If Selection Exists (ModelBuilder)—ArcGIS Pro

Summary

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

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.

Label	Explanation	Data Type
Layer Name or Table View	The input layer or table view to check.	Table View; Raster Layer; Mosaic Layer
Selection Condition (Optional)	Specifies the selection condition that will be used. Exists—Checks whether any of the input's records are selected. This is the default. No Selection—Checks whether none of the input's records are selected. All Selected—Checks whether all of the input's records are selected. Is Equal to—Checks whether the number of the input's selected records is equal to the Count parameter value. Is Between—Checks whether the number of the input's selected records is between the Minimum Count parameter value and Maximum Count parameter value. Is Less Than—Checks whether the number of the input's selected records is less than the Count parameter value. Is Greater Than—Checks whether the number of the input's selected records is greater than the Count parameter value. Is Not Equal to—Checks whether the number of the input's selected records is not equal to the Count parameter value.	String
Count (Optional)	The integer count value.	Long
