On top of my head, I can think of something like:

Select min(DOB) from UsersProfile where DOB > GetDate()

for getting persons, we can have:

Select Person from UsersProfile where DOB = 
     ( Select min(DOB) from UsersProfile where DOB > GetDate() )

Hope that helps.

Strange.. It works for me. Here are my test statements:

declare @UsersProfile table
(
  Person varchar(20),
  DOB datetime
)

insert into @UsersProfile
  select 'Person1', '2009-03-11'
  union select 'Person2', '2009-03-13'
  union select 'Person3', '2009-03-13'  
  union select 'Person4', '2009-03-16'
  union select 'Person5', '2009-03-25'

select * from @UsersProfile 
  where DOB = ( select min(DOB) from @UsersProfile where DOB>GetDate() )

Are you sure your DOB column is of DateTime type?

SELECT TOP 1 * FROM UsersProfile WHERE datepart(dy,DOB)>=datepart(dy,now()) ORDER BY datepart(dy,DOB)

is what I would try to get the next one.

Hi,

Since the first reply suggested something like

Select Person from UsersProfile where DOB = <br />
     ( Select min(DOB) from UsersProfile where DOB > GetDate() )

it must be rather easy to get it like so:

Select Person from UsersProfile where DOB =<br />
     ( whatever it takes to obtain the next birthday )

So I would try:

Select Person from UsersProfile where DOB =<br />
( SELECT min(datepart(dy,DOB)) FROM UsersProfile WHERE datepart(dy,DOB)>=datepart(dy, now()))

BTW: This is PHP/MySQL code that works for me:

$Query="SELECT * FROM $table WHERE DAYOFYEAR(birthday)= ".
    "(SELECT min(DAYOFYEAR(birthday)) FROM $table ".
    "WHERE DAYOFYEAR(birthday)>=DAYOFYEAR(now()))";

Sure I realise that, I am too, but the best way to learn isn't to get other people to do it for you. Like I said, Luc has offered a great deal of help here, more than enough for you to work out the rest.

If you still can't do it then post your code, I'm sure someone will be able to point you in the right direction.

Generate Reference Number

musefan11-Mar-09 0:06

11-Mar-09 0:06

Hi All,

Im creating an application in C# that needs to generate a partially-sequential value for a reference number which is stored in an SQL server database

the reference number will consist of three parts - a year value, a sequential number, and a system definded value

for example, 090001REF

then the next one generated would need to be 090002REF... 090003REF and so on

Ideally the sequence number would be reset at the start of a new year. 093245REF... 100001REF etc.

Can anyone offer a posible solution to how i would need to incorperate this functionality?

Can this be done within the database? or is this something i will need to handle throu my application? also i will need to keep in mind users creating a reference number at the same time, even if it is highly unlikely

Thanks for any suggestions Smile | :)

Life goes very fast. Tomorrow, today is already yesterday.

Hope this will help you

string refnum = "091222REF";//here you get last reference number from database<br />
            string newrefNum = "";<br />
            if (DateTime.Now.ToString("yy") != refnum.Substring(0, 2))<br />
            {<br />
                newrefNum = DateTime.Now.ToString("yy") + "0001REF";<br />
            }<br />
            else<br />
            {<br />
                int incNum = int.Parse(refnum.Substring(2, 4)) + 1;<br />
<br />
                newrefNum = DateTime.Now.ToString("yy") +  incNum.ToString("0000") + "REF";<br />
            }

Thanks for the reply, got me thinking in the right direction Smile | :)

i suppose some sort of TOP specification of 1 while ordering by created date and time would get the row i want.

Do you have any suggesion on how to avoid multiple users trying to add an entry at the same time thou?

What about just having the column as 'unique' then cathing the error and then trying the process again with an incremented reference?
Im not asking if it would be possible, as im sure it is, i just want to know if you can see any holes in the logic that i may have missed.

thanks again

1. You can make unique column of reference number and then in exception you insert new reference number.
example:

try<br />
{<br />
//insret refnumber<br />
}<br />
catch<br />
{<br />
//get last inserted number in table and then genereate new refnumber<br />
}<br />
finally<br />
{<br />
//close connection or do some else<br />
}

2. You can select last inserted refnumber and then generate new refnumber.
Example:

select top 1 refnumber from mytable order by id desc //ID column must be inc autonumber

string refnum = "091222REF";//here you have last inserted reference number in database<br />
string newrefNum = "";<br />
if (DateTime.Now.ToString("yy") != refnum.Substring(0, 2))<br />
{<br />
newrefNum = DateTime.Now.ToString("yy") + "0001REF";<br />
}<br />
else<br />
{<br />
int incNum = int.Parse(refnum.Substring(2, 4)) + 1;<br />
<br />
newrefNum = DateTime.Now.ToString("yy") + incNum.ToString("0000") + "REF";<br />
}

T-SQL and XML question.

Jamie Nordmeyer10-Mar-09 17:11

Jamie Nordmeyer

10-Mar-09 17:11

A website I'm writing uses jQuery and a plugin called Flexigrid, that expects an XML document in this format:

<rows>
   <page>1</page>
   <total>7</total>
   <row id="1">
      <cell>1</cell>
      <cell>SomeName</cell>
      <cell>SomeDescription</cell>
   </row>
   <row id="2">
      <cell>2</cell>
      <cell>SomeName</cell>
      <cell>SomeDescription</cell>
   </row>
</rows>

I managed to make it work with the following SQL:

Select
	1 As 'page'
	,7 As 'total'
	,(
		Select
			ID As '@id'
			,(Select ID As 'cell' From Table Where ID = dc.ID For Xml Path(''), Type)
			,(Select [Name] As 'cell' From Table Where ID = dc.ID For Xml Path(''), Type)
			,(Select [Description] As 'cell' From Table Where ID = dc.ID For Xml Path(''), Type, Elements XsiNil)
		From
			Table dc
		For Xml Path('row'), Type
	)
For Xml Path('rows'), Type

Is there a better way to do this? I've scoured Google, and wasn't able to find anything. This works, but it seems like there must be a better way that I'm just not finding.

Thanks.

I guess your table Student should contain column which have any value from Supervisor.
Your Student table have to looks like this :

StudentId StudentName  SupervisorId <br />
1         john          1<br />
2         paul          1<br />
3         britney       3<br />
4         Mike          5<br />
.<br />
.<br />
