Want to practice SQL queries, do I need to download SQL editor

Hi All,
I have a doubt..
I want to practice SQL queries. for this, do I need to download SQL editor and Intall or If I download any Oracle version, does it will have SQL editor? please anyone answer my question.

I'm not sure how is it related to Peoplesoft, but if you installed an Oracle client on your client machine, then you have SQL*Plus or SQL Developer.

Need help in SQL Queries using GUI controls or variables

Hello, all
I have a big problem (I have already had with Visual Basic a few mounths ago) with Java while writing my SQL Queries.
I would like to know how I must do to use variable data or GUI control data in my SQL Query to select only some records.
Here, my first Query that works without any problem (no WHERE clause !!!) :
Statement requeteBedes = connectBedes.createStatement();
ResultSet resultatSeries = requeteBedes.executeQuery("SELECT * FROM Series");
initComboBoxSeries(resultatSeries);the method "initComboBoxSeries" fills a JComboBox with all the names of the series in my database.
Here comes my problem.I would like to use the value of the selected "series" in the JComboBox to search in another table of the same Database. I made another statement but it returns a Null ResultSet :
ResultSet resultatSearchAlbumsFromSeries = requeteBedes.executeQuery("SELECT * FROM bandes_dess WHERE ser_nom = '" + strComboBoxSeriesSelected + "' "); The variable strComboBoxSeriesSelected contains the value of the selected line in the combobox with all the series, filled after the first query that is here above and that works very well.
Could some one help me and tell me how I must use variables or GUI controls values in my SQL Queries or tell me if there is a place where I could find an explanation of that kind of problems (like more "advanced SQL Queries", as the ones currently used in all the Learning Java 2 books)
Thank you all for your help.
Christian.

executeQuery() will never return null. At least that's what the spec says. You are probably catching an exception (probably a syntax error caused by a single quote in strComboBoxSeriesSelected) and ignoring it. Or do you mean the ResultSet contains no rows?
Anyway, to use parameterized queries, take a look at PreparedStatements. Your code should look like this using PreparedStatement:Statement requeteBedes = connectBedes.prepareStatement("SELECT * FROM bandes_dess WHERE ser_nom = ?");
requeteBedes.setString(1, strComboBoxSeriesSelected);
ResultSet resultatSeries = requeteBedes.executeQuery();Alin.

hi all,
we have a procedure for search consumers, which using sql queries like:
SELECT TRIM (NAME) AS NAME, TRIM (accno) AS accno,
TRIM (connaddress) AS connaddress,
TRIM (CATEGORY) AS CATEGORY, TRIM (landmark) AS landmark,
SUBSTR (accno, 1, 3) AS subdivisionname
FROM consumermaster
WHERE LOWER (accno) LIKE
LOWER ('%' || NVL (caccno, '#noval#') || '%')
OR LOWER (NAME) LIKE LOWER ('%' || NVL (cname, '#noval#') || '%')

it's ok for small tables but now data increase .......
searching method is very slow
now i want to tune this query for better performance
please sugg me best method
Thanks in advance

The link given by Asif should get you on the right track for tuning this query.
I just formatted your SQL:

Also the guidelines in the link provided are the best starting point.

Help needed for SQL query

hello ,
I am a beginner in terms of writing sql queries. I hope some body can help me out.
I have two tables
mysql> desc user_group_t;
---------------------------------------------------+
| Field | Type | Null | Key | Default | Extra |
---------------------------------------------------+
| userAccountId | char(8) | | PRI | | |
| groupId | char(8) | | PRI | | |
---------------------------------------------------+
2 rows in set (0.00 sec)
mysql> desc group_t;
---------------------------------------------------+
| Field | Type | Null | Key | Default | Extra |
---------------------------------------------------+
| id | char(8) | | PRI | | |
| name | char(50) | YES | | NULL | |
| email | char(100) | YES | | NULL | |
| description | char(254) | YES | | NULL | |
| parentId | char(8) | YES | | NULL | |
| creatorId | char(8) | YES | | NULL | |
| createDate | char(20) | YES | | NULL | |
| updateDate | char(20) | YES | | NULL | |
| updatorId | char(8) | YES | | NULL | |
---------------------------------------------------+
9 rows in set (0.00 sec)
what I want is list of all groups with id,name and #of members(which is the # of rows in the user_group_t for any given id). Importantly I need the groups with 0 members also to be listed. In short my output should contain exactly the same number of rows as in group_t table with an additional column indicating # of members for that group.
Any help would be greatly appreciated.
Thanks in Advance.
-Vasanth

Thanks Donald,
Actually I figured it out, with the following query:
select id,name,sum(if(groupid is not null,1,0)) as members from group_t left join user_group_t on id=groupid group by id;
I tried your solution, but mysql says there is an error at '+' . Anyway I modified your solution to the one below and it worked.
select a.id, a.name, count(b.groupid) from group_t a left join user_group_t b on a.id=b.groupid group by a.id, a.name;
I tried that before but then I used Count(*) instead of count on groupid. Your solution is elagant and I will go with yours.
Thanks again.

Developing portlets for dummies (sql queries)

Hello, I've been trying to build a dynamic menu. First I went with just plain old plsql: i created a function in the portal schema that returns an unordered, nested list of the pages in my pagegroup and called that function in a regular pl/sql item on my portal page. I did this by querying the wwpob_page$ table and that went just great in my test&development setup (of which I am the admin of course :))
Then I realized that since I'm not an administrator of the server hosting our portal and I only have very limited privileges (I am only a page group administrator) I will probably not be allowed to utilize this function nor will they agree to install it in the portal schema, and I decided I should build a portlet that does the same thing (so it can be registered and so on, and so it can use the synonyms and tools that are available to registered providers). There already is such a portlet (and provider) registered for use in the target portal, but I don't like it because i uses tables and hard-coded styles so I will cook my own, better version. :)
So I downloaded an example portlet and am getting the hang of it, but now I just can't for the life of me figure out how to enable any sql-queries. I have run the provsyns-.sql script, logged in as test_provider/portal and installed my portlet-package as test_provider user. I can see the available pl/sql packages in Toad, but there are no tables or views for me to to see. That means I can't query the portal tables that I need to.
edit: ok, stupid user error; I suck at using Toad, so I was looking at the wrong schema altogether :D So now i see the public views and packages, so forget that bit of the question.
But still, I cannot see even wwsbr_all_folders -view, much less the wwpob_page$ -table. I cannot see any way to find the pages that are in my page group. Somehow it must be doable, right?
Have I done something wrong, missed a step in enabling my test-provider / schema perhaps? I don't really know what I'm doing, but I followed instructions here: http://home.c2i.net/toreingolf/oracle/portal/my_first_plsql_portlet.htm (excellent instructions, thanks!)
So should my portlet be able to access those tables or not? How the heck has the third partly portlet maker done it?
i'm on OracleAS Portal 10g Release 2 (10.1.4)

i see your perspective now. and let me give a perspective to my first reply too.
what i proposed to you was the answer of what i quoted in the message. that is, why didn't you see those views in the new schema you created! and it is still ok but it is done in the portal schema for which you should have privielges too and i assumed you had. my mistake!
now, i can relate your privacy concerns with your earlier message:

- by downloading an example portlet, you probably mean you created a new schema. because provsyns work on a schema.
- if you are not the administrator of the portal, and may not be able to access some portions of the portal, it means that you do not use the portal user (the user which serves as the owner of the portal schema).
- now, your plan to create a new schema and give those privielges would still not work. because, by creating a new schema you cannot sneak in to the oriignal portal schema if you do not have privileges to do it. obvious, right? otherwise, it would be a vulnerability of the software that you can see what you are not allowed to see by creating a new schema.
- however, there is a bright side here. the views give records based on your privileges.
- so if your administrators have generated them already or if they generate on the original portal schema, then you may see the pages and items that you have privileges to see and no more.
so now, you may ask the administrators if they have already done it, and if not, then if they would be willing to do it.
hope that helps!

Ruby code for sql queries

Hello everybody,
First off, let me apologize if my inquiry does not belong on this forum. I am confident however, that someone here has had experience with this since Oracle and ruby on rails/ruby are used frequently. My fingers are crossed, here's is my problem:
I am currently working on a database system that utilizes ruby on rails
with a oracle database. Here's the situation:
the ruby on rails web application is up and running;
my oracle database is full of tables that are populated with data;
there is a successful connection between rails and my oracle database;
however, what isn't finished is I currently have data mining queries in
sql (eg. find minimum time someone has been employed = "Select
min(time) from table...etc") and what I need to do is write one ruby
program for each of my sql queries so that the ruby program:
1) connects to the oracle database each time the query is called
2) runs the sql query on the oracle database
3) takes the results from the query and returns them in an array or
something of that nature (so that I can use the results in an html file
on the ruby on rails web application).
Again, I apologize if this question does not belong on this forum. If someone however has experience with this could you please give me example code of what this would look like (using different sql queries). Thank you

I apologize if this question does not belong on this forum. OTN does have a forum dedicated to Ruby/Ruby On Rails. I admit it doesn't seem to get much traffic. I think that's because most people working with Ruby tend to go for F/OSS products.
Cheers, APC

SQL queries parser.

Hello,
I have quite strange question related to my research.
Probabley within Oracle DB there is some dynamic library which is parsing SQL queries,
for example.
SELECT * FROM schema.table which is able to extract informations from SQL listed above that we want to display all columns from selected table.
When this construction is valid ( SQL standard ) the next step is verification the object existence in DB. It means
that there are two separated actions which are analyzing queries.
I need only first part of that process, which will give me informations about all object used in SQL query
is it possible to accomodate that internal parser witin stand alone middleware like Weblogic Event Server ?
I can do it with regular expression patters, but it's not going to be fast and effective for subqueries and all advanced
constructions for DHW like MODEL, etc.
Thank You,
R.

Multiple SQL Queries in SAP BPC 5.1 EVMODIFY

Hi All,
We have multiple SQL Queries in Outlooksoft 4.2 which extracts data from Oracle source system with different set of selections and conditions and parameters. We were able to use multiple SQL Queries in Outlooksoft 4.2 using Transform Data Flow Task and paste parameters using evModify dynamic script task, where ever extract to source system is needed.
According to SAP BPC 5.1, all these multiple SQL Queries and extracts by passing parameters will be coded in EVMODIFY dynamic script editor.But, EVMODIFY dynamic script editor is not working with the sets of multiple SQL Queris.It's able to recognize and execute the first SQL Query, but not able to execute from the second SQL Query.
Does any body, did multiple extracts using SQL Queries to the source system by passing parameters using SAP BPC 5.1 data manager and SSIS Packages, please let me know, how you did achieve the above functionality.
Regards,
Sreekanth.

Hi Sorin,
Thanks for your update, I tried declaring the variable between %%....GLOBAL(%GTIMEID%,%SELECTION%) and the package runs now but the problem is that the package is executed using the default date value for the variable GTIMEID declared in the DTSX package and its not taken the date that I'm trying to pass from BPC. As showed below, please if you could take a look to the ModifyScript and see the last line for the global variable and line 13 PROMTP(SELECTINPUT,%SELECTION%,,,%TIME_DIM%) where I am selecting the TIMEID:

How to use database control to execute sql queries which change at run time

Hi all,
I need to execute sql queries using database controls , where the sql changes
at run time
based on some condition. For eg. based on the condition , I can add some where
condition.
Eg. sql = select id,name from emp where id = ?.
based on some condition , I can add the following condition .
and location = ?.
Have anybody had this kind of situation.
thanks,
sathish

From the perspective of the database control, you've got two options:
1) use the sql: keyword to do parameter substitution. Your observation
about {foo} style sbustitution is correct -- this is like using a
PreparedStatement. To do substitution into the rest of the SQL
statement, you can use the {sql: foo} substitution syntax which was
undocumented in GA but is documented in SP2. Then, you can build up
the filter clause String yourself in a JPF / JWS / etc and pass it into
the DB control.
For example:
* @jc:sql statement="select * from product {sql: filter}"
public Product[] getProducts(String filter) throws SQLException;
This will substitute the String filter directly into the statement that
is executed. The filter string could be null, "", "WHERE ID=12345", etc.
2) you can use the DatabaseFilter object to build up a set of custom
sorts and filters and pass that object into the DB control method.
There have been other posts here about doing this, look for the subject
"DatabaseFilter example".
Hope that helps...

Hi Maruthi,
The parameter substituion , I guess is used like setting the values for
prepared
statements.
What I'm trying to do , is change the sql at run time based on some condition.
For example ,
consider the following query :
select col1,col2 from table t where t.col3 > 1
At run time , based on some condition , I need to add one more and condition.
i.e. select col1,col2 from table t where t.col3 > 1 and t.col4 < 10.
This MAY not address your issue but if you are trying to add "optional" parameters
you may try including ALL the possible parameters in the SQL but send in null
for those params that you don't want to filter on in any particular case. Then,
if you word your query
as follows:
select col1, col2 from table t where t.col3 > 1 and (t.col4 = {col4param} or
{col4param} is null) and (t.col5 = {col5param} or {col5param} is null) ...
you will get "dynamic" filters. In other words, col4 and col5 will only be
filtered if you send in non-null parameters for those arguments.
I have not tried this in a WL Workshop database control but I've used
this strategy dozens of times in stored procedures or jdbc prepared statements.
Good luck,
Dan

Problem occured when create a tree table for master-detail view objects using SQL queries?

I am programming a tree table for master-detail view objects using SQL queries and these 2 view objects are not simple singel tables queries, and 2 complex SQL are prepared for master and view objects. see below:

3. I create a view link to create master-detail relationship for these 2 view objects.
masterview.SourceBlock (1)->detailview.SourceBlock (*).
4. I create a tree table using these 2 view objects with master-detail relationship.
When I set default value for variable bindings of these 2 view objects and the matching records exist, tree table can work well. I can expand the master row to display detail row in UI.
But I need to pass in dymamic parameter value for variable bindings of these 2 view objects, tree table cannnot work again. when I expand the master row and no detail row are displayed in UI.
I am sure that I pass in correct parameter value for master/detail view objects and matching records exist.
Managed Bean:
        DCIteratorBinding dc = (DCIteratorBinding)evaluteEL("#{bindings.MasterView1Iterator}");
        ViewObject vo = dc.getViewObject();
        System.out.println("Before MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        System.out.println("Before MasterView1Iterator ShiftModeCode="+ vo.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo.executeQuery();
        System.out.println("MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        DCIteratorBinding dc1 = (DCIteratorBinding)evaluteEL("#{bindings.DetailView1Iterator}");
        ViewObject vo1 = dc1.getViewObject();
        System.out.println("Before DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
        System.out.println("Before DetailView1Iterator ShiftModeCode="+ vo1.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo1.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo1.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo1.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo1.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo1.executeQuery();
        System.out.println("after DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
5. What's wrong in my implementation? I don't have no problem to implement such a tree table if using simple master-detail tables view object, but now I have to use such 2 view objects using complex SQL for my requirement and variable bindings are necessary for detail view object although I also think a bit strange by myself.

Hi Frank,
Thank you and it can work.
public void setLowHighSalaryRangeForDetailEmployeesAccessorViewObject(Number lowSalary,
                                                                          Number highSalary) {
        Row r = getCurrentRow();
        if (r != null) {
            RowSet rs = (RowSet)r.getAttribute("EmpView");
            if (rs != null) {
                ViewObject accessorVO = rs.getViewObject();
                accessorVO.setNamedWhereClauseParam("LowSalary", lowSalary);
                accessorVO.setNamedWhereClauseParam("HighSalary", highSalary);
            executeQuery();
but I have a quesiton in this way. in code snippet, it is first getting current row of current master VO to determine if update variables value of detail VO. in my case, current row is possibly null after executeQuery() of master VO and I have to change current row manually like below.
any idea?
            DCIteratorBinding dc = (DCIteratorBinding)ADFUtil.evaluateEL("#{bindings.SSForecastSourceBlockView1Iterator}");
            ViewObject vo = dc.getViewObject();
            vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
            vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
            vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
            vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
            vo.executeQuery();
            vo.setCurrentRowAtRangeIndex(0);
            ((SSForecastSourceBlockViewImpl)vo).synchornizeAccessorVOVariableValues();

Monitoring Oracle SQL queries in VBA

I currently use VBA with Excel to generate reports based on data within an Oracle 9 database. The amount of data is very large and the reports can take a long time to process. I have added status bar progress indicators for the majority of the report processing tasks to inform the user of what is going on.
The problem is that I need to be able to monitor the progress of the main SQL queries since they take upwards of a few minutes to run each (mainly because I need to rank and order data). I currently use code similar to that shown below to query the database from VBA.
Sub simpleVersion()
Dim username As String
Dim password As String
Dim sid As String
Dim objSession As Object
Dim objdatabase As Object
Dim OraDynaset As Object
Dim strSQL As String
username = "user"
password = "pass"
sid = "database"
' connect to database
Set objSession = CreateObject("OracleInProcServer.XOraSession")
Set objdatabase = objSession.OpenDatabase(sid, username & "/" & password, 0&)
strSQL = "select latitude, longitude, otherdata from scatter where otherdata > 50 order by latitude, longitude"
' This command takes a long time to execute when doing ranks/order bys
Set OraDynaset = objdatabase.DBCreateDynaset(strSQL, 0&)
Do While OraDynaset.EOF = False
'Process the data and put on a spreadsheet
'Status bar messages can be used here without problems
OraDynaset.MoveNext
Loop
Set OraDynaset = Nothing
Set objSession = Nothing
objdatabase.Close
Set objdatabase = Nothing
End Sub
When the DBCreateDynaset command is executed VBA waits until the dynaset data is retrieved from oracle. I would like to be able to do something similar to the pseudo code below.
Execute SQL to create dynaset
Do while still obtaining dynaset
Check v$session_longops - Indicate time taken / remaining on status bar
Loop
I have found that if you execute a large query without any tasks that require the whole dataset before they can begin (ranks, ordering etc) the dynaset is created almost instantly and excel does not freeze up.
With non dynaset operations such as inserts it is possible to run the query in non blocking mode. I am able to monitor the progress of the query and indicate it to the user.
Dim myStatement As OraSqlStmt
Set myStatement = objdatabase.CreateSql(strSQL, ORASQL_NONBLK)
Do While myStatement.NonBlockingState = ORASQL_STILL_EXECUTING
DoEvents
Select Case intSpinCount
Case 1
Application.StatusBar = "Please Wait. Calculating data /"
Case 2
Application.StatusBar = "Please Wait. Calculating data -"
Case 3
Application.StatusBar = "Please Wait. Calculating data \"
Case 4
Application.StatusBar = "Please Wait. Calculating data |"
intSpinCount = 0
End Select
Application.Wait TimeSerial(Hour(Now()), Minute(Now()), Second(Now()) + 1)
intSpinCount = intSpinCount + 1
Loop
Non blocking mode is explained here. However dynasets are not supported.
http://download-west.oracle.com/docs/cd/A91202_01/901_doc/win.901/a90173/o4o00022.htm
I have tried using pl/sql to insert the data requested into a temporary table and then the normal select statement to get the data back out. However since the data stored in a table is not ordered it isnt much help to me since I still have to do the order by command.
Anyone got any ideas?
All help is much appreciated.

Dear taktang
I'm a newbie. I'd be grateful if you would tell me where to find "oracle-base"
thanks

PL/SQL Queries in OC

Is it possible to write normal SQL Queries into the Custom Code of OC?
for ex -
"select count(a.visdate) from tablename" or
"select max(col) from table name"?
is it also possible to write and set up CURSORS in OC like how we do normally in PLSQL of oracle.

Hi, Sorry for the late response, hope this helps.
You would need do the following.
"Declaration"- Create a cursor
"Pre-Details" - Use cursor
"Post-QG-A" Can specify the Qualifying Value here.
After doing the hard work, you can than use the cursor variables in the validation procedure.
Thanks,
Naveen

Dynamic SQL queries in HTMLDB application

How can i build a HTMLDB page only for dynamic sql queries like the features in the HTMLDB SQL-workshop.
I need a SQL interface for some power user running some ad-hoc queries.
Can i call this page directly from any other HTMLDB application?
Regards
Martin

Hello Martin,
I am a beginer in APEX but I have the same problem with you. What are your solution for dynamic sql query ? For report a solution is Pl Sql procedure which return a sql query. But for a form ?

Need analytical sql queries
