Question

I am using IBM DB2. I have a query which gives the output as:

NAME / AMOUNT

CST / –

VAT / 1400

ST / –

I am trying to write a coalesce function for AMOUNT. The datatype of AMOUNT is decimal(10,2)

COALESCE(AMOUNT,'&nbsp')

The purpose of me doing is, I want a space if the AMOUNT is null, but all I get is an error like “incompatible argument”.

How can I achieve a space? Please help!

Answer 1

The problem is you are saying this…

If amount is not NULL, display a decimal value, but if it is, display a character value instead. Try this

COALESCE(CAST(AMOUNT as VARCHAR(20)),' ')

Should solve your problem
