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
