Question

我想在以下条件下从mysql数据库中获取记录

我有以下表格：

organization_ Table
```
organizationId | organizationname
```

广告系列表

camp_id | camp_name | adv_id | organizationId

宣传表
```
adv_id | adv_name
```
ad_display表
```
ad_displayId | adv_id | camp_id |
```

现在从ad_display表我想要获取这样的记录：

| adv_name | camp_name | organizationname

将WHERE Condtion作为organizationId ==？

的位置

所以基本上我想要广告系列广告列表，其中organization_id =？

注意：camapign表中的同一个adv_id应该有多个条目，ad_display中有多个条目的同一个camp_id

Answer 1

试试这个：

SELECT ad.ad_displayId, a.adv_name, c.camp_name, o.organizationname 
FROM ad_display ad 
INNER JOIN advertise a ON ad.adv_id = a.adv_id 
INNER JOIN campaign c ON ad.camp_id = c.camp_id 
INNER JOIN organization o ON c.organizationId = o.organizationId 
WHERE o.organizationId = ?;

Answer 2

也许是这样的？

SELECT Distinct
  advertise.adv_name,
  campaign.camp_name,
  organization_.organizationname
FROM
  advertise inner join campaign
  on advertise.adv_id = campaign.adv_id
  inner join organization_
  on campaign.organizationID = organization_.organizationID
WHERE
  organization_.organizationID = 1

Answer 3

SELECT * FROM campaign
LEFT JOIN ad_display ON campaign.camp_id = ad_display.camp_id
LEFT JOIN advertise ON ad_display.adv_id = advertise.adv_id
WHERE campaign.organizationId = <?>

Answer 4

使用以下代码

SELECT dv_name,
       camp_name,
       organizationname
FROM   organization
       inner join campaign
               ON organization.organizationid == campaign.organizationid
       left join advertise
              ON campaign.adv_id == advertise.adv_id
WHERE  condition =? ;

Answer 5

SELECT  advertise.adv_name, 
        campaign.camp_name, 
        organization_Table.organizationname
FROM   ad_display 
    INNER JOIN advertise ON ad_display.adv_id = advertise.adv_id 
    INNER JOIN campaign ON ad_display.camp_id = campaign.camp_id 
    INNER JOIN organization_ Table ON campaign.organizationId = organization_Table.organizationId
    AND organization_Table.organizationId=?

Answer 6

SELECT batch_number,
       Count(receipt_number) AS tot_rec,
       Sum(amount)           AS tot_amount
FROM   receipt_header
GROUP  BY batch_number
UNION ALL
SELECT batch_number,
       Count(receipt_lines.receipt_number),
       Sum(receipt_lines.amount)
FROM   receipt_lines
       INNER JOIN receipt_header
               ON receipt_header.record_id = receipt_lines.header_record_id
GROUP  BY batch_number
ORDER  BY batch_number ASC;
