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.
