SQL Gateway Connections (Tools/APIs)
Manage and access SQL Gateway connections programmatically (check connections, query by name, and so on).
The SQL Gateway allows InterSystems IRIS® to access external databases via both JDBC and ODBC. For a detailed description of the SQL Gateway, see Using the InterSystems SQL Gateway.
An SQL Gateway connection contains information about accessing a specific external database via JDBC or via ODBC. You generally define these connections in the Management Portal.
The special variable $SYSTEM is bound to the %SYSTEM package. This means that instead of ##class(%SYSTEM.class).method(), you can use $SYSTEM.class.method().
