How does one refer to empty cells in mysql?
Posted: Tue May 31, 2011 6:59 am
I have tried the following variations but non works
if($row['relation'] = "" ){
if($row['relation'] = '' ){
if($row['relation'] = NULL ){
if($row['relation'] IS NULL ){
if(strlen($row['relation']) = 0 ){
So how would one refer to a cell that is empty?
if($row['relation'] = "" ){
if($row['relation'] = '' ){
if($row['relation'] = NULL ){
if($row['relation'] IS NULL ){
if(strlen($row['relation']) = 0 ){
