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.



WORKAROUND

 * 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 null DROP TABLE t1 go CREATE TABLE t1 ( my_int smallint) go INSERT INTO t1 VALUES(-10000) INSERT INTO t1 VALUES (10000) go SELECT my_int FROM t1 COMPUTE MIN(my_int) go Result:

my_int -- -10000 10000

min

=
(unexpected result)

(3 row(s) affected) When you use OSQL to run the same query, this is the result: C:\>osql -Usa -P 1> USE mytest 2> go 1> SELECT my_int FROM t1 COMPUTE MIN(my_int) 2> go  my_int -- -10000 10000

min ====== -10000
