Create table StgTemp
(
ID nvarchar(50)
)
INSERT INTO StgTemp values ('0003005')
INSERT INTO StgTemp values ('03405')
INSERT INTO StgTemp values ('1003005')
INSERT INTO StgTemp values ('3003005')
INSERT INTO StgTemp values ('35003005')
INSERT INTO StgTemp values ('823005')
INSERT INTO StgTemp values ('9205')
INSERT INTO StgTemp values ('9205')
INSERT INTO StgTemp values ('9205')
INSERT INTO StgTemp values ('920')
INSERT INTO StgTemp values ('35556005')
INSERT INTO StgTemp Values ('3678909')
SELECT * FROM StgTemp
Desired Output:
SELECT '3553005'
UNION
SELECT '3678909'
UNION
SELECT '823005'
UNION
SELECT '9205'
UNION
SELECT '920'
ID contains numeric values prevailing zeros in some cases so it is defined as varchar
how to get values starts with 3555 to 3999 and 8000 to 9999.
There is no specific rule that length is always 4.
Eg: 35551 , 3568887867988, 3590909,8000, 85805667,
all of the values are valid and are to be fetched.
Please let me know T- SQL statement for the above scenario

Cast to int and then it's simple to find values that fall in a certain range.

HI John if we cast 00003 will become 3 .I don't want to retrieve this value .It should start with 3 .
I have updated the question please check .

WITH ConverttoNumber AS ( SELECT ID , CAST(LEFT(ID + '000',4) AS int) AS Nbr FROM StgTemp ) SELECT DISTINCT ID FROM ConverttoNumber WHERE Nbr BETWEEN 3500 and 3999 OR Nbr BETWEEN 8000 and 9999

I'll might be missing something but I think that a simple select with range will do it:

SELECT distinct * FROM StgTemp where (ID >='3500' and ID <= '3999') or ID >='8000' and ID <= '9999'

Your simple solution won't pick up things like '008900'. Should it?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
