mysql stored-procedure: out parameter

by

Unable to replicate. It worked fine for me:

mysql> CALL my_sqrt(4, @out_value);
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT @out_value;
+------------+
| @out_value |
+------------+
| 2          | 
+------------+
1 row in set (0.00 sec)

Perhaps you should paste the entire error message instead of summarizing it.
