If a Shape field is added to the field list, the result is a layer; otherwise, it is a table view. The default is Use key fields (USE_KEY_FIELDS in Python). The key fields list lets you choose several columns if the combination of these columns is needed to define unique values. However, if this would result in querying Table2 on an nonindexed field, and reversing the order would result in querying Table1 on an indexed field, the order will be reversed in an attempt to maximize performance. This is the sole query optimization logic at work when you're using file geodatabase data with this tool. If the output result is a layer, it may be persisted to a layer file using the Save To Layer File tool or to a feature class using the Copy Features tool. This information defines how rows are uniquely identified and is used to add a dynamically generated ObjectID column to the data. For example, imagine you have a table of customer data, and you want to find those customers who spent more than $50,000 with you last year and whose business type is restaurant. Feature classes can be joined, but the fields list must contain at most one field of type geometry. For details on the syntax for the Expression parameter, see SQL mode. The layer that is created by the tool is temporary and will not persist after the session ends unless the project is saved or the data is persisted by making a copy using Copy Rows or Copy Features.. The tool allows you to provide a key field option and key fields list. This tool accepts data from an ArcSDE geodatabase, a file geodatabase, a personal geodatabase, or an OLE DB connection. Query layers will only work with enterprise databases. If no key fields have been specified, an ObjectID that uniquely identifies each row in the output table will be generated. The Fields and Key Fields parameters' Add Field button is used only in ModelBuilder. This information defines how rows are uniquely identified and is used to add a dynamically generated ObjectID field to the data. If you add more than one geometry column, the tool will display an error when you click OK and execution will stop. I'm needing this in … This parameter applies only if the layer is branch versioned and refers to geodatabase time (separate from LRS time). You can choose several fields from the key fields list if the combination of these fields is needed to define unique values. The order of the fields in the field list is the order the fields will appear in the output layer or table view. If a Shape column is added to the field list, the result is a layer; otherwise, it is a table view.

The name of the table or tables to be used in the query. The name of the table or tables to be used in the query. This tool creates a new feature layer. If there are no fields chosen in the key fields list, the ADD VIRTUAL_KEY_FIELD option is automatically applied. Arc GIS for Desktop ArcGIS Online. An ObjectID field is an integer field that uniquely identifies rows in the data being used. The query can be used to join several tables or return a subset of columns or rows from the original data in the database. The layer or table view can then access the copy and use the added field as the key field. Later versions of ArcGIS may contain different functionality, as well as different names and locations for menus, commands and geoprocessing tools. The input can be an INFO, dBASE, or geodatabase table, a feature class, table view, or VPF dataset. 3. The query can be used to join several tables or return a subset of fields or rows from the original data in the database. This sample demonstrates how to query related features from a FeatureLayer by using the queryRelatedFeatures() method. Usage. ArcGIS for Server.

The query can be used to join several tables or return a subset of columns or rows from the original data in the database. Because query layers access the database directly using SQL, the data does not have to be part of an enterprise geodatabase, but you can define query layers for enterprise geodatabase tables … However, if this would result in querying Table2 on a nonindexed field, and reversing the order would result in querying Table1 on an indexed field, the order will be reversed in an attempt to maximize performance. The Add Field button allows you to add expected fields so you can complete the Make Query Table dialog box and continue to build your model. Without an ObjectID field, selections will not be supported. 2. Choose a table. This sample demonstrates how to apply a filter to a feature layer using the FeatureLayer.Where property and to further filter the result set using a QueryFilter. You use the query builder to construct queries. The name of the layer or table view that will be created by the tool. Clicking on the map highlight a set of wells near the clicked point. Query layers allow you to access spatial and nonspatial tables and views in databases. All input feature classes or tables must be from the same input workspace. How To: Create a one-to-many join in ArcMap . The order of the fields in the field list indicates the order the fields will appear in the output layer or table view. The Add Field button, which is used only in ModelBuilder, allows you to add expected field(s) so you can complete the dialog and continue to build your model. For example, if Table1 is listed before Table2, Table2 will be joined by getting a row from Table1, then getting matching rows from Table2. The query can be used to join several tables or return a subset of fields or rows from the original data in the database. In 10.0 and later, it represents either a layer or table depending on whether the LayerOrTableId is that of a layer or a table. This sample demonstrates how to use a relationship query to display information from a related table for selected features. Applies an SQL query to a database, and the results are represented in either a layer or table view. Standalone table; The Query widget serves as a query builder during configuration, allowing you to define the query by specifying source data and filters, and displaying fields in query results. For example, if Table1 is listed before Table2, Table2 will be joined by getting a row from Table1, then getting matching rows from Table2.
