Sorting Cursor Output WITHOUT Using Order By
Mar 1, 2004
Hi,
I have a situation where I need to sort the output of a cursor. But since the sort criteria are rather complex, I am NOT able to use the Order By clause directly with the cursor definition statement.
Hence, I need to have a solution where I will use a dummy (calculated) field within the CURSOR and I want the output of this cursor sorted by the dummy field that I calculated within the cursor itself.
Please let me know the different possibilities in this scenario.
Thank you in advance
Raj

I have a problem with an Order By sort on a SubmissionDate column in my SQLSERVER DB.
I am inputing a timestamp in this format into the column above: 1/18/2005 11:03:19 AM
Problem is, once I sort this column in DESC order to return the results to a datalist dates with a time like this:
1/18/2005 1:03:19 AM
get placed out of place (lower on the return in DESC/higher on the return in ASC). I am assuming this is happening because it reads 1 as coming before 11 instead of after like it is with time. If this was in 24 hour format this wouldn't be a problem I guess because 1PM would be 13, so that is after 11.
Anyone know what I can do to get this sorted correctly?

Hi, I've created a website usiing asp.net and all the data are stored in sql front. All the item are sorted in ascending order except one record. The correct order should be MP61, MP100, MP200, but this record is retrieved as MP100, MP200, MP61. If the coding is wrong, all the order displayed is not in ascending order. We have hundreds of items, but why it happens to this particular record? Can anyone help? Thanks in advance

I am trying to sort this simplied table:
ID - Time
1 2000-2001
2 2002-
3 2001-2003
4 1999
5 2005-2006
I want this as a result:
1999
2000-2001
2001-2003
2005-2006
2002-
Because the "-" means "continues", it the thing is still activated, so if it makes it easier, i could put the today's year afterwards during the query, if it ends with a - ...
Now, simply doing a
SELECT * FROM [table] ORDER BY TIME;
Sorts it "perfectly", apart from the "2002-" is just placed before 2005 and after 2001.
So, of course, it fails on all entries with a leading "-" ...
Right when I clicked "submit", of course, I can simply replace all entries with a time ending with "-", with the todays Year, so at least they will get at the end of the query...
Well, have to do a union, first sorting all without the "-", then sorting all with the "-", and that should be it...

I noticed that I cannot use ORDER BY in cursor, but in my case I need to order data in cursor.
I'm thinking about selecting data for cursor from temp table where data is ordered but may be there are other decisions to get data in cursor ordered?

Hi,
when I create a stored procedure with cursor, I got this problem: if I have ORDER BY in the code, I got below error message. It change to OK once I remove the ORDER BY.I tried to run the SELECT with ORDER BY in seperated statement, works just fine.I cannot understand what the error message mean, either google found nothing. What's the problem, or how I debug out the reason. Thank you very much.
here is the code:

set QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[SP_Lookup_A]
(
@projId varchar(10)
)
AS
BEGIN

DECLARE rsLotnos CURSOR FOR

Another question for all you SQL experts, I have a lot of them. I am trying to select from a table wher some conditions need to be met based on an employee ID. What I am doing is when the rank is a 1,2, or 3 I pick up the text description of that rank. Can I make it so that I get the ID only once and all the text descriptions are on the same line.

I'm using a cursor in SQL Server 2000 to assist me in calculating for each store, the Sales Rank of a zip code. There are about 1500 stores, and 125,000 store/sales/zip code records.
I am finding that this works for about 95% of the stores, but about 5% are getting fouled up, where the store's records are getting split in the sequencing, and so the store ends up with two zips ranked 1, two ranked 2, two ranked 3, etc.
In the DB structure, there is a constraint restricting one record per store (org_id) per zip code (postalcode).
Here's my code. Basically what I'm trying to have the cursor do is go through the table, ordered by org_id (store) asc, org_criteria_value (sales) desc, and rank the zip codes. When a new store is encountered, reset the counter to 1 and start ranking again. Do this until all the records are processed.
/*CREATE Sales_Table table */
CREATE TABLE [dbo].[Sales_Table] (
[count_id] [int] NULL ,
[org_id] [int] NULL ,
[postalcode] [varchar] (20) NULL,
[sales] [numeric](18,6) NULL ,
[sales_rank] [integer] NULL,
[org_criteria_input_date] [datetime] NULL
) ON [PRIMARY]
insert into Sales_Table
select 0 as count_id, omd.org_id, omd.postalcode, omd.org_criteria_value, 0 as cum_rank, org_criteria_input_date
fromorg_model_data omd
join org o on o.org_id = omd.org_id
where o.client_id = @ClientID
and model_Criteria_id = 27
and org_criteria_value <> 0
order by omd.org_id asc, omd.org_criteria_value desc
-- DECLARE CURSOR for Sales_Table
declare SalesRankCursor CURSOR
SCROLL dynamic FOR
select org_id, sales, sales_rank
from Sales_Table
for update of sales_rank
-- CREATE LOOP TO UPDATE SALES RANK in Sales_Table with valid values
OPEN SalesRankCursor
while exists (Select * from Sales_Table where sales_rank = 0)
Begin
FETCH NEXT FROM SalesRankCursor
set @StoreNext = @StoreCurrent
set @SalesRank = (@SalesRank + 1)
update Sales_Table
set@StoreCurrent = org_id
where current of SalesRankCursor
if @StoreCurrent <> @StoreNext
begin
set @SalesRank = 1
end
update Sales_Table
setsales_rank = @SalesRank
where current of SalesRankCursor
End
CLOSE SalesRankCursor
DEALLOCATE SalesRankCursor
Any ideas?

Has anyone ever tried to use a cursor as an output variable to a stored proc ?
I have the following stored proc - CREATE PROCEDURE dbo.myStoredProc
@parentId integer,
@outputCursor CURSOR VARYING OUTPUT
AS
BEGIN TRAN T1
DECLARE parent_cursor CURSOR STATIC
FOR
SELECT parentTable.childId, parentTable. parentValue
FROM parentTable
WHERE parentTable.parentId = @parentId
OPEN parent_cursor
SET @outputCursor = parent_cursor
DECLARE @childId int
DECLARE @parentValue varchar(50)
FETCH NEXT FROM parent_cursor INTO @childId, @parentValue
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT childTable.childValue
FROM childTable
WHERE childTable.childId = @childId
FETCH NEXT FROM parent_cursor INTO @childId, @parentValue
END
CLOSE parent_cursor
DEALLOCATE parent_cursor
COMMIT TRAN T1
GOAnd, I found that I had to use a cursor as an output variable because, although the stored proc returns a separate result set for each returned row in the first SQL statement, it did not return the result set for the first SQL statement itself.
My real problem at the moment though is that I can't figure a way to get at this output variable with VB.NET.Dim da as New SqlDataAdapter()
da.SelectCommand = New SqlCommand("myStoredProc", conn)
da.SelectCommand.CommandType = CommandType.StoredProcedure
Dim paramParentId as SqlParameter = da.SelectCommand.Parameters.Add("@parentId", SqlDbType.Int)
paramParentId.Value = 1
Dim paramCursor as SqlParameter = daThread.SelectCommand.Parameters.Add("@outputCursor")
paramCursor.Direction = ParameterDirection.OutputThere is no SqlDataType for cursor. I tried without specifying a data type but it didn't work. Any ideas?
Thanks

Hi!I have a database (Sql) which has a table in it named news_tbl, within this table I have a column called newsDate which is filled with a timestamp in the format dd/mm/yyyy 00:00:00. The date shows when the news item was created but the time is not used hence the reason its always 00:00:00.
I have an archive page which allows the user to view the news articles by the month they were posted. I have an SQL statement just which looks like this:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:news2007aConnectionString %>"
SelectCommand="Select Distinct LEFT(DATENAME(month, newsDate), 3) As TheMonth, DateName(month,newsDate) As TheFullMonth, DateName(year,newsDate) As TheYear, DatePart(month, newsDate) As TheOrder From news_tbl Order By TheMonth ASC, TheOrder DESC">
</asp:SqlDataSource>
and the output just now is
April 2008
December 2007
February 2008
January 2008
March 2008
November 2007
October 2007
September 2007
I would like the output to be the latest month first i.e. April 2008 then March 2008 then February 2008 and so on. I have tried a couple of different SQL statements but can't get the output to appear in the order I want.
Can anyone suggest where I am going wrong. Thanks,
O.

The stored procedure, below, results in this error when I try to compile...
Msg 156, Level 15, State 1, Procedure InsertImportedReportData, Line 69
Incorrect syntax near the keyword 'ORDER'.
However the select statement itself runs perfectly well as a query, no errors.
The T-SQL manual says you can't use the keywords COMPUTE, COMPUTE BY, FOR BROWSE, and INTO in a cursor select statement, but nothing about plain old ORDER BYs.
What gives with this?

My server is MS Sql Server 2005. I'm using com.microsoft.sqlserver.jdbc.SQLServerDriver as the driver class. I've established a connection to the database.
I'm trying to invoke a stored procedure using JDBC and a callable statement. The stored procedure has a parameter @CurOut CURSOR VARYING OUTPUT. How do I setup the callable statement so the output parameter is accepted by the driver?
I'm not really trying to pass a cursor up to the database Server but I'm wanting a cursor back from the stored procedure that is other than the result set or other value the stored procedure returns.
First problem: What java.sql.Types (or SQL Server specific) value do I specify for the out parameter I'm registering on the CallableStatement?
Second problem: What do I set the value of the parameter to?
The code looks like:
CallableStatement cstmt = myConnection.prepareCall(sQuery);
cstmt.registerOutParameter(1, Types.OTHER); // What is the right type?
cstmt.setNull(1, Types.OTHER); // What is the right type?
if (cstmt.execute()) {
ResultSet rs = cstmt.getResultSet();
}
Execution results in a NullPointerException from the driver.
What am I doing wrong?
Thanks for your assistance.

Hi -
I have a SSIS package that dumps data from an internal table to a flat file output using standard data flow tasks. The entire table is output - no special SQL. Most of the time the records are placed in the output file in the same order as the internal DB table, but occasionally the order appears to be more random. When that happens, the record order in the internal table is correct - it is just the output.
I can find no properties that seem to affect this. I would appreciate any hints and advice that anyone can give me. Has anyone else encountered this same problem?
Thanks in advance,
Jim Sweeney

I have a report where I am giving the users a parameter so that they can select which field they would like to sort on.The report is also grouping by that field. I have a gruping section, where i have added code to group on the field I want based on this parameter, however I also would like to changing the sorting order but I checked around and I did not find any info.
So here is my example. I am showing sales order info.The user can sort and group by SalesPerson or Customer. Right now, I have code on my dataset to sort by SalesPerson Code and Order No.So far the grouping workds, however the sorting does not.
Any suggestions would help.

SSRS 2012 - VS2010...The report compares two years with a sort order on a value that has been engineered based on text switched to int. When sorting A-Z this is the result in the horizontal axis is: 5th, K, 1st, 2nd, 3rd, 4th, 5th..When sorting Z-A the result in the horizontal axis is:5th, 4th, 3rd, 2nd, 1st, PreK..Z-A is correct but A-Z sorting shows 5th as the start and end. The magnitude of the PreK location is correct but the label is wrong on the A-Z sort order. The sorting is implemented using the Category Group sorting option.

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.

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

declare @retval int
if (@precommand is not null) EXECUTE(@precommand)
/* Create the select */
EXECUTE(N'declare hCForEachTable cursor global for

select @retval = @@error
if (@retval = 0)
EXECUTE @retval = [dbo].sp_MSforeach_worker @command1, @replacechar, @command2, @command3, 0
if (@retval = 0 and @postcommand is not null)
EXECUTE(@postcommand)
RETURN @retval

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?
