Article ID: 264005

APPLIES TO

Microsoft SQL Server 7.0 Service Pack 2

BUG #: 57944 (SQLBUG_70)

SYMPTOMS

An attempt to INSERT INTO a column that uses a declared variable may fail if the column has the same data type as the declared variable and the WHERE clause contains a subquery that uses either a NOT EXISTS or a NOT IN keyword. In such cases, the following error message occurs:

Server: Msg 8623, Level 16, State 2, Line 8
Internal Query Processor Error: The query processor could not produce a query plan.

WORKAROUND

The following scenario causes the error message to occur:

CREATE TABLE  #example_table( c1 int NULL )
DECLARE  @variable1  int
SET @variable1 = 1
INSERT #example_table ( c1 )
SELECT @variable1 WHERE NOT EXISTS 
(SELECT * FROM #example_table)

To work around this problem, use the CONVERT function to change the variable to the same data type.

In the preceding example, replace

SELECT  @variable1

with:

SELECT CONVERT(int,@variable1)
