fbsql_errno --  Returns the numerical value of the error message from previous FrontBase operation


int fbsql_errno (resource [link_identifier])

Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.

Errors coming back from the fbsql database backend dont issue warnings. Instead, use fbsql_errno() 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() and fbsql_errno()), so if you want to use it, make sure you check the value before calling another fbsql function.

echo fbsql_errno().": ".fbsql_error()."<BR>";
echo fbsql_errno().": ".fbsql_error()."<BR>";
$conn = fbsql_query("SELECT * FROM nonexistenttable;");
echo fbsql_errno().": ".fbsql_error()."<BR>";
