There are only two differences between this function and
|
|
<span class="function"><a href="ingres_connect.html" class="function">ingres_connect()</a></span>: First, when connecting, the
|
|
function will initially try to find a (persistent) link that is
|
|
already opened with the same parameters. If one is found, an
|
|
identifier for it will be returned instead of opening a new
|
|
connection. Second, the connection to the Ingres server will not
|
|
be closed when the execution of the script ends. Instead, the
|
|
link will remain open for future use
|
|
(<span class="function"><a href="ingres_close.html" class="function">ingres_close()</a></span> will not close links
|
|
established by <span class="function"><strong>ingres_pconnect()</strong></span>). This type
|
|
of link is therefore called "persistent".
