> COALESCE function returns the first non-null expression in the list. If all expressions
evaluate to null, then the COALESCE function will return null.
> COALESCE( expr1, expr2, ... expr_n )
> expr1 to expr_n are the expressions to test for non-null values.
> Expressions have to be of the same type.
