if I use SqlStatement to insert records of servertable into NewServerTable
like this :
Insert Into NewServerTable
Select From Server Table.

and If I use Cursor for the same thing like this

DECLARE db_cursor CURSOR FOR
SELECT SERVERID,SERVERNAME
FROM SERVERTABLE
DECLARE @SERVERID INT
DECLARE @SERVERNAME VARCHAR(20)
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @SERVERID,@SERVERNAME

WHILE @@FETCH_STATUS = 0
BEGIN
FETCH NEXT FROM db_cursor INTO @SERVERID,@SERVERNAME
INSERT INTO NEWSERVERTABLE(SERVERID,SERVERNAME) VALUES (@SERVERID,@SERVERNAME)
END

CLOSE db_cursor
DEALLOCATE db_cursor

I known to this that sqlqueries are much better in performance as compare to Cursor But How? Please give me explanation.

My question is very simple, i want to know if i can perform the operation of right outer join by using left outer join just by swapping the table.
Then what is the use of right outer join.
If there any difference between them please let me know.

Thanks in advance…….

With the release of SQL Server 2008, Microsoft has introduced new datatype Cursor. Previously, we were using Cursor as Database Object.

So, in my opinion, Cursor is Data Type and Database Object also.

The only difference being the way it is used.

Hope it helps.

Cursor is not a data type, it is an object but it has to be declared as cursor. Rows fetched out of a query is stored into this cursor in the RAM. If the query fetches large amount of data, then it occupies large amount of RAM capacity. Obviously other objects cannot be loaded into the memory as the cursor occupies more memory. Naturaly the performance of the SQL server is also pulled down. Thats why it is advised not to use cursors if you can implement some other logic to manipulate row by row.

There is some thing called as books online. Please refer to that and you will get all information regarding cursors. Other wise make use of Google Search Engine.

Let us know, if you have any (serious) questions.

now i have a question , i m writing a stored procedure using cursor.

set @test_temp_query_one = ‘ SET

@test_temp_count_one = CURSOR FORWARD_ONLY

STATIC FOR SELECT MAX(FLID) FROM ( SELECT TOP ‘ +

cast(@VAR_DIVIDE2 as varchar(50)) + ‘ FLID FROM ‘+

cast(@var_table as varchar(50)) +’ WHERE (FLFILENO

!=’ + cast(@VAR_SLIP_NO as varchar(50)) +’) ORDER BY

FLID ) FLID ; OPEN @test_temp_count_one ‘

EXEC sp_executesql @test_temp_query_one , N’

@test_temp_count_one CURSOR OUTPUT’,

@test_temp_count_one OUTPUT
FETCH NEXT FROM @test_temp_count_one INTO @VAR_FILE_RANGE2

this is a part of the proceduer because it’s so long…

when i am executing this procedure the i got an error

“Operand type clash: nvarchar is incompatible with cursor”

this pro executing with c#.net pro .

now my question is……

tell me the list of datatype , those incompatible with cursor in sql server 7.0

tahnks in advance

So in my mind, it’s a database object and not a datatype (contains more information, and from all different datatypes)

select leavetype,(abs(substring(loofhours,4,5))*100/60) as totalnoofhours from tablename order by totalnoofhours asc;

i have a table named leave having field like leavetype, from, to,
noofhours
how can i retrive the row by row wise inorder to calculate the noofhours
ie
these are the data of noofhours field
10.50 (it equals 10 hours n 30 min)
20.50
12.25

i want to get the each row n split the 10.50 value to two
ie. 10 n 50 n make a calculation like 50*100/60
ie i want to make the 50 into clock time
after each calculations i want to add all the data
n return the result
how can i do this …………
can u pls help me
