How to use 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

This is my query. But it doesn't work correctly. The tow tables are not join properly. as well as the "Like" didn't work.

Answer 1

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

All you needed to do is add WHERE to your query.

Answer 2

Try this

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 3

You should only filter in your join statement when you want to filter the right table of your left outer join (here paimentDetl) . When you want to filter your left table (here pay_invoice_list) , you should add your filter clause in the where clause .

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

try like this

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

Put p.invoice_no in the WHERE clause.

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

This will return all records from pay_invoice_list where invoice_no LIKE ' %$temp%' and all records from paimentDetl where the invoice number matches.
