在MyBatis中,删除数据的关键步骤如下:
<delete id="deleteUser" parameterType="int">
DELETE FROM user
WHERE id = #{id}
</delete>
public interface UserMapper {
void deleteUser(int id);
}
<mapper namespace="com.example.mapper.UserMapper">
<delete id="deleteUser" parameterType="int">
DELETE FROM user
WHERE id = #{id}
</delete>
</mapper>
UserMapper userMapper = sqlSession.getMapper(UserMapper.class);
userMapper.deleteUser(1);
这样就可以删除数据库中指定条件的数据了。
