passing parameters to multiple statements

[Konstantin Izmailov <pgfizm@xxxxxxxxx>]

I'm planning to use multiple statements via libpq. Before starting coding I'm trying to understand are there any limitations on passing parameters. E.g. would the following work:

  PQexecParams(conn, "BEGIN;INSERT INTO tbl VALUES($1,$2);SELECT lastval();SELECT * INTO AUDIT FROM (SELECT $3, 'tbl action', lastval());COMMIT;", 3, ...);

 

Thank you!
