I have a court program with related tables
citation
citkey varchar(16) NOT NULL PRIMARY KEY, ....
cdefendant citkey varchar(16) NOT NULL PRIMARY KEY references citation, ....
ccourt
citkey varchar(16) NOT NULL PRIMARY KEY references citation, ....
disposition
citkey varchar(16) NOT NULL PRIMARY KEY references citation, ....
ccontinue
citkey varchar(16) NOT NULL references citation, ....
warrant
citkey varchar(16) NOT NULL references citation,
....
I am trying to extract data related to the last conttinue date using
select c.citkey, /* c.cdate, c.badge, c.vioDesc, b.lname, b.fname, b.mi, b.race, b.dob, b.sex,
d.docket, d.plea, d.fine, d.costs, d.ddate, d.abdocket, d.bond,
p.disDate, p.disDesc, p.disCode, p.amount,
*/
t.contDate,
t.abcontinue,
w.bndType, w.bndAmt from citation c, cdefendant b, ccourt d, ccontinue t, disposition p, warrant w where c.citkey = b.citkey and b.citkey = d.citkey and d.citkey = t.citkey and t.citkey = p.citkey and
p.citkey = w.citkey group by c.citkey, c.cdate, c.badge, c.vioDesc, b.lname, b.fname, b.mi, b.race, b.dob, b.sex,
d.docket, d.plea, d.fine, d.costs, d.ddate, d.abdocket, d.bond,
p.disDate, p.disDesc, p.disCode, p.amount,
t.abcontinue, t.contDate,
w.bndType, w.bndAmt
having max(t.contDate) = t.contDate
order by c.citkey
I cannot seem to get unique rows with only the max contDate??
i.e.
citkey | contdate | abcontinue | bndtype | bndamt ------------+-------------+------------+---------+---------
991164031 | 06/07/2000 | 6 | Bond | 0.00
991164031 | 07/19/2000 | 6 | Bond | 0.00
thanks
