How can we access tables through MySQL stored procedures?
We can access one or all the tables from the MySQL stored procedure. Following is an example in which we created a stored procedure that will accept the name of the table as a parameter and after invoking it, will produce the result set with all the details from the table.
Example
mysql> Delimiter //
mysql> Create procedure access(tablename varchar(30))
-> BEGIN
-> SET @X := CONCAT('Select * from',' ',tablename);
-> Prepare statement from @X;
-> Execute statement;
-> END//
Query OK, 0 rows affected (0.16 sec)Now invoke the procedure with the table name, we need to access, as its parameter.
mysql> Delimiter ;
mysql> Call access('student_info');
