Conditional Block

[cognoid1]

I want to display "No Data Available" when the query doesn't return any rows and display a crosstab with result if there is data returned from the query.

At the moment, I get a "blank" crosstab if there is no data and it is not intuitive enough for our end users.  I know conditional Block would solve this problem, but how do I detect no data return?

If (data is not null)
   display CROSSTAB
else
   display ("No data available")


Please advise.

Thank you.

Hi,

Try with this one...

if(running_total=0)

then Dispaly( ' No data Return ' )

else Display Cross Tab

U can do this by using Conditional Block..

Hope It Will work...

     Try with this..create a conditional variable with rownumber()>0

If true then show the cross tab else Hide..


Thanks,

In this example they use a parameter, for the expression in the variable, which is populated from a prompt. I still haven't found an example that uses a query item for the expression in the variable, well an example that works anyway.

HI JUST DO THIS

TAKE A CALCULATION COLUMN AND PUT 1 IN IT JUST THE NUMBER 1 AND NAME IT AS CONDITION
THEN GOTO VARIABLES SECTION AND WRITE CONDITION = 1
USE A BOOLEAN VARIABLE.
THEN CLICK ON LIST FOOTER CHECK BOX AND INSERT A TEXT BOX IN THERE
AFTER ACCESING THE VARIABLES SECTION AGAIN TO DISPLAY NO DATA JUST SELECT HIDE BOX PROPERTY

HOPE IT SOLVES YOUR PROBLEM

Cognoid,
Will you give us an update on this?  Has the issue been resolved.  If so, How did you do it?

I didn't have any luck with this, therefore, I gave up the idea.

I'm sorry.
