Can someone help me fine tune this query, It is taking too long so I must be doing something wrong.


select
      contact1.company,
      contact1.contact,
      contsupp.address2 as EM_Contact,
      contsupp.contsupref,
      contsupp.zip
      from contsupp join contact1
      on contact1.accountno=contsupp.accountno and
      contsupp.contact = 'E-mail Address'
      where
      contact1.accountno in
      (select * from
      contact1,
      conthist,
      contact2,
      contsupp
      where contact1.accountno=conthist.accountno and
      contact1.accountno = contact2.accountno and
      conthist.ref like
      '%Seminar Approaching%' and
      contact2.umarket = 'New York' or contact2.umarket = 'New Jersey')

Try this:

SELECT c1.company, c1.contact, cs.address2 as EM_Contact, cs.contsupref, cs.zip
FROM contsupp cs
 JOIN contact1 c1 ON c1.accountno = cs.accountno
 JOIN contact2 c2 ON c1.accountno = c2.accountno
 JOIN conthist ch ON c1.accountno=ch.accountno
WHERE cs.contact = 'E-mail Address'
 AND ch.ref like '%Seminar Approaching%'
 AND c2.umarket IN ('New York','New Jersey')

Indexes on contsupp(contact) and on contact2(umarket) will help performance, as well as on all accountno columns, if these don't already have indexes.

Ah, add the "Distinct" keyword:

SELECT Distinct c1.company, c1.contact, cs.address2 as EM_Contact, cs.contsupref, cs.zip
FROM contsupp cs
 JOIN contact1 c1 ON c1.accountno = cs.accountno
 JOIN contact2 c2 ON c1.accountno = c2.accountno
 JOIN conthist ch ON c1.accountno=ch.accountno
WHERE cs.contact = 'E-mail Address'
 AND ch.ref like '%Seminar Approaching%'
 AND c2.umarket IN ('New York','New Jersey')
