Hi Community.
I have two simple resident tables. Lets say Temp1 and Temp2...
Temp1:
Load * Inline [
A|B
1|abc
2|abc
3|abc
3|abc
3|abc
] (delimiter is '|');
Temp2:
Load * Inline [
A|C
1|xyz
2|xyz
4|xyz
] (delimiter is '|');
In final result table Tab2 I want to get only those records from resident table Temp2 that don't exist in the other resident table Temp1. The result should be obviously record 4|xyz...I use following code...
Tab1:
NoConcatenate Load * Resident Temp1;
Drop Table Temp1;
Tab2:
NoConcatenate Load * Resident Temp2 Where not Exists(A);
Drop Tables Temp2, Tab1;
The result is table Tab2 with no records...
Please, any hints where the problem is?

Hi Sunny,
Thank you for your idea. It's clear and simple, but it is not the right solution for my issue. I cannot use the WHERE clause while loading data into Temp2 table. In real app/model the situation is not that easy. I concatenate/join the information in Temp1 and Temp2 from several other tables using different conditions.
I have to read data/compare data from/between these two resident Temp tables!
Nevertheless, after deeper study of help.click.com I found the right solution...
Here it is...
Temp1:
Load * Inline [
A|B
1|abc
2|abc
3|abc
3|abc
3|abc
] (delimiter is '|');
Temp2:
Load * Inline [
C|D
1|xyz
2|xyz
4|xyz
] (delimiter is '|');
Result:
Load
C as A,
D
Resident Temp2 Where not Exists(A,C);
Drop Tables Temp1, Temp2;
Try this when you load the Temp2 table because once you do the resident load.... 4 is now available from Temp2
Temp1:
Load * Inline [
A|B
1|abc
2|abc
3|abc
3|abc
3|abc
] (delimiter is '|');
Temp2:
Load * Inline [
A|C
1|xyz
2|xyz
4|xyz
] (delimiter is '|')
Where not Exists(A);
