BUG #: 54663 (SQLBUG_70)

SYMPTOMS

The XCALL syntax option can be used when calling custom stored procedures. XCALL syntax specifies:

"Stored procedures handling UPDATE statements will be passed the original (that is, the "before" image) values for all columns."

However, if the update or delete takes place to an article with a published text or image column the Logreader can fail with this fatal message:

Error 18759. 'Replication failure.. File 'p:\sphinx\ntdbms\srvrepl\src\pfmt.cpp, line 443'.

Back to the top

SQL Server 7.0 does not contain the previous text or image value(s) in a format the Logreader can currently obtain. However, Logreader did not account for this fact and fails while attempting to retrieve these values.

MORE INFORMATION

This fix accounts for the fact that previous values cannot be obtained and passes "NULL" as the previous value for any text or image column when using XCALL.
