Contact Us Error message displaying after execution of a query We can display error message in case http://www.plus2net.com/sql_tutorial/mysql_error.php of an error generated by mysql query. This meaning full error message gives idea one the problem or bugs in the script. We can print the error message by using mysql function mysql_error(). This function returns the error message associated with most recently executed query. So it is a good idea to check for error before going to next query. We can even add the error number returned mysql error by mysql to this error message. This way we can generate a meaningful detail on the bugs on the script. MySQL Error MySQL Error No Error Message Error Mail $querry = mysql_query("SELECT new_field FROM student"); echo "Error message = ".mysql_error(); In our student table there is no field as new_field.

'; $row = $pdo->fetch(PDO::FETCH_OBJ); echo "Name : $row->name "; }else{ print_r($pdo->errorInfo()); } In the above code there is an error in sql , there is no column by name no_name. The output will be Array ( [0] => 42S22 [1] => 1054 [2] => Unknown column 'no_name' in 'field list' ) So to get correct result change the sql part like this . $pdo=$dbo->prepare('Select * from student'); With this you will get desired output. Handling PDO errors If such error occurs what is to be done ? We have three options to handle in case of errors. We can stop the execution of the script. ( Fatal error : stop execution of code ) We can display warning message ( Warning only, display message and no stoppage of execution ) Remain silent ( continue
