Error 2714 when parsing stored procedure

Posted on 2004-08-02
Last Modified: 2008-02-01
I have stored procedure with several IF statements. In each IF I use SELECT .. INTO #temp but I get error 2714 (table already exists).
It is not true becouse only one IF will be run.

What can I do?

Try Drop the temp table 1st if it's exist, like:

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[YourTableName]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[YourTableName]

No way. Table does'not exests. I put drop before all selects but still have error.

It's only parsing error. It should work correctly when run.

I had this and it is very frustrating. The best option :
1. If you're selecting the same columns, create the table upfront and use INSERT .. SELECT instead
2. If you're selecting out different columns/tables depending on the IF, use Dynamic SQL to create the table name; viz:
SELECT @sql="select * into #temptab from TableA"
EXEC (@sql)
Since Sybase doesn't see the select into at compile time, you avoid the error

I said Sybase when I meant SQL SERVER !
Works for both actually

after you have created temp table, don't forget to drop at the end of the sp, and before you start sp check that none of the temp tables exist and if they do drop them:

if object_id('#temp') is not null
   drop table #temp

FDzjuba, neither is necessary.
SQL appends the session ID to the temp table name (hence the 11-char name limit compared with 32 for permenant tables).
They are automatically destroyed when you exit a proc in which they were created.
As for checking for their existence, I wouls simply use a new name.

Hkamal is right.

It it realy bug of parser. Parser hates "double" creating temp table in different branches of IF.
