Determine Next Order Id
May 17, 2007
I'm working on a sproc that determines the next order id for a specified customer. The table has
custid int,
ordernum varchar(10)
Data is:
1000, 1000-001
1000, 1000-002
1001, 1001-001
1000, 1000-003
I need to know the next ordernum for the specified custid. For example, GetNextOrderNum(1000) should return 1000-004. GetNextOrderNum(1002) should return 1002-001 (since there aren't any orders yet).
I honestly don't know where to begin.
Can someone please help?

I am trying to determine the next available order id using the method below. It works provided the table has a record in it. If it doesn't I get the error "Input string was not in a correct format." I am certain that it is because the query is returning a value of NULL. How can get around that or check for the NULL value?' Establish data connection...Dim sqlConn As New SqlConnection(ConfigurationSettings.AppSettings("connectionstring"))'Determine order id number...Dim order_id As IntegerDim strSQL As StringstrSQL = "Select MAX(order_id) from mkt_order"Dim sqlCmd As New SqlCommand(strSQL, sqlConn)Dim sqlDA As New SqlDataAdapter(sqlCmd)Dim sqlDS As New DataSetsqlDA.Fill(sqlDS, "item")If sqlDS.Tables(0).Rows.Count <> 0 Thenorder_id = Convert.ToInt32(sqlDS.Tables(0).Rows(0)(0).ToString()) + 1Elseorder_id = 1End If

Hi.
I have a VB.NET function that returns an array of Integers.
Say, FunArray = [2, 3, 5, 8, 6, 23, 1, 10, 20 , 4, 54]
One characteristic of the array is that no two numbers
repeat - it reflects the IDs of my Users table. And, that
it is not ascending or descending.
What I would like to know is how do I sort my query in
the order of the integers in this array? Ideally, I
would like to use ORDER BY for this query.
thanks in advance.

Does anyone have a script that analyzes primary and foreign key relationships of tables and produces a suggested load order based upon dependancies?
Thanks,

I am trying to order by the field and direction as provided by input parameters @COLTOSORTBY and @DIR while using a CTE and assigning Row_Number, but am running into syntax errors.
Say I have a table called myTable with columns col1,col2,col3,
Here's what I'm trying to do
with myCTE AS
(
Select
col1
,col2
,col3
,row_number() over (order by
case when(@DIR = 'ASC') then
case when @COLTOSORTBY='col1' then col1 asc
when @COLTOSORTBY='col2' then col2 asc
else col3 asc
end
else
case when @COLTOSORTBY='col1' then col1 desc
when @COLTOSORTBY='col2' then col2 desc
else col3 desc
end
end
from myTable
)
Please let me know what i can do with minimal code repetition and achive my goal of dynamically sorting column and direction. I do not want to use dynamic SQL under any circumstance.
Thanks.

Finding the "pieces of information" I need to successfully install the SQL Server Express edition is so complex. Uninstalls do "not" really uninstall completely, leading to failure of SQL install. Can you suggest a thorough, one-stop site for directions for the order of app uninstalls and then the order for app installs for the following...
SQL Server Express edition
Visual Studios 2005
Jet 4.0 newest upgrade
.Net Framework 2.0 (or should I use 3.0)
VS2005 Security upgrade
Anything else I need for just creating a database for my VS2005 Visual Basic project?
I was trying to use MS Access as my backend db but would like to try SQL Express
Thank you, Mark

In SQL sERVER 2008, I have two fields - Depatment and Employees. I need to sort the result set by employee number ascending order, with following exception
1)when department number = 50 - the preferred order is Employee # - 573 followed by 551-572 (employee # belong to Dept 50 = 551-573)
2)When Department number = 20 – the preferred sort order is Employee # 213-220, followed by Employee # 201-213 (employee # belong to Dept 20 = 201-220)
How shall I achieve this?

I never paid much attention to this before but I noticed this today in a new table I was creating.
For tables defined in the tabular model the table properties have something like SELECT Blah FROM TableName ORDER BY Blah Then in the tabular model the table's data is in the same order it was ordered by in the data source for the table.
I have a date table I setup and I noticed it is NOT respecting the sort order.
I have it sorted by DateID which sorts with the oldest date first and newest date as last row.However, the table that is imported and stored in the data model is not in that order.
I can of course manually sort the rows in BIDS/DataTools, but I find this discrepancy odd.
Would this have negative impacts on the EARLIER function for example if the data rows are not in the order specified?

I have a query that calculate the total amount of order details based on a particular order:
Select a.OrderID,SUM(UnitPrice*Quantity-Discount)
From [Order Details]
Inner Join Orders a
On a.OrderID=[Order Details].OrderID
Group by a.OrderID
My question is what if I wanted to create a formula to something like:
UnitPrice * Quantity - DiscountAmount Where DiscountAmount = UnitPrice Quantity * Discount
Do I need to create a function for that? Also is it possible to have m y query as a table variable?

Hi!
I recently run into a senario when a procedure quiered a table without a order by clause. Luckily it retrived data in the prefered order.
The table returns the data in the same order in SQL Manager "Open Table"
So I started to wonder what deterimins the sort order when there is no order by clause ?
I researched this for a bit but found no straight answers. My table has no PK, but an identiy column.
Peace.

Hi,
We got a problem.
supposing we have a table like this:
CREATE TABLE a (
aId int IDENTITY(1,1) NOT NULL,
aName string2 NOT NULL
)
go
ALTER TABLE a ADD
CONSTRAINT PK_a PRIMARY KEY CLUSTERED (aId)
go
insert into a values ('bank of abcde');
insert into a values ('bank of abcde');
...
... (20 times)
select top 5 * from a order by aName
Result is:
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
select top 10 * from a order by aName
Result is:
11Bank of abcde
10Bank of abcde
9Bank of abcde
8Bank of abcde
7Bank of abcde
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
According to this result, user see the first 5 records with id 6, 5, 4, 3, 2 in page 1, but when he tries to view page 2, he still see the records with id 6, 5, 4, 3, 2. This is not correct for users. :eek:
Of course we can add order by aid also, but there are tons of sqls like this, we can't update our application in one shot.
So I ask for your advice here, is there any settings can tell the db use default sort order when the order by column value are the same? Or is there any other solution to resolve this problem in one shot?

I have created view by jaoining two table and have order by clause.
The sql generated is as follows
SELECT TOP (100) PERCENT dbo.UWYearDetail.*, dbo.UWYearGroup.*
FROM dbo.UWYearDetail INNER JOIN
dbo.UWYearGroup ON dbo.UWYearDetail.UWYearGroupId = dbo.UWYearGroup.UWYearGroupId
ORDER BY dbo.UWYearDetail.PlanVersionId, dbo.UWYearGroup.UWFinancialPlanSegmentId, dbo.UWYearGroup.UWYear, dbo.UWYearGroup.MandDFlag,
dbo.UWYearGroup.EarningsMethod, dbo.UWYearGroup.EffectiveMonth
If I run sql the results are displayed in proper order but the view only order by first item in order by clause.
Has somebody experience same thing? How to fix this issue?

I am getting the resultset sorted differently if I use a column number in the ORDER BY clause instead of a column name.
Product: Microsoft SQL Server Express Edition
Version: 9.00.1399.06
Server Collation: SQL_Latin1_General_CP1_CI_AS
for example,
create table test_sort
( description varchar(75) );
insert into test_sort values('Non-A');
insert into test_sort values('Non-O');
insert into test_sort values('Noni');
insert into test_sort values('Nons');
then execute the following selects:
select
*
from
test_sort
order by
cast( 1 as nvarchar(75));
select
*
from
test_sort
order by
cast( description as nvarchar(75));
Resultset1
----------
Non-A
Non-O
Noni
Nons
Resultset2
----------
Non-A
Noni
Non-O
Nons
Any ideas?

I noticed the StockDate is not sorted in proper order, like ascending order...
Code:
select top 1000 CONVERT(char, StockDate, 101) AS StockDate, timestamp from tblpurchaseraw where accountid = '119' order by stockdate desc
I noticed that StockDate is a datetime datatype so why does the month get ordered 1st, then day get ordered 2nd and year get ordered 3rd...
The sample data is MM/DD/YYYY...
So, how do I get it ordered propery by Year, Month then Day??

Lets say I have a table named [Leadership] and I want to select the field 'leadershipName' from the [Leadership] Table.
My query would look something like this:
Select leadershipName
From Leadership
Now, I would like to order the results of this query... but I don't want to simply order them by ASC or DESC. Instead, I need to order them as follows:
Executive Board Members, Delegates, Grievance Chairs, and Negotiators
My question: Can this be done through MS SQL or do I need to add a field to my [Leadership] table named 'leadershipImportance' or something as an integer to denote the level of importance of the position so that I can order on that value ASC or DESC?
Thanks,

Hi,
I have some hierarchical data in a table. Say for example:
Parent Child
------------------------
NULL 1
1 2
1 3
2 4
2 5
3 6
3 7
5 8
5 9
7 10
7 11
11 12
11 13
Now I want to be able to use CTE's to be able to traverse this tree in
1) level by level order 1,2,3,4,5,6,7,8,9,10....
2) in order 1,2,4,5,8,9,3,6,7,10,11,12,13...
What would be the aueries for this. Using the following i get: 1,2,3,6,7,10,11,12,13,4,5,8,9 (interesting and potentially useful) but I would like to be able to experiment with the aforementioned orders as well.
with Tree (id)
as
(
select id from WithTest
where parent is null
union all
select a.id
from Tree b join WithTest a
on b.id = a.parent
)
select * from Tree
Any ideas? Thanks.

Hi!
For the Orders table (let's assume for the Northwind database), I'm trying
to get the order id of the latest order for every customer.
That means that the result should be one record per customer and that would
display CustomerID and OrderID.
Any ideas?

Good day,
We have a web application (ASP) running on SQL Server 7.0.
Recently, the users are getting quite a lot of timeouts on
the database:
Microsoft OLE DB Provider for ODBC Drivers error '80040e31'
[Microsoft][ODBC SQL Server Driver]Timeout expired
The database is not supposed to be doing too much work, so I can't
understand why these timeouts are occuring. How can I determine
the cause of the timeouts?
The cause could probably anything from a trigger that's taking
too long, a query that's taking too long, or simply bad database design.
I've looked at SQL Server's Profiler, but could not yet use it
successfully to give me any hints of what could cause the timeouts.
Any ideas of how I can use Profiler, Performance Monitor, or any other
tool(s) to see what is happening in the background in the database,
i.e. how much processing a trigger is using, etc.
Thanks very much!

I'm new to full text catalogs and we have a vendor who's code utilizes them. The database server is SQL 2005 and I am noticing the following message in the SQL log every minute.
Changing the status to MERGE for full-text catalog "ResearchCatalog" (5) in database "DBA_Test" (11). This is an informational message only. No user action is required.
A SQL job is running the following command every minute.
exec sp_fulltext_catalog 'ResearchCatalog', 'start_incremental'
What is the typical frequency for running an incremental?
Can the messages be suppressed?
Thanks, Dave

I've been doing a lot of reading on this and my head is starting tohurt! It seems to be quite a feat to work out how much memory isactually being used by our server.I'm running W2K advanced server with SQL 2000 EE, 8GB of RAM, a min of4GB and a max of 6GB is assigned to SQL server.I'm trying to work out whether we've assigned enough or toomuch/little memory to SQL server. My first thought was to let SQLdymanically manage its own memory and see how much it uses, of coursewhen AWE (/3GB /PAE) is enabled it will just use all that isavailable.In perfmon "target server memory" = 6.1GB, "total server memory" =6.1GB, "total pages" = 768000 ( x 8KB = 6.1GB).My second thought was to use "total pages" - the average "free pages"= average mem used, therefore giving me the average amount of memoryused by SQL. I found out that SQL uses a min of 4GB (the min weassigned) and the max of all the memory, 6GB.Is there an easier way of finding out how much memory is actually usedin this situation or is going by the above average the best way?What i'm unsure about is will SQL just use all memory assigned to ituntil it has the whole DB in memory? 20GB including indexes etc....Any help would be greatly apprechiated.

Hi all... This is the definition on the M/S site:
"Deterministic functions always return the same result any time they are called with a specific set of input values and given the same state of the database. Nondeterministic functions may return different results each time they are called with a specific set of input values even if the database state that they access remains the same."
Good... straight forward, right? Ok.... try entering thses command seperately:
Create Table Readings (ReadingDate DateTime Not Null);
Create Function [dbo].[funct_SameDate](@datReadingDate Datetime)
Returns DateTime
As
Begin
return @datReadingDate;
End
Alter table Readings add
[TempColumn] as (dbo.[funct_SameDate](ReadingDate)) PERSISTED NOT NULL;
Error on last command returns:
Computed column 'TempColumn' in table 'Readings' cannot be persisted because the column is non-deterministic.
Can someone please explain this to me? The same value is always being returned.
This does work:
Create Table Readings (ReadingDate DateTime Not Null);
Alter table Readings add [TempColumn] as (ReadingDate) PERSISTED NOT NULL;
I obviously want to do more things inside the function, but I can't get by the first step.
Any suggestions?
Thanks!

Hi,
I have a report that has a table with detail grouping. This table shows the sales by day for each product. The users only want to see the date field for the first item in the group. After that, they do not want to display this field (to reduce the data on the report). However, when the data wraps to a second page, they want the date to appear on the first row of the new page.
Is there any way to determine if a row is the first row on a page?
I tried using the RowCount, but that continues from the previous page.
Any thoughts?
Thanks!
David.
