A definition query can be used to limit which records are visible in the Reviewer table. For example, you might add a Geodatabase layer containing cities around the world but only want the map to show cities with a population over 1 million. ; Choose a language on the Parser menu. If you use a wildcard character in a string with the = operator, the character is treated as part of the string, not as a wildcard. When using outSR with pbf, the pbf format will use coordinate quantization for layer queries. for one character. Operator Description {} Access an item in a list by its zero-based numeric index. Using this as a starting point, you can refine the clause as necessary from there. The purpose of the Query Attributes check is to identify errors based on a Structured Query Language (SQL) query that can include one or more attribute values.

It can be used with strings (comparison is based on alphabetical order), numbers, and dates. New at 10.3. You do not have to manually create definition queries for all feature layers and apply new queries to additional feature layers in different maps or charts. Structured Query Language (SQL) is a standard computer language for accessing and managing databases. Operator Description [] Access the fields of a record by name. Thus, the text string typed into the Query Attributes task of the web application at runtime must match the case of the actual attribute value being matched.
