Dear all,
I have a Local zone , where users feel that performance is not good.
Is it wise to collect the inputs from the local zone rather than taking from the global zone.
And also Can I tune from Global zone , so that it will reflect in local zone.

fbsql_errno
FBSQL_ERRNO(3) 1 FBSQL_ERRNO(3)fbsql_errno - Returns the error number from previous operationSYNOPSIS
int fbsql_errno ([resource $link_identifier])
DESCRIPTION
Returns the numerical value of the error message from previous FrontBase operation.
Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_errno(3) to retrieve the error code. Note that
this function only returns the error code from the most recently executed fbsql function (not including fbsql_error(3) and fbsql_errno(3)),
so if you want to use it, make sure you check the value before calling another fbsql function.
PARAMETERS
o $
link_identifier -A FrontBase link identifier returned by fbsql_connect(3) or fbsql_pconnect(3).If optional and not specified, the
function will try to find an open link to the FrontBase server and if no such link is found it will try to create one as if
fbsql_connect(3) was called with no arguments.
RETURN VALUES
Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.
EXAMPLES
Example #1
fbsql_errno(3) Example
<?php
fbsql_connect("marliesle");
echo fbsql_errno() . ": " . fbsql_error() . "<br />";
fbsql_select_db("nonexistentdb");
echo fbsql_errno() . ": " . fbsql_error() . "<br />";
$conn = fbsql_query("SELECT * FROM nonexistenttable;");
echo fbsql_errno() . ": " . fbsql_error() . "<br />";
?>
