数据库执行结果和mybatis执行结果不一致

Question

使用：

SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@54b0f2cd] was not registered for synchronization because synchronization is not active
JDBC Connection [jdbc:mysql://xxxx/xxxx, UserName=xxxx@xxxx, MySQL-AB JDBC Driver] will not be managed by Spring
==>  Preparing: select IFNULL(count(*),0) from goods_info

SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@20bbe729] was not registered for synchronization because synchronization is not active

==>  Preparing: select IFNULL(sum(total_price),0) from order_build where order_status = '已支付' 
==> Parameters: 
<==    Columns: IFNULL(sum(total_price),0)
<==        Row: 0.00
<==      Total: 1

在数据库中，我除了四个sql，这里有日志：

<select id="getTotalMoney" resultType="String">
    select IFNULL(sum(total_price),0)
    from order_build
    where order_status =
    '已支付'
</select>

现在我发现前三个与数据库一致，但最后一个是错误。当我在数据库中执行它时，我可以得到正确的结果。

这是我的mapper.xml：

在数据库中，我得到了这个结果：

我很沮丧。我不知道为什么。
