Actually, you're asking for this output!, if you dont want a decimal, then simply skip it! here
SELECT ROUND(2.792) FROM ....;
All generalizations are wrong, including this one!

Actually i want last two digit i mean if i have value 2, 2.7312467 and 2.796 then the output should be 2.00, 2.73 and 2.79
thanks for the code but it's giving me error "The round function requires 2 to 3 arguments."
CODE
select round(2.792) as ID
select round(2.796) as ID
OUTPUT
Msg 189, Level 15, State 1, Line 7
The round function requires 2 to 3 arguments.
Msg 189, Level 15, State 1, Line 8
The round function requires 2 to 3 arguments.

Q: Do you know what the hell is "Rounding"?? 
A: It is bringing the number to the closest whole number, "and in case you specify a decimal place(s), to the closest number of those decimals"
then 2.01 >> 2
and 2.55 >> 3

Then give it a 0 as the second parameter
SELECT ROUND(2.88,0)...

An old trick
declare @a float,@b float
select @a = 2.796, @b = 2.792
select round(@a - 0.005,2),round(@b - 0.005,2)
Both return 2.79. Its because round follows the maths rule of going up at .5 and over.

thanks dear.
it's working now, But i have one question you add 0.005 to the value, should every time we have to add 0.005 or you add it with some specific reason i mean i found my value (2.792 or 2.796) is with 3 digit and you add 0.005 which also have 3 digit if my value is more then 3 digit (2.79546) then should i add the same 0.005 value or i have to add 0.00005
can you clarify me...

It doesn't matter how long your number is, you need the same number of zeros as you want to round to. For example, if you want to round to 4 decimal places you use .00005, to round to 3 decimal places you use .0005
Hope this clarifies.

Hi all,
I want to write a store proc that queries across db, and whenever I am at one db location, i want to query for a list of records which I want to store because I am going to perform an update on each of these based on the results that i gather earlier. once im done, ill loop and move on the next db.
Looks something like this;
1. Retrieve all db links
2. Loop to go to the first db link provided
3. Query table @current db link and use cursor to store the results
4. Loop results to perform update
5. Once, done go back to (2) and move to the next db until there is no more left
Now the question is, how to I access query across db dynamically? Currently i am using EXECUTE IMMEDIATE method. Next, can i use crusor when using execute immediate?
Any advice? Greatly appreciate it
Regards, Jensen

You can either use DBMS_SQL package to define and use the cursor or simply use REF CURSOR.

Try something like this
create table #b1(usr sysname, flag char(1), val float)
insert into #b1(usr,flag,val) select 'a','n',22
insert into #b1(usr,flag,val) select 'b','Y',22
insert into #b1(usr,flag,val) select 'a','n',11
insert into #b1(usr,flag,val) select 'b','n',2
insert into #b1(usr,flag,val) select 'a','Y',100
select usr,sum(case when flag = 'y' then val else val * -1 end) from #b1 group by usr

If I understood you correctly, you're having a problem with the query because, based on your sample material, it returns 4 rows instead of 3.
If this is correct, you should use for example GROUP BY clause, but then you cannot have individual values from table2, only aggregates. So you should choose what do you want from table2. For example:
select table1.rallno,
table1.mark,
max(table2.refrence_name)
from table1 left join table2 on table1.rallno=table2.rallno
group by table1.rallno,
table1.mark

Hi, a newbie to asp.
I have the following code which when run complains with error 'expected end of statement.'
What it is suppose to do is read in the ip address of a remote host and then do a comparison to an ip field within the database. It should also time stamp this entry if logic permits.
]]>
Would appreciate some help from anyone of you gurus of asp,sql out there.
Regards Phil.

Without seeing the query you have already built, answering the question is quite difficult, so what's your query like?

mysql provides u wid very friendly and easy to use interface.If u have ever logged in u might feel it right. Try creating a new database in it and then u can create tables and other stuff u want inside ur database. Using mysql is more like using IE.
well but the connection string is a bit lenghty.U use a odbc data provider for mysql.
connection string is:
"Driver =MYSQL ODBC <version> Driver ; Server= <servername> ; port=<port>;
option= 16387; Database=<database>; uid=<userid>;
Pwd=<password>;"

The relation databases should change the existing structure to tree like structures so that items of a sub item should be clearly represented
