based on database column. My customer wants me to "blank out" the item before it is displayed so the user will have to enter a new value in place of the one that is in the database.
I have tried using a "before region" calculation to set the item to NULL. I can see the value getting set in the debug after the row fetch has occurred, but when the item is displayed, it contains the value from the database, not my calculated valuie.
I also tried using an unsourced text field and then doing an after submit calculation to set the value of the database column item from there, but no luck that way either.
Also tried clearing the item cache, but I think that happens way too early.
There must be a simple way to do this..
Any suggestion?No problem user486652 (name?),
Yes, the $s function is one of ApEx's built-in's - see the ApEx documentation under API Reference, Javascript API's, and you'll find a wealth of built-in functions that do all sorts of things. For Javascript in general, take a look at www.w3schools.com for some really good tutorial and reference material - I use it constantly.
Ok, so you want to set the browser field to empty after the page loads. Since this is a page event, it isn't something that will fire for a form field element so you don't want the code there. In ApEx 3.2, edit the attributes for the page, and you'll see a setting called "HTML Body Attribute". You'll see a helpful bullet note below the setting saying this is the place to add onload events. The proper syntax will be:
onload="$s('P2_REMEDY_TICKET', '');"Once ApEx puts everything together and the page renders, this code will tell the browser to run that $s function after the page loads.
But be aware - if you take a look at the help for that setting, you'll see that it mentions that this will only work if your page template includes the #ONLOAD# substitution string. Not sure if all ApEx-supplied page templates already have #ONLOAD#, but every one I've used does. If your code still doesn't work, check your page tempate. In the Definition region, under Header, you should see a body tag with something like:
<body #ONLOAD#>...
...If that's there, your page template supports the HTML Body Attribute. If your body tag doesn't have an #ONLOAD#, add it.
Hope this helps,
John

Column chart with null data items
I have a Column Chart with an ArrayCollection data provider.
The data will sometimes have missing items in some "rows'. For
example, it might look like this where the second object has no
"Male" property:
public var myData:ArrayCollection = new ArrayCollection([
{School: "Priorford", All: 95, Male: 92, Female: 98},
{School: "Giffnock", All: 87, Female: 89},
{School: "Hastings", All: 80, Male: 78, Female: 82}
Sometimes I get the following error:
TypeError: Error #1009: Cannot access a property or method of
a null object
reference.
at mx.charts.chartClasses::NumericAxis/mapCache()
I'm assuming the error is because of missing data items, but
I'm not 100% sure. Some data sets with missing items will display
with no error. I can't see a pattern to those that don't.
-- I can't produce the error when using a "static" data
source set in the Flex app itself (such as the example above).
These always display correctly, even with missing items.
-- In the problem case, the source data comes from a MySQL
database through a PHP script that is called with a Flex
httpService. The returned data is parsed in Flex, and put into the
ArrayCollection. I was suspecting that the returned data was flawed
in some way, but the same ArrayCollection displays correctly in a
DataGrid. The problem is only with the Chart.
-- I can work round the problem by adding the missing
properties and setting them to an empty value. But I don't think I
should have to do this.
Has anyone seen this problem, or know of any obvious thing I
might be doing wrong.Thanks Arthur.
Your first suggestion is effectively what I'm doing as a
workaround. But it is a bit of a pain to have to account for this
each time when displaying a chart. It's a particular problem when
you don't know in advance what "categories" might be returned by
the data and that have to be charted.
My biggest concern is that this looks like a bug, and the
fact that it seems to occur intermittently is a bit worrying. (I
also know that eight out of ten reported "bugs" are user error,
which is why I was wondering if anyone else had experienced this.)
About your second suggestion, I think the interpolateValues
property only applies to lineSeries. -
How to display G/L Account code with separation symbol
Hi, there
I got a problem that I want to show formated account code in one column in grid, which formated with separation symbol, and i'd like to binding this column to one user defined field in UDT, user can input Acount code in this column. who knows if there is a simple way to show the formated Account code. I am using SBO 2004 and VB .Net.
I did not find any function about it in SBO 2004 SDK, the "FormatCode" property in ChartOfAcctounts object only show Account code with out separator, so am I need find out the segment and separator information and format using code?
Thanks for any help.
KathyHi Kathy
Not sure what you asking.
The one part you asking "how can I show the link button in the Account code column". The answer to this is if you are using the xml form made by the screen painter you must open the xml file outside of screen painter and make that column of type 116 instead of 16. Obviously you still need to do the usual like bind the column and set LinkedObject = APbouiCOM.BoLinkedObject.lf_GLAccounts
Then to the second part of your question
A linked button for a gl account with dashes which are "-" should pull the chart of accounts window open. The format code with the dashes is CORRECT! You must make sure there is no unwanted spaces or any funny characters. Also i did the linked button in Screen Painter. Make your arrow, link it to a edit box.Then set linkedObject value to 1.
Just for testing purposes make a edit text with the linked button linked to it. Type a gl account manualy in the box with dashes and then press the orange arrow. You'll see that it works with the dashes.
Hope this helps -
Formatted HTML output with Spry regions - is it possible?
I have recently begun using the XML export extension in
conjunction with an Access database to output dynamic data into a
page with a Spry master/detail setup. So far, my simple example is
going great, but I've run into a snag that I need some help with.
To explain what I'm doing - it's a simple article page with
the list of articles on the left with the title and date and the
article title and full contents on the right hand side. So far it's
all working very well, updating in real time when I click an
article title on the left. The problem is the output with this one
field which stores not only text, but also HTML formatting that is
generated by a wysiwyg editor used on the article creation side of
this little app. This HTML formatted content is the article body
and is stored in a field named the same - "body". With traditional
ASP, the HTML formatting displays as expected and all is well, but
with Spry, it doesn't output formatted HTML, but instead shows the
content and HTML code together as text. How can I get this one
field ("body") to be output so all the HTML formatting is shown?
This is my simple page example. Click through and you'll see
what I mean.
http://www.shoestodyefor.com/ajax.asp
Here's the section of code in question regarding the output
on that right hand panel where the body is displayed for each
article:
<div spry:detailregion="ds1">
{title}<br />
{entryDate}<br />
<br />
{body}
/div>
Is it possible to have that {body} section shown so the
dynamically created HTML code from the wysiwyg editor is displayed
correctly?Steve Skinner wrote:

The version of Spry that ships with Dreamweaver CS3 (Spry
1.4) doesn't
support the type of output created by the XML Export
extension.
This issue has been corrected in Spry 1.5, but no plans have
been made
public for integrating Spry 1.5 into Dreamweaver CS3. You
would need to
download Spry 1.5 from
http://labs.adobe.com/technologies/spry/.
Details
of how to hand-code the fix for output from XML Export are

Multiple row column-sharing with GridBadLayout does not work as expected
I was trying to figure out why I could not initially accomplish the following with a GridBagLayout:
Row0: 0000011111
Row1: 1111122222
Row2: 2222233333The above is supposed to be 3 JLabels on three different rows:
The 1st row has a single JLabel starting in column 0 with a width of 2, extending it to column 1.
The 2nd row has a single JLabel starting in column 1 with a width of 2, extending it to column 2.
The 3rd row has a single JLabel starting in column 2 with a width of 2, extending it to column 3.
The entire grid is 4 columns and 3 rows total.
Below I have two examples where I attempted the above. Only the 2nd example produces the desired effect. The 1st code example ends up putting both the Row 0 and Row 1 JLabel in the same column. This was surprising because I thought the GridBagLayout would give each column contained by a control enough weight to actually make those columns exist.
Here is what my first code example below produces:
Row0: 0000011111
Row1: 1111122222
Row2: 2222233333The first two JLabels, 0000011111 and 1111122222, appear in the same column, and the 3rd JLabel appears in the seemingly 2nd column. This was confusing to me which is the point of this whole post.
In order to gain the desired effect, I had to place 4 blank dummy empty JLabel components in a non-visible Row 0 of the grid. I did this for all 4 columns of that invisible row 0. The row is non-visible because the JLabel have no text or output. After adding this non-visible Row 0, all of the original mentioned Rows 0 through 2 become Rows 1 through 2 respectively.
For example:
Row0: iiiiiIIIIIiiiiiIIIII
Row1: 0000011111
Row2: 1111122222
Row3: 2222233333The above shows an inserted Row 0 with invisible labels that are not seen, but they seem to give weight to each column, allowing each to exist. Without doing this, as mentioned, the first code example (shown below) fails. The second example (also below) works, so it appears that putting the invisible controls into the first row, one in each column, somehow gives enough weight to each column to "establish" the column more so than otherwise.
The big question I have is why didn't the first example work?
I mean, in that example, I'm giving each JLabel equal weight, and each one takes up a width of 2 columns, so why doesn't the JLabel in the second row end up in column 1? Instead, both the original row 0 and row 1 JLabels appear in what looks like column 0, the same column. Does anyone know why this happened?
The invisible control solution is fine but I'm just curious why it wasn't as intuitive as it should have been. The only thing I can come up with is that the weight of the 1st and 2nd JLabel (row 0 and 1) got combined in some fashion which combined them into column 1 which end up looking like column 0 since 0 somehow looses all weight. (???)

}I think I figured out the general reason for the problem based on a quick trace through of the GridBadLayout code in a simple example, and I wanted to share my findings in case they may be useful to anyone else. I felt there were some concepts gleaned from the source code that don't appear reinforced with documentation or, more importantly, in tutorials or books I checked. That's why I wanted to share my findings with this simple yet perplexing example.
This example is very much like the one in my original post except it is more simple and only uses two JLabels.
I created a grid with the following settings:
JLabel1,gridx=0,gridy=0,gridwidth=2,weightx=1.0
JLabel2,gridx=1,gridy=1,gridwidth=2,weightx=1.0Using the character '1' for JLabel1, and the character '2' for JLabel2, and 'x' for an "empty" grid cell, the above gives me the following simple conceptual layout:
11x
x22But the 'x' cell columns don't receive any weight, so things actually appear as follows:
11
22Internally, GridBagLayout (GBL), is really producing the following:
11x
x22But since the 'x' locations take no weight, they therefore get no size, so both JLabels appear as though they are in the first and only column.
From what I can see, it doesn't really matter what I do, I'll never be able to produce the following effect with just two JLabels:
11x
x22I cannot do the above with just two JLabel components and a GridBagLayout. The reason is that the GridBagLayout, while it does define a "grid" of rows and columns, the grid is not a grid that actually relates to what is displayed. It's really a grid that defines what I'll refer to as "weight collisions" or "weight pools." If two components share, say, a grid column, their weights will combine with respect to that column. But the total size of the grid doesn't play a role in enforcing that some sort of grid display is maintained. The grid can possibly do that, but it would probably be safer to view that result as a side-effect produced by using the "weight pools" created by the grid itself.
In the above simple example, JLabel1 ends up giving gridx 1 (0 being first) its full weight of 1.0. The gridx 0 column receive zero weight from JLabel1. What happens is the code in GridBagLayout sees that there are no presently assigned weights to column 0 and it simply assigns all remaining unassigned weight of JLabel1 to JLabel1's last, right-most in this case, gridx column. This means that gridx 1 gets the full 1.0.
By contrast, though, when processing JLabel2, the GridBagLayout sees the previously assigned 1.0 to gridx 1 (JLabel1's right-most grid column) and it ends up assigning all of JLabel2's weight to that same grid location, gridx 1. In this case, even though JLabel2 supposedly spans through to gridx 2, the actual gridx 2 column gets 0 weight from JLabel2 and therefore gets no width.
The result is that both JLabel1 and JLabel2 give 100% of their weight to gridx column 1 (what I called above a "weight pool" rather than a grid location), and both gridx 0 and gridx 2 receive 0 weight and I'm guessing appear without any size. What's odd about this is that even though JLabel1 starts at gridx=0, it really doesn't draw itself anywhere but starting at gridx=1. Likewise, even though JLabel2 draws itself supposedly from gridx=1 through to gridx=2, it doesn't really go into gridx=2 because gridx=2 doesn't get any width.
In fact, given the code in GridBagLayout, it doesn't matter how much weight I give to either JLabel, all 100% of the weight will end up in gridx 1, the "center" grid location. The only way to get columnar distribution is to create other components to force the GridBagLayout to see individual columns which match the "grid." When I do this, the columns allow me to create the JLabels in a fashion where they intent/stagger, where a JLabel can start at a "column" location that is in the middle of another JLabel.
Given this, I've come to the conclusion that it's not worthwhile to look at the GBL "grid" as a grid that propagates grid-like visual locations. It's more like the grid exists during the computation of weights which end up determining the true columns and rows that will visually exist, which may well not be anything like the grid locations one might visualize when looking at the constraints used.
I think it's unfortunate that many examples and tutorials don't reinforce this concept with simple examples that help one grasp this easily. Most examples I see actually can fool a user into thinking a grid is a true grid in that positions represent visual locations, or that a control spanning into a grid column means that weight will be (at least) partially distributed there.
You very often won't see the problem I'm describing above when you have dialogbox-like alignment of components which most tutorials and examples utilize. For example, if I take the same example as above, but intent JLabel so that it's gridx is 2, not 1, then both JLabels will not be sharing a single grid column so their weights won't collide. In such a case, one might be misled into thinking that a GridBagLayout's grid is truly providing row/col locations when it's not really doing that. Instead, in this latter case, one is really gaining that effect because certain unintuitive weight collisions. which would produce unexpected results, are being avoided.
I thought weightx values would give a weight equally to all gridx columns that a component spans but that doesn't seem to be the case here. In fact, it's not even a components first column in my simple example above. GBL causes JLabel1 to given all its weight to gridx=1 (and nothing to gridx=0) while GBL causes JLabel2 to give all its weight to gridx=1 (and nothing to gridx=2). In one case, JLabel1, all weight goes to its right-most spanned-to column, while with JLabel2, it goes to JLabel2's entire first gridx location.
I guess this is what makes GridBagLayout (GBL) unintuitive. But I don't think it's so much unintuitive as it is probably not well documented. When you look at the source code, it explains stuff which should be in the docs. In fact, not one single book I saw gave any help in solving this problem. I'm guessing this is largely because folks use GBL through trial and error until they get what they want, and perhaps they don't often need to indent halfway as I'm trying to do with GBL in the above example. If a lot of components are aligned, the results are not as unexpected. I'd say, though, that even in those not-so-confusing cases, GBL can troublesome without knowing its grid is all about a grid of weight pools which may or may not produce a visual grid depending on all components' constraint settings. -
Checking whether data exists in a BLOB type database column in Forms 6i
I am developing an application regarding inventory of a plant's spare parts. I am storing photo (.bmp) of spares in the database in a column of BLOB type. Once user punches spare's code, form displays spares data on screen using EXECUTE_QUERY. At this stage I want to check whether picture (.bmp) data was found in BLOB type database column or not. I want to take action accordingly. How to check this. If it would be a numeric column, I would have checked NULL but NULL does not work with BLOB type coloumns.
Pl. help.
Thanks in anticipation.Did you look in the database documentation? The DBMS_LOB package has the method you need: getlength().
This was more of a database question than a Forms question, so you'd probably have more luck with these types of questions on one of the other forums, like the database or SQL forums.

Encryptind and decrypting database column in oracle 10g
hi guys...
i am sai sandeep,i got a doubt how to encrypt a database column in oracle 10g..?
i am using a table " emp_uid " ,and strtucture as follows,
create table emp_uid(user_id varchar2(20),pwd varchar2(20));
i need to encrypt a pwd column in the emp_uid.
how to do it..?
thanking u advance.....Ok, here's a basic example...
SQL> create table myusers (username varchar2(30), password varchar2(40));
Table created.
SQL> create or replace procedure add_user(username in varchar2
2 ,password in varchar2) is
3 begin
4 insert into myusers (username, password)
5 values (add_user.username
6 ,dbms_crypto.hash(utl_raw.cast_to_raw(add_user.username||'!'||add_user.password)
7 ,dbms_crypto.hash_sh1)
8 );
9 commit;
10 end;
11 /
Procedure created.
SQL> exec add_user('Fred','Fr3ddy')

2 ,password in varchar2) is
3 v_hash varchar2(40);
4 v_username varchar2(30);
5 begin
6 v_hash := dbms_crypto.hash(utl_raw.cast_to_raw(loginuser.username||'!'||loginuser.password), dbms_crypto.hash_sh1);
7 select username
8 into v_username
9 from myusers
10 where username = loginuser.username
11 and password = v_hash;
12 dbms_output.put_line('User: '||v_username||' logged in.');
13 exception
14 when no_data_found then
15 dbms_output.put_line('Username/Password is not valid!');
16 end;
17 /
Procedure created.
SQL> exec loginuser('Fred','Freddy');
Username/Password is not valid!
PL/SQL procedure successfully completed.
SQL> exec loginuser('Fred','Fr3ddy');
User: Fred logged in.
PL/SQL procedure successfully completed.
Ideally you would do the hashing of the password inside the client side application so only the Hashed value goes over the network, but the above demonstrates the principle of using hashes to store passwords. Because it's a one way algorithm, only a brute force method can be used to try and determine the original password. There is no way to directly un-hash the value. To check for a valid login, we don't retrieve the password and try to unhash it to compare against what the user has supplied, we actually take what the user has supplied and hash that in the same way and then compare the hashes.
The point of including the username or some other data in the hashing process means that if two users have the same password, they will still have different hash values, so it won't be apparent they are the same passwords. In my example, the point of putting another character between the concatenation of username and password is in case the username and password together would give the same result e.g.
If we had one user "Fred" with password "Fr3ddy" then just concatenating the strings would give "FredFr3ddy".
If we had another user "FredF" and he happened to choose a password "r3ddy" then just concatenating those would also give "FredFr3ddy"
by introducing a known breaking character they would be different e.g. "Fred!Fr3ddy" and "FredF!r3ddy" and hence give different hash values.
That's the basics of how passwords are stored for security.
It would take a lot of processing power and brute force methods just to determine a single password for a single user when using hashing methods of security.
With encryption, a brute force method could be used to find the decryption key, and once found that could be used to decrypt ALL the encyrpted data, hence it is less secure, especially when some clever person will no doubt have written the key down somewhere so they don't forget it. With hashing there's no key to write down.
