OGR Virtual Dataset (VRT) Parameters
Dataset
Source VRT File(s)
The path to the VRT source file.
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.
Encoding
Character Encoding
Specifies the character encoding mechanism of the underlying data source. If not specified, the reader assumes the encoding mechanism of the current system.
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.
