Simple Cursor Script Not Working
May 21, 2008
I was wondering why this simple cursor script was not working. And by not working i mean that visual studio can't detect that there are parameters that need to be typed in. Was wondering if there was some incorrect syntax somewhere around declaring the parameter vars. Any help at all would be much appreciated.

I need to return one record with concatenated string fields from a table that may contain several records. I think a cursor will be able to do what I want, but I'm not very experienced at writing them.
My data
HDR DMCD
107 TEX
107 AIR
107 LG
108 TEX
108 CAR
109 SM
I want the result of my query to find adn return each header and return the 1 or more DMCD field values concatenated. i.e.
107 TEX AIR LG
108 TEX CAR
109 SM
This is my attempt at the cursor so far
SET NOCOUNT ON
DECLARE @AACODE varchar(50),@hdr varchar(20),@dmcd varchar(20)
DECLARE AAROW_cursor CURSOR FOR
SELECT aaglhdrid,aatrxdimid
FROM aag30003
OPEN AAROW_cursor
FETCH NEXT FROM AAROW_cursor
INTo @hdr, @dmcd
WHILE @@FETCH_STATUS = 0
BEGIN
set @aacode=@aacode+@dmcd
select @hdr,@dim,@aacode
FETCH NEXT FROM aarow_cursor
INTO @hdr, @dmcd
END
CLOSE AAROW_cursor
DEALLOCATE aarow_cursor

I'm trying to build a simple cursor to understand how they work. From the temp table, I would like to print out the values of the table, when I run my cursor it just keeps running the output of the first row infinitely. I just want it to print out the 7 rows in the table ...
IF OBJECT_ID('TempDB..#tTable','U') IS NOT NULL
DROP TABLE #tTable
CREATE TABLE #tTable

I'm tryng to set a cell of my table to this :
=IIf(Sum(Fields!Field2.Value)<>0, Sum(Fields!Field1.Value) / Sum(Fields!Field2.Value), 0 )
I cant figure out why when Sum(Fields!Field2.Value) = 0 i always get #Error on the specified cell.
Is the condition evaluated in advance?
If i set a Public Function in the Report Code, that does the work for me, the value 0 (for the case examined) is returned correctly.
Thanks in advance for any suggestion.

I wrote a stored procedure (see below), which within a database create a new column (Ordering)and order rows that have the same OID, DECISION_DATE and give a to column ORDERING value 1 to the highest VOTES_REQUIRED VALUE, VALUE 2 to the second Hignest value and so On.
In Other words I am creating a sort on Index (ORDERING Column) on subsets of the database which have same OID and DECISION_DATE based on the value of VOTES_REQUIRED.
The stored procedure is working and I get the right results, but IT TAKES 3 HOURS 30 MINUTES to go through 38,000 rows. I have to run this stored procedure for a database with 200,000 rows (it may take tens of hours...).
Is there any idea to improve the following code to make it run efficiently.
Thank you in Advance.

If I set it to 0 which is disabled, the user can still login.
Therefore I want users that have activate as 1 to be able to login and users with activate as 0 not to login
what are mine doing wrong ?
Please help

dear friends,
i started using Asp.net for developing webparts, web parts automatically connect to a database to be created and saved in the database.
i had already Sql Server 2005 Express Edition installed so my webpart page ran and automatically created the database "AspNetDb" in the "App_Data" folder.
but when i uninstalled Sql Server 2005 Express Edition and then installed the Sql Server 2005 Enterprise Edition, it gave me the following Error 26 as below :
--------------------------------------------------------- Beginning of Error Message --------------------------------------------------
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. SQLExpress database file auto-creation error:
The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:
If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist.
If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database.
Sql Server Express must be installed on the machine.
The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.
--------------------------------------------------------- End of Error Message --------------------------------------------------
then when i checked the Machine.config file, i found this....
<connectionStrings> <add name="LocalSqlServer" connectionString="data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" /> </connectionStrings>
then i thought it's becoz, of the datasource thing that the Machine.Config file supports by default the default free edition of Sql Server 2005 which is the Sql Server 2005 Express Edition.
but friend in my company we use Sql Server 2005 Enterprise Edition, so can anybody pls guide me and get me out of this soup on helping me to use Sql Server 2005 Enterprise Edition by modifying either 1) Machine.Config File and/or 2) Web.Config file and/or 3) any other way, but please help i want to do this, please......
regards and thanks

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.

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

hi
I had a view in which I did something like this
isnull(fld,val) as 'alias'
when I assign a value to this in the client (vb 6.0) it works ok in sql2000 but fails in 2005.
When I change the query to fld as 'alias' then it works ok in sql 2005 .
why ?? I still have sql 2000 (8.0) compatability.
Also some queries which are pretty badly written run on sql 2000 but dont run at all in sql 2005 ???
any clues or answers ?? it is some configuration issue ?
Thanks in advance.

I am writing a pgm that attaches to a SQL Server database. I have an Add stored procedure and an Update stored procedure. The two are almost identical, except for a couple parameters. However, the Add function works and the Update does not. Can anyone see why? I can't seem to find what the problem is...
This was my test:
Dim cmd As New SqlCommand("pContact_Update", cn)
'Dim cmd As New SqlCommand("pContact_Add", cn)
Try
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@UserId", SqlDbType.VarChar).Value = UserId
cmd.Parameters.Add("@FirstName", SqlDbType.VarChar).Value = TextBox1.Text
[...etc more parameters...]
cmd.Parameters.Add("@Id", SqlDbType.VarChar).Value = ContactId
cn.Open()
cmd.ExecuteNonQuery()
Label1.Text = "done"
cn.Close()
Catch ex As Exception
Label1.Text = ex.Message
End Try
When I use the Add procedure, a record is added correctly and I receive the "done" message. When I use the Update procedure, the record is not updated, but I still receive the "done" message.
I have looked at the stored procedures and the syntax is correct according to SQL Server.
Please I would appreciate any advice...

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

I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday)
1 1 a b c d e m
1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
Any help is appreciated.

Hi,
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
I have:
Master table Hotel
table AddressCrossRef (with: RefID = Hotel.ID, RefType = 'Hotel', AddrID)
joins
table Address (key = AddrID)
table MediaCrossRef (with RefID = Hotel.ID, RefType= 'Hotel', MediaID)
joins
table Media (with MediaID,mediaType = 'thumbnail')
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have
left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using
where (media.mediaTyple like 'thumbnail' or media.mediaType is null)
but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
any clue?
thanks

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.

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

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?

I am sure I am not the first one ask this.
I have got two tables, what I would like to do now is to update the second table using the values in the first table where
T1.id = T2.id, normally I have to use cursor to loop through table two to achieve this. But is it possible to do this without using cursor?
Thanks,
Alan
