Suppose if we want to see all the records of a table by passing its name as the parameter of a stored procedure then following example will create a procedure named ‘details’ which accepts the name of the table as its parameter −
mysql> DELIMITER // mysql> Create procedure details(tab_name Varchar(40)) -> BEGIN -> SET @t:= CONCAT('Select * from',' ',tab_name); -> Prepare stmt FROM @t; -> EXECUTE stmt; -> END // Query OK, 0 rows affected (0.00 sec)
Now invoke this procedure by giving the name of the table as its parameter and it will show all the records of that table.
mysql> DELIMITER; mysql> CALL details('student_detail'); +-----------+-------------+------------+ | Studentid | StudentName | address | +-----------+-------------+------------+ | 100 | Gaurav | Delhi | | 101 | Raman | Shimla | | 103 | Rahul | Jaipur | | 104 | Ram | Chandigarh | | 105 | Mohan | Chandigarh | +-----------+-------------+------------+ 5 rows in set (0.02 sec) Query OK, 0 rows affected (0.03 sec)
