pg_exec
Description
resource pg_exec ( resource connection, string query)pg_exec() returns a query result resource if query could be executed. It returns FALSE on failure or if connection is not a valid connection. Details about the error can be retrieved using the pg_errormessage() function if connection is valid. pg_errormessage() sends an SQL statement to the PostgreSQL database specified by the connection resource. The connection must be a valid connection that was returned by pg_connect() or pg_pconnect(). The return value of this function is an query result resource to be used to access the results from other PostgreSQL functions such as pg_fetch_array().
Poznßmka: connection is a optional parameter for pg_exec(). If connection is not used, default connection is used. Default connection is the last connection made by pg_connect() or pg_pconnect().
Although connection can be omitted, it is not recommended, since it could be a cause of hard to find bug in script.
