He will probably show you a valid sample, there's probably only one row that is not valid.

PONumber value is like
Example:'DSCL-07-12/Kit01'

07-12 is Month-Year
DSCL is a Fixed string so does Kit
only the 01 value gets change

Solution 1

Your error means what it says. The subtext is 'what sort of person stores strings when they mean to store dates ?' It's telling you that the substring you're grabbing, does not work out to be a valid date for every value it's pulling from the DB.

Solution 2

Check the PONumber value and try to figure out what the problem could be - if you are using a front end, try debugging through your code to check the value of PoNumber.

check 'PONumber' field

SUBSTRING(PONumber,6,2) is expressing months not date
this should be return value between 1 to 12 only.

so,check results of SUBSTRING(PONumber,6,2) like given below

SQL

select
cast(SUBSTRING(PONumber,6,2) as int)
from dbo.tbl_PO
where cast(SUBSTRING(PONumber,6,2) as  int)>12 or cast(SUBSTRING(PONumber,6,2) as  int)=0

Happy coding!
:)
