NAME="data-source-name": specifies a new name for the data source. When you change the name, you create a logical representation of the physical data source. You are not duplicating any physical data.

REQUIRED_DATASOURCE=YES | NO: specifies whether the data source is added to the list of required data sources for the information map. By default, the data source and its assigned filters are included in a query only when a data item that references the data source is explicitly selected for the query. Specify YES if you want the data source and any associated assigned filters to be used in every query that is generated from the information map.

Default:NO

Note:After the data source is updated, you can use the REQUIRED_DATASOURCES= option in the UPDATE CURRENT_MAP or UPDATE INFOMAP statements to control whether it is required.

Example

update datasource "Customer" 
       name="Customer_US" 
       description="Customers from the US"
       required_datasource=no;
