Hi,
try this.

select case when ctc is null or ctc='' then '0' else ctc end from salary where name ='XYZ'

Note: Null is a varchar kind of value while 0 is int , that's why its giving error when you are writing
"case when ctc is null then 0 else ctc end"

so use it Like this

"case when ctc is null then '0' else ctc end"

Hope it will help you.. :)

Is your columnName a varchar? or what is the data type of it?

Conversion failed when converting the varchar value 'null' to data type int.

jaideepsinh 12-Jul-13 6:18am

It means you have to convert your varchar value to int using cast method.
