Better design!
Then you can update the record after it is inserted to calculated the applicationid field.
You will need to pad the ROW_NUMBER()/MAX value with leading zeros and combine that with the year datepart.
This is a better option as the ApplicationID field that is a human consumed piece of info is not used to identify the record.

I saw same problem like me.
but I didn't see best answer, like sample.

There is also a security reason for not doing this.
If someone sees that their id is "20110005" it is easy to guess that 20110004 and 20110006 are also valid.

That will be in specific format.
Mycroft is right, but it's half the story. Tables hold data, not information.
sankooo wrote: If the year changes to new year, I want to start from 00001. like that.
That's a composite column, and in the ideal world we try to keep the data atomic. That means that you can loose the date-part, as that's already encoded in the previous column. You also don't need the prefix-zeroes, those are merely there for presentation. Hence, all you need in the ApplicationID-row is a sequence-number; all other information is already present and the complete applicationID as you need can be calculated from the rest of the tuple.
The other half of the story is that we don't want to duplicate information, as that would be redundant (and thus, increases the chances for errors).
I'd suggest you read up on normalization[^] procedures.

I am using this code to view a news headline from mysql table but I want also to add one more thing please... I want to update a field named news_views (int) with +1 everytime someone views this article.. how can I do this please...
<?php
$news_id = $_GET['id'];
$conn = mysql_connect('mysql.jassimrahma.com', 'jassimdb', 'xxxxxxx');
$sql = "SELECT * FROM news WHERE news_id = '$news_id'";
mysql_select_db("jassimrahma", $conn) or die(mysql_error());
$result = mysql_query($sql, $conn) or die(mysql_error());
$count = mysql_num_rows($result);
if($count == 1)
{
$db_field = mysql_fetch_assoc($result);

Hi all,
DECLARE
@holidayCount AS int,
@startDate AS datetime,
@endData AS datetime,
@empCode AS VARCHAR(20)
SET @startDate='12/6/2011 00:00:00.000'
SET @endDate='12/8/2011 23:59:59.997'
SET @empCode='EMP001'
SET @holidayCount=(SELECT COUNT(*) FROM tbl_holidays WHERE
holidays BETWEEN @startDate AND @endDate)
--I am assuming that 'holidays' is a datetime field/column
SELECT empCode, name, (Counts + @holidayCount) As holidayCounts
FROM
(
SELECT a.empCode, b.name, (Count(*) as Counts
FROM tbl_leaveentry a,tbl_emp b
WHERE a.empCode=b.empCode AND
a.empCode=@empCode AND
a.entryDate @startDate and @endDate
GROUP BY by a.empCode,b.name
) AS temp
WHERE Counts + @holidayCount>3
From the above query i got the count but now i need to get the start date of the leave that an employee had applied.
eg. 'EMP001' had applied leave from 12/1/2011 to 12/8/2011
but i have only one date option that is the end date. once you select the date option like 12/8/2011 it searches the dates from 2days before like 12/6/2011 and 12/8/2011 and returns the employees who have taken leaves continuously but i need to get the start date of the leave applied by the employee.
eg. EMP001 had applied leave from 12/1/2011 to 12/8/2011
Please suggest that how can i do this task any help will be appreciated

How about subtracting count of leaves from endDate
like
SELECT @SDate = DATEADD (day, - @holidayCount, @endDate)
|

Hi,
select empcode,name,(counts+2) as leaves from (select a.empcode,b.name,count(*) as counts from tbl_leaveentry a,tbl_emp b where a.empcode=b.empcode and a.empcode='EMP001' and
a.entrydate between DATEADD(d,-2,'12/8/2011') and '12/8/2011'
group by a.empcode,b.name) as c where (counts+2) =3
The above code generates the report of the employee who have taken leave more than 3 days from the selected dates but i need to get the start date of the leave applied by the employee
eg: 12/1/2011 to 12/8/2011
Thanks in advance

What other fields are in tbl_leaveentry besides empcode,entrydate?
Do you have a field that indicates how may leave days were taken? There should be a field that indicates how many days were taken for leave.
Just at glance, it seems to me that your database was poorly designed. I think start date should have been included in the first place.

Hello .
I have a web service which takes some parameters and inserts them in another database . I have my own database that has a
table (Table_B) .Now
I want to call my web service when a new record inserts to (Table_B)
I know that i should use a trigger . All I want to do is calling a web service inside of my trigger . I don't know how to call it.
Would you please help me
Thanks .
bye

If I was you I would start here:
www.google.com[^]
Type sql server call web service from trigger and press Enter. That gives over 2 million links, at least one of them must be useful.
P.S. one of those links is to an article here on Code Project. In the article it actually says:
The truth is it's not good to access a web service trought a trigger, due to performance concerns.
I'm sure you can make your own mind up as to whether that is true or not.

Hi
Thanks for your Guidance. I know all of them but thanks

If I may ask, what inserts records in table_B; is it a stored procedure?
If so, I would use the same stored procedure to call the web service immediately after it inserts data. I don't know if ordinary stored procedures can call web services so I would suggest an extended stored procedure i.e. a CLR dll.
I haven't done anthing like it; so I am really just guessing.

I exported my results data into Excel 2007 (784,000 records on one column) so that I can Import it back into SQL Server 2008 as a table. When the data comes back from Excel it comes in as a float which I convert to a nvarchar(255) or varchar(50), but any record that has a letter in it shows up as NULL in SQL Server 2008. I have tried all combinations. Can anyone suggest anything?

Hi All,
Iam new to database. Here iam using sql server 2000. i want to sum the counts from two different tables. I need this to calculate the employees who have taken continuous leaves in a week/month.
Example: I have three table such as
Table1:tbl_attandence(it contains the employee id and the intimings and outtime)
Fields:empcode,intime,outime
Eg: EMP001,11/24/2011 09:30:45 AM,11/24/2011 04:30:15 PM
Table2:tbl_leaveentry(it contains the leave dates taken by an employee)
Fields:empcode,entrydate
Eg: EMP001,11/25/2011
Table3:tbl_holidays(it contains the list of holidays such as sunday,saturday,chrismas,newyear....)
Fields:holidays,days
Eg: 11/25/2011,sunday
I am attaching my code such that it return the sum but iam unable to return the employee name and id because it is showing the result as null as the holidays does not match
please help me in completion of process
select sum(counts)
from(
select a.empcode as empcode,b.name,count(*) as counts from tbl_leaveentry a,tbl_emp b
where a.empcode=b.empcode
and a.empcode='EMP001'
and a.entrydate between '11/24/2011'; and '11/27/2011'
group by a.empcode,b.name
union
select null,null,count(*) as counts from tbl_holidays
where holidays between '11/24/2011' and '11/27/2011'
) as c having sum(counts)>=3
the above code returns correct sum but if i add name before the sum and execute the result is not been summed because holidays does not match with the leaves
Please suggest that how can i do this task any help will be appreciated

Try something like:
select name, sum(counts)
from(
select a.empcode as empcode,b.name,count(*) as counts
from tbl_leaveentry a
INNER JOIN tbl_emp b
ON a.empcode=b.empcode
where a.empcode='EMP001'
and a.entrydate between '11/24/2011'; and '11/27/2011'
group by a.empcode, b.name
union
select null, null, count(*) as counts
from tbl_holidays
where holidays between '11/24/2011' and '11/27/2011'
) as c
GROUP BY name
having sum(counts)>=3
Note the GROUP BY and I have changed to an INNER JOIN.
Hope this helps. Sorry, I do not have time to dive deeper into this.

Try this.
DECLARE
@holidayCount AS int,
@startDate AS datetime,
@endData AS datetime,
@empCode AS VARCHAR(20)
SET @startDate='11/24/2011 00:00:00.000'
SET @endDate='11/27/2011 23:59:59.997'
SET @empCode='EMP001'
SET @holidayCount=(SELECT COUNT(*) FROM tbl_holidays WHERE
holidays BETWEEN @startDate AND @endDate)
SELECT empCode, name, (Counts + @holidayCount) As holidayCounts
FROM
(
SELECT a.empCode, b.name, (Count(*) as Counts
FROM tbl_leaveentry a,tbl_emp b
WHERE a.empCode=b.empCode AND
a.empCode=@empCode AND
a.entryDate @startDate and @endDate
GROUP BY by a.empCode,b.name
) AS temp
WHERE Counts + @holidayCount>3

Hi SilimSayo,

Hi everyone! How do I grant a server role permission to create users? I previously added database administrators to the 'sysadmin' server role and they were able to create users. I also changed the schema of my tables but now the schema for the 'sysadmin' role cannot be changed from 'dbo' to the one I created. One way to let them access tables is to prefix my tables with the schema name but there are lots and lots of code to do this.
I moved the administrators to the 'securityadmin' server role and they are able to use tables without prefixing table names with the schema name. But now they are only able to create logins but cannot create users as an error is reported that the user does not have permission to do it.
I would like to know how I can grant the 'securityadmin' role permission to create users so that I will not have to prefix my table names with the schema name if they should remain in the 'sysadmin' role as editing the code at this point for this will likely cause problems. Thanks in advance.

The type of the database (and the version) is essential when asking this level of information as the security functionality varies between database systems.
