You do realise that VARDATA does not return a null terminated string?
I did not realize that... but it led me in the right direction.
Try using something like text_to_cstring or using elog(NOTICE) to
display what's actually being compared.
I've outputted some things with elog (which is the other thing I needed
to figure this out).
Using DatumToCString(mytextvariable), I get single-character-length
strings that do not match the data actually in the fields.
Using VARDATA(mytextvariable) as the char*, I get things like this (name
obscured) (using strlen to get the string's length):
string: "Hillary Clinton(6611)", length 21
string: "95555551234nton(6611)", length 21
Of course, then I realized that strlen isn't the right tool for the job;
I need: int len = VARSIZE(mytextvariable) - VARHDRSZ;
Using that with the VARDATA as my char*, I get this:
string: "Hillary Clinton(6611)" - length: 21
string: "95555551234" - length: 11
Which is what I need. Perhaps we could get some documentation about how
to use this stuff? I was unable to find any on the Postgres site, if
there is any.
Thanks for your help guys :)
