UPDATE: For working example using AdventureWorks visit : SQL SERVER – Simple Example of Cursor – Sample Cursor Part 2
This is the simplest example of the SQL Server Cursor. I have used this all the time for any use of Cursor in my T-SQL.
DECLARE @AccountID INT
DECLARE @getAccountID CURSOR
SET @getAccountID =Â CURSORÂ FOR
SELECT Account_ID
FROM Accounts
OPEN @getAccountID
FETCH NEXT
FROM @getAccountID INTO @AccountID
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT @AccountID
FETCH NEXT
FROM @getAccountID INTO @AccountID
END
CLOSE @getAccountID
DEALLOCATE @getAccountID

diff bet result set,data set and data table in sql
Hi,
I have written a cursor in MS SQL server and was able to execute it also. But i have an issue where it’s not displaying the results in the order what i have written it’s displaying randomly. First I am selecting the records from Info table and then from sinfo table.
Example:
DECLARE emails CURSOR FOR select distinct LTRIM(RTRIM(useremail)) from Info
UNION
select DISTINCT LTRIM(RTRIM(useremail)) from SInfo
SET NOCOUNT ON
DECLARE @email varchar(100)
OPEN emails
FETCH NEXT from emails
WHILE @@FETCH_STATUS = 0
BEGIN
FETCH NEXT from emails into @email
select username, password, email from info where useremail = @email
union
select username, password, email from Sinfo where useremail = @email
END
CLOSE emails
DEALLOCATE emails
Any suggestions would be much appreciated.
Thanks

Based on what I have understood from your query I have done something…
Create table t_Employee
( EmployeeID Int,
EmployeeName nVarChar(20)
)
Create table t_Deduction
( DeductionID Int,
Description nVarChar(20)
)
Create table t_EmployeeDeductions
( EmployeeID Int,
DeductionID Int
)
INSERT TABLE t_Employee
Select 1,’ABC’
UNION ALL
Select 2,’DEF’
UNION ALL
Select 3,’GHI’
UNION ALL
Select 4,’CAT’
UNION ALL
Select 5,’ABC’
INSERT TABLE t_Deduction
Select 1,’PF’
UNION ALL
Select 2,’Phone Bill’
UNION ALL
Select 3,’Insurance’
INSERT TABLE t_EmployeeDeduction
Select 1,1
UNION ALL
Select 1,2
UNION ALL
Select 1,1
UNION ALL
Select 1,2
Select top 2 ED.*
from t_Employee AS Emp
INNER JOIN
t_EmployeeDeductions ED
ON Emp.EmployeeID = ED.EmployeeID
Now if you have any question please feel free to revert…

when i am creating an SSIS, where I need to do a merge join between Excel source data and OLEDB source data(data from SQL table),ofcourse after sorting, it is giving me the following errors not on merge join but on retrieving data from the OLEDB source itself as the data is huge-in crores, so tell me the solution if u have one, wud b thankful, the reason why i am doing merge join is i have data in the excel file out of which some records are there in SQL database and i want to know what data is there and what is not , the data is in the related tables . Also i want the output containing the columns of excel as well as the columns (fields) of the tables in a single excel sheet so that the other persons or should i say the users of the data can get to know what data is useful and they want to compare.
i want to match on 5 fields, say firstname,lastname,city,state and the first 5 characters of the street address.how can i use LTRIM,RTRIM,LEFT and UPPER string functions on the data i have imported from excel?
Sorry, so many questions, but i really need help.
Thanks

Hi Malaya
u are right but i dont need that solution as my problem is i am getting the data from three related tables.say, i am grouping on a field from Table A and against every group i am calculating sum of values from a field which is in table B and also i am sorting on this sum field and now i get say 20 -30 records for each group, but i want to have top 3-3 from each group.
I dont want to store the intermediate dat in any of temp tables.
I just want a single query.
If u can help, i really appreciate.
Thanks
Taruna

Thank you. it’s userfull
good example…
pinal plz share SSIS architecture
Some indentation would be nice. Leaving your page and googling for something clearer.
