OK, sorry for being the klutz here but could you be a little bit more specific please?
I am familiar with the MIN() function as in SELECT MIN(OrderDate) FROM Orders but I'm not sure how to use it with the HAVING clause.

If the explanation was not clear, you need to learn how to use agregates in sql statement clauses.

So sorry for wasting your time. I'm sure the explanation was clear and I know that I need to learn how to use aggregates in sql statement clauses - which is exactly why I came here.
My apologies again if I asked for too much help. Here's hoping that someone else might be a little bit more forgiving.

Have you looked up the HAVING clause and realized how easy it actually is?
|
|
|
|

You could always do this:
select o1.* from orders o1<br />
where o1.orderdate = (select<br />
o2.orderdate from orders o2<br />
where o1.custid = o2.custid)

The only tricky part is getting the OrderDescr field into your result. There are a few ways to accomplish this and I have one listed below (TSQL) that should work. Life would be easier if you had a primary key on the order table.
SELECT
*
FROM
Orders o1
INNER JOIN
(SELECT
custID,
MIN(OrderDate)
FROM
Orders
GROUP BY
custId) o2
ON (o1.CustId = o2.CustId AND
o1.OrderDate = o2.OrderDate)

In your example, just select where id = 1, 2 or 4.
If you are looking for more complex behaviour, then you need to specify what it is that you are looking for, as we can't divine it from your example.

Acctuly this is my table
id PD_Id Remark
1 1 Good
2 2 Bad
3 2 fair
4 3 Bad
5 3 Good
In this i want the select query for the following result
id PD_Id Remark
1 1 Good
2 2 Bad
4 3 Bad
|
|
|
|
|
Id, PD_ID, Remark are the 3 fields that i have used in this table.
|
|
|
|
|
There is (almost) nothing consistent or special about your desired result set (no specific visible relationship between the value of remark, id , PD_ID).
The resultset can be produced with
"select top 3 id,pd_Id,remark from table where Remark in ('Good','Bad') order by PD_Id ASC"
But that does not seem particularly useful.

In Enterprise Manager, right click on the table and select Manage Triggers. The listbox at the top allows you to view the different triggers - by default it shows the New trigger option.

This will give you a list of all triggers on a table:

You might want to look at this too:

Hello everyone:
I have a MySQL server running on a linux that is working properly, and i have errors trying to connect to the server on a windows NT client using ODBC. The error i am getting is Can't connect to MySQL 10060. The driver i am using is ODBC 3.51,(i wish to create a vb app using the driver to access the database) I am quite sure that the parameters that i specified for the host name etc are correct. I even downloaded the MySQL control centre to test the connection to the MySQL linux server, but it still doesnt work. I tried using the same ODBC driver and the same windows client to connect to another dummy MySQL server running on a remote windows PC and it works. Also I have a website coded in PHP that can access the MySQL database on any windows pc, so it couldn't possibly be that the MySQL server blocks out my clients IP address right?
Please help Thanks in advance

It shouldn't. Sounds like problem on client end...

How much expensive openning and closing connection is when connection pool is used ???
Assume I invoke four stored procedures in a page , I open and close the connection for invoking each . How much will it affect the performance of that page ??
calling this in a page :
<br />
Connection.Open();<br />
Connection.Close();<br />
<br />
Connection.Open();<br />
Connection.Close();<br />
<br />
Connection.Open();<br />
Connection.Close();<br />
<br />
Connection.Open();<br />
Connection.Close();<br />
Is it worth replacing it with this. I have made the site like above.It is so hard for me to replace that. What is your suggestion ?
<br />
Connection.Open();<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
Connection.Close();<br />
|

|

I think the first way is acceptable. The close method returns connection to the pool and open method get a freely connection from pool. The second way seems to be a bit better performance but it will charge a lots of cost of changing sources

I don't have much knowledge in in programming and I need some help with this issue. I am using SQL 2005.
I have a sales table in which I need to compare the difference in sales price of a house. Here is what the data would look like.
ID SalePrice DateSale
2 90000 01/01/94
2 108500 05/12/04
2 115300 09/01/06
45 13500 03/01/54
45 98500 10/01/06
What I need, is a routine that would calulate one sale value from the preceeding for like ID. In the first case, there would be two resulting values calculated 18,500 and 6,800. These values would then be stored in a new table.
I hope I have explained this well.

Can you kindly examplify your input and output?
|
|
|
|
|
The example is simply a home sales table set up this way
ID
DateSale
SaleAmount
The table tracks all the sales that takes place in a community for the homes. A single home can be sold numerous times over its lifespan. So the challenges is to compare one sale amount to the next by date of sale. I need to calculate the difference between each sale and determine the % increase or decrease.
I hope this helps.
