Question

I tried with this query but no luck :

SELECT tr.transferfrom, tr.transferto, br.id as 'BR_ID',
  tr.refno, br.name as 'BR_NAME', br.code as 'BRANCH_CODE',
  tr.docno, tr.transdate, stk.stockno,stk.salescat,tr.qty,
  tr.sprice,tr.qty*tr.sprice as 'GROSS_SALES' 
FROM TRANSFER tr 
JOIN branch br on tr.branchid=br.id 
JOIN stocks stk on tr.stockid=stk.id 
WHERE (tr.docno = 'ST00576' AND br.id IN ('*')) 
OR RIGHT(tr.refno,7) = 'ST00576' AND LEFT(tr.refno,3) IN ('*')

I wanted to have query to select ALL records if the br.id is a blank value.

Answer 1

Have a subquery that gets all the branch ids and then the IN query can refer to the output of the subquery.. the subquery will be like select br.id from branch br

Thus the entire query will look like:

SELECT 
  tr.transferfrom, 
  tr.transferto, 
  br.id as 'BR_ID',
  tr.refno,
  br.name as 'BR_NAME', 
  br.code as 'BRANCH_CODE', 
  tr.docno,
  tr.transdate, 
  stk.stockno,
  stk.salescat,
  tr.qty,
  tr.sprice,
  tr.qty*tr.sprice as 'GROSS_SALES' 
FROM TRANSFER tr 
  JOIN branch br 
    on tr.branchid=br.id 
  JOIN stocks stk 
    on tr.stockid=stk.id
WHERE (
  tr.docno = 'ST00576' 
  AND br.id IN (select br.id from branch br)
  ) 
  OR RIGHT(tr.refno,7) = 'ST00576' 
  AND LEFT(tr.refno,3) IN ( select br.id from branch br)
