无法从 JDBC 执行 MySQL 存储过程

Question

Im trying to connect to the mariadb server in jdbc and call my stored procedure but im getting this error. Ive also tried:

'''GRANT all ON mysql.proc TO 'Gruppe18'@'i3ED6FBF0.versanet.det';'''

but in mysql i got access denied error.

And the server is from university so I dont have full access on it.

Answer 1

The image shows that you're using named parameters, which means that the JDBC driver needs to query the meta-data of the stored procedure to learn what those parameters are.

Your user is not authorized to query that meta-data.

Solution: Use positional parameters.
