Create a database with three tables: temperature, humidity, pressure. Use the following code:
CREATE TABLE `fasensor7`.`temperature` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `temperature` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ; CREATE TABLE `fasensor7`.`pressure` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `pressure` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ; CREATE TABLE `fasensor7`.`humidity` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `temperature` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ; CREATE TABLE `fasensor7`.`light` ( `id` INT( 255 ) NOT NULL AUTO_INCREMENT , `timestamp` VARCHAR( 255 ) NOT NULL , `pressure` VARCHAR( 255 ) NOT NULL , PRIMARY KEY ( `id` ) ) ENGINE = MYISAM ;
