AbpAuditLogs (Update-Database) : 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 '(6) NOT NULL,

env: ABP v3.8.1 .Net Core 2.1.0

StackTrace: PM> update-database Applying migration ‘20180821092341_Init’. Failed executing DbCommand (5ms) [Parameters=[], CommandType=‘Text’, CommandTimeout=‘30’] CREATE TABLE AbpAuditLogs ( Id bigint NOT NULL AUTO_INCREMENT, TenantId int NULL, UserId bigint NULL, ServiceName varchar(256) NULL, MethodName varchar(256) NULL, Parameters varchar(1024) NULL, ExecutionTime datetime(6) NOT NULL, ExecutionDuration int NULL, ClientIpAddress varchar(64) NULL, ClientName varchar(128) NULL, BrowserInfo varchar(512) NULL, Exception varchar(2000) NULL, ImpersonatorUserId bigint NULL, ImpersonatorTenantId int NULL, CustomData varchar(2000) NULL, CONSTRAINT PK_AbpAuditLogs PRIMARY KEY (Id) ); MySql.Data.MySqlClient.MySqlException (0x80004005): 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 ‘(6) NOT NULL, ExecutionDuration int NULL, ClientIpAddress varchar(’ at line 8

Step:

1. download sample from ABP website, selected “.net core” & “EF”
2. modify database from sql server to mysql. a. modify connection string in appsettings.json jin Web.Host project. b. modify “UseSqlServer” to “UseMySql” in **DbContextConfigurer class file. c. delete migrations files in Migrations directory. d. add reference “Pomelo.EntityframeworkCore.Mysql” v2.1.1 in Web.Host & EntityFrameworkCore project.
3. input command “Add-Migration” in Package Manager Console
4. input command “Update-Database” in Package Manager Console

Summary: database-code-first create C# “DateTime” type to “datetime(6)” in migration class。 ExecutionTime = table.Column<DateTime>(nullable: false),

Solution： add mysqlOption to UseMySql funtion.

The final code like this:

  public static class XXXContextConfigurer
    {
        public static void Configure(DbContextOptionsBuilder<SCDbContext> builder, string connectionString)
        {
            //
            builder.UseMySql(connectionString, 
                mySqlOptionsAction => mySqlOptionsAction.ServerVersion(new Version(), ServerType.MySql));
        }

        public static void Configure(DbContextOptionsBuilder<SCDbContext> builder, DbConnection connection)
        {
            //
            builder.UseMySql(connection);
        }
    }

hi @muzizongheng

I didn’t use mysql in my project. You can see from the error message that this problem is EFCore+Mysql.

You can check if there is a solution at https://github.com/PomeloFoundation/Pomelo.EntityFrameworkCore.MySql.
