Question

数据库版本：10.1.35-MariaDB

字符集：utf8

我遇到错误：Specified key was too long; max key length is 767 bytes，所以我将列长更改为255。但是我需要在列中允许varchar(1000)，所以当我在db列中输入大数据时，它说：Warning: #1265 Data truncated for column

如何允许大数据？

Answer 1

尝试使列长度最大，然后它将起作用

    "private": true,
    "scripts": {
        "dev": "npm run development",
        "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
        "watch": "npm run development -- --watch",

    },

感谢@ P.Salmon。

列长度限制仅适用于键。所有其他列的长度都可以。
