No this retrieves the health and the score from a database, if you want to save/update something then use INSERT syntax to store something or use UPDATE syntax to update a stored data.
Examples of INSERT and UPDATE syntaxes:
executeSQLQuery("INSERT INTO players(name,color,sound) VALUES(?,?,?)", playerName, colorName, soundName )
executeSQLQuery("INSERT INTO `players`(`name`,`color`,`sound`) VALUES(?,?,?)", playerName, colorName, soundName )
executeSQLQuery("UPDATE players SET color='green',sound='somehead' WHERE name=?", playerName )
executeSQLQuery("UPDATE players SET color=?,sound=? WHERE name=?", colorName, soundName, playerName )
executeSQLQuery("UPDATE `players` SET `color`=?,`sound`=? WHERE `name`=?", colorName, soundName, playerName
