Cursor Processing Last Item In List Twice

Nov 7, 2002

Using the code below, my cursor processes the last record twice. I know it has to be something simple but I haven't been able to find it yet.
Please help.

select top 10 clientkey, max(id) As enrollmentkey
into #temptable1
from clientenrollment
group by clientkey


Declare Test_Cursor
Cursor for
select clientkey, enrollmentkey
from #temptable1
Open Test_Cursor

Declare @clientkey Char(10)
Declare @enrollmentkey Char(10)

FETCH NEXT FROM Test_Cursor
into @clientkey, @enrollmentkey
print @clientkey + ' ' + @enrollmentkey

WHILE @@FETCH_STATUS = 0

BEGIN


FETCH NEXT FROM Test_Cursor
into @clientkey, @enrollmentkey
print @clientkey + ' ' +@enrollmentkey

END
CLOSE Test_Cursor
DEALLOCATE Test_Cursor

If anyone has used this before and could point me in the right direction, I would appreciate it.

Retrieving Multiple Rows For A Cursor Item

Sep 28, 2000

Hi, can someone plz give me an idea of how to proceed with this...
I've got a server side cursor that retrieves a list of customers from a sql server table which match a specific criteria (those who have had orders in the yr 2000)
For each customer, I need to retrieve a list of 5 top items purchased along with dollars spent on each item by that customer.
I've tried to do this in a loop that uses a counter but probably my syntax was off and I'm not sure that this is better than a correlated join? Can someone show me a temlate of the appropriate syntax to use for this operation
I appreciate suggestions, thanks again.

write a query that lists item, mfg serial number, and inspection date. The caveat is that, where there is more than one record for an item, he only wants item listed once. For example:

Creating A Delimited List Of Data In SP W/O Cursor

Mar 29, 2001

SQL7 SP3

Hi.

I have a table in which I want to create a delimited list of values from one field which I will be using for validation.

How can I do this without using a cursor to build the string. The SQL would be something like:

SELECT *
FROM myCrossRefTable
WHERE SourceTable = 'FieldValueList'

I'm looking to return on string like -

~value1~value2~value3~value4~value5

Thanks,

Help, Running A Control Flow Item Does Not Kick Off The Next Item

Mar 6, 2007

Hi,

Here's my problem. I have 2 tasks defined in my Control Flow tab:

EXECUTE SQL--------->EXECUTE DTS 2000 PACKAGE

When I attempt to run it, by right-clicking the EXECUTE SQL task, and selecting "Execute Task", it only runs the EXECUTE SQL part (successfully), and does not "kick off" the EXECUTE DTS 2000 PACKAGE, after it is done running (even though it completes successfully, as shown by the green box).

Yes, they are connected by a dark green arrow, as indicated in my diagram above.

Why is this?? Am I missing something here? Need help.

THANKS

Finding Orders That Have At Least 1 Promo Item And 1 Non-promo Item

Oct 16, 2014

I am having trouble finishing the last bit of a report. The report shows orders that customers have placed that contain 0 promo items, All promo items (all items in order are promo items), and a mix of promo and non promo (at least 1 promo item and 1 non-promo item). Ive simplified this a bit for ease of understanding but lets assume we have 2 tables: A Promo table that contains the items on promotion and the dates that promotion is valid, and a Sales table, that contains the order number, order date, and sku ordered.

I've already written code that finds orders that have at least 1 promo item in them, and using that, I can determine what orders have 0 promo items in them. Where I am stuck is taking the orders that have at least 1 promo item in them, and separating them into orders that have only promo items, and those that have both promo and not promo items in them. Also, there are several promos throughout the year (called "Offers") so in my code below, you can see 2 different Offers ("JF" and "MA") with their corresponding dates they are valid. They will never overlap. My results also have to be split out by Offer so management can look at the results of each offer separately. Here is some code:

Code:
create table #Promos (
Offer varchar(2) null,
SKU int null,
StartDt date null,
EndDt date null

[Code] ....

So my results should show OrderNo A1111 in the Promo and No Promo group because of SKU 5 not being promotional during the time that order was placed. OrderNo A2222 should be in the Promo Only group because both SKUs on the order were promotional at the time the order was placed.

Transact SQL :: STATIC Defines A Cursor That Makes Temporary Copy Of Data To Be Used By Cursor

Aug 12, 2015

In MSDN file I read about static cursor

STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications

It say's that modifications is not allowed in the static cursor. I have a  questions regarding that

Static Cursor
declare ll cursor global static
            for select  name, salary from ag
  open ll
             fetch from ll
 
              while @@FETCH_STATUS=0
               fetch from ll
                update ag set salary=200 where 1=1
 
   close ll
deallocate ll

In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says  modifications is not allowed in the static cursor.But I am able to update the data using static cursor.

Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance

Jul 20, 2005

Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

SQL 2012 :: List All Different Values That Go With Single CAS ID To Appear As Comma Separate List

Jun 15, 2015

So at the moment, I don't have a function by the name CONCATENATE. What I like to do is to list all those different values that go with a single CASE_ID to appear as a a comma separate list. You might have a better way of doing without even writing a function

So the output would look like :

CASE_ID VARIABLE
=====================
1 [ABC],[HDR],[GHHHHH]
2 [ABCSS],[CCHDR],[XXGHHVVVHHH],[KKKJU],[KLK]

SELECT
preop.Case_ID,
dbo.Concatenate( '[' + CAST(preop.value_text AS VARCHAR) + ']' ) as variable
FROM
dbo.TBL_Preop preop
WHERE
preop.Deleted_CD = 0

GROUP BY
preop.Case_ID

Report Designer: Need To List Fields From Multiple Result Rows As Comma Seperated List (like A JOIN On Parameters)

Apr 9, 2008



I know I can do a JOIN(parameter, "some seperator") and it will build me a list/string of all the values in the multiselect parameter.

However, I want to do the same thing with all the occurances of a field in my result set (each row being an occurance).

For example say I have a form that is being printed which will pull in all the medications a patient is currently listed as having perscriptions for. I want to return all those values (say 8) and display them on a single line (or wrap onto additional lines as needed).

Something like:
List of current perscriptions: Allegra, Allegra-D, Clariton, Nasalcort, Sudafed, Zantac


How can I accomplish this?

I was playing with the list box, but that only lets me repeat on a new line, I couldn't find any way to get it to repeate side by side (repeat left to right instead of top to bottom). I played with the orientation options, but that really just lets me adjust how multiple columns are displayed as best I can tell.

Could a custom function of some sort be written to take all the values and spit them out one by one into a comma seperated string?

Items In List A That Don't Appear In List B (was Simple Query...I Think)

Jan 20, 2005

Ok, I want to write a stored procedure / query that says the following:
Code:
If any of the items in list 'A' also appear in list 'B' --return false
If none of the items in list 'A' appear in list 'B' --return true


In pseudo-SQL, I want to write a clause like this

Code:

IF
(SELECT values FROM tableA) IN(SELECT values FROM tableB)
Return False
ELSE
Return True


Unfortunately, it seems I can't do that unless my subquery before the 'IN' statement returns only one value. Needless to say, it returns a number of values.

I may have to achieve this with some kind of logical loop but I don't know how to do that.

Can anyone help?

Hi,

Here's a script. the creates the table,indexes, function and the storeproc. call the proc like procStoreAndUpdateTokenList 'word1,word2,word3'

My table is now 500000 rows and growing and I am inserting on average 300 words, some new some old.

performance is a not that great so I'm thinking that my code can be improved.

Get Item Name Instead Of ID

Jan 11, 2014

I´m trying to get a query where I´ll get an answer like this:

+--------------+----------------+----------------+------------------+-----------------+
| champion_id | champion_name | champion_item1 | champion_item... | champion_item16 |
+--------------+----------------+----------------+------------------+-----------------+
| 1 | Legolas | boots | ... | sword |
+--------------+----------------+----------------+------------------+-----------------+

This is the scenario how I set up my tables (let me know if I should change it):

table champions

+--------------+----------------+
|champion_id | champion_name |
+--------------+----------------+
| 1 | Legolas |
+--------------+----------------+

table equipment

+--------------+----------------+------------------+-----------------+
| champion_id | champion_item1 | champion_item... | champion_item16 |
+--------------+----------------+------------------+-----------------+
| 1 | 5 | ... | 22 |
+--------------+----------------+------------------+-----------------+

table items

+--------------+----------------+
| item_id | item_name |
+--------------+----------------+
| 5 | boots |
+--------------+----------------+
| 22 | sword |
+--------------+----------------+

But I still don´t know how to call the equipment table and get champion name and item names for the numbers. What did I do wrong and how can I fix it?

The foreign keys are in place.

ERROR: A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List.

May 22, 2006

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.

From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"

Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)

I "sometimes" get the following error:

OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.

Help would be appreciated!

I have seen other posts on this but, not able to relate the solution to my scenario.

Client Side Cursor Vs Sever Side Cursor?

Jul 20, 2005

I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim

How To Get The Last Item Added

Dec 14, 2004

Not 100% sure how to do this so I would appreciate some directions. I have 2 tables, Systems and Contacts. A system can have 1 to infinite contacts and contact can have 1 to infinite systems. So I use a 3rd table Sys_Con to add the contact needed for each system.
Now my question is once I add the System and contact how do I know for sure which ContactID to add in my Sys_Con table? Because while I am doing this operation maybe someone can add an other contact. So is there a way for my store proc Add_Contact to return the contactID needed for my store proc Add_Sys_Con ?

TABLE Sys_Con
SystemID int
ContactID int

Table Contact
ContactID int Identity
ContactName
...

Table System
SystemID
...

Get Only ONE Row Per Item With Different Fields

Nov 25, 2007

Hi,

I'm a bit stuck here.
I have a table called STM_COMM and it contains following fields: id, member_id, email_addr, tel_nr, fax_nr

A member can have multiple email addresses, telephone numbers and faxnumbers. so we could have something like this:

id member_id email_addr tel_nr fax_nr
-------------------------------------------------------
1 5 info@test.com
2 5 555687 568774
3 66 test@go.nl 65897854
4 5 another@one.com

What I would like to have is only ONE (1) row PER member with only the FIRST (not max!) entered known data. In the above case, I'd like to have this as result:

member_id email_addr tel_nr fax_nr
----------------------------------------------------
5 info@test.com 555687 568774
66 test@go.nl 65897854

I've tried lots of things (max, inner select ...) but I can't seem to figure it out.

Thank you for the help !

Christophe

PS: I'm working on a sql server 2005
