RE: $ & $$ in Mapping or Parameter File
|
$ - is used to denote Server level Variables/Parameters.
$$ - is used to denote Mapping level Variable/Parameter.
This is the convention that we generally follow to differentiate between Server Level/Mapping Level variables or parameters.
Thus anything related to a server or execution related activities we use $, this means whenever we define any file name or any database name we use a single $ and whenever there is some variable related to mapping or mapplet we use $$ |
