How Do I Create A "Cursor" In SQL Server 7.0??
Feb 11, 2000
How do I create a "Cursor" in SQL Server 7.0 that compares an imported table against a exsisting table? Ex. Table1 is my existing table(Destination), Table2 is my imported table(source). I would like to update records in the Destination from the Source but I have to be aware of these three scenarios.
1. If the record exist in the Destination and the Source I will do nothing.
2. If the record exist in the Source and not in the Destination then I will add the record to the destination.
3. If the record exist in the Destination and not in the Source then I will write to the transaction Log.
Note: I am only concerned about updating one column in Destination which matches the only column in the source.
Someone Please help??

I have a SQL statement stored in a SQL varriable (after a lot of conditions)
Code:
declare @sql char(100)
set @sql = 'select ma_kh, ten from _khang'
Now, I want to create a cursor to recalculate some values
I've tried:
Code:
declare cur_T cursor for exec(@sql) open cur_T
but it doesn't work.
Can I have another way to do that???

I have multiple locations that I want to create views for eachindividual location.I am using a cursor to create the views for each location. So, thecursor grabs site #1 then <should> create view_site_#1, then grab site#2 and <should> create view_site_#2.For some reason it doesn't like the view name with the @site in it.Any ideas of how to get this done?Here's the cursor...declare @site varchar(5)declare c_site cursor forselect station from VHAISLCAUDIA.VISN_SITEorder by stationopen c_sitefetch from c_siteinto @sitewhile (@@fetch_status = 0)beginCREATE VIEW Site_All_Data_+ @siteASSELECT *FROM dbo.[600_All_Suggested_Data]WHERE (Site = @site)Print 'View for ' + @site + ' Created'fetch next from c_site into @siteendclose c_sitedeallocate c_sitereturnend

I try to create a Sproc which will use a cursor to retrieve a few rows from a table. But the cursor part has given me problem. Here it is:
StudentInfo
StudentID StudentName DeptID
101 John 10
102 Alex 10
103 Beth 20
ClassInfo
ClassID DeptID
901 10
902 10
225 20
I want to create a Sproc which will retreive the student's classes in DeptID 10
Following is the Sproc and cursor:
use master
go
Create PROCEDURE [dbo].[getEnclishClasses]
@StudentID int
AS
Declare @printInsertStatement nvarchar(100)
ECLARE NewRowID int
Declare classCursor CURSOR FOR
SELECT ClassID, DeptID FROM [myTest].dbo.ClassInfo
WHERE DeptID=(SELECT DeptID FROM [myTest].dbo.StudentInfo
WHERE StudentID=@StudentID)
DECLARE @ClassID INT
DECLARE @DeptID INT
OPEN classCursor
FETCH NEXT FROM classCURSOR INTO
@ClassID, @DeptID
WHILE (@@FETCH_STATUs=0)
BEGIN
PRINT 'SET @newID = Scope_Identity()'
SET @printInsertStatement=
(Select 'INSERT INTO [myTest].dbo.ClassInfo (ClassID, DeptID) Values('
+CONVERT(NVARCHAR (10), @ClassID) + ','
+CONVERT(NVARCHAR (2), @DeptID)+')'
FROM [myTest].dbo.StudentInfo
WHERE DeptID=(SELECT DeptID FROM [myTest].dbo.StudentInfo
WHERE StudentID=@StudentID))
PRINT @printInsertStatement
END
CLOSE classCursor
DEALLOCATE classCursor
EXEC getEnclishClasses 101
Here is what I try to get (text with actual data from the table):
SET @newRowID = Scope_Identity()
INSERT INTO [myTest].dbo.ClassInfo VALUES(901, 10)
SET @newRowID = Scope_Identity()
INSERT INTO [myTest].dbo.ClassInfo VALUES(902, 10)
Here is what I had got (returning multiple lines, more than number of records I have):
Msg 512, Level 16, State 1, Procedure getEnclishClasses, Line 19
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Thanks in advance for your help! Or is it a better way (not using a cursor). Each table has over 5,000 records.

The requirement is create a sql script(1 proc or cursor) which will create multiple procedures dynamically.
Table A
Col1
Col2
A
Alpha
For Example: If table A has 3 rows(distinct) so 3 procedures will be created dynamically.
Result:
1 PROC_A_ALPHA
2 PROC_B_BETA
3 PROC_C_charlie

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 have a cursor in my SQL Server 2000 usp that doesn't seem to be working. It returns 0's for all counts within the cursor. I assigned a value to one of the variables after the cursor and the assigned value came back to my asp.net code. This leads me to believe the cursor variables lose their value once the cursor is done. What am I doing wrong?
--------------------------------------
DECLARE @numFPrintNA int
DECLARE @txtPrintSuit varchar(1)
DECLARE curs_Count CURSOR
FOR
SELECT numFPrintNA,
txtPrintSuit
FROM tblRecords
WHERE txtLocationCode = @txtLocationCode
AND (dtmOffDate >= @dtmFrom
AND dtmOffDate <= @dtmTo)

FETCH curs_Count INTO @numFPrintNA, @txtPrintSuit

I am not fimilar with cursors at all but need some assistance/direction on how to re-create the following.
The result set will need to give me a list of new customers with sign dates of last year and this current year plus their sales for each year. If the customer has a date signed of 2007 I need to see the "year of sales" for both 2007 and 2008, whether or not they actually had sales.
I'm needing to convert an oracle cursor to Sql Server 2005. If at all possible I would like to stay away from the cursor and create this some other way. Any help would be greatly appreciated.
Customer Date Signed Year of Sale Amount

Forgive me if this is a stupid question.
How do you use a Server Side block cursor?
Lets say I have a db of 250,000 items and I want to retrieve the data 100 rows at a time.
How would I do this (using a block cursor, not in general)
thanks,

LOCAL FAST_FORWARD
[code]....
The cursor should only grant access to a particular database. If the user exists within the database it should not execute the script.

I have a table called Table1 where I have five fields like Tableid, Processigndate, Amount, remainingCollectonCount and Frequency. All total I have more than 5Lacs records.
Now I need to fill up another table Called FutuecashFlow taking the records from Table1. There will be also five Columns like FutureCashflowid, Table1id, Processigndate, Amount.
Now the condition is that if the remainingCollectonCount =6 and the frequency is 12 then there will be the 6 entries in the futurecasflow table where the prcessign datae wille be addeed by 1 month.
For example Table1
Tableid, Processigndate Amount remainingCollectonCount Frequency
1 2014-02-15 48 8 12
the future cash flow table the prcessing date column will be shown in the following way
Processigndate
2014-03-15
2014-04-15
2014-05-15
2014-06-15

I need to use WHILE to avoid Cursor under certains conditions.
My SELECT statement is:
SELECT ref, ano, numberofyears ,nreint, naoreint,degress,
tabela, tax, taxamaxima,[evactual],
[evaldepact],[ereintact],nrregbt,[taxAmtAno]
FROM deprec
ORDER BY [ref] ASC
numberofyears= 100 /tax for exemple for a good where lifecycle is 4 years ,ex:
Tax = 25% Then 100/25 = 4 years
I see this WHILE script, but i need to run :
1. for each REF + Until years < 4 in this exemple, because i have goods years depend on Percent.
the WHILE script i see is:
DECLARE @table1 TABLE (Id int not null primary key identity(1,1), col1 int )
INSERT into @table1 (col1) SELECT col1 FROM table2
SET @num_rows=@@ROWCOUNT
SET @cnt=0
WHILE @cnt<@num_rows
[Code] .....
My doubt is how to make the LOOP for each REF until Year < 4 (like my example)

I am trying to calculate cumulative GPA which is currently it is being done via a cursor and i was looking to change it to set based if possible.
The cumulative GPA is basically the average marks of all courses in a term and all previous terms. Where I am having an issue is if the course was taken in a previous term and the mark was lower, then the lower mark in not factored in to the GPA. If a course was taken in a previous term and the mark was higher then the marks for the current term are not factored into the GPA.
In the example below, math is taken in all three terms and the current term's mark is included in the GPA but not the previous terms because current terms mark is higher. Two classes (bio,chem) are taken in third term but not included due to marks being higher in second term.
CREATE TABLE [gpa]([term] int,
[course] varchar(10),
[mark] float);
INSERT INTO [gpa]
VALUES (1,'math',3),
(1,'eng',4),
[Code] .....

I like to backup the stored procedures' code used in my databases. So I created this Script:
/*
IF OBJECT_ID('[Monitor].[dbo].[Procedurecode]') IS NOT NULL DROP TABLE [Monitor].[dbo].[Procedurecode];
*/
DECLARE
@db nvarchar(50),
@strSQL nvarchar (100)
IF CURSOR_STATUS('global','cur1')>=-1 BEGIN DEALLOCATE cur1 END
[code]....
Problem is (and I seem not to be the only one with tis) described here:
"If the executed string contains a USE statement that changes the database context, the change to the database context only lasts until sp_executesql or the EXECUTE statement has finished running." There is nothing magical in SQL server that knows you intend a series of dynamic sql commands to be part of a single job running in a single context. You have to build the entire string for the job you want to execute."

So I only get the SPs of the current database.

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??

Dear all,
I have a procedure in Oracle that contains the following cursor:
CURSOR SCHED_TRIPS IS
SELECT TRAVELDATE, STOP_NUM, TRIPID, STOP_TYPE, PROMISED_TIME, ETA, PERFORM_TIME, DEPART_TIME, ETD, DRIVERWAIT, PASSENGERWAIT, TRIPTIME, GROUP_ID
FROM Dbo.SCHEDTRIPS_VIEW
WHERE UNQ_ID = SESSION_ID AND TRUNC(TRAVELDATE) = TRUNC(TDATE)
AND DISPOSITION <> 'V';
BEGIN
FOR S IN SCH_TRIPS LOOP
UPDATE dbo.SCHEDULES T
SET T.DIRTYBIT = 1
WHERE T.TRIPID = S.TRIPID AND T.STOP_TYPE = S.STOP_TYPE AND (T.STOP_NUM <> S.STOP_NUM OR T.ETA <> S.ETA);
UPDATE dbo.SCHEDULES T
SET T.STOP_NUM = S.STOP_NUM, T.PROMISED_TIME = S.PROMISED_TIME, T.ETA = S.ETA, T.ETD = S.ETD, T.LAST_CHANGED = SYSDATE
WHERE T.TRIPID = S.TRIPID AND T.STOP_TYPE = S.STOP_TYPE;
END LOOP;
COMMIT ;
END;
My problem is with the line shown in Red. What will be the T-SQL equivalent for this line.
Anxiously waiting for help!

I am writing a custom query to determine if a legacy table exists or not. From My CMS Server I already have all the instances I have to query and I store the name of the instance in the @Instance variable. I cannot get those stubborn ticks to work right in my query. Below I am using the IF EXISTS statement to search the metadata for the legacy table.
DECLARE @Found tinyint
DECLARE @Instance varchar(100)
set @Instance = 'The Instance'
IF (EXISTS (SELECT a.*
FROM OPENROWSET('SQLNCLI', 'Server=' + @Instance + ';UID=DBAReader;PWD=DBAReader;','SELECT * FROM [DBA].INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = ''TheTable''') AS a))
SET @Found = 1
ELSE
SET @Found = 0
PRINT @Found

Hi,
We have an application that uses a large number of cursors, and I can run sys.dm_exec_cursors (0) to view them. However, the 'name' column always appears to be NULL no matter when I run the query.
I see, when tracking some blocked processes, that the blocked processes usually have in inputbuffer that looks something like FETCH API_CURSOR00000000000003435 - which I'm trying to map back to the cursor itself. However, I can't seem to do so based on the name - since it isn't in the DMV.
Can anyone shed any light on this one?
Thanks in advance,
Chris Camadella

I have a situation where I need to call a stored procedure once per each row of table (with some of the columns of each row was its parameters). I was wondering how I can do this without having to use cursors.
Here are my simulated procs...
Main Stored Procedure: This will be called once per each row of some table.
-- All this proc does is, prints out the list of parameters that are passed to it.
CREATE PROCEDURE dbo.MyMainStoredProc (
@IDINT,
@NameVARCHAR (200),
@SessionIDINT
)
AS
BEGIN
[Code] ....
Here is a sample call to the out proc...
EXEC dbo.MyOuterStoredProc @SessionID = 123
In my code above for "MyOuterStoredProc", I managed to avoid using cursors and was able to frame a string that contains myltiple EXEC statements. At the end of the proc, I am using sp_executesql to run this string (of multipl sp calls). However, it has a limitation in terms of string length for NVARCHAR. Besides, I am not very sure if this is an efficient way...just managed to hack something to make it work.

I have a temptable with a list of user IDs that I want to drop so I created a script to do a cursor and run through my drop functions. The drops work by themselves and the ver check works with them but when I wrap them in the cursor all i get is an output for each user in the results window in ssms. why it's not setting the variable and instead outputting to results?
DECLARE @ver nvarchar(128);
DECLARE @UserName nvarchar(50);
DECLARE @UserD nvarchar(80);
DECLARE @LoginD nvarchar(80);
-- Initialize the variable.
SET @ver = CAST(serverproperty('ProductVersion') AS nvarchar)
[code]...

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.
CREATE PROCEDURE procedure1
AS
DECLARE cursor_1 CURSOR FOR
SELECT
'This is a executable query'
FROM table_1
DECLARE @table_2
[code]....
