Force A Commit
Sep 3, 2007
Hi,
My data flow has several transformations:
1. Search an employee, if the employee already exists, update it, otherwise insert it.
2. Once the new employee is created, i have to get its id (with another search transformation )to update another table with it. This id is an autonumeric , thats the reason i have to get it once the record is inserted.
At this momment this second search transformation to get the assigned id for the new reacord doesnt find any employee... i suppose its because these new data is not commited in the database....
the question is, Its possible to force a commit?
Thanks!

I've a complex stored procedure, that makes a lot of insert, update,delete and so on.I would like to make some commits durint this sp, but of course theyare not "real" commit because who call the sp could decide for arollback.But I know that this commit has to be real. In fact, the transactionlog grows really too much during the execution.Is there a way to force a commit durint a sp ?thank you very much!

Microsoft SQL Server Management Studio Express
select @@trancount
begin tran
select @@trancount
use ProdNetPerfMon
select @@trancount
update Nodes set Caption = 'xxxx' where Vendor = 'yyyy'
select @@trancount
commit tran
select @@trancount
Executes as expected including trancount without errors.
Nodes.Caption is updated but reverts after a few minutes.

Do delete/update statements in MS SQL Server need a "commit" (or equivalent) run after them as they do in Oracle?

Hi ,
I've tried to switch MS-Sql/Server 6.5 on explicit_transactions
without success.
(set implicit_transaction on/off)
What is the exact syntax for doing that ?

Hi All,
I don't know MS-SQLserver internal system at all. I 've just used Oracle
a couple years ago and so in some cases (e.g using TP-monitor MTS or Tuxedo)
you can switch off the implicit transaction by using
the option AUTOCOMMIT ON/OFF.
How can switch off the implicit transaction system on MS-SQLServer ?
In advance thanks,
Herve

l also use the
begin transaction
select ........etc
commit
structure when l wrtite queries.My problem is that if l close the query analyser it asks me to commit transaction before l exit. Why?
How do you check for uncommitted trans and commit them?

I built this in SQL query analyzer to update all records with the 1/1/02 date:
update tbl.EMPPOS set EFFECT_DATE = '2005-01-01'
where EFFECT_DATE = '2002-01-01';
when I run the query it updates and shows records in the lower window, but the tbl isn't altered. What is wrong with my syntax ??
thanks,

I have an SSIS package that iterates through a thousand or so download text files, parses them and inserts the results into a database via a Stored procedure and an OLE DB Command.
For the most part this process works without any issues, yet I keep obtaining random errors on a DT_STR (500) column. I have reviewed the data extensively and this column - which is the same across all of the rows - does not appear to be any different.
The rest of the rows before and after the error rows all insert properly but these rows consistently fail in the OLE DB task with the following error:
[OLE DB Command [35549]] Error: An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E14 Description: "The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. The RPC name is invalid.".
When I inserted the rows into an errors table, I found that the error code, -1071607698, is not defined and the only thing I could find online was a reference to:
DTS_E_COMMANDDESTINATIONADAPTERSTATIC_UNAVAILABLE
which appears to be a DTS error and not an SSIS error.
I have added tasks to explicitly verify the length of the field and that field actually inserts without any issues into the error table - which has the exact same column definition as the target table.
I am at a complete loss as to how to proceed - does anybody have an idea?

when doing an 'update table set field1 = 'N',using sql query analyzer, is the update committed immediately? If it isn't commited can a 'rollback' be executed, and what is the format of the rollback command?

Hi,
I'm using an SQL Express database over a network, using a C# Express program. So I had to use pure SQL connections and commands instead of using Data Sources (couldn't find a way for it to work). In the program / DB I've got a couple of Master - Detail situations. Something like:
Product:
-----------
productID
(...)
Acessories:
----------------
acessID
(...)
ProductAcess:
--------------------
productID
acessID
So when inserting a new Product, I'll have to first insert the product (with product name, price, and so on) and once I get the product ID from the insert command, I'll insert the ProductAcess rows. I've found a problem in this though. If for some reason the insert of the product is successful, but the insert of ProductAcess fails, I've got a big mess in hands because I'll have a row in Product with no rows in ProductAcess (which shouldn't happen in my program scenario). I could solve this by deleting all rows from the DB which connected in someway to the product that failed to insert, but would be far better and correct if I used a commit command at the end of the insert commands to make sure only the right data would be inserted (saving time and resources). I use this all the time in Oracle databases, but don't know if it is possible in SQL Express... Is it? How? Thanks

I have several sets of code that need to delete rows from more than one database at a time. The rows are basically linked without being identified as having a foreign key. This means I issue two deletes. If one fails, especially the second one, there is no way to roll the first delete back.Can someone either point me to some code that enables me to link the deletions, allowing me to insure that both are successful or both do not occur. I cannot identify any fields on the secondary database table as specifically linked to the primary, as the secondary database is a storage medium for images, that may be linked to more than one different table.TIA for any opinions, options, etc. Tom

I first must delete any existing log for my current record.
Then verify that the "exec @res = gmw_updatesynclog..." has not failed and a delete log entry has been successfully written as verified by the gmw_updatesynclog's return of int 16.
If all is well then I incrment my counter and delete the record, here in testing I'm just updateing the activity code to del so I can find them, in live I'll just be deleting them.
--My error
Server: Msg 266, Level 16, State 2, Line 0
Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 1, current count = 2.
-- end my error
...excerpt from my proc and nested cursor....
------------------------------ begin calls to be deleted
if @rectype = 'C' and (len(rtrim(@notes))<20 or @notes is null)
begin transaction
delete gmtlog -- delete any older del log for this recid
where frecid = @recid
and fieldname = 'zzzDel'
and tableid ='"'
if @@error = 0 -- 0 or 1 rows affected...
exec @res = gmw_updatesynclog 'cal',@recid,'MASTER','D'
if @res <> 16 rollback transaction
goto endd --cleanup and fetch next record
if @res = 16 -- increment count_call_dels
set @count_call_dels = @count_call_dels +1
update cal -- update in test delete in live
set actvcode = 'DEL'
where recid = @recid
commit --transaction
------------------------------ end calls to be
... end excerpt...

Hi,
Reviewing the MSSQL process info screen, I am seeing the same process appear a numer of times. It is always the same, being
'IF @@TRANCOUNT > 0 COMMIT TRAN'
Sometimes, there can be up to a hundred of these processes (listed in the process info screen). They generally have a 'sleeping' status, but nonetheless, I would like to see these processes disappear if they are not being used.
I have checked in all of the stored procedures and triggers in the application, and none have this sql statement.
When I run profiler, I get these entries, but the profiler says they belong to either SQL Enterprise Manager or 'Microsoft Windows 2000 Operating System', and not to the application I am running.
Does anyone know where these transactions come from? Can I prevent these from appearing? If no, what is the impact (other than sql server having to maintain a connection).
Thanks,
Jim

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.

Hi
Need a help for the below req.
I have a SP which calls another SP with in a Cursor. The main SP updated two of the DB tables. Based on the data passed from main SP the nested SP updates another two table.
What I want at the end of loop the transaction will be committed. In between if any point it fails means the whole transaction will be rollback.
I am using TRY & CATCH to handle transaction commit & Rollback . But I am getting below error
Error coming in SQL end is:
Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 1, current count = 0.
Please advise.

Hi,I still haven't got a decent book on relational databases :-)My stored procedure insert_wire inserts values into two tables (wire andcablewire). The wire_ref (primary key) will be the same for both inserts.However, if for any reason the first insert fails then I would like arollback system to take place. I have tried testing for an error (@@error<> 0) after the 1st transaction but I just get a syntax error. Am I goingdown the right lines here? Any tips appreciated.Thanks, Mary.CREATE procedure insert_wire(in wire_ref VARCHAR(22), in standardVARCHAR(16), in a_color VARCHAR(16), in material VARCHAR(22),in metres INTEGER, in amps FLOAT(3), in volts FLOAT(3), in ni SMALLINT, insome_comment VARCHAR(32))BEGINinsert into cablewirevalues(wire_ref, standard, a_color, material, metres, some_comment);insert into wirevalues(wire_ref, amps, volts, ni);commit;END!

Lookup and commit; How it works
I am importing data from text file and I have data lookup to check reference table.
If the reference row doesn't exist I want to add row to reference table, other wise row is added to the detail table.
I am using oledb destination to saving reference table row with rows per batch to 1 and maximum insert commit size to 1.
When I run the package duplicate rows are in grid view. How can duplicates end in there the commit size is 1? Next time the data exists in reference table and should be going to detail not to reference table.

Hello,
I am a SSIS developer from the Netherlands. I have a question about the use of a transaction in a package.
I have a Sequence container with some data flow tasks and some SQL tasks. The TransactionOption for this container is set to Required. The transactionOption for the tasks in the container are set to Supported. After this container I have put some other tasks (like a script task and an send mail task). This last 2 tasks have a TransactionOption set to Not Supported.
I have done this this way because if something goes wrong in the Sequence Container everthing in this container will be rollbacked. This work fine! But if one of the last 2 task goes wrong (the tasks after the container) everthing in the container is also rollbacked. I don't know why this is happening. Can you help me with this?
Thanks! Greetings, Pieter.
