Create Database View (Data Management)

Summary

Creates a view in a database based on an SQL expression.

Usage

• The SQL expression used to define the view is validated by the database when you run the tool. Valid syntax for the view definition is determined by the underlying database. If the syntax is incorrect, an error message is returned.

• Views created in a geodatabase using this tool do not support a forward slash (/) character in the view definition. For example, if you have a column in the create view definition that is based on an expression such as Population1990 / 10, you need to create the view using SQL tools.

• This tool is supported for databases, Open Geospatial Consortium (OGC) GeoPackage files, enterprise geodatabases, mobile geodatabases, and file geodatabases.

• Views created in a geodatabase using this tool are not registered with the geodatabase.

• If a spatial column is included in the view, the geometry storage type of the column must be an SQL data type (such as ST_Geometry or Geometry), not a binary geometry storage type.

• Learn more about constructing a query and see examples of SQL expressions.

import arcpy
arcpy.CreateDatabaseView_management("c:/Connections/city_data.sde","trees","select objectid, owner, parcel from inventory where type = trees")

CreateDatabaseView example 2 (Python window)

Create a database view in a file geodatabase.

import arcpy

CreateDatabaseView example 3 (Python window)

Create a database view in a mobile geodatabase.

import arcpy
arcpy.management.CreateDatabaseView("C:\\mymgdbs\\facilities.geodatabase",
                                    "dog_parks",
                                    "select objectid, park_name, park_address, park_hours from parks where park_type = dog")
