Question $6$

Show customers $($customer ID$,$ postal code$)$ whose postal codes satisfy the following condition:

Each code has nine characters. All characters are digits except the sixth which is a dash $(-).$ On the other hand, the first character should always be $0.$ An example of a valid postal code is $01234-789.$

Please create a pattern match condition for postal code. Creating a condition for other columns $($e$.$g$.,$ country$)$ or using exact match will receive no credit.
