Question

I have query like

Select *
From ReportData L 
Left Join ATM A On L.ATMID=A.ATM 
Where L.ATMID=A.ATM AND L.IssuerNetwork < > '0000'

it retrieve result only when ATMID & ATM is like 'TWAW1800 ' & 'TWAW1800 ' But FAILS when 'TWAW1800' & 'TWAW1800 '

What i Tried is

Select *
From ReportData L 
Left Join ATM A On L.ATMID=A.ATM 
Where LTRIM(RTRIM(L.ATMID))=LTRIM(RTRIM(A.ATM)) AND L.IssuerNetwork < > '0000'

But it doesnt work for me..

Answer 1

Place the LTRIM()/RTRIM() on the JOIN so then it strips the whitespace when joining:

SELECT *
FROM ReportData L 
LEFT JOIN ATM A 
  ON LTRIM(RTRIM(L.ATMID))=LTRIM(RTRIM(A.ATM))
WHERE L.IssuerNetwork <> '0000'
