a.Ts.Table("business_base as a"). Select(`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, ifnull(u2.user_name,'') as operate_name `). Joins("inner join business_expand as b on a.bid=b.bid"). Joins("left join user_base as u on a.admin_uid=u.uid "). Joins("left join user_base as u2 on a.cuid=u2.uid ")

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.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').

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：

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。

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 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, u.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.bid=a.bid"). Group("a.bid").Offset(a.Offset). Limit(a.Size).Count(&resp.Count). Find(&resp.Data) return a.ReturnSuccessCustomResponse(resp) } 转为mysql语言查询

这段代码使用Golang的GORM库来构建一个MySQL查询语句。下面是将该代码转换为MySQL语言查询的版本：

SELECT 
    s.bid, a.bname, s.acct_bal, s.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, u.user_name, a.status
FROM
    business_base AS a
        LEFT JOIN
    business_bal AS s ON s.bid = a.bid
        LEFT JOIN
    user_base AS u ON u.uid = a.admin_uid
        LEFT JOIN
    business_settlement AS b ON b.bid = a.bid
WHERE
    a.bid = ?
GROUP BY a.bid
OFFSET ?
LIMIT ?

请注意，这是一个近似的转换，可能需要根据你的具体数据库结构和需求进行调整。在查询中，`?` 是占位符，表示查询参数的值，你需要将其替换为实际的值。另外，`OFFSET` 和 `LIMIT` 是用于分页的参数，你需要根据具体情况设置它们的值。
