Question

I have following Table Structure :

Table: CashStatus (Can have duplicate entries for “ATM”)

ATM  Cash   Device
A01  55     BASE
A01  1      IST
A02  1      BASE
A02  78     IST

Table : ATM (Unique Entry for ATM Column)

ATM   DEVICE
A01   BASE
A02   IST

I want to retreive only those rows from CashStatus table who’s ATM & Device Column matches with as with ATM Table

I did some research and tried the following query:-

SELECT *
  FROM CashStatus 
 WHERE EXISTS (SELECT 'X'
                 FROM ATM
                WHERE ATM = TermId collate SQL_Latin1_General_CP1_CI_AS
               AND DeviceName = Devicetype collate SQL_Latin1_General_CP1_CI_AS);

But it gives error : Expression type int is invalid for COLLATE clause.

Answer 1

SELECT columnLists
FROM CashStatus cs JOIN ATM a ON cs.ATM = a.ATM AND cs.Device = a.Device

COLLATE is a keyword used to change language collations for columns; it’s never necessary on numeric datatypes, and probably unnecessary here (since you’re changing from one language to the same language).
