Database Connection
Database
This is the data source name. When you enter the Database in the Source Dataset field, the Database field will be automatically populated in the Settings box.
Constraints
Table List
After you have completely 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 Reader Parameters box.
WHERE Clause
Enter any SQL where clause that constrains the attributes of the layers selected in the layer list (for example, NUMLANES=2).
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.
