Function used to retrieve line-column values of an initial catalog to send them in a destination catalog.

You also have the possibility to add columns in your destination column you have not in your initial catalog.

In the example above, we choose to retrieve $code, a, f columns and we insert a new column n.

We take the line one by one and if they respect some selection criteria they will be inserted in the destination catalog. We also insert the n variable which has been compute in a previous node.

The variable which gives the line to insert (a in our example) is an integer variable.
