Select Records From Two Tables, Plus Page And Order Them?

Feb 7, 2008

Hi,

I'm trying to look for an efficient way to select records from two tables, combine them (not just one set above the other) and also efficiently page the results as well as dynamically order by specific columns. So far I have this....

DECLARE @Temp TABLE
(
IDINTNOT NULL,
NameNVARCHAR(128)NOT NULL,
TypeCHAR(1)NOT NULL
)

INSERT INTO @Temp
SELECT i.ID, i.Name, Type = 'I' FROM Item i
UNION
SELECT p.ID, p.Name, Type = 'P'FROM Package p

SELECT * FROM @Temp
ORDER BY Name ASC

I was going to then implement some sort of of ROW_NUMBER like paging and ordering on the @Temp table variable. Problem is there could be potentially 1000's or more Items and Packages and they would all go in this single Temp table before having records 1 to 10 returned. Is there a more efficient way of doing this before I proceed any further?

Many thanks for any help! :)

Select Records By Order Of Insertion???

Jan 3, 2008



I need to create a temp table with an identity column based on the contents of a physical table (CONTACTS) that has no key or unique way to identify which record was inserted first,

I can query CONTACTS with no ORDER clause and everything is in the order it was inserted. However, when I create the temp table with a newid() as ID or IDENTITY(1,1) as ID, the duplicate rows as they existsed in the physical table are not inserted into the temp table in the same order.

Is it possible to select records from a physical table into a temp table in the same order while creating a unique field?

Here is how they exist in the physical table:

CLIENTID CHANGEDATE NEWVALUE

------------ ----------------------- ----------------------------------------------------------------

C0HTRA200005 2007-11-19 21:11:57.000 NULL

C0HTRA200005 2007-11-19 21:11:57.000 NULL

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

C0HTRA200005 2007-11-21 06:46:17.000 Acquisition

C0HTRA200005 2007-11-22 07:47:56.000 Acquisition

Here is how they exist after being inserted into the temp table using DISTINCT:

ID CLIENTID CHANGEDATE NEWVALUE

----------- ------------ ----------------------- ----------------------------------------------------------------

15 C0HTRA200005 2007-11-19 21:07:20.000 NULL

16 C0HTRA200005 2007-11-19 21:10:52.000 NULL

17 C0HTRA200005 2007-11-19 21:11:57.000 Acquisition

18 C0HTRA200005 2007-11-19 21:11:57.000 NULL

19 C0HTRA200005 2007-11-21 06:46:17.000 Acquisition

20 C0HTRA200005 2007-11-22 07:47:56.000 Acquisition


I've tried this many different ways using variations of ORDER BY/ no ORDER BY.
I've tried creating the temp table first with the IDENTITY field, then insert into it.
I've also tried SELECT INTO syntax while creating the IDENTITY field with the select. I've done this with newid() as well.

Any ideas would be huge.

Thanks much.

Order Of Records In The INSERTED/DELETED Tables In A Trigger

Nov 29, 2007

We have an app that uses triggers for auditing. Is there a way to know the order that the records were inserted or deleted? Or maybe a clearer question is.... Can the trigger figure out if it was invoked for a transaction that "inserted and then deleted" a record versus "deleted and then inserted" a record? The order of these is important to our auding.

Thanks!

Default Sort Order - Open Table - Select Without Order By

Mar 27, 2008

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.

yeah, you're right, it isn't totally clear: Quote: MS SQL Development forum discussing administration, MS SQL queries, and other MS SQL-related topics. i suppose "MS SQL" could be interpreted as "any product from microsoft that uses the sql language" but unfortunately what it really means is "microsoft sql server"

Specify Order For Select Results, Order By: Help!

Nov 17, 2006

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,

Zoop

INSERT-SELECT Depending On The Select:ed Order

Aug 15, 2006

I'm doing a INSERT...SELECT where I'm dependent on the records SELECT:ed to be in a certain order. This order is enforced through a clustered index on that table - I can see that they are in the proper order by doing just the SELECT part.

However, when I do the INSERT, it doesn't work (nothing is inserted) - can the order of the records from the SELECT part be changed internally on their way to the INSERT part, so to speak?

Actually - it is a view that I'm inserting into, and there's an instead-of-insert trigger on it that does the actual insertions into the base table. I've added a "PRINT" statement to the trigger code and there's just ONE record printed (there should be millions).

DTS -- Unpredictable Order Of Records -- Why?

Oct 9, 2006

Using bcp to load data from a flat file into a database table will load the records in the exact same order as they are in the flat file; whereas, a DTS package may not load the records into the table in the exact same order as they are in the flat file. Why? ... the table has no keys or indexes ... the DTS package was created with MS SQL 2000 and is now being used in MS SQL 2005 ...

T-SQL (SS2K8) :: Partition And Order Records

Oct 8, 2014

I have the below requirement:

1. Group records according to docno column.
2. Records will sort in desc order. (According to date1 column)
3. In date1 column if more than one date is same than we ll consider the date2 column.
EX: 2008-04-30 00:00:00is same here so sorting will happen based on Date2 column. So internal sorting should happen instead assigning random values.
4. Number column is the expected output column.

docnodate1 date2 Number
d1 2008-08-25 00:00:00 2009-09-08 11:23:41 1
d1 2008-04-30 00:00:00 2008-09-08 14:40:53 2

SQL Question ( Retrieving Records Based On A Priority Order )

Feb 24, 2008

Hi all,I have a table with this structure:Customer ID | Transaction date | Transaction type1 | 1/2/2008 | F1 | 1/4/2007 | M1 | 1/2/2008 | R2 | 1//5/2007 | M2 | 1/6/2007 | RFor each customer ID, I need to retrive only the records with the mostrecent transaction date, and I did:Customer ID | Transaction date | Transaction type1 | 1/2/2008 | F1 | 1/2/2008 | R2 | 1/6/2007 | RThe problem is, each customer can make more than one transaction inthe same day (see above). In these cases, I need to retrieve only onerecord per customer, based on the importance of the transaction: F ismore "important" than R which is more "important" than M. So, in theexample above, I would only retrieve transaction F for customer 1 anddisregard transaction R: they were made on the same date, but I ammore interested in F than in R.Do you have any suggestions on how I could achieve this in SQL?I use Microsoft SQL server 2005.Thank you for your help!

Shouldn't The Order Of Records Be Based On The Key Or Primary Index?

Jun 11, 2007

I upsized an access database with a key / index on ordernumber and linenumber.

However if I open the table in the Management Studio the records aren't ordered this way (same goes for select * from table) I get:










Ordernumber
Linenumber

200724001
37

200724004
3

200724006
33

200724001
3

200724011
19

200724014
5

200724006
37

200724011
19

200724006
28



Same goes for my crystal reports files, since the records aren't ordered by ordernumber / linenumber all my formulas go bezerk..



Am I wrong thinking the records should be ordered according to the prim. index?

Please help because I don't want to have to change all my 40+ reports to include an "ORDER BY"



Best regards,



Mike
