ទិដ្ឋភាពទូទៅ

The condition builder compares a field against a typed value or against another field — a comparison the standard Select By Attributes dialog cannot express without hand-written SQL.

ការប្រើប្រាស់

  • Conditions are added with Add Condition and combined with the And/Or column, so several tests can be chained.
  • Each condition has four parts:
PartExplanation
FieldThe field being tested
OperatorThe comparison to apply
Compare ToWhether the right-hand side is a typed Value or another Compare Field
Value / Compare FieldThe value to compare against, or the field to compare against
  • The Compare To switch is what makes this tool worth using: setting it to Compare Field compares two fields on the same feature — finding rows where a recorded area disagrees with a calculated one, for instance.
  • Available operators: Equals, Not Equals, Greater Than, Greater Or Equal, Less Than, Less Or Equal, Contains, Starts With, Ends With, Is Null, Is Not Null
  • Is Null and Is Not Null take no value. They are the reliable way to find missing data — an equality test against an empty string does not find true nulls.
  • Selection Mode controls how the result combines with any existing selection — a new selection, or added to the current one.
  • Results can be selected in the map or exported. Output offers three destinations:
    • Project default geodatabase
    • Same source location — beside the source data
    • Specify output — a path you browse to
  • Export Selected Features writes a feature class; Export Selected Table writes a table without geometry.
  • Select applies the query without exporting, which is the quick way to confirm the conditions match what you expect before writing anything.
