[英]MySQL return exact error/warning that stored procedure throws
This is my first time with Mysql SP. 这是我第一次使用Mysql SP。 I've a procedure that does several DML operations like inserts and updates.
我有一个执行一些DML操作(如插入和更新)的过程。 But it sometimes throws a warning.
但这有时会发出警告。 I want to show that exact warning as it is(on shell/console) when the script is executed.
我想显示执行脚本时的确切警告(在外壳/控制台上)。 Currently, I get something like below when an exception occurs.
当前,发生异常时,我得到类似下面的信息。
Query OK, 0 rows affected, 1 warning (0.08 sec)
When I execute the same procedure using a mysql client like workbench and execute the procedure. 当我使用像工作台之类的mysql客户端执行相同的过程并执行该过程时。 I get a proper error message.
我收到正确的错误消息。 This is what I want printed on console.
这就是我要在控制台上打印的内容。
1 10:33:03 call dbscripts(@param) 0 row(s) affected, 1 warning(s): 1062 Duplicate entry '124' for key 'PRIMARY'
How can I do this? 我怎样才能做到这一点?
Thanks 谢谢
