mmm...
Are you sure you want to ignore *any* number of non-numeric groups?
If so, one way would be denormalization... storing a second copy of
the part number in the table. This second part number would
represent the part number in a format that could be readily searched:
Real Part # Search Part #
-------------- --------------
12AB3456 123456
1AB23456 123456
123AB456 123456
Another way would be to use T/SQL statements, if the db is MS-SQL 7.
I would tend to recommend the denormalization... at the cost of a few
bytes in each record you greatly simplify the search process.
The input search field can be manipulated with regexp to easily
eliminate the non-numerics.
This isn't an electronics parts db, by any chance, it it>
