I have a text column in a table, which I want to search through --
seeking the occurrence of about 300 small strings in it.
Let's say the table is like this:
table1 (
id bigint primary key
,mytext text
,mydate timestamp without time zone
);
I am using this SQL:
SELECT id FROM table1
WHERE mytext ~* E'sub1|sub2|sub3|sub4...'
LIMIT 10;
This is basically working, but some of the "mytext" columns being
returned that do not contain any of these substrings. Am I doing the
POSIX regexp wrongly? This same thing works when I try it in PHP with
preg_match. But not in Postgresql. I have tried several variations
too:
WHERE mytext ~* E'(sub1)(sub2)(sub3)(sub4)...'
None of this is working. I cannot seem to get out the results that do
NOT contain any of those strings.
Appreciate any pointers!
Thanks!
