OLEDB Data Source Truncates Pennnies
Mar 11, 2008
I'm importing from a SQL table that has data fields typed as numeric(18,2) and the OLEDB data source component converts the data to integers (as viewed in the data viewer). I've preceeded the column names with (DT_NUMERIC,18,2) with no results. When the data gets saved to a table with the field typed as money, it appends .00. The truncation of pennies (decimal) results in the diminution of the daily results as much as $1,000. How do I pass the pennies through the OLEDB data source component? Is this truncation by default,or is there something I'm missing in the configuration? thanks.

A little background first. I have a header table and a detail table in my staging area/ods. I need to join them together to flatten them out for load. The Detail Table is pretty deep - approx 100 million rows.
If I use the setting (table or view) and set the table name (say, the detail table), the package starts up nicely. But if I switch the OLE DB Source to using a SQL Statement and then join the tables in the SQL, then the Pre-Execute phase of the package takes a VERY long time. I have waited as long as 30 minutes for this phase to complete, but it never finished.
Another twist...If I take the join select statement out of the OLEDB Source and put it in a view on the server, then swith the OLE DB Source to look at the view using the (table or view) mode, then the package gets through the Pre-Execute phase just fine.
Can someone go into detail as to what the Pre-Execute phase does and why a deep table might make it take a long time? I know already that the pre-execute phase caches the lookups, but not much else.
Any help?

Slow OLEDB Source in Data Flow
Hi All,
I have a simple data flow task, composed of only an OLEDB Source, a Conditional Split, and two Execute SQL statements (both insert statements, one after the other). When I run my package in Visual Studio for debugging, I noticed that after executing around ~9800 in the first and another ~9800 records in the second insert statements, the OLEDB Source will take around 3 or 4 minutes to fetch another set of ~9800 records. I have set the DefaultBufferMaxRows property of the Data Flow to 10000. My query to retrieve those 700,000 records runs for about 2-3 mins to finish (which I think should be decent enough). Is this an expected behavior of SSIS? The expected number of records to be retrieved is 700,000, and it takes forever to finish the transfer of these records. Please help

Hi
Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table columns, how would that be implemented? Any help or advice is appreciated.

Hi All,
Another requirement has cropped up with regard to picking up connection settings for data sources from an external File.
My source and target are both in SQL Server. What i need is that if my source or target changes I should just change my external file and same should reflect in my package.
How can I accomplish it? Please suggest some solution.

Hi All,
In one of my SSIS Interface I have to Merge data from a Oledb source and a Flat file source.But after I read from the flat file I have do a basic validation of the file for the length of header,detail and trailer records and then process further.The above Validation I am doing within Script Component.If the validation fails the flow should pass out of the DataFlowTask without Initailsing the Oledb source.
But the problem is i am not able to connect anything to the Oledb source,i.e Oledb source is not taking any incoming Pointers.
Earlier I had done the same Validation in Control Flow Task,but then the interface was reading the same file twice,once in the Control Flow Task and then again in the DataFlowTask.Which i should avoid now.
I hope many of you could have come across such a problem.
Any help on this will be appreciated.
cheers

Hello,
I have 2 table, "table1" is the source one and the other one "table2" is the destination.
Columns in Table1 and in Table2 are nvarchar(max).
Data loaded from table1 is performed by SSIS OLEDB data flow source, I have found out that opening "Data flow Path Editor" in the Metadata, columns are as: DT_WSTR with lenght 4000.
First question:
Why SSIS limit the column to 4000.
Then I get some error for this issue, with the error:
input column "col1" (xxxx) and reference column named (coln) have incompatible data type.
As written before both columns are string, the problem is that SSIS limit the lenght of the string to 4000.
How can I solve this issue?
Thank

Hi,
I'm trying to use query parameters with an Oracle OLEDB Source in a data
flow task and I'm having problems.
I've tried formatting the query each of the following ways...
--
select
frq_code,
frq_name,
update_frq,
uptime_frq
from frequency_bcs
where update_frq > ?
and update_frq <= ?
--
Parameters cannot be extracted from the SQL command. The provider might not
help to parse parameter information from the command. In that case, use the
"SQL command from variable" access mode, in which the entire SQL command is
stored in a variable.
Additional information
---> Provider cannot derive parameter information and SetParameterInfo has
not been called. (Microsoft OLE DB Provider for Oracle).

I am working to archive some old data from a data warehouse using SQL server and SSIS.Β The data will be read and denormalized, then shipped out to a delimited text file.
The rowcount of the incoming data is significant, call it 10M+ rows per unit of work (one text file).
There are development advantages of using a stored proc for the data source - mainly ease of changing the denormalization logic as required.Β Wondering if there are performance advantages of an embeded query for the data source instead?
It was mentioned by one developer that when using a stored procedure, the output stream from the proc and subsequent SSIS steps cannotΒ start until the full procedure processing is complete; i.e. the proc churns out its' result set in one big chunk.Β
He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.

I am try to transfer some tables data from one database server into another database server. I create a package in SSIS, and I use a variable to pass each table name. In Data flow, I use a OLEDB Source, but I cannot set the Data access mode to Table name or view name variable. Ever time, I will get this following error info "===================================

This is a problem that never get solved, sometime I can use other way to avoid it, but havn't found a solution yet, i hope I can get some more idea here.
I am using SQL 2005, when I run
select * into #import1
from OpenRowSet('microsoft.jet.oledb.4.0','Excel 8.0;hdr=yes;database=\ws8webjeff2.xls',
'select * from [jeff2$]')
I get
Cannot initialize the data source object of OLE DB provider "microsoft.jet.oledb.4.0" for linked server "(null)".
when I try to compile a SP with that statement in it, I get the same error, like
create stored procedure test
as begin
select * into #import1
from OpenRowSet('microsoft.jet.oledb.4.0','Excel 8.0;hdr=yes;database=\ws8webjeff2.xls',
'select * from [jeff2$]')
end
so it seems the error may not relate to the real file, since at the compile stage, it should not check the real file?
On my live db, after I restart the SQL service, the statement will work, after a while, one or several days, I get the same error again. I can not restart my live db quite often for sure, so now I have another backup db server, I need run the statement on the backup server and then read the data from there.
I have the same problem at two places, both use SQL 2005.
So far there are three questions
1, why it works after restart, but only last for a while? something about memory? since the backup db seldom need restart and work fine after many days.
2, why it gives error in compile stage?
3, why two dbs in different Enviroment has the same problem
The most answer I have gathered so far is permission issue, true I got similar error if the import file is located in a place which SQL has no right to access. But in this case, it should not be.
Any other idea or suggestion?
thanks

I am using execute sql task to run a stored procedure in oracle database which returns a resultset. This works. Now I need to send the ouput to a destination table in a sql database. Should I use for each loop to pick the resultset and insert it into the destination one by one (which I dont think is a great idea) or is there a better way to accomplish this task (in data flow task) ?
When I use dataflow task instead of execute sql task, the main issue is I am not able to see the output columns when I execute an oracle stored procedure, but when I see the preview I can see the resultset . But I can see the output columns for a sql server stored procedure.

How come no matter what I do SQL server always truncates my dates when they are saved to the database? I save a complete date like 1/1/1900 6:13:42 and no matter what I do it always truncates the seconds off of all my dates, so I always get 1/1/1900 6:13:00. It makes no since because when I save the record the seconds are there, but when I pull it back up they are always gone.

The sql database has an ntext (16) field which contains "information" and is used as a free form turnover log. When I bring this data into an ASP page the "information" gets truncated.
I have tried getchunk, however all formatting on the field is lost.
I have tried putting the field at the end of my query - no change.
I have tried querying the data as a separate sqlrs connection - no change.
I have tried using substring to break it down, the first substring works, however I get errors on the second (Expression result length exceeds the maximum. 8000 max, 12000 found).
I also tried to use substring in sql query anaylzer - and only get the first ~4180 characters.
Is there a way to split this field into multiple nvarchar fields in my temporary table in sql and then concatenate back together in asp report???

An SSIS package to transfer data from a DB instance on SQL Server 2005 to SQL Server 2000 is extremely slow. The package uses an OLEDB Source to OLEDB Destination for data transfer which is basically one table from sql server 2005 to sql server 2000. The job takes 5 minutes to transfer about 400 rows at night when there is very little activity on the server. During the day the job almost always times out.
On SQL Server 200 instances the job ran in minutes in the old 2000 package.
Is there an alternative to this. Tranfer Objects task does not work as there is apparently a defect according to Microsoft. Please let me know if there is any other option other than using a Execute 2000 package task or using an ActiveX Script to read records from one source and to insert them into the destination source, which I am not certain how long it might take and how viable will that be?
Any inputs will be much appreciated.
Thanks,
MShah

I created a stored procedure based custom conflict resolver in SQL 2005, I return the winning result set and also save that result set to a test table to compare the values. The values saved to the test table are correct but some of the values saved as the conflict winter are truncated.
Example a char(3) filed is updated at the subscriber as 111 and updated at the publisher as 222, in my custom conflict resolver if I use the value from the subscriber the conflict resolver updates the field as 11 , if I use the publisher value the conflict resolver updates the field as 22 . Now the same records is saved to the test table correctly as either 111 or 222 depending on the logic I used. So the result set has the correct values, its after the custom conflict resolver is called where the values is somehow truncated. Has anybody run into this before and what steps can I take to avoid this.
Thank you,

I was having one package which uses a source query in OLEDB Source Control and fetches the record and a couple of lookups and then an oledb command to insert/update the records in the table using as SP. I changed the source query(Infact the package) and removed in lookup and a different SP was called similar to the old one. But my problem is the package which was before taking only minutes to update 50,000 records is now taking more than 2 hrs. The problem is the number of records it is fetching from the source each time is very less.. its fetching hardly 500 records a time compared to nearly 2500 records before. Where am i going wrong? Any suggestion greatly appreciated.

Hi,
I am running an MDX query in SSIS but I don't know what is the best way of doing this, performance wise.
I know I can run the MDX query through an openquery in the OLEDB, and also run it through a Datareader, no openquery needed.
I know the datareader is slower in a normal basis due to .Net, but in this case the OLEDB is running an open query to a linked server which won't be fast like running a regular SQL.
If anyone knows which of this two run faster in this scenario I'll appretiate if you let me know.

Hi,
Firtsly - I am new to SSIS if my approach could be improved then I welcome suggestions.
Scenario: I have a large SSIS package that consolidates / summarizes work week information from several data sources. Currently each data flow task in the control flow calculates the from and to date that is filtered on, for example:
DECLARE @FromDT AS DATETIME
SET @FromDT = CAST(FLOOR( CAST( DATEADD(D, -7, GETDATE()) AS FLOAT ) ) AS DATETIME)
DECLARE @ToDT AS DATETIME
SET @ToDT = CAST(FLOOR( CAST( GETDATE() AS FLOAT ) ) AS DATETIME)
I would like to remove these statements that appear in most steps and replace them with a global variable that is used throughout the package. This statement would only appear once & it would make the package much easier to run after failure etc.
Problem: I am using Data Reader Source with the 'SQLCommand' property specified. It looks like parameters are only supported if an OleDB connection is used?
So I switched to an OleDB connection and no parameters are recognised in the string - a forum search reveals that parameters in sub queries are not always found properly. The solution to this problem appears to be, to set 'Bypass Prepare' to True but this is a property for the Execute SQL task, not the Data Flow Task source.
Questions:
Does the Data Reader Source control from Data Flow Source toolbox section support parameters?
Can anyone suggest a fix to the OleDB Source issue with Parameters?
Is there a better way to solve my problem e.g. Using Execute SQL Task instead of Data Flow tasks etc
Example SQL:
This SQL is an example of the SQL for the OleDB Data Source (within a Data Flow task)
------------------------------
--RADIUS LOGINS
------------------------------
DECLARE @FromDT AS DATETIME
SET @FromDT = CAST(FLOOR( CAST( DATEADD(D, -7, GETDATE()) AS FLOAT ) ) AS DATETIME)
DECLARE @ToDT AS DATETIME
SET @ToDT = CAST(FLOOR( CAST( GETDATE() AS FLOAT ) ) AS DATETIME)
DECLARE @Attempts AS BIGINT
SET @Attempts =
(SELECT COUNT(*)
FROM dbo.Radius_Login_Records
WHERE LoggedAt BETWEEN @FromDT AND @ToDT)
DECLARE @Failures AS BIGINT
SET @Failures =
(SELECT COUNT(*)
FROM dbo.Radius_Login_Records
WHERE LoggedAt BETWEEN @FromDT AND @ToDT
AND Authen_Failure_Code IS NOT NULL)
DECLARE @Successes AS BIGINT
SET @Successes = @Attempts - @Failures
DECLARE @OcaV1Hits AS BIGINT
SET @OcaV1Hits = (SELECT COUNT(DISTINCT LoginName)
FROM dbo.Radius_Login_Records
WHERE LoggedAt BETWEEN
@FromDT AND @ToDT
AND EAPTypeID = 25)
DECLARE @OcaV2Hits AS BIGINT
SET @OcaV2Hits = (SELECT COUNT(DISTINCT LoginName) AS OcaV2Hits
FROM dbo.Radius_Login_Records
WHERE LoggedAt BETWEEN
@FromDT AND @ToDT
AND EAPTypeID = 13)
SELECT
@Attempts AS ConnectionAttempts,
@Failures AS ConnectionFailures,
(CAST(@Successes AS DECIMAL(38,2)) / CAST(@Attempts AS FLOAT) * 100) AS SuccessRate,
@OcaV1Hits AS OcaV1Hits,
@OcaV2Hits AS OcaV2Hits
Please remember, I'm new to SSIS - so be detailed in your response. Thanks for your help!

I am debugging a Data Flow task in my SSIS package. When I run the package in debug mode, one of the OLEDB Data Sources turns red. I have rerouted all Error Output to a flat file, and put a Data Viewer on that path: no rows get sent. When I click the Preview button on this component in Design mode, I see the expected data and get no error messages. The connection does a simple table access...no SQL command. I don't see anything different between this component and other OLEDB sources in the same package that don't trigger any errors. I've tried dropping and re-creating the component with the same results.
What else can I do to debug this?

Guys,
I am having a nightmarish time getting an Oracle Connection Manager working as a source in my SSIS package.
The CM is called "OLTP_SOURCE". When I inspect the configuration and test connection, it succeeds, however when I go to run the package (both in debug mode and via DTEXECUI) I get the following error:
The AcquireConnection method call to the connection manager "OLTP_SOURCE" failed with error code 0xC0202009
After this happens, if I go into an OLE DB Source within a DFT, I get the following:
No disconnected record set is available for the specified SQL statement.
Now, if I go back into the CM, enter the password and test, it succeeds. From this point, I will go to preview the data in the OLE DB Source, and it comes back fine. However, when I go to run the package, I get the same error time and time again:
The AcquireConnection method call to the connection manager "OLTP_SOURCE" failed with error code 0xC0202009
The quick reader will suggest that the password is not being persisted. To this end, I have tried each of the following techniques to no avail:
1. Double, Triple and Quadruple check that the "save" password option in the CM is checked.
2. Hardcode the connection string in the dtsx XML-behind.
3. Enable Package Configurations and hardcode the connection string in the dstsconfig file.
4. Run the dtsx file using DTEXECUI, providing it with the configuration (that includes the hard-coded password).
5. Run the dtsx file using DTEXECUI, providing it the connection string in the Connection Managager override UI.
Can anyone help shed some light on what might be going on? So far, it is obvious that there has to be something that I am doing wrong because (syntax dialect differences aside) I can't imagine that Oracle sources should be this much of a headache.
Thanks,
Rick

Hello All,
I understand that the parser is having issues parsing my second command but I was wonder if anyone had stumbled on a work around for this:
-- OLEDB Source has no problem with this:
SELECT *
FROM some_table
where
last_update_dt = ?
-- OLEDB Source errors on this:
SELECT *
FROM some_table
where
Convert( char(12), last_update_dt, 112 ) = Convert( char(12), Cast( ? as DateTime), 112 )
The first SQL statement won't return the desired rows because of the wonderful time stamp, the second works well but the provider won't parse it. I have used the "SQL command from variable" to work around this but we have some tables with 200+ columns, so the only way to use the "SQL command from variable" is to do a select *, which I'm trying to avoid, for both performance reasons and company standards.
Any thoughts?
Thanks,
Raymond

Hi All,
Is it possible that an OLEDB Data Flow Source is imposing locks on the source tables? The source is an SQL Server OLTP environment, and although the package will be scheduled to run nightly when the application sees little to no use, I want to be sure that the process isn't impacting any application functions.
Thanks for the advice!
