SELECT col1, col2,col3,col4,col5 FROM tablename

All columns data type are integer

I wrote this following statement, but any of the column has NULL value, I get empty string which is incorrect result.

SELECT (convert(nvarchar(10),col1) + ',' +convert(nvarchar(10),col2)+ ',' +convert(nvarchar(10),col3)+ ',' +convert(nvarchar(10),col4)+ ',' +convert(nvarchar(10),col5)) as colstring FROM tablename


How to concat all columns and make it one string? If any of the column value is NULL, do not include that?
Thanks,
