Question

I have a database that has two tables that need to be linked, but in one table the data is padded with zeros. For example, the tables may look like this:

CUSTOMER.CUSTNUM = 00000000123456

CUSTOMERPHONE.CUSTNUM = 123456

I can’t figure out how to get these tables to properly join.

What I’m trying to do now is trick Crystal Reports into specifying the Join clause by adding the following to the selection expert:

Right ({CUSTOMER.CUSTNUM}) = {CUSTOMERPHONE.CUSTNUM}

That’s not working though, and I get no records at all in my report.

Any ideas?

Answer 1

Crystal doesn’t like heterogeneous joins.

Options:

• use a command object, which will give you more control over the linkage
• create a SQL Expression that performs the desired concatination; link fields in the record-selection formula
• use a subreport for the linked table
• alter the table to make the data types compatible
• create a SQL view that performs the joins
