Mapping variable is the scenario where values change when the session is executed. When it is finished, the value at the end is stored by the Informatica server only to be used when the process restarts. Mapping parameters are the values that remain the same when execution is taking place. Mapping usage and parameters are described by mapping procedures. Before the session begins values are assigned to the parameters.

I am using a mapping variable of date/time data-type and aggregation MAX In Source Qualifier SQL Override i am giving select col1,col2 from tbl where col1>$$dt

(col1 is also date data type)

When i am validating the query it is giving Invalid Query and error was

 [Microsoft][ODBC driver for Oracle][Oracle]ORA-00933 : SQL command not properly ended

I have also done extraction of characters like select col1,col2 from tbl where to_char(col1,'DD-MM-YY')>to_char($$dt,'DD-MM-YY') but still the same same

I am not getting what the error is and the same thing if i am trying for number column the it is validating fine and performing incremental extract also.

Any suggestions regarding the same will be helpful

How do you include you mapping output variables in the workflow without having to use a human task?

Basically I have one row of data that I want to push out and to be included in e.g. the body of the Notification task or as an attachment.

We are not using power center, only the developer tool.
