nested query

Postby pplastiras » 02. July 2011 08:42

hi, i have a problem with a nested query i'm trying to create. the query code is:

Code: Select all
SELECT pc.pc_id, pc.pc_no, pc.pc_net, pc.pc_loc, pc.pc_name,
sw.swtch_id, sw.swtch_model, sw.swtch_rack, sw.swtch_loc,
conn.swtchconn_swtchid, conn.swtchconn_pcid, conn.swtchconn_portno
FROM pcs AS pc, switches AS sw, swtchconn AS con,
WHERE
con.swtchconn_pcid IN (SELECT pc_id, pc_no FROM pcs WHERE pc_id='11' || pc_loc='0' || pc_net='0' HAVING pc_no!=1) &&
con.swtchconn_swtchid IN (SELECT swtch_id, swtch_no FROM switches WHERE swtch_id='0' || swtch_rack='2' || swtch_loc='0' HAVING swtch_no!=1)


and the error message i get back is:

Error Code : 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE

con.swtchconn_pcid IN (SELECT pc_id, pc_no FROM pcs WHERE pc_id='11' || ' at line 9


I have read that maybe the falt is the mysql version but i think i'm working on mysql 5.1 so nasted queries are supported. can anyone help me!!!!!

The readme_en.txt file in the xampp folder will give you some certainty about which version of MySQL you are working with.

Yes my mysql is 5.1, so nested queries must be supported. have you got an idea about what is going wrong?
