The information in this article applies to:

Microsoft SQL Server 6.5

This article was previously published under Q170318

BUG #: 15818 (NT: 6.50)

SYMPTOMS

When attempting to insert the value 'NULL' into a timestamp column with ANSI_NULLS enabled, error 273 is returned:

The user can't INSERT a non-null value into a TIMESTAMP column. Use INSERT with a column list or with a default of NULL for the TIMESTAMP column.

WORKAROUND

To work around this problem, do either of the following:

Disable ANSI_NULLS before inserting NULL into a timestamp column, as in the following example:

      create table tblNull ( iId int, timestamp )
      go

      set ansi_nulls off
      go

      insert tblNull values (1, NULL)
      go

-or-

Use a column list on the INSERT statement and omit the timestamp, as in the following example:
```
      insert tblNull (iId) values (1)
      go

						
```

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
