hi all,
i'm new to powerbuilder (10) and i have a question.i have made the following query, that does what i want:

gewenste_begindatum = Date(sle_datumaankomst.text)
gewenste_vertrekdatum = Date(sle_datumvertrek.text)

Select "plaats"."plaatsid" INTO :teller
From "plaats"
WHERE "plaats"."plaatsid"
NOT IN (
Select "boeking"."plaatsid"
FROM "boeking"
WHERE (:)gewenste_begindatum > "boeking"."begindatum" AND :gewenste_begindatum < "boeking"."einddatum")
OR :)gewenste_vertrekdatum > "boeking"."begindatum" AND :gewenste_vertrekdatum < "boeking"."einddatum"))
OR :)gewenste_begindatum < "boeking"."begindatum" AND :gewenste_vertrekdatum > "boeking"."einddatum"));

this query works perfectly! it returns the result of a search.
the result of the query should be shown in a listbox which can be done by:
lb_listboxname.additem(string)

but i can't find out how the loop the result of the query.. if that is even possible ??

the 2 sle_name are singleLineEdits :)

is there is an other solution to this problem i'm happy to hear about them! mabye another control or so??

tnx in advance

Hey Gijza!

Powerbuilder relies heavily on it's DataWindow - Technology to work with databases.

My Proposal:

Use an invisible DataWindow called DataStore, give it a DataWindowObject with your Query and access the results of the Query after o_datastore.retrieve() via o_datastore.row[rowindex].col_name.

Was this helpfull?

Bye.
