How to return value of last autonum entered, Using Scope_Identity

I believe I have to use the Scope_Identity() function but not sure how to actually write it out to my page after it's returned. CODE NEW_PSR_SQL="INSERT INTO tbl_PSRs (PSR_Date, PSR_Text, PSR_Calc_Value, PSR_Override_Value, Is_Override) VALUES ('"&PSR_Date &"','"&PSR_Text &"'," &PSR_Calc_Value &"," &PSR_Override_Value &"," &PSR_Is_Override &") SELECT NEWID = SCOPE_IDENTITY() " set RsPSR=oConn.execute(NEW_PSR_SQL) response.write RsPSR(0) ' trying to return the last autonum from Scope_Identity() - not working The insert is working fine, but the code to write out the new ID is not working. Any ideas?

New D.I.C Head Joined: 12 Sep, 2007 Posts: 47 My Contributions	Ok so I'm sure I'm getting close but this is just not working: CODE PSR_ID_SQL="SELECT cast(SCOPE_IDENTITY() as bigint) AS tbl_PSRs" set RsPSR_ID = oConn.execute(PSR_ID_SQL) Response.write "The ID: " &RsPSR_ID(0) response.end The recordset appears to be empty, as nothing is displayed after the "The ID:" bit. I'm getting around this right now by requerying the table for the highest value in the field immediately after insert, but I know this could lead to severe problems if someone creates a record between the insert and the query. I really want to use Scope_Identity(). What am I missing?????????????????????????????????????????????????????

CODE NEW_PSR_SQL="INSERT INTO tbl_PSRs (PSR_Date, PSR_Text, PSR_Calc_Value, PSR_Override_Value, Is_Override) VALUES ('"&PSR_Date &"','"&PSR_Text &"'," &PSR_Calc_Value &"," &PSR_Override_Value &"," &PSR_Is_Override &") SELECT NEWID = @@IDENTITY "

Looks like old style ASP from here. You forgot a ";", e.g. CODE NEW_PSR_SQL="INSERT INTO tbl_PSRs (PSR_Date, PSR_Text, PSR_Calc_Value, PSR_Override_Value, Is_Override) VALUES ('"&PSR_Date &"','"&PSR_Text &"'," &PSR_Calc_Value &"," &PSR_Override_Value &"," &PSR_Is_Override &"); SELECT SCOPE_IDENTITY() " Also, avoid @@IDENTITY if you can help it. Basically, the older @@IDENTITY has a chance to get confused during multiple transactions. More here.

Don't see a link to that forum on the left tho... thought maybe someone would have an idea in this forum. I have read TONS about @@identity etc... vs. Scope_Identity() and I know enough to use Scope_Identity in this particular situation. All I'm really looking for is some code.. probably very simple... I have a data connection. I have a select statement. I do not have the last record Just Entered. If anyone has EVER done this in the past, and would like to share the one line of code I am looking for, I'd really appreciate it.
