一、Sql Server插入方案介紹

關(guān)于 SqlServer 批量插入的方式，有三種比較常用的插入方式，Insert、BatchInsert、SqlBulkCopy,下面我們對比以下三種方案的速度

1.普通的Insert插入方法

public static void Insert(IEnumerable<Person> persons)
{
using (var con = new SqlConnection(“Server=.;Database=DemoDataBase;User ID=sa;Password=8888;”))
{
con.Open();
foreach (var person in persons)
{
using (var com = new SqlCommand(
“INSERT INTO dbo.Person(Id,Name,Age,CreateTime,Sex)VALUES(@Id,@Name,@Age,@CreateTime,@Sex)”,
con))
{
com.Parameters.AddRange(new[]
{
new SqlParameter(“@Id”, SqlDbType.BigInt) {Value = person.Id},
new SqlParameter(“@Name”, SqlDbType.VarChar, 64) {Value = person.Name},
new SqlParameter(“@Age”, SqlDbType.Int) {Value = person.Age},
new SqlParameter(“@CreateTime”, SqlDbType.DateTime)
{Value = person.CreateTime ?? (object) DBNull.Value},
new SqlParameter(“@Sex”, SqlDbType.Int) {Value = (int)person.Sex},
});
com.ExecuteNonQuery();
}
}
}
}
