DataSource Controls :: Loop Through 1000 Records ("while" Not To Be Used)

May 7, 2010

I have 1000 records in a table .

Now I want to Loop through all them ,extracting value of one particular column in each row (which is then used to find value in other table)

How should I proceed .

I don't want to use WHILE as it slows down my Stored procedure

DataSource Controls :: Loop Through The Records Of A Table?

Mar 19, 2010

im learning t-sql, infact i needed its while-loop to loop through records of a table, i found this code in some book:

[Code]....

i understand here that setting the rowcount variable to 1 will force the select statements to return only one record, do all above select statements return one record only?

if the underlined select statement returns one record everytime it is executed, isn't it supposed to return the same first record of the table everytime? is there a better way to loop through a table's records?

Architecture :: Loop Through Large Collection 100 Records At A Time?

Jan 21, 2011

I am building a small mass email application for my department. Which basically emails out a notice to a large list of email addresses. Because the company email server limits the amount of email addresses that can be contained in a single email I have to break the list apart into smaller 100 email groups.

I've create the query to pull all email addresses needed, stuffed them into a collection but I am not sure how to grab 100 emails at a time and send it off to another sub to perform the email send before grabbing the next 100.

This is what I have so far.

Databases :: MySql Transaction Inside A Loop - Delete A Bunch Of Records

Sep 30, 2010

I'm trying to delete a bunch of records in mysql. The record info to delete (userid, name) is stored in an arraylist. It seems to only delete the first record and gives an error ("Transaction has already been rolled back or is not pending.") afterwards. I have the transaction commit inside the loop which I think is the issue but not sure how to go further if I bring it outside of the loop. Here's the relevant bits of the code.

try
{
ArrayList alist = new ArrayList();
//alist gets populated with data like (12345,robot)(23456,car) here.
MySqlConnection conn2 = new MySqlConnection(query_connection);
conn2.Open();
MySqlCommand command2 = conn2.CreateCommand();
MySqlTransaction mytransaction;
mytransaction = conn2.BeginTransaction();
command2.Transaction = mytransaction;
for (int i = 0; i < alist.Count; i++)
{
string[] s = alist[i].ToString().Split(',');
try
{
command2.CommandText = "DELETE from users_settings WHERE UserID=" + s[0].ToString();
command2.ExecuteNonQuery();
command2.CommandText = "DELETE from users WHERE ID=" + s[0].ToString();
command2.ExecuteNonQuery();
mytransaction.Commit();
}
catch (Exception e){
mytransaction.Rollback();
}
}
}
catch(Exception e){

DataSource Controls :: Resizing Two Dimensional Array - Filling Data In Loop

Mar 11, 2010

My original code was in classic vb. and could use redim array to resize them. I was porting the code to c# now and lately i have run into an issue to resize a 2 dimensional array. The thing here is I have a 2 dimensional array whose 2nd dimension needs to be increased dynamically as needed to accommodate the data. For say

String[,] ary1=new String[2,10];

I'm doing some operation in a loop and filling in the data in ary1. And if the loop still continues, on reaching the ary1 upper bound i need to increase the size further to accommodate 10 more rows. I tried couple of ways to copy it to a bigger array and assign it back to the current array. but somehow dint work.
