A Data Source node defines source data for the workflow; for example, a data source node specifies the build data for a model. Any table or view accessible to the user can be selected as the source. This node does not allow any input node connections.
Only certain data types are allowed in a Data Source node; columns with other data types are excluded. See Supported Data Types For Data Source Node for a list of supported data types.
The following topics describe data source nodes:
Data Source nodes rely on database resources for their definition. It may be necessary to refresh a node definition if the database resources change (for example, if the resources are deleted or recreated). See Refresh Data Node, Model Node, or Update Table Node for details.
