BUG# NT: 13179 (6.00)

SYMPTOMS
If a text value of length 256 bytes is passed to a stored procedure as a parameter and in the stored procedure the DATALENGTH function is used to check the length of the parameter, it will return 0 instead of 256. If the text parameter's length is either greater than 256 or less than 256, the DATALENGTH function will return the correct length.

STATUS
Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.0. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server version 6.0. For more information, contact your primary support provider.
