当我尝试使用node_modules / .bin / sequelize db：migrate

进行迁移时，我收到此错误

我认为mysql2包会导致此错误

我很感谢您的帮助

首先，请确保您的config.json 不包含任何未加引号的值，例如此示例中的密码：

create table #tmp1
(
LicenseID int,
CompanyWindowId int,
CompanyCount int
)
GO
create table #tmp2
(
LicensedCompanyID int identity,
CompanyWindowId int,
CompanyID int,
LicenseID int
)
GO
insert into #tmp1 values (9,9,5),(12,9,2)
insert into #tmp2 (CompanyWindowId,CompanyID) values (9,10),(10,12),(10,14),(10,15),(10,16),(10,17),(10,18)
SELECT * from #tmp2
declare @licenseID int
declare @count int=1
declare @count2 int=1
declare @recordcount int
declare @CompanyCount int
select @recordcount=count(1) from #tmp1
WHILE @count2<=@recordcount
BEGIN
    select @licenseID=LicenseID,@CompanyCount=CompanyCount FROM (select *, row_number() over (order by licenseID) RID from #tmp1)T where  RID=@count2
    SET @count=1
    WHILE @CompanyCount>=@count
    BEGIN
        SET ROWCOUNT 1
        UPDATE #tmp2 SET LicenseID=@LicenseID WHERE LicenseID IS NULL
        SET @count+=1
    END

    SET @count2+=1
END
SET ROWCOUNT 0
SELECT * from #tmp2

drop table #tmp1
drop table #tmp2

如果这不能解决你的问题并且你有充分的理由相信它与mysql2包有关，请尝试将你的sequelize包降级到v3并使用mysql而不是mysql2

Answer 2

如果您使用命令＆＃34; sequelize init ＆＃34;要初始化项目，那么你应该检查你的config.json.Because默认情况下＆＃34; 端口＆＃34;字段不包括在内。同时，请确保您的 config.json 在此示例中不包含任何未加引号的密码。

{
 "my_env": {
    "username": "root",
    "password": 1234,
    "database": "my_db",
    "host"    : "localhost",
    "dialect" : "mysql"
  }
}

Sequelize db：migrate throw TypeError：数据必须是字符串或缓冲区
