Get the Last Value of Status Field from SQL TABLE using SQL 2008

I have a table with Fields such as
UploadstartTime, UploadEndtime, STATUS From TBLA.
The STATUS Field, has values =7 and 11 are failed and 12 is SUCCESS. I cannot do a max, since it will always show 12, I need to get the MAX(UPLOADENDTIME, and get STATUS For that record. How can I do that using 1 SQL Query?
My current code is: The issue is
select
TBLNAME
MaxUploadstarttime
=
max(UploadStartTime),
MaxUploadEndtime
=
max(UpLoadEndTime),
Status=max(status)
from DB.DBO.LOGTABLE

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. You failed! Temporal
data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I have a table with Fields such as <<
Fields are not columns! There is no generic status in RDBMS. Putting “tbl-” in a table name is called tibbling and we make fun of people who do it (Google Phil Factor's humor columns. If you were polite is this what you wanted to post?
CREATE TABLE Something_Uploads

How to compare, current value in :block.text_item with the database value

Hi
Could you please tell me
How to compare the current value in :block.text_item with the corresponding database column value.
I am using forms 10g
There is block and there is an text Item in that block.
When I run the form and query the block (tabular), the :block.text_item shows me, whatever value there in the database.
Now I add some value in the :block.text_item to the existing value.
now
the :block.text_item contains old+ new added value
whereas
the database table contains 'old' value
Now on a button click , I want to find out what is the value that I have added
Could you please tell me, is it possible without writing a select query?

Hello,
Now on a button click , I want to find out what is the value that I have addedSo you mean always user will add value in the existing value. Because this way will fail in one case. Let say
Value in Database is = ABCD
User opened the form and he removed the D and write E and now value is ABCE and length is still same 4. So, there is no addition.
Anyway you can know the database value at runtime there is one property for item called DATABASE_VALUE. It gives the value which is in database while you are running the form before save. and you can use like this..
Trigger = WHEN-MOUSE-DOUBLE-CLICK on item level
DECLARE
vItemValue DATATYPE; -- Set the data type according to your desired field.
vValueAdded DATATYPE; -- Set the data type according to your desired field.
BEGIN
vItemValue:=GET_ITEM_PROPERTY('ITEM_NAME',DATABASE_VALUE); -- It will return you the database value in vItemValue variable.
IF LENGTH(vItemValue)>LENGTH(:FORM_ITEM_NAME) THEN -- It mean something change or added
vValueAdded:=SUBSTR(:FORM_ITEM_NAME,LENGTH(vItemValue)+1);
MESSAGE('Added value is : '||vValueAdded); -- It will show you the added value.
END IF;
-- now suppose you want to show the old and new value in message not the added one
-- Then no need of IF condition. You can just use message like this
-- And i would prefer to use like this way
MESSAGE('Old Value : '||vItemValue||' New Value - '||:FORM_ITEM_NAME);
MESSAGE('Old Value : '||vItemValue||' New Value - '||:FORM_ITEM_NAME);
END;Hope it is clear.

Compare the current value with the previous value in the same column

Hi all,
I have to include a statement in a query which allows to compare the current value of column A with the previous value of column A (same column). from there, I need to add a condition in order to have the expected result.
Let's take an example to illustrate what I want to achieve:
I have the following columns in table called 'Charges':
Ship_id batch_nr Order_nr Price
SID1111 9997 MD5551 50
SID1111 9998 MD5552 50
SID1111 9999 MD5553 50
SID2222 8887 MD6661 80
SID2222 8887 MD6662 80
SID2222 8887 MD6662 80
SID3333 6666 MD7771 90
I want to check if the ship_id of row 2,3 (and more if available) is equal to the ship_id of row 1.
If it is the case, then value 'together with the first batch_nr' in row 2 and 3 under Price column. If not, then keep the original value of Price column
PLease see below the expected result:
Ship_id batch_nr Order_nr Price
SID1111 9997 MD5551 50
SID1111 9998 MD5552 together with 9997
SID1111 9999 MD5553 together with 9997
SID2222 8887 MD6661 80
SID2222 8887 MD6662 together with 8887
SID2222 8887 MD6663 together with 8887
SID3333 6666 MD7771 90
Thanks in advance for your help, it is really urgent.

]That looks like the query you were using before you started this thread.
Modify it, using the analytic fucntions FIRST_VALUE and LAG, like I showed you.
I see that you did simplify the problem quite a bit, and it's good that you did that.
It doesn't matter that your real problem involves joins or GROUP BY. Analytic functions are calculated on the results after all joins and GROUPS BYs are done. Just substitute your real expressions for the simplified ones.
For example, in your simplified problem, there was a column called order_nr, but I see now that's it's really called o.ordnum. Where the solution I posted earlier says "ORDER BY order_nr", you should say "ORDER BY o.ordnum".
Here's a less obvious example: in your simplifed problem, there was a column called price, but I see now that it's really SUM (tc1.chrg_amt + tc2.chrg_amt + tc3.chrg_amt). Where the solution I posted earlier says "TO_CHAR (price)", you should say "TO_CHAR (SUM (tc1.chrg_amt + tc2.chrg_amt + tc3.chrg_amt))". (You can't use an alias, like "Total Price", in the same SELECT clasue where it is defined.)
I removed some columns from the select as they are not relevant for the wanted action like 'adress details or other references'.
Now here is the result:
Shipment ID     Order Number     WMS Batch     Freight      Fuel Price Order Total Price
SID0132408     MDK-000014-05602649     04641401     110     10 120
SID0132408     MDK-000014-05602651     04641402     110     10 120
SID0132408     MDK-000014-05602652     04641363     110     10 120
as you can see, the 3 orders have the same shipment ID.
The expected result should be shown under column 'Total Price' as follows:
Shipment ID     Order Number     WMS Batch     Freight      Fuel Price Order Total Price
SID0132408     MDK-000014-05602649     04641401     110     10 120
SID0132408     MDK-000014-05602651     04641402     110     10 tog with 04641401
SID0132408     MDK-000014-05602652     04641363     110     10 tog with 04641401Okay, so those are the correct results that I asked for, plus the incorrect results you're getting now. Thanks; extra information doesn't hurt.
But where is the raw data that you're starting with?
It looks like you tried to format the code (but not the results) by typing this 1 character:
before the formatted section and this different character
after the formatted section. To post formatted text on this site, type these 6 characters
before the formatted section, and the exact same 6 characters again after the formatted section.

Refreshing the value of a field in a table and displaying it on the screen.

how do i mimimize calls to the database in the following scenario?
I need to show the latest value of a field in a table in a database through a java program. in a concurrent access environment, there are chances of multiple users getting stale values. how do I overcome this problem through code?
please advise.

There are many ways of doing this. However its worth noting that RDBMS database are not messaging, event driven systems and are not best suited to do what you want to do. You should only consider doing this if you have a low rate of changes.
You can
- Poll the database table and look for changes.
- Add a trigger to the table to record the keys which have changed. The have a query to find just the key which have changed.
- When a field changes, also send a broadcast/topic message.
- Add a trigger which sends a JMS message when a change occurs. (This is entirely DB/JMS specific, you need to find if this is possible)
Again, databases are not ideally suited to event driven, real time updates. There is no simple, clean solution.

How to get the current values of LINESIZE and WRAP in SQLplus ?

How do I get the current values for the SQLplus environment variables
e.g. LINESIZE, WRAP, PAGESIZE ?
When I type
SQL> show parameter LINESIZE
nothing is displayed.
Is there a command to show ALL existing current paramter values at once ?

SQL> show linesize
linesize 134
SQL> show wrap
wrap : regels zullen omgeslagen worden
SQL> show pagesize
pagesize 50000And you can issue a "show all" to see all settings at once.

How to display the current value selected in DDLB of another screen

hi Experts
I need some info regarding the dropdownlist in BSP.
I have two screens . One screen contains the table view which contains a set of records.Each record has two columns.
Second screen contains 2 drop down list.
When i select one record and then press the submit button in the first screen .Then i want that the selected value of the selected record will display in the DDLB of the second screen. And then i can again select the value from the drop down list.
For example:
1st screen:
record 1.
col 1     col 2
record 2
col 1     col 2
2nd screen
ddlb1...........
ddlb2...........
So when i select the record1, then the current value of col1 and col2 should visible on the ddlbs of second screen first time. Then i choose other value from the ddlbs.....
My Question is how to do the following
"when i select the record1, then the current value of col1 and col2 should visible on the ddlbs of second screen".
please provide some suggestions...
Thanks.

Hi,
You can use form with post method
like
<htmlb:form method = "post"
                  action = "page2.htm"
                  target = "coding" >
<htmlb:dropdownListBox id             = "labelAlignment"
                                           selection      = "<%= me->labelAlignment %>"
                                           onClientSelect = "document.forms[0].submit();" >
                      <htmlb:listBoxItem key   = "LEFT"
                                         value = "LEFT" />
                      <htmlb:listBoxItem key   = "RIGHT"
                                         value = "RIGHT" />
                    </htmlb:dropdownListBox>
So once you select col1 and col2 in your case its value is in page attribute say hold, this attributes needs to be defined in page2.htm also with auto checked. You can get the val selected in page1.htm
If helpful rewards point.

The VI cannot be running, so you need to set it from a different VI. (It also means, it cannot set itself.)

Get the current value of a managed bean.

Hi guys
I have a register page which takes the Login ID and the password and retype password whose values are stored in the "Managed Beans" in registerServer.java.
I have a (PwdValidator.java) Custom validator for Re-type Password which validates itself against the password.
Now my problem is from the PwdValidator.java how can I access the value of the password which is stored in the managed bean in registerServer.java.
here is a copy of my faces-config.xml
     <managed-bean>
          <managed-bean-name>registerServer</managed-bean-name>
          <managed-bean-class>com.sun.registerServer</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
     </managed-bean>
Help is really appreciated,
Thanks,
Chaprasi Baba

Thanks for the reply but my question is how do I get
the password value from the managed bean
FacesContext context =
FacesContext.getCurrentInstance();
Application application = context.getApplication();
CountryValueObject registerServer =
(CountryValueObject)application.getVariableResolver().r
solveVariable(context, "registerServer");
String pwd = registerServer.password // So will this
give me the current value for that session.You didn't go far enough in replacing the example code . Try this:
FacesContext context = FacesContext.getCurrentInstance();
Application application = context.getApplication();
RegisterServer registerServer = (RegisterServer)application.getVariableResolver().resolveVariable(context, "registerServer");
String pwd = registerServer.password // So will this give me the current value for that session.

Select List with the current value

Hi,
I have a Page suppose Page1 with 2 region.
Region1 is having SEARCH button (target page 1 itself) and a SELECT LIST called Deptno (10,20,30,40)
Region2 is just a simple employee report based on Deptno (where deptno = :p1_deptno)
Now when I suppose select deptno 30 and press SEARCH button, report is not displayed and also Dept select list current value becomes the first one in the list i.e 10.
My question is after submitting the same page 1 using SEARCH button, how can I display the selected value (dept 30) in the select list.
Note:- If I am using Select List with Submit then it's working fine and also displaying the current value (30) in the list, But I am looking for using SEARCH button.
Thanks,
Deepak

Hi,
Then the value that is selected in the list will not be submitted, so it will not be saved. You need a button that submits the page.

Comparing the current value with the previous one in Powershell

Hi,
New to scripting and i was wondering how can I compare the current value with the previous value?
I am having trouble with the loop structure, and I am not sure I am on the right track...
I am trying to compare the record to next record in the same csv file after import-csv... My code runs fine, but is not giving the right result.
$FilePath = Get-FileName -initialDirectory "C:\"
#Testing for null
If($FilePath)
$Data = Import-csv -Path $FilePath | Sort-Object BUYER, {[int] $_.PO_NBR}, {[int] $_.LINE_NBR}
Foreach($fData in $Data)
$i = $fData
Foreach($i in $fData)
if($fData.Buyer -eq $i.Buyer)
#save all the same buyer name to a new variable
Write-Host "Same as previous"
Else
Write-Host "Variable is null"
Remove-Item function:\Get-FileName

Thank you. The Foreach loop is now working properly.
Can I ask what is the purpose of "-ea 0" in the import-csv? I can't seem to find "-ea" as a parameter for import-csv in help.
-ea is short for -ErrorAction.

Updating a database value when you don't have the current value

I need to write a query that updates the amount of points a
user has, even though i don't know how many they have currently.
This is part of a referal program. When a user gets another user to
join, the original user gets 15 more points. The problem is I do
not want to write a query that finds how many points the original
user has because that seems wasteful. It should look something
like..
<cfquery datasource="users" name="givepoints">
Update users
set points = [whatever the current value is + 15]
where userlogin = form.referer
</cfquery>
That line that has the value in the brackets is where i am
confused. I don't know the current value so how can i add 15 to
it?

In some databases, oracle for example, the use of
cfqueryparam speeds up your queries. It also has the potential to
simplify your code in that it handles things like apostrophes, so
you don't have to.
On the other hand, if you want to cache your query, you can't
use cfqueryparam. Also, if you are using some sort of logic to
build an sql variable to use in your query, it takes a lot of
effort (more than I'm prepared to give) to use cfqueryparam.
Also, not every db supports it.
cfqueryparam has it's place, but that place is not
everywhere.

ExecuteWithParams, bindVariable don´t take the current value of textfield

Hello,
i use a bind variable to select only the rows with the same date. (ExecuteWithParams)
Therefor i added the bind Variable as a JTextfield to my client.
If i type the date to the textfield it works, but if i add current date by pressing a button, the filter ignores the value of the textfield.
After a mouseklick into the textfield it works again.
Thank you

Hi,
how do you add the current date? You should set the date in the binding layer if you want it to also show in the textfield. The panelBining variable is a handle to the binding. From here you can cal get("name of the attribute"), cast it to control binding and cal setInputValue

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks
