Get Count (Data Management)


Returns the total number of rows for a table.


  • If the input is a layer or table view containing a selected set of records, only the selected records will be counted.

  • This tool honors the Extent environment. Only those features that are within or intersect the Extent environment setting will be counted.

  • You can view the returned row count in Geoprocessing history.

  • In ModelBuilder, Get Count can be used to set up a precondition, as illustrated below. In this model, Get Count counts the number of records returned by the Select tool. If the count is zero, Buffer will not run due to the precondition.
