方法1：[仅指定表名]java

select COLUMN_NAME from information_schema.COLUMNS where table_name = 'your-table-name';

方法2：[指定表名+数据库名]数据库

select COLUMN_NAME from information_schema.COLUMNS where table_name = 'your-table-name' and table_schema = 'your-DB-name';

========================那在mybatis中如何调用？====================mybatis

mapper.xml:app

 <select id="findFieldByTableName" parameterType="java.lang.String" resultType="java.lang.String">
        SELECT
            COLUMN_NAME
        FROM
            information_schema.COLUMNS
        WHERE
            table_name = #{tableName};
    </select>

mapper.javaspa

List<String> findFieldByTableName(@Param("tableName") String tableName);

调用便可获取！！code
