Question
Complex Query - Remove Spaces and symbols (ONLY Alpha-Numeric)
I have a table with two types of addresses and I want to run a query on them that looks like this:
SELECT Address1, Address2
FROM tblMaster
WHERE ((Address2 Is Not Null) AND (Address1 <> Address2));
The only problem is some of the addresses have added spaces and hyphens that cause false-positives :(
So I am looking for a way to compare the two w/out the additional spaces and hyphens (and other symbols)...
So I need a SQL query that will compare the two fields w/out spaces and symbols (JUST Alpha-Numeric characters).
Any idea's ?
Thanks,
-BassKozz

You could do this in php.
I would use a regular expression that found all characters that were not alphanumeric
ie
not
[A-Z] [a-z] or [0-9]
and do a regular expression replace to replace those that meet the criteria with nothing.
I'd then use php to dump these results into a temporary table - and then run your query from there (that would be the fastest way)

Hi,
This depends on what version of mysql you are using.
If I were doing this with mysql 5.0 I would be building a function that cycles through all characters in the string and only return those that are alphanumeric - then doing a comparison using that function.
unfortunatley short of doing replaces on the other versions this is much harder to acheive.
