Ok I got it: I forgot to call PDOStatement->execute() after the calls to
bindParam() to bind php variables to query parameters. My fault !

Still the problem is I could not use Large Object data type in ODBC to
insert values
in my BIT VARYING column. It said the parameter is of type lo, which I
created as in
the how-to, but the columns is BIT VARYING. Using CAST() on the
parameter did not
help. :(
