APPLIES TO

This article was previously published under Q175659
BUG #: 16074 (WINDOWS: 6.5)

SYMPTOMS

If you create an "oversized" table (that is, a table with a width greater than 1,962 bytes), you will receive the following message:
The total row size, 2575, for table 't1' exceeds the maximum number of
bytes per row, 1962.

If this table does not have an index and you execute a query with an ORDER BY clause (such as "SELECT * from t1 ORDER BY c1"), you will receive the following message:
Msg 416, Level 16 State 1
Create of work table failed because the row size would be 2575.
This exceeds the maximum allowable size of a row in a table, 2014.

WORKAROUND

To avoid this problem, use a statement similar to the following to create an index on the table: 
   create index ti on t1(c1)

STATUS

Microsoft has confirmed this to be a problem in SQL Server version 6.5. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.

   create table t1
