====== Attribute query ====== An attribute query is an interrogation of the attribute table of a layer, on one or more fields for selecting entities with common properties (attributes). Such a request requires the use of logical operators (AND, OR, NOT) and / or comparison operators (equal, not equal, greater than, less than, or greater, or less). \\ See: [[english:glossary:RDBMS|Relational Database Management System (RDBMS)]] \\ [[glossaire:requete_attributaire|[French: RequĂȘte attributaire]]]
