How can I create a table and insert values in that table using prepare statements?

MySQLMySQLi Database

It can be understood with the help of following the example in which we have created the table named ‘Student’ by using prepared statement −

mysql> PREPARE stmt3 FROM 'CREATE TABLE Student(Id INT, Name
Varchar(20))';
Query OK, 0 rows affected (0.00 sec)
Statement prepared

mysql> EXECUTE stmt3;
Query OK, 0 rows affected (0.73 sec)

mysql> DEALLOCATE PREPARE stmt3;
Query OK, 0 rows affected (0.00 sec)

Now, with the help of following queries using prepared statements, we can insert the values

in table ‘Student’ −

mysql> PREPARE stmt7 FROM 'INSERT INTO Student(Id,Name) values(?,?)';
Query OK, 0 rows affected (0.00 sec)
Statement prepared

mysql> SET @A = 1, @B = 'Ram';
Query OK, 0 rows affected (0.00 sec)

mysql> EXECUTE stmt7 using @A, @B;
Query OK, 1 row affected (0.04 sec)

mysql> SET @A = 2, @B = 'Shyam';
Query OK, 0 rows affected (0.00 sec)

mysql> EXECUTE stmt7 using @A, @B;
Query OK, 1 row affected (0.08 sec)

mysql> SET @A = 3, @B = 'Mohan';
Query OK, 0 rows affected (0.00 sec)

mysql> Select * from Student;
+------+-------+
| Id   | Name  |
+------+-------+
| 1    | Ram   |
| 2    | Shyam |
| 3    | Mohan |
+------+-------+
3 rows in set (0.00 sec)
