PI SQL Subsystem (pisqlss) prepares and executes SQL statements to be run by Data Archive. The primary users of this subsystem are the PI ODBC driver and the PI SDK. This driver conforms to the ODBC API standards and makes PI data appear to be organized into data tables. PIODBC1.1.2 or later is required to connect to Data Archive.
AVEVA's implementation of SQL gives applications access to the PI Point Database, snapshot, and archive. For supporting information, such as details of AVEVA's implementation of SQL, see the PI ODBC Client User Manual.
