在 mysql 中创建表和数据库时出现错误 1064 (42000)

Question

I am getting following error while executing my mysql query via a.sql script, but couldn't tell what is causing this error.

I am using mysql Ver 8.0.23 for macos10.15 on x86_64 (MySQL Community Server - GPL)

Error:

ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '/Users/shivamshekhar/Documents/Others/chat-app-backend/scripts/mysql/db.sql' at line 1

.sql file

CREATE DATABASE IF NOT EXISTS `chat_app`;  

USE `chat_app`;  

CREATE TABLE IF NOT EXISTS `user_details` (
    `id` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, 
    `name` VARCHAR(255) NOT NULL, 
    `password` VARCHAR(255) NOT NULL, 
    `created_at` DATETIME DEFAULT CURRENT_TIMESTAMP, 
    `updated_at` DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, 
    INDEX `idx_name` (`name`), 
    CONSTRAINT `uc_name` UNIQUE (`name`)
);

Terminal command:

mysql -u admin -ppassword -e ~/Documents/Others/chat-app-backend/scripts/mysql/db.sql

Answer 1

-e command means "execute the command", not "load and execute source file".

Send the source file to the client via stdin:

mysql -u admin -ppassword < ~/Documents/Others/chat-app-backend/scripts/mysql/db.sql

Or provide according command to the client:

mysql -u admin -ppassword -e "SOURCE ~/Documents/Others/chat-app-backend/scripts/mysql/db.sql"

Answer 2

The syntax is INT UNSIGNED , not UNSIGNED INT . In addition, NOT NULL is redundant on a PRIMARY KEY . So try this:

CREATE TABLE IF NOT EXISTS `user_details` (
    `id`  INT UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
    `name` VARCHAR(255) NOT NULL, 
    `password` VARCHAR(255) NOT NULL, 
    `created_at` DATETIME DEFAULT CURRENT_TIMESTAMP, 
    `updated_at` DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, 
    INDEX `idx_name` (`name`), 
    CONSTRAINT `uc_name` UNIQUE (`name`)
);

Answer 3

As already highlighted, it has to be int unsigned. In case there is any partition column in the data base, that could be added at the end, specifying the compression type. (Depending upon the context)

CREATE TABLE IF NOT EXISTS user_details ( id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255) NOT NULL, password VARCHAR(255) NOT NULL, created_at DATETIME DEFAULT CURRENT_TIMESTAMP, updated_at DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, INDEX idx_name ( name ), CONSTRAINT uc_name UNIQUE ( name ) ) partitioned by () stored as parquet (compression =<"compression type">);
