FIX: Bcp_batch Stops Responding After Interleaved Bcp_sendrow

• Microsoft SQL Server, version 6.5

SYMPTOMS

When you use two dbprocesses in one program to insert image/text data with the Bulk Copy Program (BCP) functions of DB-Library in two different tables, the program may stop responding on bcp_batch if you call bcp_sendrow and bcp_batch in the following order:

   for a = 1 to m
   {
      for i=1 to n
      {
         bcp_sendrow(process A)
         bcp_sendrow(process B)
      }

   bcp_batch(process A)
   bcp_batch(process B)
   }

WORKAROUND

To work around this problem, do any of the following:

• First call the BCP functions bcp_sendrow, bcp_batch, and bcp_done for process A, and then again for process B.
• Call the BCP functions for process A in one program and the ones for process B in another program.
• Set 'select into/bulkcopy' to false.
