How can I get all the records of a table by passing its name as the parameter of MySQL stored procedure?
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');
