Parameter number X is not an OUT parameter

摘要: 解决java.sql.SQLException: Parameter number X is not an OUT parameter

开发过程中遇到这个问题，试着按网上的方式解决：

只能说然并卵。

其实，有可能是连接mysql的用户没有procedure的执行权限导致的。
此次我碰到的问题就是这样，记录下来！

GRANT EXECUTE ON ichson_lore_source.* TO 'loresource_opr'@'%';
GRANT SELECT ON `mysql`.`proc` TO 'loresource_opr'@'%'

没有授予EXECUTE的权限，也是报出如下的错误：

### Cause: java.sql.SQLException: Parameter number 2 is not an OUT parameter

如果不授予

mysql

.

proc

的权限，会报metadata没有权限的问题。
