Using Crystal Reports 2008, I need to extract a date from a text field.

  • 0

Using Crystal Reports 2008, I need to extract a date from a text field. This date is usually in the format dd/mm/yy, but could also be entered as d/m/yy, dd/m/yyyy, etc.

This date could appear anywhere within the string.

At the moment I am relying on the fact that the date is placed at the end of the string, without a following fullstop, and using LEFT/RIGHT to extract each date part. These parts are then passed to another formula to create a full date:

Dim AllocationDate() as Date
If Not(IsNull({Command.Notes})) then
Formula = DateValue ((ToNumber ({@Year})), (ToNumber ({@Month})), (ToNumber ({@Day})))

However, if anyone uses a variation of format, adds a fullstop or more notes after the date the whole report keels over.

Is there any way I could extract this date by looking for a pattern? I’m guessing I could the use TRIM to get around the inconsistencies in format.

    And, as a last resort, you can try converting the multi-line string into a long string by replacing the special characters that represent CR, LF, etc. Replacing them with spaces or another innocuous character, and then treat the resultant string as if it were just a regular string (with the date in the middle).

    You would still have to make some assumptions to make this possible: ONE date per string, all special characters are known (or you have to test for all possible special characters), the date has SOME conformity to the format, etc.
