我在 sql server 中插入数据。这里是代码:
SqlParameter[] param = new SqlParameter[1];
param[0] = new SqlParameter();
param[0].ParameterName = "@Exch";
param[0].SqlDbType = SqlDbType.Int;
param[0].Value = "BSE";
formObjSqlConnection.SQLConnection.Executes("LPExch..DeleteVarMargin", param);
foreach (BseVar objBseVar in objListNseData)
{
currentIndex++;
param = new SqlParameter[10];
param[0] = new SqlParameter();
param[0].ParameterName = "@Exch";
param[0].SqlDbType = SqlDbType.Char;
param[0].Value = "BSE";
param[1] = new SqlParameter();
param[1].ParameterName = "@Symbol";
param[1].SqlDbType = SqlDbType.Char;
param[1].Size = 10;
param[1].Value = objBseVar.Symbol;
param[2] = new SqlParameter();
param[2].ParameterName = "@Series";
param[2].SqlDbType = SqlDbType.Char;
param[2].Value = "EQ";
param[3] = new SqlParameter();
param[3].ParameterName = "@SecurityVar";
param[3].SqlDbType = SqlDbType.SmallMoney;
param[3].Value = objBseVar.SecurityVar;
param[4] = new SqlParameter();
param[4].ParameterName = "@IndexVar";
param[4].SqlDbType = SqlDbType.SmallMoney;
param[4].Value = 0;
param[5] = new SqlParameter();
param[5].ParameterName = "@VarMargin";
param[5].SqlDbType = SqlDbType.SmallMoney;
param[5].Value = objBseVar.IndexVar;
param[6] = new SqlParameter();
param[6].ParameterName = "@AdhocMargin";
param[6].SqlDbType = SqlDbType.SmallMoney;
param[6].Value = objBseVar.SecurityVar - objBseVar.IndexVar;
param[7] = new SqlParameter();
param[7].ParameterName = "@VarMarginRate";
param[7].SqlDbType = SqlDbType.SmallMoney;
param[7].Value = objBseVar.IndexVar;
formObjSqlConnection.SQLConnection.Executes("LPExch..UpdateOrAddCashVarMarginBSE", param);
if (Convert.ToInt32(1 / progressChange * currentIndex) <= 100)
objImportMaster.UpdateProgressBar(Convert.ToInt32(1 / progressChange * currentIndex));
}
formObjSqlConnection.SQLConnection.Executes("LPExch..UpdateCashVarMarginBSEScripNo");
有没有其他方法可以在数据库中插入数据。问题是数据库需要太多时间来插入数据。另外我正在更新其他 UI 中的进度条。这是插入慢的原因吗?我们可以使用任何其他方式插入数据吗?
