Ok I am investigating a query that someone developed for my company:

CAST(CAST(SUBSTRING(KeyField, 7, 10) AS BIGINT) AS varchar) AS OrderLineLink

The keyfield column has data such as....
0000230008    retult....    8
0000290004    result....   4

but now im getting data in the Keyfield such as...

000023AER8

This is obv causing a crash. If the conversion is not possible how can I get it to use null?

Actually, sorry to change the question slightly, but ive just noticed it needs to start far right and move left until it hits aa zero, so....

0000290004  = 4
0000290014  = 14
0000290144  = 144

Thank you.
