# pg_query

(PHP 4 >= 4.2.0, PHP 5)

pg_query -- Execute a query

## Leírás

resource pg_query ( string query )
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().

> Megjegyzés: 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.

> Megjegyzés: 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.
