I have been using dynamic sql in an inner cursor and I get an error about the fetched variable of the outer cursor. How can I fix it?
DECLARE A1 CURSOR GLOBAL FOR
SELECT Iid, Server, Dbname
FROM@OuterTable;
[code]...
The below cursor is giving an error
DECLARE @Table_Name NVARCHAR(MAX) ,
@Field_Name NVARCHAR(MAX) ,
@Document_Type NVARCHAR(MAX)
DECLARE @SOPCursor AS CURSOR;
SET
@SOPCursor = CURSOR FOR
[Code] ....
The @Table_Name variable is declared, If I replace the delete statement (DELETE FROM @Table_Name ) with (PRINT @table_name) it works and print the table names.
Why does the delete statement give an error ?
Each patient has multiple diagnoses. Is it possible to concatinate all of them in one without using a cursor?

How do loop a table server(serverlist,flag) table with these 2 columns.And ping each of the servers in the table and update the flag column to '1' if ping has been successfull or flag to '0' if ping has been unsuccessfull.
I am using a cursor (i know - but this is actually something that is a procedural loop).
So effectively i have a table of names of stored procedures. I now have a store proc that loops around these procs and runs each one in order.
Now i am thinking i would like to be able to set the table it loops around in a variable at the start - is it possible to do this? So effectively use a tablename in a variable to use in the sql to define a cursor?
i wanna create a procedure for P& L cost sheet , i had done that procedure now include a cursor instead of replacing sql queries .

how to include cursor on if part and else part
Need getting the below Cursor query convert to a Recursive CTE or with a while loop as I do not want to use a cursor.
Declare @Companyname Nvarchar (400)

I don't understand using a dynamic cursor.
Summary
* The fetch next statement returns multiple rows when using a dynamic cursor on the sys.dm_db_partition_stats.
* As far as I know a fetch-next-statement always returns a single row?
* Using a static cursor works as aspected.
* Works on production OLTP as well as on a local SQL server instance.
Now the Skript to reproduce the whole thing.
create database objects
-- create the partition function
create partition function fnTestPartition01( smallint )
as range right for values ( 1, 2, 3, 4, 5, 6, 7, 8 , 9, 10 ) ;
[Code]....
Why does the fetch statement return more than 1 row? It returns the whole result of the select-statement. When using a STATIC cursors instead I get the first row of the cursor as I would expect. Selecting a "normal" user table using a dynamic cursor I get the first row only, again as expected.
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
[Code]....
I am trying to think of a way to read a control table, build the SQL statement for each line, and then execute them all, without using a cursor.
To make it simple... control table would look like this:
CREATE TABLE [dbo].[Control_Table](
[Server_Name] [varchar](50) NOT NULL,
[Database_Name] [varchar](255) NOT NULL,
CONSTRAINT [PK_Control_Table] PRIMARY KEY CLUSTERED
[Code] ....
So if we then load:
insert into zt_Planning_Models_Plant_Include_Control_Table
values ('r2d2','planing1'), ('r2d2','planing7'), ('deathstar','planing3')
Then you would build a SQL script that would end up looking like the following (note all the columns are the same):
insert into master_models
Select * from r2d2.planning1.dbo.models
insert into master_models
select * from r2d2.planning7.dbo.models
insert into master_models
Select * from deathstar.planning3.dbo.models
I have a cte:
With cte as
(
Select distinct Incident_ID,
ACTUAL_SEVERITY ,
Policy
From
table)
There are 3 ACTUAL_SEVERITY value: 1-High, 2-Medium and 3-Low
I need the final result be like:
Policy High Medium/Low
How do I write the script with out using temp table or cursor?
I have a stored proc I want to convert it to either a Normal Query using A while loop or a set based operation/recursive cte as I want to run it for multiple CompanyNames. I get the error message as An INSERT EXEC statement cannot be nested when I execute if for Multiple Companies using another Cursor
If I convert it to a Function I get the below error message
Invalid use of a side-effecting operator 'EXECUTE STRING' within a function
converting this query to a normal query or let me know if there is any change which need to done to work with multiple companynames.
CREATE PROC [dbo].[USPT] @CompanyName varchar(50),@tablename varchar(50)
AS
BEGIN
-- EXEC [USPT] 'xyz corp','Sales Header'
DECLARE @str1 VARCHAR (MAX)
set @str1 = '
DECLARE @No VARCHAR (MAX)
[code]....
I currently have a process that has a cursor. It takes data and executes a stored procedure with parameters.
declare @tmpmsg varchar(max)
declare @tmpmsgprefix varchar(max)
declare @cms varchar(20)
create table #tmpIntegrity(matternum varchar(10),ClientName varchar(20))
insert into #tmpIntegrity(matternum,ClientName)

The following Client3 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3
The following Client4 accounts have A1 value and a blank A2 field. Accounts:
Next, how do I call the stored procedure without doing it RBAR? Is that possible?

Hi Friends ,
When i am trying to store a table under a database , it gives me an error that
'Invalid Cursor Status ' and it does not allow me to store that table .
The server is SQL Server 7.0 with Service pack 3.
Can somebody help me in getting this resolved please ?
Thanks

We are getting an error while running a stored procedure,
This is not the exact error but it is roughly:
'cannot complete cursor operation because table schema changed after cursor declaration'
Any ideas as to what causes this?
Thanks,

Hello group
I need some help and gaining knowledge per the SQL Standards.
I have a Stor Procedue which Cursor through say MASTER. This table have information/ Counm that guides me to multiple say two different table.
i.e, Col1 in MASTER table have the information on what table I need to work on COL2 in MASTER Table give me what Field I have to work on and accordingly move the data
Example :
MASTER
ID COL1 COL2 COL3
1 Address Street Nichols Rd.
1 Address Zip 90001
2 Address Street Michigan Ave
2 Address Zip 90002
3 Person FName James
3 Person LName Bond
4 Person FName Bill
4 Person LName Gates
Address
ID Street Zip
1 Nichols Rd. 90001
2 Michigan Ave 90002
Person
ID FName LName
3 James Bond
4 Bill Gates
For doing this I created a Store Procedure which Cursor thru MASTER table which for each row goes to Entity on which it has to work (MASTER Table : Col1 Value) and in that entity Its goes to the Field(MASTER Table: Col2 Value) and places the value of the Col3 in it.
It is working fine and superb. Now, I try to introduce Error Handling such that incase in order to see if there is any error while doing this INSERT and UPDATE.
SAMPLE QUERY: (Structure is Same but modified for readability)
UPDATE @ENTITY SET @FIELD = @VALUE WHERE ID = @KEYID
IF @@ERROR <> 0
BEGIN
INSERT INTO dbo.ErrorLog VALUES( @KEYID + ' , '+ @ENTITY + ' , ' + @FIELD +' , ' + @VALUE )
END
This query is working fine . If there is any error and for some reason if its not able to insert/update the data Its populates the ErrorLog Table and instead of failing the store proc goes for the next row and do teh necessary action
Finally SProc does what it has too
1) Get the data in teh respective tabel and colunm
2) if it cannot insert/ update go for the next row and populate the error log table with what it was n't able to update/ insert
SO Whats the problem? Good question , here is the issue or topic of discussion
1) What is the standard way of Error Handling. Did I atleast follow teh minimum Error Handling criteria.
2) I can see from teh table that, as required, its skipping the row into Error Log table whenevr its not able to do the required functions and going for next row
3) I introduce a Error and when I execute the Sproc it gives me Mesaage:
Msg 8152, Level 16, State 14, Line 1
String or binary data would be truncated.
The statement has been terminated.
Also I see that "Query Completed with Errors" well I said whenever teh SPROC see error do some thing else, then why would it count it as error and give me this message? Why is the SPROC failing.
What Should I do such that it counts or give when ever there is a genuine error. I mean it should not fail at all because I am saying there whenever there is an incapability of Insert/ Delete just simply skip the row and Insert that row in Error Log Table.
Am I missing something in this Proc?
If it will do that then is tehre any way or query or anything I have to do that handles the issue that
Whennver its not able to do whatever I am asking it to do (Ex: If I am asking it to insert INTEGER in Character Field) then an error is raised then just skipp that row insert that row in erro log and go for next row and dont fail the SPROC.
THANKS FOR THE PATIENCE FOR READING AND REPLYING.
I've implemented a UDF in SQL Server 2005 written in C#. The function with its assembly has been registered ok with SQL Server and works fine. It accepts three short strings (nvarchar of lengths 5, 35, and 35) and returns a SQL formatted string (SqlString).
When I run the function to test it it works just fine, and the same is true if I run the function inside a cursor to update a field in a table. But when I do a simple update it crashes. I've so far received two different errors: first one error saying a string could not be converted into an integer (but the error does not occur when I enter the same input values manually via a test Windows form, or through the new Query Analyzer as a single query - or using it inside a cursor). Then one error saying a string was too short (I couldn't use substring(X, Y) because the string, I was told, was too short - it wasn't).
The problem thus cannot be with the function since it works just fine if I do like this:
UPDATE myTable SET CodeField = dbo.fnMyFunction(Field1, Field2, Field3) WHERE PersonId = 10000001
And it works fine while doing the same thing inside a cursor (for instance working with the first 10, 100 or 1000 records).
But when I do this it crashes:
UPDATE myTable SET CodeField = dbo.fnMyFunction(Field1, Field2, Field3)
For your information the table has about 1.5M records (for testing, it contain more data when on the production server) and my aim is to update the CodeField column as quickly as possible. The CodeField is a 12-character string that is based on a rather complex algorithm including the Field1, Field2 and Field3 strings. I'm using C# because it manages strings much better than SQL Server - and it is so much easier coding this stuff.
Anyhow, I've had this kind of problem before with SQL Servers 2000 and 7 (maybe even 6.5) and it seems the problem occurs when I let SQL Server go about its business at its own pace. But when I do something to control that it really takes one record at a time (through using a cursor or executing the query with a WHERE clause like the one above) it works splendidly.
The problem here is that a cursor is way too slow, and there really shouldn't be a problem with a simple UPDATE command, should it? After all, everything works just fine except when I let SQL Server do what it does best (i.e. update the field at its own speed, whatever that is).
Any ideas? This is very frustrating since it is impossible to try and find the error - it isn't there when testing! And it is frustrating since I remember having had the same kind of problem (but every time with different errors arising) before without finding a solution (except for slowing everything down - not an option here).
Is there a certain tweak I can do to make things work out, or should I code things differently?
Thanks!
One of the people I have to support gets an error message when they are trying to use a SQL based application that was developed in house:
an error occured..microsoft odbc sql driver cursor type change. location frn main, load user () source is odbc
Unfortunately, the developer is not available to troubleshoot the issue and I do not understand it. I thought ODBC settings were static, so how could they cause a cursor to change?
I get the following errors while running a SQL procedure.

Hello:
We have an old 16-bit app that runs fine in SQL 7.0 but on our test SQL 2000 box some reports generate the following error "System Message 10202 - The application fetch buffer size is less than the cursor select statement requires".

View 2 Replies View Related 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

Using SQL native client from VFP 9.0 to SQL Server 2005 64 bit SP1 (happened before SP1 too)..
We have a stored procedure that returns 6 result sets. This SP uses 2 cursors. It is rather lengthy - I'll post the code if needed.
This SP works fine when called from VFP 99 percent of the time. Normally takes 2 to 3 secunds to execute.
Once in a while we will get a return from SQL ..
"OLE IDispatch exception code 0 from Microsoft SQL Native Client: A server cursor cannot be opened on the given statement or statements. Use a default result set or client cursor..."
The OLE error code is 1429. An OLE Exception code 3604 is also returned.
When this happens the SP will return the same error when executed for the same parameters over and over when called from VFP. When called directly from SQL management console it will normally work for the same parameters, although once in a while it will just hang (and not timeout apparently). In that case it will also hang from SQLCMD command line utility as well.
Wait a few hours and the SP will run fine for the same parameters in VFP. This happens even in the middle of the night when there is no possibility that data is being changed.
Here's the really fun part...
Open the SP source for modification (ALTER PROCEDURE) in management console and execute it (no changes at all, just let it recompile). Immediately it will work fine when called with the same parameters called from VFP or anywhere else (even if it was one of the rare instances where it hung in management console). This works EVERY TIME.
Sooo... I edited and executed the SP with the WITH RECOMPILE option assuming that that should do the trick (same as alter procedure/executing from management console right?). NOPE. Same problems. In order to work around the problem when the error occurs, I HAVE TO alter procedure and execute the code from management console.
Help??

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

Cursor is not open.
here is the stored procedure:

example useage:
EXEC sp_MSforeachsp @command1="PRINT '?' GRANT EXECUTE ON ? TO [superuser]"

These errors occur at the subscriber. First, "The merge process could
not query the last sent and received generations" is generated, then
immediately afterwards, "invalid cursor state" is generated. We are
trying to pull a new subscription snapshot from the republisher. The
subscriber has been added and removed from the replusher's pull
subscriptions a number of times for testing. Now, we cannot get the
subscriber to re-sync with the republisher.
Any ideas?
I am having SP where I am pulling data from linked server. Previously its working fine but suddenly started to give below error.
Msg 15281, Level 16, State 1, Procedure Procedure_Name Line 184

I have some T-SQL that generates HTML code by using the FOR XML PATH functionality. Once the HTML is built, I am using the following T-SQL to convert it to XML so I am not limited by the output
SELECT @vHTML AS [processing-instruction(x)]
FOR XML PATH('')
where @vHTML is varchar(MAX)
Now, when I run my code in VB.NET and use the ExecuteXMLReader() command, I get nothing back into the XML Reader. I noticed that I needed the XMLDATA directive also, but when I add it, I get the following error
Msg 6860, Level 16, State 1, Line 247
FOR XML directive XMLDATA is not allowed with ROOT directive or row tag name specified.
