Begin Commit Transactions
Mar 14, 2001
Many times i write stoted procedures with transaction blocks.
I have delete a row after begin transaction and in continue i
read from table the select statement get back the deleted row:
begin tran
delete mytable
where id = @myid
and seqid = 3
select sum(balance)
from mytable
where id = @myid
............
...............
commit tran
.... OR
rollback tran
the sum(balance) function has calculate the balance of row 3
I use SQL 7.0
Thanks

hi,
I have wriiten the code cn.Open();
SqlCommand CmdInsertAct1 = new SqlCommand("insert into EmpActuals(PayrollGroup,GroupName,PaymentName,PaymentValPer,Percentage) values('" + txtPayBatch.Text.ToString() + "','" + txtPayBactName.Text.ToString() + "','" + txtActName1.Text.ToString() + "','" + txtActAmt1.Text.ToString() + "','" + ddlAct1.SelectedValue + "' )", cn);SqlCommand CmdInsertAct2 = new SqlCommand("insert into EmpActuals(PayrollGroup,GroupName,PaymentName,PaymentValPer,Percentage) values('" + txtPayBatch.Text.ToString() + "','" + txtPayBactName.Text.ToString() + "','" + txtActName2.Text.ToString() + "','" + txtActAmt2.Text.ToString() + "','" + ddlAct2.SelectedItem.Value + "')", cn);

No I did not write this below, this is from a vendor, I used profiler and I believe their SP is causing a blocking problem on their vendor supplied DB. It thought at the least always have a begin end or a begin trans commit trans. ANy quick opinions greatly appreciated

Hi
I have an overnight process that takes transactions from an external system & applies updates to a single db table. Other processes may be active on the db but none touch the tables I'm using. I cannot guarantee the volume of source transactions (may vary from 100s to 100,000s).
My question is should I protect the update within a begin+commit/rollback or should I have a recovery procedure to run in the event of failure (that would delete any rows added to my db table)? (My preference is to do the latter - so I'm really looking for any reasons why I shouldn't take this approach).
Thanks.

Hello,
First of all, this is my first time using SQL SERVER 2005 express, before that i'm using POSTGRESQL database.
I would like to know how what's the equivalent command for "BEGIN","ROLLBACK","COMMIT", these are the POSTGRESQL COMMAND use to start transaction, rollback transaction and commit transaction.
Example when i use this kind of command is . I need to insert data into 3 table. before insert into table1, i issue "begin", start to insert data into table1, if table1 no error, then i proceed to table 2 and table3. if table2 and table3 no error. then issue "commit" to commit the changes. but if any error happen between table1 and table 2 or table 2 and table3, i will issue "rollback" to roll any changes that i make to table1, table2 and table3.
Maybe some one can teach me how to achieve using SQL SERVER 2005 EXPRESS.
Thanks and Regards.

I am getting an exception. And i don't know whether this exception is from the C# coding or SQL SERVER."Cannot roll back InsertRxs. No transaction or savepoint of that name was found.Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 0, current count = 1.A transaction that was started in a MARS batch is still active at the end of the batch. The transaction is rolled back."

I have a series of questions about SSIS and transactions. The answers to these questions are probably so obvious that I can't see them, so please feel free to just point out what it is that I'm missing. My transaction-processing experience is very low-level, so I'm probably just not seeing how it's done at the high level of SSIS.
The first question is one that I may know the answer to, so please confirm:
Consider a package with TransactionOption set to Supported. It contains a single Execute SQL Task with TransactionOption set to Required. Is it true that if that Execute SQL Task succeeds, that the transaction commits, and that if the task fails, the transaction rolls back?
Consider another package with TransactionOption set to Supported. It contains a Sequence Container with TransactionOption set to Required. That container contains our same Execute SQL Task, but that is joined to a script task by a "success" precedence constraint. The script task simply returns Dts.Results.Failure. Is it the case that the transaction will roll back? That is, is it truly a simple failure result that would initiate the rollback?
If a DataFlow Task is the one that is set to Required, does that mean that every transactional operation within that task will commit in a single transaction? For instance, if I'm inserting five rows for each input record from a flat file, and if my flat file has 1000 records in it, will I see a single transaction with 5,000 rows?
Thanks for your patience!

Hope this is the right forum. I'm using Transaction=required on a page which inserts on multiple tables, 2 of which have a foreign key relationship. All works fine as log as I don't input erroneous data. However, I have a range check in the code, and if the range is exceeded, an exception is thrown and the transaction fails using ContextUtil.SetAbort(). I then correct the data and try to save and get a Foreign key contraint error. I have debugged and the primary key table seems to be carrying out the insert ok (I'm retreiving the key at that point, and can see it). But when I use the key in the child table it fails and cites the foreign key relationship.
I suspect that having the same data for the primary key table 2nd time around means it doesn't think it has to commit????
Grateful for any help. I'm using Sqlserver 2005 by the way.

I have a update trigger. In this trigger I need to insert few records in 3 tables. If error comes in any of these inserts then previous inserts to get committed. This trigger was written in Sybase and it was possible to create transaction and commit the transactions.

I have to modify the table structure where the table have a lot of data already. The log is getting full due to uncommitted transactions, there is a lot of data being updated in large bulks, not all of the transactions are committed, the update task cannot be completed.
However, there is no more spare disk space for it to commit the transaction. Anyone can help?

If application code controls all transaction processing to SQL Server, so it starts a transaction, does any commit or rollback on teh application side, how does that actually work ON SQL Server 2005... Meaning, If the app passes in a isolation level of Repeatable Read, and the database default is different, how can I see what is being used, as a DBA? Can I see any of that via Profiler? can I see when those commits/rollbacks are issued from teh application. They are not sending in "SQL" commit/rollback transaction commands. It's built-in to their architecture to control all that... How can I see what's happening on the database if these are not SQL commands for transaction handling? and how does that work, to start a transaction on the app side, and hold locks etc, on SQL Server if normal SQL Server commands are not being sent? If anyone can point me at decent references to read on that, thanks! Bruce

Hi
How do I make use of begin transaction and commit transaction in SSIS.
As am not able to commit changes due to certain update commands I want to explicitly write begin and commit statements. but when i make use of begin and commit in OLEDB commnad stage it throws an error as follows:
Hresult:0x80004005
descriptionyntax error or access violation.
its definately not an syntax error as i executed it in sql server. also when i use it in execute sql task out side the dataflow container it doesnt throw any error but still this task doesnt serve my purpose of saving/ commiting update chanages in the database.
Thanks,
Prashant

I had thought that if any statement failed within a BEING TRANS .. COMMIT TRANS block, then all the statements would be rolled back. But I am seeing different behavior (SQL Server 2000 8.00.2039)
For instance, run these statements to set up a test:
--DROP TABLE testTable1
--DROP TABLE testTable2
CREATE TABLE testTable1 (f1 varchar(1))
CREATE TABLE testTable2 (f1 varchar(1))
CREATE UNIQUE INDEX idx_tmptmp ON testTable1 (f1)
insert into testTable1(f1) values ('a')
So table testTable1 has a unique index on it..
Now try to run these statements:
--DELETE FROM testTable2
BEGIN TRANSACTION
insert into testTable1(f1) values ('a')
insert into testTable2(f1) values ('a')
COMMIT TRANSACTION
SELECT * FROM testTable2
..the first insert fails on the unique index.. but the second insert succeeds. Shouldn't the second insert roll back? How can I make two operations atomic?

Hi,
I want to rollback my t-sql if it encounters an error. I wrote this code:
begin tran mytrans;
insert into table1 values (1, 'test');
insert into table1 values (1, 'jsaureouwrolsjflseorwurw'); -- it will encounter error here since max value to be inputted is 10
commit tran mytrans;
I forced my insert to have an error by putting a value that exceeds the data size. However, I didn't do any rollback. Anything i missed out?

I'm receiving the below error when trying to implement Execute SQL Task.
"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'
I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.
Anyone know of the reason?

Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated

Hi All,
I am basically a newbie to networking. My manager gave me backoffice and said "here, install this".
I have NT and the service pack installed............but now I want to install SQL.........where do I begin?
We are installing NT, and SQL etc on drive C: of the server, and the database (we use Goldmine for database software/contact management), is installed on drive D:
anyone point me in the right direction????
web pages, books, newsgroups...........any help is greatly appreciated.
Thanx In Advance.

I can't see why i get this error :
Server: Msg 156, Level 15, State 1, Procedure fn_GetSpouseFrSecondPerson, Line 49
Incorrect syntax near the keyword 'BEGIN'.
from this code :
if (@flags | @LN_MATCH)
BEGIN
set @nPos = charindex(@sOwnerslast, @sSecondperson)
set @sSpouse = left(@sSecondperson, @nPos - 1)
END
(whole listing is below for the curious)
the problem is not my boolean test; if i just replace it with TRUE, the same results.
Only by commenting out the BEGIN ... END block eliminates the error.
Is there some esoteric rule about which commands or how much or how little can be in a code block?
I'm stumped...
Thanks,
Joe

If you are set up for AutoCommit why would you or should you set a explicit transaction? I have noticed that in some called stored procudures from a "container" stored procedure. (Hope I got that right) that in the called stored procedure a Begin tran is used. Can anyone help with the why and what fors? It seems to me that you want to let SQL Server handle this becuase of the danger of leaving out a Commit or Rollback? But thats me. I may be very wrong? Thanks.

I need to copy two large tables from one database into another, via the internet. I haven't worked out exactly how yet, but the first issue which has occurred to me is that by the time the first table has been exported (via a SELECT clause?) into a suitable file, the second table (to which it is related) will be out of sync. So, how do I ensure that I end up with a snapshot of the two tables, perfectly in sync with each other? I know that BEGIN/END TRANSACTION makes sure that UPDATES to tables remain in sync, but will it work just for SELECT statements?

hello, I have a big problem with a script.. some instructions seems to be not executed. I don't understand. If I execute line perline it's ok - but the entire block no.
Explain me and find the solution:
IF NOT EXISTS ( SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'ACS_ACL'
AND COLUMN_NAME = 'ZoneUId' )
BEGIN
ALTER TABLE dbo.ACS_ACL ADD ZoneUId T_UID;
UPDATE dbo.ACS_ACL SET ZoneUId = '1' WHERE ZoneUId IS NULL;
print 'end of script'
END
result:
Msg 207, Level 16, State 1, Line 9
Invalid column name 'ZoneUId'.
the error is on line:
UPDATE dbo.ACS_ACL SET ZoneUId = '000000001' WHERE ZoneUId IS NULL;
how is is possible because the preceding line is
ALTER TABLE dbo.ACS_ACL ADD ZoneUId T_UID;

Could someone tell me if this is the correct way to begin and commit a transaction:
CREATE procedure AddTitle
@title varchar(255),
@descriptions varchar(255),
@mediaId int,
@quantityowned int,
@classificationid int
AS
BEGIN Tran TranStart
Set NOCOUNT ON
declare @titleid int --declaring the titleid
INSERT INTO Titles(title, [descriptions])
values(@title,
@descriptions)
set @titleid = SCOPE_IDENTITY() --grabbing the id to be placed in the other table
INSERT INTO Resources(titleid,mediaid,quantityowned)
values(@titleid,
@mediaid,
@quantityowned)
insert into titleclassification(titleid, classificationid)
values(@titleid, @classificationid)
select @titleid as titleid -- return to caller if needed
Commit Tran Transtart
GO
Where would I put rollback transaction? Do I need it?
Thanks!

I have writen a small program in a Query window that runs fine if I hilight and run small chuncks. (I have listed the statements with out the clauses so it is more easly viewed here.)
The problem is if I simply execute the Query window I get massive errors that don’t make sence. I am guessing I need some GO and BEGIN/END statements? But I don’t know where I should use them.
I would really appreciate a few pointers so I can just run the Query window.
drop table SourceFile
drop table ReferenceFile
SELECT TOP
INTO SourceFile
FROM
SELECT TOP
INTO ReferenceFile
FROM
-- test data
INSERT ReferenceFile
(AddressCleanedPK, New_First_Name, New_Last_Name, New_Address, Phone, Zip)
values ()
INSERT SourceFile
(AddressCleanedPK, New_First_Name, New_Last_Name, New_Address, Phone, Zip)
values (22)
-- test data
drop table MATCHTEST
SELECT TOP 1 AddressCleanedPK, New_First_Name, New_Last_Name, New_Address, Phone, Zip
INTO MATCHTEST
FROM AddressCleaned_npidata_20050523_20071112
DELETE MATCHTEST
ALTER TABLE MATCHTEST
ADD REF_ML VARCHAR(2)
INSERT MATCHTEST ()
SELECT
FROM ReferenceFile r
inner join SourceFile s
on s.New_Last_Name = r.New_Last_Name
select * from MATCHTEST

/*Subject: How best to use BETWEEN Begin and End Dates to find out if anemployeewas/is member of any group for a certain date range?You can copy/paste this whole post in SQL Query Analyzer or ManagementStudio andrun it once you've made sure there is no harmful code.I am working on an existing database where there is code that is usingBETWEEN logic and three different OR conditions to search for a user thathas worked between begin and end date parameters that you search for.For me the three WHERE conditions with the Begin and End dates are a littleconfusing so I would like to know if there's a better/simpler way to writethis.1- I have groups table with GroupID, Name2- I have employees table with EmployeeID, LastName, FirstName3- I have employeegroups table where the EmployeeID has the GroupID he/shewas/is a member of and from what Begin to what End dates.The employee can never be a member of two groups in any date interval.The employee always was/is a member of a group from a certain to a certaindate and then the next group he/she is a member of a group begins 1 dateafter the previous group membership's end date. Therefore If I worked from2006-01-01 to 2006-01-31 and then I changed group, well in this databasethenext group dates would begin at 2006-02-01 till an Open Ended default dateof2009-12-31.I can also be a member of a group for 1 day: 2006-05-05 to 2006-05-05Please continue to read below at the bottom.*/USE tempdbGOIF EXISTS (SELECT * FROM sysobjects WHERE name = 'EmployeeGroups' AND xtype= 'U')BEGINTRUNCATE TABLE EmployeeGroupsDROP TABLE EmployeeGroupsENDGOIF EXISTS (SELECT * FROM sysobjects WHERE name = 'Groups' AND xtype = 'U')BEGINTRUNCATE TABLE GroupsDROP TABLE GroupsENDGOIF EXISTS (SELECT * FROM sysobjects WHERE name = 'Employees' AND xtype ='U')BEGINTRUNCATE TABLE EmployeesDROP TABLE EmployeesENDGOCREATE TABLE dbo.Groups(GroupID int NOT NULL,Name varchar(50) NOT NULLCONSTRAINT PK_Groups PRIMARY KEY NONCLUSTERED(GroupID))GOCREATE TABLE dbo.Employees(EmployeeID int NOT NULL,LastName varchar(50) NOT NULL,FirstName varchar(50) NOT NULLCONSTRAINT PK_Employees PRIMARY KEY NONCLUSTERED(EmployeeID))GOCREATE TABLE dbo.EmployeeGroups(EmployeeID int NOT NULL,GroupID int NOT NULL,BeginDate datetime NOT NULL,EndDate datetime NOT NULL,CONSTRAINT PK_EmployeeGroups PRIMARY KEY NONCLUSTERED(EmployeeID,GroupID),CONSTRAINT FK_EmployeeGroups_Employees FOREIGN KEY(EmployeeID) REFERENCES Employees(EmployeeID),CONSTRAINT FK_EmployeeGroups_Groups FOREIGN KEY(GroupID) REFERENCES Groups(GroupID))GOINSERT Groups (GroupID, Name)SELECT 1, 'Group1' UNION ALLSELECT 2, 'Group2' UNION ALLSELECT 3, 'Group3' UNION ALLSELECT 4, 'Group4'GOINSERT Employees (EmployeeID, LastName, FirstName)SELECT 1, 'Davolio', 'Nancy' UNION ALLSELECT 2, 'Fuller', 'Andrew' UNION ALLSELECT 3, 'Leverling', 'Janet' UNION ALLSELECT 4, 'Peacock', 'Margaret' UNION ALLSELECT 5, 'Buchanan', 'Steven'GOINSERT EmployeeGroups (EmployeeID, GroupID, BeginDate, EndDate)SELECT 1, 3, '1990-01-01', '2004-10-15' UNION ALLSELECT 1, 4, '2004-10-16', '2004-10-16' UNION ALLSELECT 1, 1, '2004-10-17', '2099-12-31' UNION ALLSELECT 3, 2, '1999-11-15', '2002-02-22' UNION ALLSELECT 3, 4, '2002-02-23', '2099-12-31' UNION ALLSELECT 4, 3, '2006-05-17', '2099-12-31'GO--SELECT * FROM Groups--SELECT * FROM Employees--SELECT * FROM EmployeeGroupsDECLARE @EmployeeID INTEGERDECLARE @BeginDate DATETIMEDECLARE @EndDate DATETIMEPRINT 'First example of querying...'SET @EmployeeID = 1SET @BeginDate = 'Sep 18 2005 12:00:00:000AM'SET @EndDate = 'Sep 24 2006 12:00:00:000AM'-- This is the code logic being used in the database I am looking at.SELECT *FROM EmployeeGroupsWHERE EmployeeGroups.EmployeeID = @EmployeeIDAND ((EmployeeGroups.BeginDate <= @BeginDate AND EmployeeGroups.EndDate
