Using Cursor For Manipulation
Oct 17, 2014
ALTER procedure [dbo].[sp_debit_credit]
as begin
SET NOCOUNT ON
DECLARE @DEBIT_ID INT
DECLARE @CREDIT_ID INT
DECLARE @servicedamount decimal(18,2)
declare @bal_Serviced_Amt decimal(18,2)
[Code] ....
table is like this
------------------------
DEBIT.ID, DEBIT.ACCOUNT_NO,DEBIT.SERVICED_AMT,CREDIT.ID,CREDIT.TRAN_AMT,CREDIT.SERVICED_FLAG,credit.Serviced_Amt
1456050866223983.0006418110.000300000.00
1456050866223983.0006419110.000500000.00
1456050866223983.0006447110.0002800000.00
1456050866223983.0006510110.0003100303.00
[Code] ....
I need result, I have to subtract
(DEBIT.SERVICED_amt - CREDIT.TRAN_AMT) and set CREDIT.SERVICED_FLAG =1 ,
if DEBIT.SERVICED_amt = CREDIT.TRAN_AMT then set debit.SERVICED_FLAG =1
Using with cursor. It will check row by row , i have written stored procedure , but flag is not updated .

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

Have an XML file that i load in to a Dataset. works fine, it builds its own scheme perfectly.
I loop through that data to load a check list which also works wonderfully.
two questions based on that.
1) can i add a column after the fact? I want to basically update the the info in the dataset to store if the record was checked in the check list. if not, i can manipulate one of the already defined columns, but i would rather not.
2) what is the best way to update data with in the dataset? Never really done anything but pull data from one. how do i locate the correct row to update ("select name from tbl where name = " + checklist.items[index].tostring(); update row)
sorry for the fairly basic question. i appreciate the help.

I was given a script that was supposed to take a name field that was separated by commas and normalize it into last, first and middle name. My data looks like below in one fieldname called longname
crab,mike,Allen
Lota Weilly,Eric,M
My script to do this looks like
update ailoca
set last_name = substring (longname, 1, patindex( '%,%' , longname) -1 ),
first_name = substring (longname, patindex( '%,%' , longname) + 1, patindex( '% %', longname)-patindex( '%,%' , longname)),
middle_name = substring (longname, patindex( '% %', longname) + 1, len(longname)-patindex( '%,%' , longname))
My problem is that some people actually have 2 last names, not hyphenated, but 2. Whenever I have 2 names I get the following error
Server: Msg 536, Level 16, State 3, Line 1
Invalid length parameter passed to the substring function.
The statement has been terminated.
It seems to be related to the first name, I can comment out that update and it works
Thanks

Hi, is there a way i can replace multiple white spaces & tabs into one , on a TEXT column ?
I am using replace function and trying to store the result into a varchar variable and the TEXT being truncated after 255 charecters.
for example, I tried this :
declare @str varchar(4000)
select @str = replace(cast(textcolumn as varchar(4000)), ' ', NULL)
I understand t-SQL dml statement(s)
will automatically truncate after 255 chars in a long string. But, seeking for other options here pls.

I have two tables TableA and TableB as shown in the example below. I will have to Update TableA based on the data in TableB.
If a member in TableB has an EmployerId different from the one in TableA where the EffectiveDate in TableB between the EffectiveDate and ExpirationDate in TableA, then it should void the row in TableA and create rows as shown in the example below (Please refer to the 1st record and the last three records).
I would like to get some suggestions on how to do this efficiently. I am not looking for queries, but I need some ideas...
Thanks in advance.
TableA
MemberId EmployerId EffectiveDate ExpirationDate VoidIn
12345 111 1/1/2006 10/31/2006 0

12345 333 6/1/2007 12/31/9999 0
TableB
MemberId EmployerId EffectiveDate
12345 444 4/1/2006
TargetTable (TableA Updated)
MemberId EmployerId EffectiveDate ExpirationDate VoidIn
12345 111 1/1/2006 10/31/2006 1
12345 222 11/1/2006 5/31/2007 0
12345 333 6/1/2007 12/31/9999 0
12345 111 1/1/2006 3/31/2006 0

Hello,
I have to perform some data manipulation based on ID1, ID2 with respect to Effective dates (below represented as effdt)
Source Code:
create table #source (id1 int, id2 int, effdt datetime)
insert into #source values (111, 123, '1/1/2007')
insert into #source values (111, 123, '3/1/2007')
insert into #source values (111, 123, '4/1/2007')
insert into #source values (111, 124, '5/1/2007')
insert into #source values (111, 125, '6/1/2007')
insert into #source values (111, 123, '7/1/2007')
Source Code Data:
ID1 ID2 Effdt
111 123 1/1/2007
111 123 3/1/2007
111 123 4/1/2007
111 124 5/1/2007
111 125 6/1/2007
111 123 7/1/2007
Target Data should look like:
ID1 ID2 Effdt Expdt
111 123 1/1/2007 4/30/2007
111 124 5/1/2007 5/31/2007
111 125 6/1/2007 6/30/2007
111 123 7/1/2007 7/31/2007
The logic is like the min(effdt) as effdt, min(effdt) - 1 as expdt of the next id2 from the source. Nut the problem comes when the same ID2 comes later after a different id2, so just a group by on id1, id2 does not suffice.
If it is the last record then the expdt is that month's end date.
Can someone throw me some light on what kind of logic I should be using to accomplish this.
Thanks in advance.

I have a web page called homepage.aspx created in Visual Studio 2005 using VB. It contains some hyperlinks on the left side. I have a database created in SQL Server 2005. I need to add, delete, edit, update data in the database directly from this same page. How can I achieve this?. i.e is it possible to, say, have a form on a section of this same web page that would allow me to directly manipulate/modify and update the database? (If you may give code, you may use abstract names for the database, tables and column and/or field names-I will understand). Many thanks in advance.

Given any date, how can I change that date to be one of the next 3 year cycle dates.
These are the fixed cycle dates (always on Sep 1 on those set years)
9/1/1997
9/1/2000
9/1/2003
etc.
For example,
if the supplied date was January 4, 1998, it would convert to September 1, 2000
October 31, 2000 -> September 1, 2000
Decemb 12, 2005 -> September 1, 2006
January 1, 1995 -> September 1, 1997
