如何创建表并使用准备语句在该表中插入值？

可以通过以下示例来理解，在该示例中我们使用准备好的语句创建了名为“Student”的表 -

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)

现在，在使用准备好的语句进行以下查询的帮助下，我们可以在表“Student”中插入值

-

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)
