Date: 06/14/02

Hi,

I working with this query
SELECT * FROM entries LEFT JOIN category ON entries.cat_no REGEXP
\"\\\\.\"+category.id+\"(\\\\.|$)\" LEFT JOIN entgroup ON entries.id = entgroup.eid
LEFT JOIN catgroup ON category.id = catgroup.cid LEFT JOIN mzgroup ON
mzgroup.id = entgroup.gid || catgroup.gid WHERE entries.cat_no REGEXP
\"\\\\.24(\\\\.|$)\";

interessting for me ist only this part

ON entries.cat_no REGEXP \"\\\\.\"+category.id+\"(\\\\.|$)\"

i\'ll get this result from mysql

with the REGEXP i hope to get all categories where id is listed in the
cat_no from the entries table. cat_no should show a thread but the 3\'rd
result isn\'t part of the cat_no so REGEXP don\'t work how i expected
How can i fix this?

thans for help
