Hi,

I have 5 rows in a dataset. I want get and execute the data from dataset(ds) one by one. How can I do the same.

Ex:
SqlParameter[] arParameters = new SqlParameter[1];
arParameters[0] = new SqlParameter("@iBatchID", objBatchContent.BatchID);
ds = dh.ExecuteDataSet("[dbo].[uspGetInterimBatchID]", CommandType.StoredProcedure, arParameters);
if (ds != null && ds.Tables[0].Rows.Count > 0)
{
foreach (DataRow dr in ds.Tables[0].Rows)
{
int name=0;
for(int i=0;i<ds.Tables[0].Rows.Count; i++) // Here I have morethan 5 rows in the ds, I want get the data one by one from the ds.
{
name = Convert.ToInt32(ds.Tables[0].Rows[0]["I_Interim_batch_ID"]);
CenterManager.CopyInterimBatchContents(Convert.ToInt32(ddlBatch.SelectedValue), name.ToString(), sCreatedBy, dtCreatedOn);
}
}
}

0	Dear Karthik, Here is an alternative way to do this:- if (ds != null && ds.Tables[0].Rows.Count > 0) { foreach (DataTable dt in ds.Tables) { int name = 0; foreach (DataRow dr in dt.Rows) { name = Convert.ToInt32(dr["I_Interim_batch_ID"]); CenterManager.CopyInterimBatchContents(Convert.ToInt32(ddlBatch.SelectedValue), name.ToString(), sCreatedBy, dtCreatedOn); } } } Happy Coding If it helps you or directs U towards the solution, MARK IT AS ANSWER Karthik2010_Mca, if this helps please login to Mark As Answer. \| Alert Moderator

Dear Karthik,

Here is an alternative way to do this:-

if (ds != null && ds.Tables[0].Rows.Count > 0)

        {

            foreach (DataTable dt in ds.Tables)

            {

                int name = 0;

                foreach (DataRow dr in dt.Rows)

                {

                    name = Convert.ToInt32(dr["I_Interim_batch_ID"]);

                    CenterManager.CopyInterimBatchContents(Convert.ToInt32(ddlBatch.SelectedValue), name.ToString(), sCreatedBy, dtCreatedOn); 

                }

            }

        }

0	Dear Karthik, I have modify the your code. You can use the below code to get your morethan 5 rows SqlParameter[] arParameters = new SqlParameter[1]; arParameters[0] = new SqlParameter("@iBatchID", objBatchContent.BatchID); ds = dh.ExecuteDataSet("[dbo].[uspGetInterimBatchID]", CommandType.StoredProcedure, arParameters); if (ds != null && ds.Tables[0].Rows.Count > 0) { int name=0; foreach (DataRow dr in ds.Tables[0].Rows) { name = Convert.ToInt32(dr["I_Interim_batch_ID"]); CenterManager.CopyInterimBatchContents(Convert.ToInt32(ddlBatch.SelectedValue), name.ToString(), sCreatedBy, dtCreatedOn); } } Here I want to tell you some thing 1. As you said that "I have 5 rows in a dataset". This is wrong. There is not rows present in any data-set. I mean to say that ds.Tables[0].Rows means there are 5 rows in datatable and not dataset. 2. foreach (DataRow dr in ds.Tables[0].Rows) and for(int i=0;i<ds.Tables[0].Rows.Count; i++) are doing the same thing. So I have remove the one. Happy Coding If it helps you or directs U towards the solution, MARK IT AS ANSWER Karthik2010_Mca, if this helps please login to Mark As Answer. \| Alert Moderator

0	Dear Karthik, If you want to loop the datatable from ds then you can use the below code:- if (ds != null && ds.Tables[0].Rows.Count > 0) { foreach (DataTable dt in ds.Tables) { int name = 0; for (int i = 0; i < dt.Rows.Count; i++) { name = Convert.ToInt32(dt.Rows[0]["I_Interim_batch_ID"]); CenterManager.CopyInterimBatchContents(Convert.ToInt32(ddlBatch.SelectedValue), name.ToString(), sCreatedBy, dtCreatedOn); } } } Happy Coding If it helps you or directs U towards the solution, MARK IT AS ANSWER Karthik2010_Mca, if this helps please login to Mark As Answer. \| Alert Moderator

Dear Karthik,

If you want to loop the datatable from ds then you can use the below code:-

if (ds != null && ds.Tables[0].Rows.Count > 0)

        {



            foreach (DataTable dt in ds.Tables)

            {

                int name = 0;

                for (int i = 0; i < dt.Rows.Count; i++)

                {

                    name = Convert.ToInt32(dt.Rows[0]["I_Interim_batch_ID"]);

                    CenterManager.CopyInterimBatchContents(Convert.ToInt32(ddlBatch.SelectedValue), name.ToString(), sCreatedBy, dtCreatedOn); 

                }

            }

        }
