如何使用 JDBC 在 MySQL 中转义反斜杠?
若要转义反斜杠,请使用 PreparedStatement 来插入记录。首先,我们创建一个表 -
mysql> create table DemoTable1904 ( ClientId int, ClientName varchar(20), ClientAge int ); Query OK, 0 rows affected (0.00 sec)
Java 代码如下 -
import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; public class EscapeBackslashesDemo { public static void main(String[] args) { Connection con = null; PreparedStatement ps = null; try { con = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/web?" + "useSSL=false", "root", "123456"); String query = "insert into DemoTable1904(ClientId,ClientName,ClientAge) values(?,?,?) "; ps = con.prepareStatement(query); ps.setInt(1, 1001); ps.setString(2, "David Miller"); ps.setInt(3, 35); ps.executeUpdate(); System.out.println("One row is inserted....."); } catch (Exception e) { e.printStackTrace(); } } }
这将产生以下输出 -
我们来查看表记录 -
mysql> select * from DemoTable1904;
这将产生以下输出 -
+----------+--------------+-----------+ | ClientId | ClientName | ClientAge | +----------+--------------+-----------+ | 1001 | David Miller | 35 | +----------+--------------+-----------+ 1 row in set (0.00 sec)
