Hi alia,

try this

select ( cast(RIGHT(max_rec,4) as integer)- cast(RIGHT(min_rec,4)as integer))

CONVERT(INT, STUFF(Max(max_rec), 1, 1, ''))- CONVERT(INT, STUFF(Min(min_rec), 1, 1, ''))as Received

I used this and got exact result as expected...

Solution 1

Use SUBSTRING() and LEN() :
SUBSTRING (Transact-SQL)[^]
LEN (Transact-SQL)[^]
