FIX: Bcp_batch Stops Responding After Interleaved Bcp_sendrow

ID: Q164178

The information in this article applies to:

Microsoft SQL Server version 6.5

BUG #: 15926 (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)
   }

This problem only happens when the 'select into/bulkcopy' option is set in the database and BCP contains image/text data.

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.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.
