Question

INNER JOINS

Asked by: jwilliams1

I am trying to create a SQL statement where I can retrieve data and place them into list boxes.

The two statements I want to combine are :

select distinct theme_id, theme_desc from smc_theme order by theme_desc

select extent_id, extent_desc from smc_extent where extent_id in (select extent_id from smc_theme_extent where theme_id = " & th & ") order by extent_desc

Your help is need urgently. Thanks in advance.

If you want to combine the results from these two queries use union:

select distinct theme_id, theme_desc from smc_theme
union
select extent_id, extent_desc from smc_extent where extent_id in (select extent_id from smc_theme_extent where theme_id = " & th & ")
order by theme_desc

Notice only one order clause can be used and the columntypes from part 1 and part 2 must be the same.

Good luck!

Comments about jjokocha,
.....u can not use order by {columnname} for union commands.

u have to use order by 2 for this (the column  number in Select commands)

select distinct theme_id, theme_desc from smc_theme
union
select extent_id, extent_desc from smc_extent where extent_id in
(select extent_id
from smc_theme_extent
where theme_id = "&th&")
order by 2

Are you trying to get one records set for one list box, that contains data from both tables, or are you trying to build two separate list boxes, where the data in the second depends on the record chosen in the first?

Which tool are you using?

build two separate list boxes, where the data in the second depends on the record chosen in the first?

 

by: markgeerPosted on 2000-09-25 at 06:00:46ID: 4429573

OK, I understand you want two separate list boxes - that should be possible.  Now, which tool are you working in: Oracle Forms, Oracle Reports, VB, something else?

 

by: jwilliams1Posted on 2000-10-18 at 08:15:56ID: 4791164

oracle and ASP

 

by: markgeerPosted on 2000-10-18 at 09:44:16ID: 4793079

Building list boxes like that (where the second one is limited by data chosen in the first) is easy in Oracle Forms, but not possible in Oracle Reports.  I don't use VB or ASP so I can't help you there.
