    Temp tables in mySQL stored procs not unique

    Would anyone know of a fix to this problem? I have a small stored proc that can get called many times a second. The basics of this are..

    Code:
    BEGIN
    
        CREATE TEMPORARY TABLE
          TEMP_BLAHH_BLAHH ( BLAHH_ID int ) ;
    
        -- A BIT OF WORK
    
    END $$
    The problem is that if 2 of these SPs are running at the same time then I get the following error...

    Table 'TEMP_BLAHH_BLAHH' already exists

    I am used to Sybase there the temp tables are totally unique to the SP's transaction.

    Does anyone know of a workaround/solution to this 'cos I have no idea?

    Thanks

    Strange, they should be per session/connection unique. But there is the "if not exists" option.

    Create temporary table if not exists blah.....

    Hope that helps.

      According to the blurb temp tables are unique per connection.

        Strange thing is that it does not happen on my windows dev machine but happens on my ubuntu server.

        If I was to use 'if not exists' then I would have to radically rework the procs and that could get messy.

        I also 'think' I am creating a new transaction each time in the code but I suppose anything is possible with an ORM framework. I should double check that with some debug.

            Use a proper database.
