unpropagate
The unpropagate statement removes repeating data from the currently selected field. If several records in a row contain the same data, this statement erases all but the first (top) value.
Parameters
No parameters.
Description
The unpropagate statement removes repeating data from the currently selected field. If several records in a row contain the same data, this statement erases all but the first (top) value.
This example removes duplicate names from a mailing list. If two records have the same name, this procedure will keep the one that was originally closer to the top of the database. (If you want to keep the one that was closer to the bottom of the database, use the unpropagateup statement.)
field Name
sortup
unpropagate
select Name <> ""
removeunselected
This example first uses sortup to bring all of the duplicate records together. It then uses unpropagate to clear out the duplicate names. Finally, it uses removeunselected to actually remove the duplicate records.
Note: When combined with the fillall statement, the unpropagate statement can modify invisible records as well as visible records. See the FillAll statement for details.
