Union Of two Queries in Cognos Report studio

[santosh.yelugoi]

Hi All,

Good Morning All!!!!!!

I have a report where i want to merge two query results in to single query.
For this I have used Union but when i tried to run the report I am getting below error message:

RQP-DEF-0182
The queries for the set operation are in compatible.

So I request you to provid ethe solution to overcome this issue.

Regards,
Santosh :'(

1. same number of items for each query that takes part in the union
2. item for item datatype should be the same between the 2 queries

Hi,

I have already followed below rules for Union:

1. Same number of columns
2. Same Order
3. Same Data types

After following above rules I am getting same error as:

RQP-DEF-0182
The Queries for the set operation are incompatible.

I would check each individual query to find out about the dataitems projected and analyze the datatypes. Report Studio does not report back on the datatypes. Somewhere the 3 rules you mention are not obeyed..
