The main reason why the error has been generated is because there is already an existing value of 1 for the column ID in which you define it as PRIMARY KEY (values are unique) in the table you are inserting.
Why not set the column ID as AUTO_INCREMENT?
CREATE TABLE IF NOT EXISTS `PROGETTO`.`UFFICIO-INFORMAZIONI` (
`ID` INT(11) NOT NULL AUTO_INCREMENT,
`viale` VARCHAR(45) NULL ,
.....
and when you are inserting record, you can now skip the column ID
INSERT INTO `PROGETTO`.`UFFICIO-INFORMAZIONI` (`viale`, `num_civico`, ...)
VALUES ('Viale Cogel ', '120', ...)Copyright © 2021 Codeinu
