sql - Error Code: 1406. Data too long for column - MySQL

Error Code: 1406. Data too long for column

CREATE  TABLE `TEST` 
(

  `idTEST` INT NOT NULL ,

  `TESTcol` VARCHAR(45) NULL ,

  PRIMARY KEY (`idTEST`) 
);

Now Insert some values

INSERT INTO TEST
VALUES
(
    1,
    'Vikas'
)

select 

SELECT * FROM TEST;

Inserting record more than the length

INSERT INTO TEST
VALUES
(
    2,
    'Vikas Kumar Gupta Kratika Shukla Kritika Shukla'
)

If we select the length

SELECT LENGTH('Vikas Kumar Gupta Kratika Shukla Kritika Shukla')

 '47'

And it is showing the error message

Error Code: 1406. Data too long for column

But what is my expectation is, I want to insert at least first 45 characters in Table

please let me know if the question is not clear.

I know the cause of this error. I am trying to insert values more than the length of datatype.

I want solution in MySQL as It is possible in MS SQL. So I hope it would also be in MySQL.

MySQL will truncate any insert value that exceeds the specified column width.

to make this without error try switch your SQL mode to not use STRICT.

Mysql reference manual


EDIT:

To change the mode

This can be done in two ways:

  1. Open your my.ini (Windows) or my.cnf (Unix) file within the MySQL installation directory, and look for the text "sql-mode".

Find:

Code:

# Set the SQL mode to strict 
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Replace with:

Code:

# Set the SQL mode to strict 
sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Or

  1. You can run an SQL query within your database management tool, such as phpMyAdmin:

Code:

SET @@global.sql_mode= '';
