BUG #: 58065 (SQLBUG_70)

When you use the Microsoft SQL Server 7.0 Query Analyzer client tool with a smallint data type and a COMPUTE clause, unexpected results may be returned for the computed summary result. This behavior occurs only with negative numbers between -10000 and
-32768.

To work around this problem, use either of the following:
  • Use one of the following client tools instead:

    • OSQL or ISQL command line utilities to run the query.

      -or-

    • Use Microsoft SQL Server 6.5 ISQL_W or Microsoft SQL Server 2000 Query Analyzer to run the query.


  • Use the INT data type

Steps to Reproduce Behavior

Run this code:
if object_id('t1') is not nullDROP TABLE t1goCREATE TABLE t1 ( my_int smallint)goINSERT INTO t1 VALUES(-10000)INSERT INTO t1 VALUES (10000)goSELECT my_int FROM t1 COMPUTE MIN(my_int)go
Result:
my_int   ------ -1000010000min=====(unexpected result)(3 row(s) affected)
When you use OSQL to run the same query, this is the result:
C:\>osql -Usa -P1> USE mytest2> go1> SELECT my_int FROM t1 COMPUTE MIN(my_int)2> go
 my_int ------ -10000  10000 min ====== -10000
