Database Connection
Connections store authentication information. For general information about sharing database connections, please see Using Database Connections.
Note that different subsets of the Database Connection parameters below are made available in different contexts.
Connection
This parameter specifies a database connection for the reader through a drop-down menu. The Add Database Connection option in the menu allows you to create a new connection. The connection requires a name that describes the connection.
Note: The following characters are not allowed in connection names: ^ \ / : * ? " < > | & = ' + % #
The new connection can be made visible only to the current user, or can be shared among multiple users.
Connection Parameters
Host
The host name of the Denodo Database.
Port
The connection port for the Denodo Database.
Database
The name of the database to connect to.
Username and Password
Enter the username and password to access the database, user account, or wherever authentication is required.
Query Timeout (Seconds)
The time, in seconds, after which to terminate a query to the database if it has not yet returned a result.
If set to 0, there is no timeout. The default is 30.
Note: If this value is not set high enough, then the query will return the error Provider Error - Timeout Expired.
Constraints
Table List
After you have specified the database connection, click the Browse button to select tables for import. A connection window appears while the system compiles a table from the database.
Once the table list appears, you can select one or more tables, and then click OK to dismiss the window. The table name(s) will appear in the Table List field in the parameter box.
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 where you have multiple feature types, it is convenient to expose additional attributes using this one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.
