Weird problem.

Re: Weird problem.

Well,
obviously (or perhaps not so) there is something wrong with your code. Also,
I'm not familiar with "IDENT_CURR ENT" - @@IDENTITY will do this for SQL
Server. Do you want to post a short-but-complete code sample so that you can
get some help?

And there's your problem. Use SELECT @@IDENTITY or, even better, SELECT
SCOPE_IDENTITY( )...

Except I don't want just some random IDENTITY value I want the last
IDENTITY value that was inserted into this specific table. And what
would that have to do with the data being returned?

In any case this is the stroed Proc that is executing but not
returning rows:

CREATE PROC [IMAGING\Padilla H].[spCreateAcquisi tion]
@FileUploadName varchar (50),
@AcquisitionID int
AS

SET NOCOUNT ON
--SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;

-- Variable Declarations
DECLARE @InternalAcquis itionID int;

--BEGIN TRAN

-- Insert initial values into table
INSERT INTO
Acquisition(
AcquisitionID,
[Filename],
AcquisitionStat usCode
)
VALUES
(
@AcquisitionID,
@FileUploadName ,
'U' );

--COMMIT

-- Get the Identity value that was last used in this table
SET @InternalAcquis itionID = IDENT_CURRENT(' Acquisition');

--Select the information back out for the entire row
SELECT
InternalAcquisi tionID,
AcquisitionID,
ServicerID,
'',
FileUploadDate,
TotalLoanCount,
LoansAssigned,
TotalLoanCount - LoansAssigned AS LoansUnassigned ,
TotalIndexes,
UnmatchedIndexe s,
TotalIndexes - UnmatchedIndexe s AS MatchedIndexes,
TotalProductCod es,
UnmatchedProduc tCodes,
TotalProductCod es - UnmatchedProduc tCodes AS MatchedProductC odes,
LastProcessedTi me,
Acquisition.Acq uisitionStatusC ode,
[Description],
[Filename]
FROM
Acquisition
INNER JOIN AcquisitionStat usCode
ON Acquisition.Acq uisitionStatusC ode =
AcquisitionStat usCode.Acquisit ionStatusCode
WHERE
InternalAcquisi tionID = @InternalAcquis itionID

The insert happens, I've verified that. The select layout gets back to
the code, I've verified that. But there is no data row that gets back
to the code. The SQLServer is on a different box than the code is
running on. I have a page before this that is getting rows back from
this table so it CAN happen.

I've tried setting dirty reads (it's commented out above). I've tried
setting transactions and then commit (also commented out). I can't get
the data to come back from this procedure.

In which case, you're using the wrong function - read the docs...

SET @InternalAcquis itionID = IDENT_CURRENT(' Acquisition');

SET @InternalAcquis itionID = SCOPE_IDENTITY( );

OK, someone's gonna have to explain that to me.

First off, it worked, thanks. (Dear God, thanks) But all that did is
confuse me even more.

IDENT_CURRENT was returning the correct identity. This is only now in
DEV so there are no others hitting the table to get confused with.
Besides, even if it wasn't returning the correct identity it should
have returned incorrect data, not nothing at all.

Does SCOPE_IDENTITY imply something about the transaction? Is that
what was happening? IDENT_CURRENT was abandonig the transaction or
something? But the identity it returned was correct... I've read both
articles and I don't get the difference. Please, if you could explain
better than MS I'd appreciate it.

And thanks again for the persistence in helping me.

Re: Weird problem.

The docs for IDENT_CURRENT:
Returns the last identity value generated for a specified table or view in
any session and any scope

That sounds like trouble to me but then, who am I right?

The docs say this for @@SCOPE_IDENTIT Y():
Returns the last identity value inserted into an identity column in the same
scope. A scope is a module: a stored procedure, trigger, function, or batch.
Therefore, two statements are in the same scope if they are in the same
stored procedure, function, or batch

Wow, sounds much safer to me...
