If Selection Exists (ModelBuilder)

Summary

Evaluates if the input data has a selection and if a certain number of records are selected.

Learn how If Selection Exists works in ModelBuilder

Usage

  • This tool does not make a selection or evaluate an SQL expression or where clause. It simply checks if a selection set matches a specified value. Use the Select Layer By Attribute tool to make a selection in ModelBuilder. Use the If Field Value Is logical tool to evaluate if the input dataset has records that match a 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.

Parameters

LabelExplanationData Type
Layer Name or Table View

Input layer or table view to evaluate.

Table View; Raster Layer; Mosaic Layer
Selection Condition
(Optional)

Specifies the selection condition that will be used for the field values of the records matching the SQL expression.

  • ExistsChecks whether the field value exists for the records matching the SQL expression. This is the default.
  • No SelectionChecks whether none of the records matching the SQL expression are selected.
  • All SelectedChecks whether all of the records matching the SQL expression are selected.
  • Is Equal toChecks whether the field value of the records matching the SQL expression is equal to the count value.
  • Is BetweenChecks whether the field value of the records matching the SQL expression is between the minimum count value and maximum count value.
  • Is Less ThanChecks whether the field value of the records matching the SQL expression is equal to the count value.
  • Is Greater ThanChecks whether the field value of the records matching the SQL expression is greater than the count value.
  • Is Not Equal toChecks whether the field value of the records matching the SQL expression is not equal to the count value.
