Defining an SQL query in ArcGIS Production Mapping

Доступно с лицензией Production Mapping.

Structured Query Language (SQL) queries allow you to select features by using feature attributes. When you choose the feature attributes you want to use in the query, you can then specify a range of values to use to define a selection set for a tool. In ArcGIS Production Mapping, SQL queries can be used with ArcGIS Data Reviewer Desktop to define a set of features to use with a particular tool. With Data Reviewer, you can use an SQL query to create a subset of features from a feature class on which you want to run a check. For example, if you want to run a check only on roads that are classified as major highways, you could define a query that selects only those features for the check.

For more information about data checks in Data Reviewer, see Checks in Data Reviewer.

You can also use this tool to select features from the first layer listed in the table of contents.
