Question

Greetings,
I need to check whether the format of value stored database is correct. It should check for something like that:

x-x
x-xx
xx-xx
xxx-xxx
etc.

where xxx should be an integer. So the concept is to check if value has the following format: Integer – Integer

Answer 1

Try this –

select CASE WHEN (
charindex('-',columnName) > 0
AND
ISNUMERIC(left(columnName,(charindex('-',columnName)-1))) > 0
AND 
ISNUMERIC(right(columnName,(charindex('-',columnName)))) > 0
) THEN 1 ELSE 0 END as properWord 
from myTable

returns 1 if proper word else returns 0

EDIT: Works assuming you do not have any strings with consecutive ‘-‘ like ‘–‘ followed by numbers on both sides. Works for all other cases.
