Database Connections
|
Database formats include a Database Connection parameter that defines and stores authentication information. For general information about sharing database connections, please see Using Database Connections. Note that Database Connection parameters may differ slightly, depending on context and/or database format. |
Connection
Select an existing connection, or Add Database Connection to define a new connection.
The new connection can be made visible only to the current user, or can be shared among multiple users.
Connection Parameters
Host
Contains the name or IP address of the machine that is running the MySQL database. If the database resides on the local machine then this parameter should be set to localhost or the name or IP address of the local machine.
Port
When connecting remotely, this specifies the TCP/IP port on which to connect to the DBMS service. The default port is 3306.
Database
This field is populated with the Dataset containing the name of the database.
Username and Password
Enter the username and password to access the service.
Constraints
Table List
Enter (or browse for) the name(s) of specific database table(s) to import.
Schema Attributes
Additional Attributes to Expose
Use this parameter to expose Format Attributes in Workbench when you create a workspace:
- In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
- In a non-dynamic scenario, you can use this parameter to expose additional attributes on multiple feature types.
Advanced
Fetch All Features At Once
If Yes, the entire result set of the main feature query is retrieved into a large buffer in client memory. If No, the reader retrieves one row at a time from the server, caching them in a smaller buffer and consuming less memory. A value of No allows for large datasets to be processed without the possibility of running out of client memory. A value of Yes may improve the performance of smaller queries.
