Determines how and when schema files are generated.

Possible Values

Data Type

string

Default Value

"Never"

Remarks

The driver can generate schema files corresponding to views returned by the driver. Editing these generated schema files gives you granular control over the metadata (such as columns) returned by the driver when the corresponding views are queried.

For example, removing a column (<attr> element) from a generated schema file causes that column not to be reported.

Schema files generated by the driver are output to the folder specified in the Location connection property.

When this connection property is set to OnUse, upon making a metadata request for a view, the driver generates a schema file for that view.

When this connection property is set to OnStart, the driver generates schema files for all the views that are discovered when the connection begins.

Schema files are not overwritten if they already exist in the Location folder. To update a specific schema file with updated metadata, first delete that schema file from this folder, then trigger the schema file creation again.
