Database Change In Batch Update SQL Script
Oct 31, 2007
I used "OLE DB Command"(row by row) for update but because i found that very very slow i decided to try batch update. I check what is for insert and what is for update and those things that are for update i save to temp table. Then i run this:
update [ODS].[dbo].[Adres]
SET
[MutatieDatumEinde] = stAdres.MutatieDatumEinde,
[StraatNaam] = stAdres.StraatNaam,
[HuisNummer] = stAdres.HuisNummer,
[HuisNummerToevoeging] = stAdres.HuisNummerToevoeging,
[Postkode] = stAdres.Postkode,
[Plaats] = stAdres.Plaats,
[Land] = stAdres.Land,
[IndicatiePTTAdresStandaard] = stAdres.IndicatiePTTAdresStandaard,
[KodeHerkomstAdres] = stAdres.KodeHerkomstAdres,
[VervalDatum] = stAdres.VervalDatum,
[BronODS] = stAdres.BronODS
from
[ODS].[dbo].[Adres] oAdres
inner join [M2O_Stage].[dbo].[ODS_Adres] stAdres
on oAdres.InstNr = stAdres.InstNr and
oAdres.TypeAdres = stAdres.TypeAdres and
oAdres.MutatieDatumAanvang = stAdres.MutatieDatumAanvang
where stAdres.IsInsert = '0'
I run this as an "execute sql task". Everything is running as it should and speed is incomparable, but.. i have problem to make this generic... what i mean is.. db names will change.
How can i make db names dynamic here ?
p.s. i just got idea .. i could probably make dynamic sql statement in script component and then run it there... but does anyone have a better idea ?

I have a collection of around 16000 records, and have been trying to find the best way to update the information in the DB. I have done alot of reading about both BulkCopy and Batch Update, but haven't come to any clear solutions as to which performs better. I am not doing any inserting, just getting a dataset from the DB, changing the values, them want to update the Db again. Thanks for any help. Mick

Can anyone help a beginner with some T-SQL which runs as a scheduled stored procedure to update a table with is then accessed via an ASP web application.
I have a table called Loans which contains a calculated column which will indicate in days if a loan item is late and also each row has a charges column to reflect a charge for late returns.
In a seperate table I have a charge per day for late returns. I read this into a variable @LateCharges
I'd like to consutruct some T-SQL to scan through the Loans table and for every row where Status is not 'Returned' I woule like it to update the charges column based on the DaysLate column*@Latecharges
Any help much appreciated.

The following code is a part of my stored procedure MySP. I would like to update Users table with input variable @userIDs which has the following format:
101, 102, 103
I got the error message:
Syntax error converting the varchar value '101, 102, 103' to a column of data type int.
Obviously, UserID has datatype int. How can I write this SP?
CREATE PROCEDURE dbo.MySP

UPDATE Users SET IsActive = 1 WHERE UserID IN (@userIDs)

hello .
i have a grid for a table that gets updated with recordset.updatebatch
for a multi-user application.
the problem is that some of the table fields have to be unique
now imagine the next situation.
user A opens the form
user B opens the form
user A writes '1000' in the unique field
user A saves the recordset with updatebatch
user B writes '1000' in the unique field
user B saves the recordset with updatebatch
now there will be two records with the field '1000' !
how can i avoid this ?
i cannot check for unique during the update event of the grid
because it should check during the time it is saving and not
when it is just entering data without having updated the recordset
thanks !

Is there a way to create a Batch file that will run an Update Statement and schedule it to run?I've used bcp to extract data to a txt file before, but i'm not sure if an Update can be performed.I'm using SQL Server 2008 R2 Express Edition so i don't have Server Agent available.

I want to make data changes in read_only database , that's why i must set database read_write. While database is at read_write mode, i want to be sure that no one makes change in database.
For this aim, i write the code below, but i suspect that after setting the database read_write, till the setting database
single_user ,is it possible get DML script from another user. Is the code below enough for this operation. Or is there another way?
Reminding: Read_only database can not be set single_user mode. That's why, first you must set database read_write.
The code;
use master
alter database xxx set read_write
with rollback immediate
alter database xxx set single_user
with rollback immediate
use xxx
update tablexxx set columnxxx=yyy
use master
alter database xxx set read_only
with rollback immediate
alter database xxx set multi_user
with rollback immediate

I have create a batch file, that creates an ODBC then updates the application datasource key in the registry to the new system dsn name.
The problem is that the new DSN doesn't work when i try and connect the application...but if i had manually created the odbc source the app connects as expected... i have checked the registry and there is no difference between the two dsns created...but the application throws IM002[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified after i have also changed the applications registry key to point to the new database.
Now the interesting things to note are that when i re-create the odbc to the old server and database (sql 2000) by batch file it works fine. The new ODBC is linking to a sql 2005 database, but it is still using the 2000 drivers and when i manually created it, it worked also.
Another interesting thing is that if i go into the odbc dsn and click configure, go through and test the connection it works fine... after i close this i then retry the application and it opens correctly...
I need this to be automated with no manual intervention, as this will be added to a large group of users login scripts!
Any help greatly appreciated.
My batch file code is as below:
ODBCCONF.exe CONFIGSYSDSN "SQL Server" "DSN=RMS Live 2005 | SERVER=d-db99sql2005| Trusted_Connection=Yes | Database=RMS-Livedb"

Hello everyone,I have around 20 reports in an ASP web-application which connects to aSQL Server 2000 dB, executes stored procedures based on inputparameters and returns the data in a nice tabular format.The data which is used in these reports actually originates from a 3rdparty accounting application called Exchequer. I have written a VBapplication (I call it the extractor) which extracts data fromExchequer and dumps the same into the SQL Server dB every hour. Therunning time for the extractor is an average of 10 minutes. Duringthese 10 minutes, while the extractor seems to run happily, my ASPweb-application which queries the same dB that the extractorapplication is updating becomes dead slow.Is there anyway I can get the extractor to be nice to SQL Server andnot take up all its resources so that the ASP web-application users donot have to contend with a very very slow application during thosetimes?I am using a DSN to connect to the dB from the server that runs theweb-application and well as the other server which runs extractor.Connection pooling has been enabled on both (using the ODBCAdministrator). The Detach Database dialog gives me a list of openconnections to the dB. I have been monitoring the same and I havenoted 10-15 open connections at most times, even during the executionof extractor.All connection objects in the ASP as well as VB applications areclosed and then set to nothing.This system has been in use from 2002. My Data file has grown to 450MBand my Transaction Log is close to 2GB. Can the Transaction Log be aproblem. For some reason, the size of the Transaction Log does not godown even after a complete dB backup is done. Once a complete dBbackup is done, doesn't the Transaction Log lose its significance andcan be actually deleted? Anyway this is another post I'm doing todayto the group.In the extractor program,1) I create a temporary table2) I create an empty recordset out of the table3) I loop through the Exchequer records using Exchequer's APIs, addingrecords into the recordset of the temporary table as I go along.4) I do an UpdateBatch of the Recordset intermitently5) I open an SQL Transaction6) I delete all records from the main table7) I run a INSERT INTO main_table SELECT * FROM #temp_table8) I commit the transactionI hope that the information is sufficientThanksSam

Hi,
I have two tables (test, test_invoice) both filled in automatically; what i need to do is update whenever there has been a change in table test_invoice (literally new record with date of invoice).
two tables:
create table test
(id_customer int not null
,date1 smalldatetime
,date2 smalldatetime
,flag char(3)
)
ALTER TABLE [dbo].[test] ADD
CONSTRAINT [PK_test] PRIMARY KEY CLUSTERED
(
[id_customer]
) ON [PRIMARY]
GO
insert into test (id_customer, date1, date2, flag) values (2323, '2008-2-23', '', 'Yes')
insert into test (id_customer, date1, date2, flag) values (2325, '2008-2-25', '', 'No')
create table test_invoice
(id_customer int not null
,date_invoice smalldatetime
)
ALTER TABLE [dbo].[test_invoice] ADD
CONSTRAINT [PK_test_invoice] PRIMARY KEY CLUSTERED
(
[id_customer]
) ON [PRIMARY]
GO
insert into test_invoice (id_customer, date_invoice) values (2325, '2008-3-2')
insert into test_invoice (id_customer, date_invoice) values (2329, '2008-3-5')
so how do i make this update happening automatically whenever there is a new record in test_invoice
update t
set t.date2 = ti.date_invoice
from
test as t
inner join test_invoice as ti
on ti.id_customer = t.id_customer
I'd say IF is missing in front of the update sentance...? :-)
Thank you

Hi All,
I have following issue.
Currently, whether values from parameters (there are 20 parameters) passed to one stored procedure will have following script to handle
INSERT INTO log table for all value from TABLEA where ID=@ID
UPDATE TABLEA SET COLUMNA=@COLUMNA and etc,STATUSDATE=getdate() WHERE ID=@ID
However, this creates the problem when the user submit same records, 40 times a day. As a result, statusdate is being updated frequently. This has created the problem in our daily report.
Thus, the user requested to have checking on each column. If any of column has different value, then the update can be done.
what i am thinking at this moment is
BEGIN TRAN
INSERT INTO log table for all value from TABLEA where ID=@ID
INSERT INTO TEMP TABLE (CHANGE_IN_COLUMNA)
UPDATE TABLEA SET COLUMNA=@COLUMNA OUTPUT CASE WHEN DELETED.COLUMNA <> INSERTED.COLUMNA THEN 'YES' ELSE 'NO END and etc,STATUSDATE=getdate() WHERE ID=@ID
IF ANY COLUMN HAS YES VALUE THEN COMMIT TRAN
OTHERWISE ROLLBACK TRAN
Do you think that this is a good solution?
Thanks for the assistance

This is on the uniqueidentifier column. Both tables are on the same database and have the same COLLATE Latin1_General_CI_AS.
But my plain update and insert results are all upper case.
Then when I tried to force by using
Insert (cols1, cols2) Values (source.col1, source.col2) COLLATE Latin1_General_CI_AS
and
Update set target.col1=source.col1, target.col2=source.col2 target.col1=source.col1 COLLATE Latin1_General_CI_AS
I got
Msg 447, Level 16, State 0, Line 32
Expression type uniqueidentifier is invalid for COLLATE clause.

I've been struggling with this issue,
1) Test--FolderName (This Test folder name should use as a database name for below sub folders)
a)Create--Sub Foldername
i)create.sql
b)Alter---Sub FolderName
i)Alter.sql
c)Insert---Sub FolderName
i)Insert.sql
[Code] .....
The scripts need to be run in order. So script one needs to run first folder in that sub folders after that next second folders etc..
Is there a way to create a bat file that automatically runs all these scripts, in order against, the databases they need to?
The databases that they need to run against have the name of the database at the beginning of the name of the folder.

I need to update a large table, about 55 million rows, without filling the transaction log, in the shortest time as possible. The goal is to alter the table and change the data type for Text column from VARCHAR(7900) to NVARCHAR(MAX).
Since I cannot do it with an ALTER TABLE statement (it would fill up the transaction log) I'm thinking to:
- rename column Text in Text_OLD
- add Text column of type NVARCHAR(MAX)
- copy values in batches from Text_OLD to Text
The table is defined like:
create table DATATEXT(
rID INTEGER NOT NULL,
sID INTEGER NOT NULL,
pID INTEGER NOT NULL,
cID INTEGER NOT NULL,
err TINYINT NOT NULL,
[Code] ....
I've thought about a stored procedure doing this but how to copy values in batch from Text_OLD to Text.
The code I would start with (doing just this part) is the following, but maybe there are more efficient ways to do it, or at least there's a better way to select @startSeq in the WHILE loop (avoiding to select a bunch of 100000 sequences and later selecting the max).
declare @startSeq timestamp
declare @lastSeq timestamp
select @lastSeq = MAX(sequence) from [DATATEXT] where [Text] is null
select @startSeq = MIN(Sequence) FROM [DATATEXT] where [Text]is null
BEGIN TRANSACTION T1
WHILE @startSeq < @lastSeq
[Code] ....

I have located a bug in the functions cdc.fn_cdc_get_net_changes_<capture_instance> generated when you enable cdc on a table. This bug can be triggered if 2 rows are created in the _CT table having the same values for the __$start_lsn, __$seqval and the table's key column(s). From research on the internet I have found such rows can be created by a "deferred update": a single update statement in which a column that is part of a unique constraint is updated.
In order to report the bug with Microsoft I need to create a complete series of steps-to-reproduce. But even though the situation happens several times a day in our production environment, I have not yet been able to reproduce it in my test environment.I need a single update statement (plus maybe some steps in advance) that make that the log reader inserts 2 rows into the _CT table, one with __$operation = 1 (delete) and another with __$operation = 2 (insert) as opposed to the single row with __$operation = 4 that it inserts for a normal update. Below is the script I have so far to create a fresh database, enable cdc, create a test table, insert some data and update this data.
I would have liked the last update statement to be handled as a "deferred update". However in all of my tests the log reader just simply inserts a single row into the cdc.dbo_NETTEST_CT table.how to reproduce the situation where I get the 2 rows with __$operation 1 and 2 from a single update statement instead of the single row with __$operation = 4.
CREATE DATABASE [cdcnet]
CONTAINMENT = NONE

How to maintain Database User Permissions when copying the Database from One SQL Server to another(Either through backups or sp_detach). The reason is the login sid is different in the target server and as a result the database user is not able to map to the login existing in the target server. The only way I can correct this is through dropping and recreating the user's again and assign the permissions, or change the system catalog - sysusers to remap the login to the user in the database.
I do not wish to use the sp_addalias as it is available only for backward compatibility.
Is there a better way of doing this ?

hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.
