如何使用Like in left outer join

Question

SELECT * 
FROM pay_invoice_list p 
LEFT outer JOIN paimentDetl d 
on p.invoice_no= d.invoiceNo and p.invoice_no LIKE ' %$temp%' 
ORDER BY iid DESC 

这是我的查询。但它不能正常工作。拖车桌子没有正确连接。以及“喜欢”都不起作用。

Answer 1

尝试像在WHERE子句中这

SELECT * 
FROM pay_invoice_list p 
    LEFT outer JOIN paimentDetl d ON p.invoice_no = d.invoiceNo 
WHERE p.invoice_no LIKE ' %$temp%' 
ORDER BY iid DESC 

Answer 2

SELECT * 
FROM pay_invoice_list p 
LEFT outer JOIN paimentDetl d 
on p.invoice_no= d.invoiceNo 
Where p.invoice_no LIKE ' %$temp%' 
ORDER BY iid DESC 

您需要做的就是将WHERE添加到您的查询中。

Answer 3

当你想过滤的你left outer join（这里paimentDetl）右表试试这个

SELECT * 
FROM pay_invoice_list p 
LEFT outer JOIN paimentDetl d 
on p.invoice_no= d.invoiceNo 
where p.invoice_no LIKE ' %$temp%' 
ORDER BY iid DESC 

Answer 4

你应该在你join声明只能过滤。当你想过滤你的左表（这里是pay_invoice_list），你应该在where clause中添加你的过滤条款。

SELECT * 
FROM pay_invoice_list p 
LEFT outer JOIN paimentDetl d ON p.invoice_no= d.invoiceNo 
WHERE p.invoice_no LIKE '%$temp%' 
ORDER BY iid DESC 

Answer 5

认沽p.invoice_no。

SELECT * 
FROM pay_invoice_list p 
LEFT outer JOIN paimentDetl d on p.invoice_no= d.invoiceNo 
WHERE p.invoice_no LIKE ' %$temp%' 
ORDER BY iid DESC 

这将从pay_invoice_list invoice_no LIKE“％$ temp％”和所有记录paimentDetl发票号码匹配哪里哪里返回的所有记录。
