<A

PostgreSQL and get the result one by one using
<A
HREF="function.pg-get-result.html"
><B
CLASS="function"

>. Script execution is not blocked
while query is executing. Use
<A
HREF="function.pg-connection-busy.html"
><B
CLASS="function"
>pg_connection_busy()</B
></A
> to check connection is
busy (i.e. query is executing). Query may be canceled by calling
<A
HREF="function.pg-cancel-query.html"
><B
CLASS="function"
>pg_cancel_query()</B
></A
>.
</P
><P
> Although user can send multiple query at once, user cannot send
multiple query over busy connection. If query is sent while
connection is busy, it waits until last query is finished and
discards all result.
