要实现动态传入表名、列名,需要做如下修改
- 添加属性statementType="STATEMENT"
- 同时sql里的属有变量取值都改成${xxxx},而不是#{xxx}
<insert id="insertSelectiveList" parameterType="java.util.Map" statementType="STATEMENT">
INSERT INTO ${tableName}(
user_no,
take_time,
created_at,
creator,
updated_at,
modifier
)VALUES
<foreach collection ="list" item="rateList" separator =",">
(${rateList.userNo},${rateList.takeTime}','${rateList.createdAt}', '${rateList.creator}', '${rateList.updatedAt}', '${rateList.modifier}')
</foreach >
</insert>
1. statementType:STATEMENT(非预编译),PREPARED(预编译)或CALLABLE中的任意一个,这就告诉 MyBatis 分别使用Statement,PreparedStatement或者CallableStatement。默认:PREPARED。这里显然不能使用预编译,要改成非预编译。
2. ${xxxx}:$将传入的数据直接显示生成在sql中,对于字符串数据,需要手动加上引号
