Case Statement help

[KEKeogh]

I'm trying to create the following case statement in Cognos 8.3 but I keep getting an error. 

Could someone point out what may be off?


CASE
WHEN ([DSR].[VIEW_APPLN_AVAIL].[APPLICATION_NAME] contains 'Tide') THEN ((([Total Base]-[Total Outage])/[Total Base])*.35)
else 'Null'
End


I get the following error:  "QE-DEF-0405  Incompatible data types in case statement."

Thanks!

Additional note after some more research:  [APPLICATION_NAME] is a text data item and the THEN part should return a percent.

This MIGHT have worked in ReportNET, but in Cognos 8 BI, all the results returned by a CASE or a IF statement must be of the same datatype. In this case your THEN clause is returning a numeric and your ELSE clause is returning a string 'Null'.

Either try to cast the numeric percentage value of your THEN clause to a string or return a numeric in your ELSE clause.

Thank you!  Thank you!  Thanks you!

;D

That worked perfectly.  I knew it had to be something simple but since I'm new to coding the solution kept eluding me.
