FIX: Bcp.exe with Long Query String Can Result in Assertion Failure (279180)

SYMPTOMS

The Bcp.exe command-line utility will accept a table name or a SELECT query as the source data specification. When using a lengthy SELECT statement, you may receive the following error message:

Assertion failed: sizeof(szCmd) > strlen(szCmd), file ..\src\bcpgetsf.c, line 50

RESOLUTION

To resolve this problem, obtain the latest service pack for Microsoft SQL Server 7.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

301511 INF: How to Obtain the Latest SQL Server 7.0 Service Pack

Note The following hotfix was created before the release of Microsoft SQL Server 7.0 Service Pack 4.

Hotfix

The English version of this fix should have the following file attributes or later:

   File name    Platform
   ---------------------
   BCP917.exe   Intel

Note The fix must be applied to the computer where you execute Bcp.exe because it is a client-side fix. Note Because of file dependencies, the most recent hotfix or feature that contains the files may also contain additional files.

MORE INFORMATION

The following is an example of Bcp.exe using the SELECT query syntax:

bcp "select au_lname, au_fname from pubs..authors" out c:\temp\delmt.exe -Usa -P -S

The problem occurs when the SELECT query is so long that it causes the command to be greater than the 414-byte limitation. After you apply the fix, the limit is approximately 1023 bytes. If you exceed 1023 bytes after you apply the fix, you will receive the following error message:

Query hints exceed maximum command buffer size of 1023 bytes
