[SOLVED] my substring() function does not work

[bulgin]

I have a table web2_access_log with a field request_uri that always has a uri as such in it:

 

/universe.jpg

/world.jpg

/stunning.jpg

 

I also have a cust database with file_names and email_addresses as such, for example:

 

file_names email_addresses

universe.jpg tom@yahoo.com

world.jpg jackie@hotmail.com

stunning.jpg toni@msn.com

 

I'm trying to get the matches between the data with the following command, and it works if I first manually remove the forward slash from each record in the web2_access_log field (can't do that all day long) , but not if I try to use the following formula.  What am I missing here?

 

SELECT substring( web2_access_log.request_uri

FROM 1 ), cust.file_names, cust.email_addresses

FROM web2_access_log

JOIN cust ON substring(web2_access_log.request_uri

FROM 1) = cust.file_names

 

I'm stumped and would appreciate any help that a guru could might spare.

 

Thanks!

Huh?

[MegamanNL]

SELECT SUBSTRING(web2_access_log.request_uri FROM 2)

 

or

 

SELECT SUBSTRING(web2_access_log.request_uri, 2)

 

Substring is 1-bases, not 0-based...

It turns out that the first recommendation above, which I did try, doesn't work, but the second one did:

 

This is what worked:

 

SELECT SUBSTRING(web2_access_log.request_uri, 2)

 

thanks for the suggestion and help!
