Problem in adding rowwise...!

2003-08-26 23:39

Hi...

I want to add all the fields in my report that are ROWWISE...how can i do it?

But in the "VALUES FORM" in "RESET TYPE" i find only "COLUMN"...that's 'am able to add only Columnwise...'n not rowwise...

If i specify the reset type as column, 'am getting error!

Plzz help me in this regard..!

 

thanx a lot..

Anuradha.

You have two options here. You can sum selected columns in each row in your SQL query like this:

 

SELECT columnA, columnB, (columnA + columnB) as columnC FROM tablename

 

Another alternative is to use a report variable to sum fields in each row. The variable expression to sum two Double fields would look something like this:

 

<variableExpression>new Double((($V{columnA}.doubleValue()) + ($V{columnB}.doubleValue()))</variableExpression>

 

To avoid errors you should test for null values like this:

 

<variableExpression>new Double((($V{columnA} != null)?$V{columnA}.doubleValue():0) + (($V{columnB}!=null)?$V{columnB}.doubleValue():0))</variableExpression>

 

The calculation type for this variable should be "Nothing".

 

Hope this helps.
