Package: libmyodbc
Version: 3.51.15r409-1+b1
Severity: normal
Hello,
Here is another report about stored procedures.
The attached code should run a simple stored procedure with an input and
an output parameter, but instead it fails with this error message:
Connecting
Creating procedure
Error 1304 HY000: [MySQL][ODBC 3.51
Driver][mysqld-5.0.45-Debian_1-log]PROCEDURE testfunc already exists
I found the documentation on calling stored procedures from ODBC in
here: http://technet.microsoft.com/en-us/library/ms403294.aspx
Calling the same procedure from inside MySQL works fine:
mysql> set @a=0;
Query OK, 0 rows affected (0.00 sec)
mysql> call testfunc(5, @a);
Query OK, 0 rows affected (0.00 sec)
mysql> select @a;
+------+
| @a |
+------+
| 5 |
+------+
1 row in set (0.01 sec)
Ciao,
Enrico
