For applications, FedSQL provides a common SQL syntax across all data sources. That is, FedSQL is a vendor-neutral SQL dialect that accesses data from various data sources without having to submit queries in the SQL dialect that is specific to the data source. In addition, a single FedSQL query can target data in several data sources and return a
single result set.
You can submit FedSQL statements to the CAS server from a SAS or SAS Viya session by using the FEDSQL procedure. For more information about the FEDSQL procedure, see Base SAS Procedures Guide. You can also submit FedSQL statements to the CAS server in SAS Viya by using the fedSql.execDirect action. For more information about the fedSql.execDirect action, see SAS Viya: System Programming Guide. 
When FedSQL statements are executed by the CAS server, the FedSQL result set isalways an in-memory CAS table. You can use other CAS actions to persist the result seton the CAS server or to save the result set to an external data source.
