What Do You Think About The Checksum Function ?
May 29, 2007Hi,I'd like advices about an idea I add to resolve a problem. thanks toyou in advance for yours answers.I have a database with tables that I load with flat file. The size ofeach table is 600 Mb. The flat file are the image of an applicationand there is no updated date or created date on any table. So mytables are just a copy of the data from the flat file.Now I'd like to create an History Table. So I have to determine whichlines changed and which one did'nt.As I don't have any date on my row the only answer I had unil know wasto check each column on each row to see if any data changed. If thedata changed I add a new line in my history date.My idea is to add a checksum column in both table on all columns. Toknow if any data change I just have to check my PK + my checksumcolumn.Do you think that is a good idea ? Is checksum a quick function ornot ?.Thanks.--K

Aug 14, 2014From what I've seen, the CheckSum_Agg function appears to returns 0 for even number of repeated values. If so, then what is the practical use of this function for implementing an aggregate checksum across a set of values?
For example, the following work as expected; it returns a non-zero checksum across (1) value or across (2) unequal values.
declare @t table ( ID int );
insert into @t ( ID ) values (-7077);
select checksum_agg( ID ) from @t;
-----------
-7077
declare @t table ( ID int );
insert into @t ( ID ) values (-7077), (-8112);
select checksum_agg( ID ) from @t;
-----------
1035
However, the function appears to returns 0 for an even number of repeated values.
declare @t table ( ID int );
insert into @t ( ID ) values (-7077), (-7077);
select checksum_agg( ID ) from @t;
-----------
0
It's not specific to -7077, for example:
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
0
What's curious is that (3) repeated equal values will return a checksum > 0.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
-997777
But a set of (4) repeated equal values will return 0 again.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777), (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
0
Finally, a set of (2) uneuqal values repeated twice will return 0 again.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (8112), (-997777), (8112);
select checksum_agg( ID ) from @t;
-----------

Checksum Task Vs T-sql Checksum
Feb 29, 2008do you have to store the checksum from the task in order to verify change? Here is what I did and it seems it's not going to work
Lookup transformation that
selects matching fields and returns a t-sql with the binary_checksum(fields)
Checksum transformation returns the checksum of same inbound fields
conditional split passes on changed records to the update
getting all the records everytime and should not be happening.
is there a way to make this work or do I have to store the checksum

Checksum Computation Help
Feb 6, 2004Please execute the script below to understand the problem -
---
create table test(id int, col1 int,col2 varchar(5),col3 datetime)
create table test2(id int, col1 int,col2 varchar(5),col3 datetime)
--id & col1 make up the PK.
insert test values(4,4,'d','02/06/2004')
insert test values(4,4,'e','02/06/2004')
insert test2 values(4,4,'d','02/06/2004')
insert test2 values(4,4,'e','02/06/2004')
select *
from test
select *
from test2
--The rows are identical.
--Script A
select t.*
from test t
join test2 t2 on t2.id=t.id
where CHECKSUM(t.col2,t.col3)<>CHECKSUM(t2.col2,t2.col3)
--The purpose of the above script is to check for any updates in the two tables. It returns two rows. But as you can see both these rows were present in the table before. So I modify the script to -
--SCRIPT B
select t.*
from test t
join test2 t2 on t2.col2=t.col2
where CHECKSUM(t.col3)<>CHECKSUM(t2.col3)
-- In this case no row is returned.This is exactly what I need. The problem - Now execute the script below.
TRUNCATE TABLE TEST
TRUNCATE TABLE TEST2
insert test values(4,4,'d','02/06/2004')
insert test values(4,4,'d','02/01/2004')
insert test2 values(4,4,'d','02/06/2004')
insert test2 values(4,4,'d','02/01/2004')
--Now when I execute script B two rows are returned which is not what I want. Since the rows are identical no row should be returned. So depending on what column changes (col2 or col3), I have to alter the script. I seek advise on the method to calculate checksum. Again the PK is ID and Col1 only.
Thanks

Checksum Not Working
Jul 23, 2005I'm developing a stored procedure to run an update based on valuesentered into a .Net web form. I want to capture the chceksum of therow when it is displayed on the form then validate that when the updateis exec'd. Simple enough logic, eh? The problem is when I try to usethe checksum(*) function, SQL server yells at me and says that it isn'trecognized. I'm using SQL Server 7, so wtf? I am not the admin of theserver and I'm skirting around SQL Server Enterprise Manager and usingany free utils, MS Access, and Visual Studio to maintain this db.ThanksAlex Jamrozek

Jan 24, 2008Hi,
I heard that page checksum enabled will reports errors occured in the log. That's good.
Currently we have DBCC PHYSICAL_ONLY run alone and CHECKTABLE on group of tables on different days. A suggestion came from a person is to turn off 'DBCC CHECK TABLE' and run only when checksum reports an error and continue running CHECKDB WITH PHYSICAL_ONLY as before.
Is this suggestion a best practice? Please also write few lines to say why it is wrong or wright.
Thanks and best regards

CHECKSUM && CHECKSUM_AGG In T-SQL
Sep 24, 2007Hi,
I recently researched on the CHECKSUM & CHECKSUM_AGG functions in T-Sql and found them really useful. However, I was skeptical that there are chances of these functions returning the same values for non-identical inputs. I just got on to the forums and found more than one unhappy folks writing about their experience with these functions.
I am designing a large database (warehouse) and found these functions tempting to implement for the sake of
using CHECKSUM for
- indexing long character fields
- multiple colums of the same table that would involve in a join and use the new checksum field instead
using CHECKSUM_AGG for
- I bulkcopy flat file soruce data into a character field of a table and to ensure that I am not loading the same file multiple times, I plan to use CHECKSUM_AGG( CHECKSUM( [FlatFileRecord] ) ) and verify that no two loads have the same output.
Can some body suggest if I can trust these methods for my purpose?
Many thanks in advance!!
Thanks,
Harish
Checksum Storage
Feb 18, 2008it sounds like a column can be added to each row in a table that is the checksum or binary_checksum of an expression. How many bytes do each of these occupy? Does the answer depend on the number and/or length of items in the expression?

Need Help With Checksum Procedure
May 11, 2006Morning Campers,
I have two tables src_monthly_terrrier and src_weekly_terrier. Both of these tables consists of 10+ columns. As the table names probably suggest, I import weekly data into one and monthly data into another.
All the source data comes from an Excel spreadsheet via straight Import Data procedure. The only guaranteed change on a weekly and monthly basis is that one of the columns in each table named src_date will obviously have the data value for whichever month or week's data it relates to.
I understand that through 'SQL Server Business Intelligence Development Studio' I can create an 'Intergrated Services' package that will import the spreadsheet details for me. I might be going the long way around this, but it was my intention to bring in all the data and then run a couple of 'INSERT INTO' Stored Procedures.
My biggest issue / vunerability I have is that there is no error checking of the data on the way in to ensure that it has not already been imported. What I was thinking I could do to resolve this was to create a Checksum field comprising of a number of different columns (incl src_date) and then somehow write something that will look at the values of each intended imported row and then work out whether a duplicate checksum was found in the target table and then rejected the import routine as Duplicate Data Found (or something similar) and move onto the next stored procedure.
My problem is two fold, one I have no idea how to create said checksum and two no idea where to begin on coding a procedure etc that looks to see if the value already exists etc etc.
I have looked up checksum creation on the net and there appears to be plenty of resource to explain how to create one, so I guess my main question is, Where do I start when it comes to writing some code that will do the check of the checksum before the importation routine begins (or at least the Insert Into procedures.
I would truly appreciate anyone's help on this. In the meanwhile I am off to learn how to create them.
I would like to add, if anyone sees this as a bad idea, then please speak up.
Thanks in Advance
CHECKSUM() Of Binary Data

CHECKSUM Replacement For IMAGE And TEXT
Aug 22, 2006With this discussion here http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=70328
I started to thinkn about Microsoft really calculated checksum value.
This code is 100% compatible with MS original. That is, the result is identical.
You can use it "as is", or you can use it to see that MS function does not produce that unique values one could expect.
With text/varchar/image data, call with SELECT BINARY_CHECKSUM('abcdefghijklmnop'), dbo.fnPesoBinaryChecksum('abcdefghijklmnop')
With integer data, call with SELECT BINARY_CHECKSUM(123), dbo.fnPesoBinaryChecksum(CAST(123 AS VARBINARY))
I haven't figured out how to calculate checksum for integers greater than 255 yet.CREATE FUNCTION dbo.fnPesoBinaryChecksum
(
@Data IMAGE
)
RETURNS INT
AS
BEGIN
DECLARE@Index INT,
@MaxIndex INT,
@SUM BIGINT,
@Overflow TINYINT
SELECT@Index = 1,
@MaxIndex = DATALENGTH(@Data),
@SUM = 0
WHILE @Index <= @MaxIndex
SELECT@SUM = (16 * @SUM) ^ SUBSTRING(@Data, @Index, 1),
@Overflow = @SUM / 4294967296,
@SUM = @SUM - @Overflow * 4294967296,
@SUM = @SUM ^ @Overflow,
@Index = @Index + 1
IF @SUM > 2147483647
SELECT @SUM = @SUM - 4294967296
RETURN @SUM
ENDActually this is an improvement of MS function, since it accepts TEXT and IMAGE data.CREATE FUNCTION dbo.fnPesoTextChecksum
(
@Data TEXT
)
RETURNS INT
AS
BEGIN
DECLARE@Index INT,
@MaxIndex INT,
@SUM BIGINT,
@Overflow TINYINT
SELECT@Index = 1,
@MaxIndex = DATALENGTH(@Data),
@SUM = 0
WHILE @Index <= @MaxIndex
SELECT@SUM = (16 * @SUM) ^ ASCII(SUBSTRING(@Data, @Index, 1)),
@Overflow = @SUM / 4294967296,
@SUM = @SUM - @Overflow * 4294967296,
@SUM = @SUM ^ @Overflow,
@Index = @Index + 1
IF @SUM > 2147483647
SELECT @SUM = @SUM - 4294967296
RETURN @SUM

CHECKSUM , Produces Same Hash For Two Different Inputs. Is This Right?
Jul 25, 2007Hi,
We are using binary_checksum in some of instead of update trigger. The problem came into the knowledge when update falied without raising any error. We came to know after research that checksum returns same number for two different inputs and thats why update failed.
We are using following type of inside the trigger.
UPDATE [dbo].[Hospital]
SET
[HospitalID]= I.[HospitalID],
[Name]= I.[Name],
[HospitalNumber]= I.[HospitalNumber],
[ServerName] = I.[ServerName],
[IsAuthorized]= I.[IsAuthorized],
[IsAlertEnabled]= I.[IsAlertEnabled],
[AlertStartDate]= I.[AlertStartDate],
[AlertEndDate]= I.[AlertEndDate],
[IsTraining]= I.[IsTraining],
[TestMessageInterval]= I.[TestMessageInterval],
[DelayAlertTime]= I.[DelayAlertTime],
[IsDelayMessageAlert]= I.[IsDelayMessageAlert],
[IsTestMessageAlert]= I.[IsTestMessageAlert],
[IsUnAuthorizedMessageAlert]= I.[IsUnAuthorizedMessageAlert],
[IsWANDownAlert]= I.[IsWANDownAlert],
[IsWANUpAlert]= I.[IsWANUpAlert],
[CreateUserID]= Hospital.[CreateUserID],
[CreateWorkstationID]= Hospital.[CreateWorkstationID],
[CreateDate]= Hospital.[CreateDate] ,
/* record created date is never updated */
[ChangeUserID]= suser_name(),
[ChangeWorkstationID]= host_name(),
[ChangeDate]= getdate() ,
/* Updating the record modified field to now */
[CTSServerID]= I.[CTSServerID]
FROM inserted i
WHERE
i.[HospitalID]= Hospital.[HospitalID]
AND binary_checksum(
Hospital.[HospitalID],
Hospital.[Name],
Hospital.[HospitalNumber],
Hospital.[ServerName],
Hospital.[IsAuthorized],
Hospital.[IsAlertEnabled],
Hospital.[AlertStartDate],
Hospital.[AlertEndDate],
Hospital.[IsTraining],
Hospital.[TestMessageInterval],
Hospital.[DelayAlertTime],
Hospital.[IsDelayMessageAlert],
Hospital.[IsTestMessageAlert],
Hospital.[IsUnAuthorizedMessageAlert],
Hospital.[IsWANDownAlert],
Hospital.[IsWANUpAlert]) !=
binary_checksum(
I.[HospitalID],
I.[Name],
I.[HospitalNumber],
I.[ServerName],
I.[IsAuthorized],
I.[IsAlertEnabled],
I.[AlertStartDate],
I.[AlertEndDate],
I.[IsTraining],
I.[TestMessageInterval],
I.[DelayAlertTime],
I.[IsDelayMessageAlert],
I.[IsTestMessageAlert],
I.[IsUnAuthorizedMessageAlert],
I.[IsWANDownAlert],
I.[IsWANUpAlert]) ;
Here is the checksum example which produces same results for two different input.
DECLARE @V1 VARCHAR(10)
DECLARE @V2 VARCHAR(10)
SELECT @V1 = NULL, @V2=NULL
SELECT binary_checksum('KKK','San Jose','1418','1418SVR ',0,1,@V1,@V2,0,30,180,1,0,1,1,1),
binary_checksum('KKK','San Jose','1418','1418SVR ',1,1,@V1,@V2,0,30,180,1,1,1,1,1)
Lookat the two binary_checksum above, they are different and should not match, but they both return same value.
Can someone please provide some info on these.
SQLIS Checksum Install Problems
Mar 22, 2007For detecting delta records, I'm a big fan of SQLIS' checksum transform. I'm having difficulty in it's install on my current machine, however. After the installation and the new transform is added to my DataFlow toolbox... I can't open the UI for the transform to define the checksum. Instead, I get the following error:

PAGE_VERIFY Setting CHECKSUM - How To Detect?
Aug 30, 2006
Does anyone know how to detect the CHECKSUM setting of the PAGE_VERIFY database option (2005 only)?
BOL (ALTER DATABASE) includes the following statement:
PAGE_VERIFY { CHECKSUM | TORN_PAGE_DETECTION | NONE }
The current setting of this option can be determined by examining the page_verify_option column in the sys.databases catalog view or the IsTornPageDetectionEnabled property of the DATABASEPROPERTYEX function.
However, there is no column named page_verify_option in the view sys.databases, and DATABASEPROPERTYEX('IsTornPageDetectionEnabled') does not discriminate between the settings CHECKSUM and NONE (it returns 0 for both)!

Using A Scalar Valued Function As A Parameter Of A Table Valued Function?
Feb 1, 2006Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't...
I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it.
So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need.
Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like:
DECLARE @table table@table=EXEC sp_pkeys MyTable
That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great.
Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out...
SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT)
Syntax Error. Ugh. Eventually, I even try:
SELECT *FROM Split(substring('abc,def',2,6),DEFAULT)
Syntax Error.
Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function?
SELECT *FROM Split('bc,def',DEFAULT) works just fine.
So my questions are:
Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it?
Is there any way to pass a scalar-valued function as a parameter into a table-valued function?
Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround:
DECLARE @tmp varchar(8000)
SET @tmp=(SELECT dbo.fn_pkeys('MyTable'))
SELECT *
FROM Split(@tmp,DEFAULT)
