Hello,
Well, the subject line pretty much says it all. If any clarification
is needed, what I want to do is as follows:
SELECT * FROM table WHERE thisfield = 'some text';
How would I rewrite this query to search through the table looking at
the text in the column "thisfield" for the string "some text" but
have
it perform a case insensitive search?
SELECT * FROM table WHERE thisfield ilike 'some text';
Or SELECT * FROM table WHERE lower(thisfield) = lower('some text');
Which is less idiomatic than ilike, but has the advantage that
you can create a functional index on thisfield to allow the
query to use an index.
They'll both only search for an exact (but case-insensitive) match,
though - if what you're looking to do is look for any row where
thisfield contains 'some text' somewhere within it then that's an
entirely different thing and you'd want "... ilke '%some text%';"
Cheers,
Steve
