we recently migrated to ssrs 2017 from an older version and on certain reports, where we utilize ISDATE the report returns an argument and does not run, here is the case statement in the query
CASE WHEN ISDATE(or_shby) = 1 THEN CONVERT(DATE,or_shby) ELSE NULL END AS or_shby,
here is the argument error
Msg 8116, Level 16, State 1, Line 5 Argument data type date is invalid for argument 1 of isdate function.
Any help would be appreciated
Thank you
