Description

1.已经存在了一个sqlite3数据库，表结构已经通过sql语句被建立好了，建表语句如下：

CREATE TABLE tb_levels (
    -- level id is a unique id of a level, please ensure this.
    level_id     INTEGER                    NOT NULL,
    -- Duplicate names are allowed under the same group_id.
    name         TEXT                    NOT  NULL,
    code         INTEGER                 NOT  NULL,
    -- 0 or 1, 0-predefine 1-customize.
    source       INTEGER                 NULL DEFAULT 1
);

生成一个a.db的sqlite数据库文件。

2.使用AutoMigrate函数修改表结构，go代码程序如下：

package main

import (
    "fmt"

    "gorm.io/driver/sqlite"
    "gorm.io/gorm"
)

type TbLevels struct {
    LevelId uint64 `gorm:"level_id"`
    Name    string `gorm:"name"`
    Code    string `gorm:"code"`
    Source  int32  `gorm:"source"`
    GroupID int    `gorm:"group_uuid"`
}

func main() {
    dbPath := "./a.db"
    dbHandle, err := gorm.Open(sqlite.Open(dbPath), &gorm.Config{})
    if err != nil {
        fmt.Printf("Failed to open %s, error is %s.\n", dbPath, err.Error())
        return
    }
    err = dbHandle.AutoMigrate(&TbLevels{})
    if err != nil {
        fmt.Printf("Failed to auto migrate database, error is %s, retry.\n", err.Error())
    } else {
        fmt.Printf("Migrate database successfully.")
    }
}

go build 生成gormtest程序 3.运行gormtest程序，报错如下 ./gormtest

2024/11/12 11:41:54 table tb_levels__temp has no column named please [0.017ms] [rows:0] INSERT INTO tb_levels__temp(please,code,0) SELECT please,code,0 FROM tb_levels Failed to auto migrate database, error is table tb_levels__temp has no column named please, retry.

There is no column named please. Your defined struct with name TbLevels, and the created table by sql with table name tb_levels, none of them has a column named please, just exactly what the error shows up.

Why don't you read the error more carefully?

原始的数据库建表语句中本身就没有please这一列。我的理解是AutoMigrate内部在解析数据库建表语句的时候，用的逗号分割的schema，导致把please误认为是一个column，而实际上不是。

如果建表语句是下面这样

CREATE TABLE tb_levels (
    level_id     INTEGER                    NOT NULL,
    name         TEXT                    NOT  NULL,
    code         INTEGER                 NOT  NULL,
    source       INTEGER                 NULL DEFAULT 1
);

AutoMigrate函数是可以迁移成功的。
