In your example result you have 2 In columns and 2 Out columns. But what happens if a person goes in and out 3 or 4 times a day?

if a person goes in and out 3 or 4 time a day, one field will get null...

Don't quite understand. What field?
What I mean is that can a person go in and out undefined number of times during the same day? If he can, do you plan to use dynamic amount of columns (person, in1, out1, in2, out2, in3, out3...). Since this is very hard to achieve using plain sql

Oh sorry.
No over that columns bro.
that columns is (EmpID,Date,In1,Out1,In2,Out2) so each employee will have 4 attendants but some day they will absent in afternoon so their attendants will be just only 2 so
in columns In2, Out2 data will null. More is number of employee.
at the first i posted, i want to change data in Employee table like table under it. (hm... maybe is called crosstab.)

I have already contacted their support team 15 days back , even asking them as to how to go about if i have to purchase the licensed copy of the product. but their answer is inconclusive and way of the track ......
Well what i have gathered so far is that company is very discreet and miser in disclosing any of their trade secrets regarding the product and hardly there is any more information regrading it available on web itself, i hardly found anything substantial so far.....

I wouldn't expect them to reveal trade secrets, but they should have a decent support dept.

That may be the problem, I wouldn't give much support for a free version.
But, I would say, if they don't offer decent support use another product, there are plenty of other tools out there.

There is necessary to create foreign key relationship between tables when we create database. I create a database and define references between the tables but could not define any physical relation between tables.
Please advice, I need your help
Cheers

If you ask if it is necessary, it isn't. An application can be built without using foreign keys. However I would recommend to use them since correctly used, they make the life a whole lot easier.

The relation is not quite physical, but logical between two tables. In order ro use foreign key you must have primary key or unique key on master table and then you can define foreign key on the detail table. See examples A and B in CREATE TABLE[^]

Hi,
We have a real time application that responds to user's input. The app uses SQL 2005 Express. We observed the following.
After the application idles for a while, the first access to the database takes a few seconds to process. Then, consecutive accesses are nuch faster. The SQL Standard does not show this poor performance after the idling.
Any comments and suggestions are welcome.
Best,
Jun

Check the power savings settings on the machine that is running SQL Express. Maybe the disks have spun down during the idle period. That would cause a delay
Does it have anything to do with the type of query that is being executed ? Large select (causing a full table scan), large insert,update or delete ?
Interesting problem.

By idling, I meant the app does not use database for a while. The app is running at all times.
Best,

There could be several reasons for this. Basically SQL Express uses the same codebase than Standard so most likely there are environment, configuration or schema (mainly indexes) differences.
One thing could be that buffer cache is loosing already read pages thus forcing physical reads next time. Is the memory usage defined as dynamic and are there other applications eating up the memory from the machine?
Also you could check from database options that the database is not closed automatically and if connection pooling is used at client side, that the lifetime for a connection in the pool is sufficient (connection string options).

Hi,
interesting.
if everything else fails, I suggest you add a "keep kicking" thread (or a Windows.Forms.Timer) that periodically performs a simple query, just to keep the disk, the database, and everything else awake.

I have noticed poor performance on SQL Express vs. Standard and the performance was cured by adding indexing that I thought were done by default.
Also, SQL server express can be run as a file based database. If there are no open connections the database engine would not be running and would go out of process. So the first access problem would occur quite frequently with this type of set-up too.
Really, just tweak stuff one at a time until something works.
