Summary
The Create Database Connection tool creates a file that ArcGIS uses to connect to a database or an enterprise, workgroup, or desktop geodatabase.
Usage
If you enter valid connection information when using the tool dialog box, the tool connects to the database to determine if it contains geodatabase schema. If the schema is found, the tool automatically populates the Schema parameter with the sde schema (for Oracle user schema geodatabases only), the Version Type parameter with the Transactional keyword, and the version parameter with the Default version name.
If you want don't want to save your connection information in the Results window or don't want to store it in the geoprocessing history log files, disable history logging and save the connection file without saving the connection information.
All the parameters in the Geodatabase Connection Properties section of the tool dialog box are ignored when connecting to a database that does not contain a geodatabase.
Syntax
CreateDatabaseConnection_management (out_folder_path, out_name, database_platform, instance, {account_authentication}, {username}, {password}, {save_user_pass}, {database}, {schema}, {version_type}, {version}, {date})| Parameter | Explanation | Data Type |
out_folder_path | The folder path where the database connection file (.sde file) will be stored. | Folder |
out_name | The name of the database connection file. The output file will have the extension .sde. | String |
database_platform | The database management system platform to which you will be connecting. The following are valid options:
| String |
instance | The database server or instance to which you will connect. The value you specify for the database_platform parameter indicates the type of database to which you want to connect. The information you provide for the instance parameter will vary, depending the database platform you specified. See below for further information on what to provide for each database platform.
| String |
account_authentication (Optional) |
| Boolean |
username (Optional) | The database user name to connect with when using Database Authentication. | String |
password (Optional) | The database user password when using Database Authentication. | Encrypted String |
save_user_pass (Optional) |
| Boolean |
database (Optional) | The name of the database to which you will be connecting. This parameter only applies to PostgreSQL and SQL Server platforms. | String |
schema (Optional) | The user schema geodatabase to which you want to connect. This option only applies to Oracle databases that contain at least one user-schema geodatabase. The default value for this parameter is to use the sde schema (master) geodatabase. | String |
version_type (Optional) | The type of version to which you want to connect.
| String |
version (Optional) | The geodatabase transactional version or historical marker to connect to. The default option uses the Default transactional version. | String |
date (Optional) | The value representing the date and time used to connect to the database. For working with archiving enabled data. Dates can be entered in the following formats:
