Description
int mysql_errno
([int
link_identifier])
Returns the error number from the last mySQL function, or
0 (zero) if no error occurred.
Errors coming back from the mySQL database backend no longer
issue warnings. Instead, use mysql_errno() to
retrieve the error code. Note that this function only returns the
error code from the most recently executed mySQL function (not
including mysql_error() and
mysql_errno()), so if you want to use it,
make sure you check the value before calling another mySQL
function.
