BUG: Sp_columns Gives Incorrect Precision for View Substring

 * }

Q149915

-

The information in this article applies to:


 * Microsoft SQL Server version 6.0

-

BUG#: 14704 (6.00)

SYMPTOMS
Sp_columns incorrectly reports the precision of substring columns in views as 2147483647.

WORKAROUND
Recode the view to not have the substring.

STATUS
Microsoft has confirmed this to be a problem in SQL Server version 6.0. We are researching this problem and will post new information here as it becomes available.

This problem does not occur in version 6.50.

MORE INFORMATION
The type of view causing the problem is:

CREATE VIEW TestVw1 AS   Select ProbCol=substring(au_fname,1,1), au_fname from Authors

The large precision is reported up through the ODBC driver and can cause clients to think the column is a text column (for example, Microsoft Access treats the column as a memo column).
