Value is similar to COALESCE which is used in a Sql query .Value returns the first aurgument which is not null

U can get more information in the following link

Hi Vijay,

It is corect the verb value replace null value with specified values
I.g

Null value in coloumn envir_nmwill replaced by space &
Null value in e2.ent_id replaced by 0
