Laravel: String data, right truncated: 1406 Data too long for column

You need to create a new migration, register it with composer du command and run php artisan migrate command to change type of the column:

Schema::table('the_table_name', function (Blueprint $table) {
    $table->string('hotel', 255)->change();
});

On your local development, try changing the column type to:

$table->longText('columnName')

from your migration file. That solved it for me. But if you have gone live, then create a new migration just as Alexey has suggested and then use longText() column type.

I was storing pictures as base64 on a text colum so I got a SQL error:

SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'picture' at row 1 

I did my migration as

$table->text('picture')

then I changed de column picture as:

$table->mediumText('picture')

I realiced that text column allows to store only 64 KB

TEXT: 65,535 characters - 64 KB MEDIUMTEXT: 16,777,215 - 16 MB LONGTEXT: 4,294,967,295 characters - 4 GB
