problem reading datavalues to an arraylist

I have an SQL command below that works fine

"SELECT sum(Preference) FROM [projectDB].[dbo].[Vote] group by preference;

SqlDataReader

datareader = cmdPres.ExecuteReader();
ArrayList myArr =newArrayList();

when i read the data in the values i get are
10,14,10,17

I want to loop through the reader, then add the values to an arrayList. Then i want to check of the value in the arrayList is greater than 15 but it dosent work. I get an error message when i add
sum(Prefernece) to the arraylist, it will not allow me.

while (dreader.Read())
{
myArr.Add(datareader["sum(Preference)"].ToString());

if(myArr.? > 15)
{
Response.Write("Its greater than 15");
}
}

sorry,

think i posted this into the wrong section...its not really an sql problem.

but if anyone has any ideas they will be appriciated

ArrayList uses index to get the specific position's value. Because you use reader() to get the data, you have to add extra steps to do. Here is the clue

int position = 0;

while (dreader.Read())
{

myArr.Add(datareader["sum(Preference)"].ToString());

if((int)myArr[position] > 15)

{
Response.Write("Its greater than 15");
}

position++;

}

Hope it helps

I maked a following query and excuted it.
SELECT UT.shop, sum(UT.dcrate) , sum(UT.sellcnt)
FROM
(
(
SELECT SUBJ0.shop AS shop, 0 AS dcrate, sum(SUBJ0.sellcnt) AS sellcnt
FROM
(
SELECT
[shop]shop,
[brnd]brnd,

[sellterm]sellterm,
[tempseq]tempseq
FROM
"HULUCKS.dbo.x_sellinfo" T1
) SUBJ0
GROUP BY SUBJ0.shop
)
UNION ALL
(
SELECT SUBJ1.shop AS shop, sum(SUBJ1.dcrate) AS dcrate, 0 AS sellcnt
FROM
( SELECT
[shop]shop,

This should give the same result (if I am not wrong)
SELECT UT.shop, sum(UT.dcrate) , sum(UT.sellcnt)
FROM
(
SELECT SUBJ0.shop AS shop, 0 AS dcrate, SUBJ0.sellcnt AS sellcnt
FROM
"HULUCKS.dbo.x_sellinfo" SUBJ0
UNION ALL
SELECT SUBJ1.shop AS shop, SUBJ1.dcrate AS dcrate, 0 AS sellcnt
FROM
"HULUCKS.dbo.x_shop" SUBJ1
) UT
GROUP BY UT.shop|||Thank you for quickly response.
I need of next case too.
SELECT UT.shop, sum(UT.dcrate) , sum(UT.sellcnt)
FROM
(
(
SELECT SUBJ0.shop AS shop, 0 AS dcrate, sum(SUBJ0.sellcnt) AS sellcnt
FROM
(
SELECT
[shop]shop,
[brnd]brnd,
[item]item,
[seq]seq,
[color]color,
[size]size,
[sellqty]sellqty,
[sellamt]sellamt,
[sellcnt]sellcnt,
[sellterm]sellterm,
[tempseq]tempseq
FROM
"HULUCKS.dbo.x_sellinfo" T1
) SUBJ0
GROUP BY SUBJ0.shop
)
UNION ALL
(
SELECT SUBJ1.shop AS shop, sum(SUBJ1.dcrate) AS dcrate, 0 AS sellcnt
FROM
( SELECT
T2.[shop_type]shop_type,
T1.[shop]shop,
T1.[sellqty]sellqty,
T1.[dcrate]dcrate,
T1.[sellamt]sellamt
FROM
"HULUCKS.dbo.x_sellinfo" T1
INNER JOIN "HULUCKS.dbo.x_shop" T2 ON T2.[shop]shop = T1.[shop]shop
) SUBJ1
GROUP BY SUBJ1.shop
)
) UT
GROUP BY UT.shop
In this case also raise same error.
But no error at the next time.
SELECT UT.shop, sum(UT.dcrate) , sum(UT.sellcnt)
FROM
(
(
SELECT SUBJ1.shop AS shop, sum(SUBJ1.dcrate) AS dcrate, 0 AS sellcnt
FROM
( SELECT
T2.[shop_type]shop_type,
T1.[shop]shop,
T1.[sellqty]sellqty,
T1.[dcrate]dcrate,
T1.[sellamt]sellamt
FROM
"HULUCKS.dbo.x_sellinfo" T1
INNER JOIN "HULUCKS.dbo.x_shop" T2 ON T2.[shop]shop = T1.[shop]shop
) SUBJ1
GROUP BY SUBJ1.shop
)
) UT
GROUP BY UT.shop

To my thinking, it can solve by patch SP of MS SQLServer 2000.
Is this right?

The only place I have heard is in SSL Connections.
Is that the error that it gives?
It seems to be correct syntactically and the table seems to exist.
Maybe one of the MVPs might have a better insight on the service packs|||Kym,
[HULUCKS.dbo.x_shop] is a very strange table name. My guess
is that you have a table named x_shop in a database called HULUCKS,
but that you don't have a table named [HULUCKS.dbo.x_shop].
This would mean, however, that the query omnibuzz asked you to
run does not work. Are you sure you ran it exactly, including the
" characters?

Try removing the " characters around the table name.
