Mysql 需要关于编写SQL联接查询的帮助吗

我有一张名为“客户请求”的表格：

和一张名为“作业”的表格：

我想编写一个选择查询，从两个表中选择所有条目，并在下表中显示它们：

[QuoteNumber] (refers to CustomerRequestID in customer_requests, and fkCustomerRequestID in job)

[JobNumber] (refers to JobID in job, and is blank if the entry is from customer_requests)

[CustomerName] (selected using fkCustomerID in customer_requests, selected using fkCustomerRequestID->fkCustomerID in job)

[SupplierName] (selected using fkSupplierID in job, blank if entry is from customer_requests)

[JobTitle] (refers to title in customer_requests, and JobTitle in job)

[Quantity] (refers to QuantityRequested in customer_requests, and Quantity in Job)

[Cost]  (refers to GrossSellPrice in customer_requests and Cost in Job)

[ETA] (refers to ETA in Job, and blank if the entry is from customer_requests)

[Status] (refers to Status in customer_requests, and Status in Job)

我如何将这两个表连接在一起制作此表？

我假设您也有表供应商和客户：

INSERT INTO NEWTABLENAME
SELECT j.fkCustomerRequestID,
    j.JobID,
    c.CustomerName,
    s.supplierName,
    j.JobTitle,
    j.Quantity,
    j.Cost,
    j.ETA,
    j.STATUS
FROM Jobs j
INNER JOIN supplier s ON j.fkSupplierID = s.SupplierID
INNER JOIN customer c ON j.fkCustomerRequestID = c.customerID

编辑：

如果需要两个表中的所有信息，可以执行上面的查询，然后使用以下查询启用所有信息：

SELECT cr.fkCustomerRequestID,
    "",
    c.CustomerName,
    "",
    cr.title,
    cr.QuantityRequested,
    cr.GrossSellPrice,
    "",
    cr.STATUS
FROM Jobs customer_requests
INNER JOIN customer c ON cr.fkCustomerID = c.customerID

你能告诉我们你尝试过什么吗？一些类似的东西：$query=“SELECT*FROM

job

”$jobResult=mysql\u query（$query）$query=“从客户请求中选择*”$quoteResult=mysql_查询（$query）；while（$row=mysql\u fetch\u数组（$result））{这个问题似乎离题了，因为它无法证明对正在解决的问题的最低理解。不幸的是，这不起作用。我需要它做的是从customer_请求和job（基本上是一个联合）中选择所有条目。因此，新表将由customer请求和job组成。@BlakeSiviour。我是edi我的答案。看看它是否更近。如果它不是你想要的，考虑用表格和一些例子信息创建一个AN！这是有效的。谢谢。

INSERT INTO NEWTABLENAME
SELECT j.fkCustomerRequestID,
    j.JobID,
    c.CustomerName,
    s.supplierName,
    j.JobTitle,
    j.Quantity,
    j.Cost,
    j.ETA,
    j.STATUS
FROM Jobs j
INNER JOIN supplier s ON j.fkSupplierID = s.SupplierID
INNER JOIN customer c ON j.fkCustomerRequestID = c.customerID

SELECT cr.fkCustomerRequestID,
    "",
    c.CustomerName,
    "",
    cr.title,
    cr.QuantityRequested,
    cr.GrossSellPrice,
    "",
    cr.STATUS
FROM Jobs customer_requests
INNER JOIN customer c ON cr.fkCustomerID = c.customerID
