MySQL stored procedure parameters don't seem to work with special character @?
You cannot give MySQL stored procedure parameter with @ in the beginning. You can give @ sign in user-defined variables.
Following is the syntax −
SET @yourVariableName=yourValue;
Let us implement the above syntax to correctly place @sign −
mysql> DELIMITER // mysql> CREATE PROCEDURE declare_Variable(IN StudentName varchar(100)) BEGIN SET @Name=StudentName; SELECT @Name; END // Query OK, 0 rows affected (0.12 sec) mysql> DELIMITER ;
Now you can call stored procedure with the help of CALL command −
mysql> call declare_Variable('John Smith');
This will produce the following output −
+------------+ | @Name | +------------+ | John Smith | +------------+ 1 row in set (0.00 sec) Query OK, 0 rows affected, 1 warning (0.03 sec)
