Her er en løsning til en enkelt kolonnesøgning ved hjælp af PATINDEX.
Den viser også StartPosition, InvalidCharacter og ASCII-koden.
select line,
patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) as [Position],
substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1) as [InvalidCharacter],
ascii(substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1)) as [ASCIICode]
from staging.APARMRE1
where patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) >0
