Re: Case insensitive select

Thanks for the prompt reply, but while I was waiting for a reply I
discovered that using the RE operator '~*' will give me results, but if
in col1 there is are both 'value', and 'value1' and I look for value by
doing

SELECT * FROM test1 WHERE col1 ~* '^value';

I get both of them, value, and value1. 

(I freely admit I do not know much about regular expressions so I will
continue to read about them and see if I can get something to work for
me, but while I am working on that any more advice would be helpful!)

Also I did try ILIKE before I wrote the email and it did not work for me
unless I would put a % at the end of the string, eg.

SELECT * FROM test1 WHERE col1 ILIKE 'value';

would not return any results, but

SELECT * FROM test1 WHERE col1 ILIKE 'value%';

would return both the rows with value and value1. Neither of these are
acceptable, because I only want to find exact matches that are case
insensitive. I have been reading the documentation on operators and
functions but as of yet, have not discovered anything that will work
correctly 100% of the time. So once again I would appreciate any ideas
on why this may not be working for me.

Thanks again for the reply.
Isaac

There is also:

SELECT * FROM test1 WHERE col1 ~* '^value';
or:
SELECT * FROM test1 WHERE col1 ILIKE 'value';

See Operators and Functions in the online docs.
