Question

I need to Update the MySQL DB from Java. In particular, I need to update the time field called as ´t_field´.

CREATE TABLE IF NOT EXISTS `TimeTest` (
  `id` SMALLINT NOT NULL AUTO_INCREMENT,
  `t_field` TIME NOT NULL,
  `resQty` INT(3)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

How can I use the symbol " in the String to write the UPDATE statement if JAVA?

String query = "UPDATE TimeTest SET t_field = "00:05" WHERE id=1"; // sure, it does not work

Answer 1

use single quotation

String query = "UPDATE TimeTest SET t_field = '00:05' WHERE id=1";

or

String query = "UPDATE TimeTest SET t_field = \"00:05\" WHERE id=1";
