Mybatis中常见的SQL DML

1、sql select 查询

<select id="query"  resultType="CfCurrbusilogEntity" >
        select
                cb.bizid bizid,
                cb.phone phone,

                cb.systransno systransno,
                cb.responsecode responsecode,

                <!--

2、sql insert

 1 <!-- 插入数据 -->
 2     <insert id="insertBlack" parameterType="BlacklistEntity">
 3         INSERT INTO BLACKLIST

3、sql update

25         WHERE
26              BLACKID = #{blackid}

4、sql delete

1 <!-- 删除数据 -->
2     <delete id="deleteblack" parameterType="String">
3         DELETE FROM
4             BLACKLIST
5         WHERE
