[mapserver-users] runtime substitution not working

[Joshua Hevenor]

I see what Ben was worried about and what you're trying to do. I haven't done a lot of variable substitution but I have done a lot of head scratching to when queries don't work as expected. A couple things that might shed some light you could try:

"like '%spp%'"    and  pass &spp=%TAR%

If you're looking for a string containing TAR.  It might confirm that the double %% are being misinterpreted. 

Or you could try if this is the case and you want to force the wildcards at the mapfile level. 
"like '%' || '%spp%' || '%"'

Hi Ben...

I have it working in other setups fine - just this one won't behave.

If I use "like '%spp%'" & pass &spp=TAR, then the query that gets run is
"like 'TAR', which is basically an un-indexed =

I need a "like '%TAR%'" in the SQL hence the double % sign. I have this working elsewhere fine (but with different versions of mapserver & Postgis)

Capitalisation might be the problem... I'll try that...


Thanks,

   Brent
