EF执行SQL语句和存储过程

 1 string sql = @"INSERT INTO region(RegionID, RegionDescription) VALUES(@regionId, @regionDescription)";
 2                 var result = context.Database.ExecuteSqlCommand(sql,
 3                     new MySqlParameter("@regionId", 5),
 4                     new MySqlParameter("@regionDescription", "Center"));
 5                 if (result >= 1)
 6                 {
 7                     Console.WriteLine("插入新数据成功");
 8                 }
 9                 else
10                 {
11                     Console.WriteLine("插入数据失败");
12                 }
13                 string sql = @"DELETE FROM region WHERE RegionID = @regionId";
14                 var result = context.Database.ExecuteSqlCommand(sql,
15                     new MySqlParameter("@regionId", 5));
16                 if (result >= 1)
17                 {
18                     Console.WriteLine("删除数据成功");
19                 }
20                 else
21                 {
22                     Console.WriteLine("删除数据失败");
23                 }

1 string sql = @"SELECT RegionID, RegionDescription FROM region";
2                 var result = context.Database.SqlQuery<Region>(sql);
3                 foreach (Region region in result)
4                 {
5                     Console.WriteLine("Region = {0}, RegionDescription = {1}",
6                         region.RegionId, region.RegionDescription);
7                 }

1 var result = context.Database.SqlQuery<Region>(sql);
