Question

Error Code: 1406. Data too long for column

CREATE  TABLE `TEST` 
(

  `idTEST` INT NOT NULL ,

  `TESTcol` VARCHAR(45) NULL ,

  PRIMARY KEY (`idTEST`) 
);
         


        

Answer 1

I think that switching off the STRICT mode is not a good option because the app can start losing the data entered by users.

If you receive values for the TESTcol from an app you could add model validation, like in Rails

validates :TESTcol, length: { maximum: 45 }

If you manipulate with values in SQL script you could truncate the string with the SUBSTRING command

INSERT INTO TEST
VALUES
(
    1,
    SUBSTRING('Vikas Kumar Gupta Kratika Shukla Kritika Shukla', 0, 45)
);
