How To Write SQL Query And Not Cursor ?

Oct 10, 2004

Please help me to get the required result:
For each IDS in table1
- change the ids to numbers (eg. for '1,2,3' get the numbers (IntValue) 1, 2 & 3)
- in table2, find the maxVal for each number
- disply the table1..ids, number, table2..maxVal & table1..idsDesc,
order by table1..ids, table2..maxVal & IntValue

I have 2 tables, over milin records each. The Simplified versions of the tables looks like that:

create table table1 (ids varchar(100), idsDesc varchar(100))
go
insert table1 select '1,2,3', 'Description 1'
union all select '2,3,4', 'Description 2'
union all select '1,7', 'Description 3'
union all select '16,3,8', 'Description 4'
union all select '2,5,6,1', 'Description 5'
go

create table table2 (ids int, maxVal int)
go
insert table2 select 1, 10
union all select 2, 6
union all select 3, 12
union all select 4, 11
union all select 5, 66
union all select 6, 4
union all select 7, 3
-- union all select 8, 5 -- no value for 8
union all select 9, 6
union all select 16, 12
go

I have also function that returns table variable of numbers delivered from given string:
create function dbo.fn_StrToIntValues ( @str varchar(1000) )
returns @numsTbl table (IntValue int not null)

The command
select * from dbo.fn_StrToIntValues('1,2,33')

Returns --> intValue
1
2
33

Can I use SQL query and not cursor to get the following result ?

Required Output :
ids IntValue maxVal idsDesc
--------- -------- ------- ---------------
'2,5,6,1' 5 66 'Description 5'
'16,3,8' 16 12 'Description 4'
'2,3,4,9' 3 12 'Description 2'
'1,2,3' 3 12 'Description 1'
'1,7' 1 10 'Description 3'

Query Results Couble Spaced When Using Cursor

Feb 8, 2001

Just upgraded from 6.5 to 7 and in query analyzer I get double spaced results on queries that previously single-spaced. Installed 2000 QA and still get same results. Is there a setting that we are missing or a workaround to this?

Note ==> The cursor query returns single spaced results when ran alone.

Test code below:

DECLARE @pol char(10)
DECLARE testcursor CURSOR FOR
SELECT policy_no FROM policy_history
WHERE policy_chg_end_dt is null and policy_deleted_sw = 0

OPEN testcursor
FETCH NEXT FROM testcursor INTO @pol

WHILE @@FETCH_STATUS <> -1
BEGIN
SELECT @pol
FETCH NEXT FROM testcursor INTO @pol
END

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.

Cursor Works In Query Analyzer But Not In Stored Procedure

Mar 7, 2008



Hi i have a script works in sql query analyzer;


declare @id decimal


declare mycur CURSOR SCROLL for select myRowID from myTable order by myRowID
open mycur;

Fetch ABSOLUTE 30 from mycur into @id
close mycur;
deallocate mycur;

select @id
this script turns me a value.

i create a stored procedure from above script and its syntax is ok;
CREATE PROCEDURE SELECT_MyRow
AS
declare @cur cursor
declare @RowID decimal
set @cur = CURSOR SCROLL
for select myRowID from myTable order by myRowID
open @cur
Fetch ABSOLUTE 30 from @cur into @RowID
close @cur
deallocate @cur
select @RowID
GO

my c# code using stored procedure is below;






Code Snippet
try
{

OleDbCommand cmd = new OleDbCommand("SELECT_MyRow", myconnection);
cmd.CommandType = CommandType.StoredProcedure;
myconnection.Open();
OleDbDataReader reader = cmd.ExecuteReader();
MessageBox.Show(reader.GetName(0));//here fails
while (reader.Read())
{

MessageBox.Show(reader.GetDecimal(0).ToString());
}
reader.Close();
myconnection.Close();
}
catch(Exception ex)
{

MessageBox.Show(ex.Message);
}


The code above fails because reader reads no values, error message is "No data exists for the row/column"
but i know exists. Can anyone help me, what is the difference between stored procedure and script ?

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 Server 2012 :: Cursor Stop Query At Specific Time?

This store procedure will get some executable queries from the select statement, the cursor will fetch each rows to execute the query and insert the queries into table_3 to mark as 'E'. Until 17:00, this store procedure will stop execute the queries and just get the queries from select statement insert into table_3 to mark as 'C'.

I don't know why the outputs in table_3 are quiet different than I think. This store procedure comes out with two exactly same queries and one marked as C and another marked as E.

Dynamic Query, Local Cursor Variable And Global Cursors

Oct 3, 2006

Hi all.



I am stuck in a bit of a conundrum for quite a while now, and I hope someone here will help me figure this one out.



So, first things first: let me explain what I need to do. I am
designing a web application that will allow users to consult info
available in a SQL2000 database. The user will enter the search
criterea, and hopefully the web page will show matching results.



The problem is the results shown aren't available per se in the DB, I
need to process the data a bit. I decided to do so on the SQL Server
side, though the use of cursors. So, when a user defines his search
criteria, I run a stored procedure that begins by building a dynamic
sql query and creating a cursor for it. I used a global cursor in order
to do so. It looked something like this:



SET @sqlQuery = ... (build the dinamic sql query)

SET @cursorQuery = 'DECLARE myCursor CURSOR GLOBAL FAST_FORWARD FOR ' + @sqlQuery

EXEC @cursorQuery

OPEN myCursor

FETCH NEXT FROM myCursor INTO ...

CLOSE myCursor

DEALLOCATE myCursor



This works fine, if there's only one instance of the
stored procedure running at a time. Should another user connect to the
site and run a search while someone's at it, it'll fail due to the
atempt to create a cursor with the same name.



My first thought was to make the cursor name unique, which led me to:

...

SET @cursorName = 'myCursor' + @uniqueUserID

SET @cursorQuery = 'DECLARE '+ @cursorName + 'CURSOR FAST_FORWARD FOR ' + @sqlQuery

EXEC @cursorQuery

...



The problem with this is that I can't do a FETCH NEXT FROM @cursorName since
@cursorName is a char variable holding the cursor name, and not a
cursor variable. So to enforce this unique name method the only option
I have is to keep creating dynamic sql queries and exucting them. And
this makes the sp a bitch to develop and maintain, and I'm guessing it
doesn't make it very performant.



So I moved on to my second idea: local cursor variables. The problem with
this is that if I create a local cursor variable by executing a dynamic
query, I can't extract it from the EXEC (or sp_executesql) context, as
it offers no output variable.


I guess my concrete questions are:


Is it possible to execute a dynamic sql query and extract a (cursor) variable from it?Is it possible to populate a local cursor variable with a global cursor, by providing the global cursor's name?Can I create a local cursor variable for a dynamic sql query? How?



Anybody sees another way arround this?Thanks in advance,

Carlos

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

Need Help With A Cursor

Jul 25, 2006

I hope this is the appropriate forum for this question, if not then I apologize.
I've got a SQL Server 2000 stored procedure that returns data to be used in a crystal report in Visual Studio 2005.  Most of the stored procedure works well, but there is a point where I need to calculate an average number of days been a group of date pairs. 
I'm not familiar with cursors, but I think that I will need to use one to achieve the result I am looking for so I came up with the code below which is a snippet from my stored procedure.  In this part of the code, the sp looks at the temporary table #lmreport (which holds all of the data that is returned at the end to crystal) and for every row in the table where the terrid is 'T' (the territory is domestic), it selects all of those territories from the territory table and loops through them to determine the date averages (by calling a nested stored procedure, also included below) for each territory and then updates #lmreport with that data.
When I try to run the stored procedure, I get "The column prefix '#lmreport' does not match with a table name or alias name used in the query." on the line indicated. 
Does anyone have any idea what might be wrong or if this will even work the way I need it to?
Thank you in advance.

Need Cursor Help

Apr 4, 2006

Hello, I'm trying to construct a cursor that will sequentually increment a number and then update a column with the incremented number. My propblem is that all the rows in the table are being updated with the base number +1. So all rows are updated with 278301. BUT, what I really want is for only the items with adrscode of 'bill to' to be given an incremented number.
For example, if there are only five rows of 100 with an adrscode = 'bill to' then only five rows will be updated and the value of the custnmbr should be, 278301, 278302, 278303 .....
I could really use some help with this cursor:
Declare @CustomerName as char (60),     @seqno as int,     @BaseSeqno as intset @Baseseqno = 278300
declare c cursor for select custnmbr from NXOFcustomers Where adrscode = 'BILL TO' order by custnmbropen cfetch next from c into @CustomerNamewhile @@fetch_status=0begin set @seqno = @BaseSeqno + 1
update NXOFcustomers set custnmbr = @seqnoWhere custnmbr = @CustomerName                    fetch next from c into @CustomerNameend close cdeallocate c

Cursor

Apr 20, 2001

I have a cursor defined as follows

Declare c_cursor Cursor
Scroll For Select card_id From cardcreator where card_every_cat = @cat_id
Open c_cursor
/* Scroll to the randomly selected row and populate into output parameters */
Fetch absolute @iRandomRecord From c_cursor Into @vi_cardid1
print @vi_cardid1
/*Need to check to fetch status if you have reached end of record set begin from first */
select @@fetch_status
if (@@fetch_status = 0)
Begin
Fetch next from c_cursor into @vi_cardid2
print @vi_cardid2
End
if (@@fetch_status = 0)
Begin
Fetch next from c_cursor into @vi_cardid3
End
print @vi_cardid3

/* Close and deallocate cursor */
Close c_cursor
Deallocate c_cursor

I need to have atleast three records. But if random value starts the cursor at the end, the cursor would not wrap to the beginning.

Is there a way to wrap the cursor to begining if its status is not zero.

Are the cursors declared and opened in stored procedures are always the server cursors?
