dbplus_tcl — Execute TCL code on server side

说明

dbplus_tcl ( int $sid , string $script ) : string

A db++ server will prepare a TCL interpreter for each client connection. This interpreter will enable the server to execute TCL code provided by the client as a sort of stored procedures to improve the performance of database operations by avoiding client/server data transfers and context switches.

dbplus_tcl() needs to pass the client connection id the TCL script code should be executed by. dbplus_resolve() will provide this connection id. The function will return whatever the TCL code returns or a TCL error message if the TCL code fails.
