SSM一条整的sql语句传入报错

Question

一条整的sql语句传入报错,想搞懂这个问题的原因，

方法:

public List<daily_defray_total> complexSqlQuery(String sql){
return ddtMapper.complexSqlQuery(sql);
}

这里传入整条sql:

String defrayTotalSql = " SELECT * FROM daily_defray_total ";
    List<daily_defray_total> dailyDefrayTotalList = dailyDefrayTotalMapper.complexSqlQuery(defrayTotalSql);

在xml文件里 ,1和2都试过
1
<select id="complexSqlQuery" resultMap="BaseResultMap"parameterType="String"> #{0}
</select>

2
<select id="complexSqlQuery" resultMap="BaseResultMap" parameterType="java.lang.String"> #{sql,jdbcType=VARCHAR}
</select>

报错

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' SELECT * FROM daily_defray_total '' at line 1

真的是语法错了么,还是根本就没传入进去

Answer 1

SQL语句不用*号,用表的字段，
String defrayTotalSql = " SELECT u_id FROM daily_defray_total ";

<select id="complexSqlQuery"resultMap="BaseResultMap"parameterType="String">
${value}
</select>

Answer 2

1.我没有见过参数类型是String,貌似只有java.lang.String.
2.传递参数你要给用一个参数来接收.
