If Selection Exists (ModelBuilder)

Summary

Checks whether the input data includes a selection and whether a certain number of records are selected.

Learn how If Selection Exists works in ModelBuilder

Usage

• Use this tool to check whether the input data includes a selection or to identify the number of selected records.

• This tool does not make a selection. It checks whether the number of selected records matches a specified value. Use the Select Layer By Attribute tool to make a selection in ModelBuilder. Use the If Field Value Is tool to check whether the input dataset includes records that match an SQL expression or where clause.

• This tool is only available from the ModelBuilder ribbon for use in models. The tool is not available from the Geoprocessing pane or from Python.

• The tool has two Boolean outputs, True and False. Based on the condition being evaluated, one of the two Boolean outputs is true and the other is false after the tool runs. These Boolean outputs must be set as a precondition to the downstream tools for those to execute if either of the preconditions is true.
