you are using aliases in your subquery -- that's good. however, the problem is that you select "opp.actualamount" twice. this is fine for an end result on screen, but not for a view definition. add another alias or two and you are fine ...

Kind regards,
Lex.

Subject: Problem with limitation of result

Hi,

the following query works as a normal query:

SELECT sc.seccodedesc AS ACCOUNTOWNER, oppsc.seccodedesc AS

OPPORTUNITYOWNER, acc.account, ui.username, opp.description AS OFFERNO, 
opp.actualclose,  opp.reason, opp.estimatedclose, opp.status, 
opp.actualamount, sod.project_no, opp.actualamount, sod.project_name,

sod.category, sod.notes, sod.swisslogprob, sod.projectprob, ((sod.swisslogprob * sod.projectprob)/100) AS probability, sod.targetproject, sod.req_for_pro, sod.handover, sod.createdate

FROM opportunity opp, swl_opp_desc sod, seccode sc, seccode oppsc, account acc, userinfo ui

	WHERE										sod.opportunityid = opp.opportunityid
	AND opp.seccodeid = oppsc.seccodeid
	AND acc.accountid = opp.accountid
	AND acc.seccodeid = sc.seccodeid
	AND ui.userid = opp.ACCOUNTMANAGERID

but doesn't work as a subquery or a view. i should have this as a subquery, because i want to limit the result using ROWNUM. so i've made the following:

SELECT ROWNUM, oppview.* FROM

(SELECT sc.seccodedesc AS ACCOUNTOWNER, oppsc.seccodedesc AS

OPPORTUNITYOWNER, acc.account, ui.username, opp.description AS OFFERNO, 
opp.actualclose,  opp.reason, opp.estimatedclose, opp.status, 
opp.actualamount, sod.project_no, opp.actualamount, sod.project_name,

sod.category, sod.notes, sod.swisslogprob, sod.projectprob, ((sod.swisslogprob * sod.projectprob)/100) AS probability, sod.targetproject, sod.req_for_pro, sod.handover, sod.createdate

FROM opportunity opp, swl_opp_desc sod, seccode sc, seccode oppsc, account acc, userinfo ui

	WHERE										sod.opportunityid = opp.opportunityid
	AND opp.seccodeid = oppsc.seccodeid
	AND	acc.accountid = opp.accountid
	AND acc.seccodeid = sc.seccodeid
	AND ui.userid = opp.ACCOUNTMANAGERID) oppview

WHERE ROWNUM BETWEEN 0 AND 10 then i get "ORA-00918: column ambiguously defined".

would be great if somebody could explain me what causes that error and how to do that the right way.

thanks
beni
