pg_query
(PHP 4 >= 4.2.0)
pg_query -- Execute a query
Description
resource pg_query ( resource connection, string query)
pg_query() 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_last_error() function if connection
is valid. pg_query() 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().
Note: connection is an optional parameter for pg_query().
If connection is not set, 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.
Note: This function used to be called pg_exec(). pg_exec()
is still available for compatibility reasons but users are
encouraged to use the newer name.

pg_fetch_object(), pg_num_rows() and pg_affected_rows().
