  • Microsoft SQL Server 7.0
This article was previously published under Q248454
BUG #: 54557 (SQLBUG_70)

SYMPTOMS

An access violation may occur in the ODBC SQL Server driver if an application attempts to skip a column from the input data file using the bcp_colfmt function.

WORKAROUND

Extract out any column you need to skip from the input data file before bulk copying into the database.

STATUS

MORE INFORMATION

As defined by the SQL 7.0 Books Online (BOL) the bcp_colfmt function allows a value of 0 for the idxServerCol parameter. SQL BOL states:

If this value is 0, bulk copy ignores the column in the data file.

The Bcp.exe utility that ships with SQL 7.0 uses the bcp_colfmt function when a user specifies that a column is to be skipped through a "format file". A user can set the server column number field in the format file (the sixth field) to 0 to specify that a column is to be skipped from the input data file. For more information about Bcp.exe, see SQL 7.0 Books Online.
