这段代码是一个查询操作,使用了`a.Ts.Table()`方法指定查询的表为`business_base`,并将其别名为`a`。然后,使用`Select()`方法选择了一些字段,包括`a.bid`、`a.bname`、`a.status`、`a.ctime`、`u.user_name as admin_name`、`u.mobile as admin_mobile`、`b.contacts`、`b.phone`、`b.id_no`、`b.id_name`和`ifnull(u2.user_name,'') as operate_name`。
接下来,使用`Joins()`方法进行表连接操作,包括:
- `"inner join business_expand as b on a.bid=b.bid"`:将表`business_base`和表`business_expand`进行内连接,连接条件是它们的`bid`字段相等。
- `"left join user_base as u on a.admin_uid=u.uid"`:将表`business_base`和表`user_base`进行左连接,连接条件是它们的`admin_uid`和`uid`字段相等。
- `"left join user_base as u2 on a.cuid=u2.uid"`:将表`business_base`和表`user_base`进行左连接,连接条件是它们的`cuid`和`uid`字段相等。
以上操作将构建出一个完整的查询语句,并且可以执行该查询获取相应的结果。

func AppOperateRecharge(a *decorator.ApiBase) error { logger.AccessLogger.Info("AppOperateRecharge...") resp := adminStruct.BusinessOrderRechargeResponse{} resp.ResponseCommon = a.NewSuccessResponseCommon() a.Ts.Table("business_base as a"). Select("s.bid, a.bname, s.acct_bal,s.buy_sum_amt, " + "sum(CASE WHEN b.stmt_status = 1 THEN b.stmt_amt ELSE 0 END) as unpaid_amt, " + "sum(CASE WHEN b.stmt_status = 0 THEN b.stmt_amt ELSE 0 END) as stmt_amt, " + "a.admin_uid, u.user_name, a.status"). Joins("inner join business_bal as s on s.bid=a.bid"). Joins("inner join user_base as u on u.uid=a.admin_uid"). Joins("inner join business_settlement as b on b.bid=a.bid").返回所有数据
这段代码是一个名为`AppOperateRecharge`的函数,它接受一个名为`a`的指向`decorator.ApiBase`类型的指针作为参数,并返回一个`error`类型的值。
函数首先记录一条日志信息,然后创建一个名为`resp`的`adminStruct.BusinessOrderRechargeResponse`类型的变量。
接下来,函数给`resp`变量的`ResponseCommon`字段赋值为`a.NewSuccessResponseCommon()`,该方法返回一个表示成功响应的通用结构体。
然后,函数使用`a.Ts.Table`方法查询数据库中的数据,并将查询结果存储到`resp.Data`字段中。查询语句使用了多个`Joins`方法进行表连接操作,并使用了`Select`方法选择需要查询的字段。
最后,函数返回查询出来的所有数据,包括商家ID、商家名称、账面余额、采购货款等等。查询结果存储在`resp.Data`字段中。
func AppOperateRecharge(a *decorator.ApiBase) error { logger.AccessLogger.Info("AppOperateRecharge...") resp := adminStruct.BusinessOrderRecharge{} err := a.Ts.Table("business_base as a"). Select('a.bid, a.bname, a.acct_bal, a.buy_Sum_Amt,sum(CASE WHEN b.stmt_status = 1 THEN a.stmt_amt ELSE 0 END) as unpaid_amt, sum(CASE WHEN b.stmt_status = 0 THEN a.stmt_amt ELSE 0 END) as stmt_amt, a.admin_uid, a.user_name, a.status'). Joins("left join business_bal as s on s.bid=a.bid"). Joins("left join user_base as u on u.uid=a.admin_uid"). Joins("left join business_settlement as b on b.uid=a.bid"). Where("a.bid=?", a.Token.LinkId). Group("a.bid"). Scan(resp) if err != nil { return err } return a.ReturnSuccessCustomResponse(resp) }
在给出的代码中,你想要查询待结算商家的待结算货款和已结算货款,并将结果存储到结构体`BusinessOrderRecharge`中。为了实现这个目标,你需要对代码进行以下修改:
```go
func AppOperateRecharge(a *decorator.ApiBase) error {
logger.AccessLogger.Info("AppOperateRecharge...")
resp := adminStruct.BusinessOrderRecharge{}
err := a.Ts.Table("business_base as a").
Select("a.bid, a.bname, a.acct_bal, a.buy_Sum_Amt, sum(CASE WHEN b.stmt_status = 1 THEN a.stmt_amt ELSE 0 END) as unpaid_amt, sum(CASE WHEN b.stmt_status = 0 THEN a.stmt_amt ELSE 0 END) as stmt_amt, a.admin_uid, a.user_name, a.status").
Joins("left join business_bal as s on s.bid=a.bid").
Joins("left join user_base as u on u.uid=a.admin_uid").
Joins("left join business_settlement as b on b.uid=a.bid").
Where("a.bid=?", a.Token.LinkId).
Group("a.bid").
Scan(&resp)
if err != nil {
return err
}
return a.ReturnSuccessCustomResponse(resp)
}
```
在修改后的代码中,我更正了`Select`函数的参数,将单引号改为双引号,以正确表示字符串。同时,我还在`Scan`函数的参数中添加了取地址符`&`,以便将查询结果存储到结构体`resp`中。
请注意,这只是一个修改的示例,具体根据你的业务逻辑和数据结构来进行调整。
