BUG: SELECT INTO Does Not Raise Error with No Column Name |
Q105336
The information in this article applies to:
- Microsoft SQL Server version 4.2x
BUG# NT: 489 (4.2)
SYMPTOMS
If a table is created using SELECT INTO, and no column name is given, sp_help <tablename> returns error 515:
attempt to insert the value NULL into column <col_name>, table tempdb.dbo.#sphelptab_.....column does not allow nulls.
Retrievals and updates of the data work fine on the table. Select * on the table shows that some of the columns have NULL column names.
CAUSE
The SELECT INTO statement puts a NULL for the column name when aggregate function is used and no column name is given. A table should not have NULL column names.
For example:
select count(*), title_id into t from titles
creates table t with two columns: NULL, and title_id. Sp_help t gives error 515.
WORKAROUND
Make sure the columns names are supplied when using SELECT INTO.
For example:
select cnt=count(*), title_id into t from titles
STATUS
Microsoft has confirmed this to be a problem in SQL Server version 4.2.
