如何使用准备语句更新表？

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更新了名为“Student”的表，其中包含以下数据 -

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

mysql> PREPARE stmt11 FROM 'UPDATE Student SET Name = ? WHERE Id = ?';
Query OK, 0 rows affected (0.03 sec)
Statement prepared

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

mysql> EXECUTE Stmt11 USING @A, @B;
Query OK, 1 row affected (0.05 sec)

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