FreeSql.Provider.MySqlConnectorFreeSql基于社区提供的最新的MySqlConnectoropen in new window驱动的实现,兼容性、性能都比FreeSql.Provider.MySql好,且支持多种数据库,如:MySQL Server, MariaDB, Percona Server, Amazon Aurora, Azure Database for MySQL, Google Cloud SQL for MySQL, OceanBase

并且支持BulkCopy,推荐使用

如果你使用 FreeSql.Provider.MySql 发生了以下错误,请替换到 FreeSql.Provider.MySqlConnector:

  • The given key '0' was not present in the dictionary.
  • The given key '25653' was not present in the dictionary.
  • The given key '26995' was not present in the dictionary.
  • The given key '28261 was not present in the dictionary.
  • The given key '65535' was not present in the dictionary.
  • The type initializer for 'MySql.Data.MySqlClient.Replication.ReplicationManager' threw an exception.
  • Parameter '@xxx' must be defined.

ExecuteMySqlBulkCopy

  • 主键无值
public class Department
{
    [Column(IsPrimary = true, IsIdentity = true)]
    public long Id { get; set; }
    public string Name { get; set; }
}
List<Department> departments = new List<Department>()
{
    new Department() { Name ="部门1"},
    new Department() { Name ="部门2"},
    new Department() { Name ="部门3"}
};
fsql.Insert(departments)
    .InsertIdentity() //这行
    .ExecuteMySqlBulkCopy();
  • Id主键有值时
List<Department> departments = new List<Department>()
{
    new Department() { Id=1, Name ="部门1"},
    new Department() { Id=2, Name ="部门2"},
    new Department() { Id=3, Name ="部门3"}
};
fsql.Insert(departments)
    .ExecuteMySqlBulkCopy();
