以下提供3中方式将DataTable中的数据插入到SQL SERVER 数据库:
一:使用sqlcommand.executenonquery()方法插入
foreach (DataRow datarow in datatable.Rows) { string sql = "INSERT INTO [Table_1] ([CompanyName],[CompanyCode],[Address],[Owner],[Memo])" + "VALUES('" + datarow["CompanyName"].ToString() + "'" + ",'" + datarow["CompanyCode"].ToString() + "'" + ",'" + datarow["Address"].ToString() + "'" + ",'" + datarow["Owner"].ToString() + "'" + ",'" + datarow["Memo"].ToString() + "')"; using (SqlConnection sqlconn = new SqlConnection(connectionString)) { sqlconn.Open(); SqlCommand sqlcommand = new SqlCommand(sql, sqlconn); sqlcommand.ExecuteNonQuery(); sqlconn.Close(); } }二:使用sqldataadapter.update(dataset,tablename);
SqlCommand insertcommand = new SqlCommand("INSERT INTO [Table_1]([CompanyName],[CompanyCode],[Address],[Owner],[Memo])" + "VALUES(@CompanyName, @CompanyCode,@Address,@Owner,@Memo)",new SqlConnection(connectionString)); insertcommand.Parameters.Add("@CompanyName", SqlDbType.NChar, 50, "CompanyName"); insertcommand.Parameters.Add("@CompanyCode", SqlDbType.NChar, 25, "CompanyCode"); insertcommand.Parameters.Add("@Address", SqlDbType.NChar, 255, "Address"); insertcommand.Parameters.Add("@Owner", SqlDbType.NChar, 25, "Owner"); insertcommand.Parameters.Add("@Memo", SqlDbType.NChar, 255, "Memo"); sqldataadapter.InsertCommand = insertcommand; sqldataadapter.Update(dataset, "Table_1"); 三:使用sqlbulkcopy.writetoserver(datatable) SqlBulkCopy sqlbulkcopy = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.UseInternalTransaction); sqlbulkcopy.DestinationTableName = "Table_1";//数据库中的表名 sqlbulkcopy.WriteToServer(dataset.Tables[0]);
