Select if exists in column

Anonymous — Mon, 20 Jun 2011 09:05:17 GMT

Hi - thanks in advance for any replies.

I have a table which has the following fields:

File No

Owner

Worked on By

I need to create a report with a dimension of Worked on By and count(File No) - this works fine

However I also need the ffollowing which is proving more difficult:

If Worked on By is in (Select distinct Owner) - flag as '1', otherwise flag as '0'

I need to have the table with Worked on By and count(File No) with an additional column, and the value in this column depends if they are an Owner or not.

So something like if they exist in the Owner column flag as '1'

Hope this makes sense, thanks again

Hi,

Please can you post the sample QV document? It will be easy to try with some data...

Thanks - DV

Sorry I don't have a sample document but here's some of the code:

TimeRecording:

LOAD id as [TR ID],

caseno as [TR Case No],

daterecorded as [TR Date],

actiontype as [TR Action Type],

owner as [Owner],

handler as [Worked on By],;

SQL SELECT *

FROM table

WHERE daterecorded >= '2010-11-01'

AND caseno in (SELECT caseno FROM table2);

Many Thanks

Your code should be as follows.

Table2:

Load * ;

SELECT caseno FROM table2;

LOAD id as [TR ID],

caseno as [TR Case No],

daterecorded as [TR Date],

actiontype as [TR Action Type],

owner as [Owner],

handler as [Worked on By] Where exists(caseno,caseno ) and daterecorded >= Date(Date#('2010-11-01','YYYY-MM-DD)','YYYY-MM-DD'); //Make sure that Daterecorded date formate matches with 'YYYY-MM-DD'

SQL SELECT * FROM table;

Drop Table Table2;

Thanks for your reply, I may not have described the issue

This statement works fine.

TimeRecording:

LOAD id as [TR ID],

caseno as [TR Case No],

daterecorded as [TR Date],

actiontype as [TR Action Type],

owner as [Owner],

handler as [Worked on By];

SQL SELECT *

FROM table;

However I also need something like

handlertype as Owner if the value in handler exists somewhere in owner field (not just the same row)

otherwise handlertype as Assistant

Hope that makes it clearer, thanks again

Same Exists would do the job for you.

LOAD IF(Exists(owner,handler) or owner = handler, 'Owner ','Assistant' ) as handlertype,

id as [TR ID],

caseno as [TR Case No],

daterecorded as [TR Date],

actiontype as [TR Action Type],

owner as [Owner],

handler as [Worked on By];

SQL SELECT *

FROM table;

I have create dummy working application. Have a look at the attched application.

Hope this helps you.
