How to display '0' where no data found in PL/SQL Oracle Reports I have an Oracle Report (11g) in which I have selected a number field containing amount and have mentioned the format mask as 999,999,999,999. The data is displayed as follows.


Data1            25,000
Data2           
Data3            23,000


Now I want to show a simple '0'in front of an empty record (i.e. Data2). I've tried it in adding a Formula Column (PL/SQL), or by initializing a '0' in the property palate of field by defining '0' against "Value if null". But, it doesn't work. 

However, when I remove the format mask, value '0' is displayed by both above mentioned ways (by adding a formula column or by defining the value against 'value if null'). But, by doing this, the amount is displayed without format mask (i.e. 25000 and 23000).

How can I achieve the above discussed scenario. I want that the format mask should be there, and there should b '0' in front of empty records as well. In short, I need the following output in Oracle Reports 11g - 64 bit. 


Data1            25,000
Data2                 0
Data3            23,000
The format mask needs to be changed to 999,999,999,990.  The 9 format suppresses the value if it is a leading zero, whereas 0 prints it.
