show create procedure pro_salgrade\G ERROR 1305 (42000): PROCEDURE pro_salgrade does not exist

The error message "ERROR 1305 (42000): PROCEDURE pro_salgrade does not exist" indicates that the stored procedure "pro_salgrade" does not exist in the current schema or database.

Make sure that you are connected to the correct database where the "pro_salgrade" stored procedure is created. You can use the following command to switch to the desired database:

USE database_name;

Replace "database_name" with the name of the database that you want to use.

If the stored procedure does not exist, you can create it using the CREATE PROCEDURE statement. Here is an example:

CREATE PROCEDURE pro_salgrade()
BEGIN
   -- stored procedure logic
END;

Replace the "-- stored procedure logic" with the actual SQL statements that you want the stored procedure to execute. After creating the stored procedure, you should be able to use the SHOW CREATE PROCEDURE command to display its create statement.
