Integration Services :: Oracle Sequence Number Within SSIS
Jul 22, 2015
For each row coming out of my data source, I would like to add the result of an Oracle query to it (select sequence.nextval from dual).
I need to acquire the sequence number before all my processes in my data flow, so I don't want to have a trigger in Oracle call nextval and do it automatically for me.
I also think getting the value of nextval inside of a variable at the beginning of the process would not work because it only increments the value once.
I've been working on an SSIS package trying to load some data and the archive sequence is faulty. I've been trying to load a few tables created in a previous sequence into a local archive file and I've been getting the error "Could not find a part of the path."
The results aren't telling me what it's finding last and so I don't know where to start.
And the source DOES have data in it. It's something between the source and the destination.
I've made connections in SSIS to Oracle before by setting up TNS but this latest connection is different.
I've been give an SSL cert that I had to import into the Oracle Wallet Manager and to get connected in 'Oracle SQL Developer' I had to choose connectionType = advanced and drop the following line in the JDBC URL section
I am trying to pull data from an Oracle Db using SSIS. If I use the Table/View option in the Access Mode option on the OLE DB Source component, it works fine. But when I use the SQL Command option, the processing get stuck at Pre-Execution stage.... (for days).
I'm having an issue connecting to an Oracle database using Visual Studio 2013 - Business Intelligence tools.I am running Windows 7 (64-bit), Visual Studio 2013, and have SQL 2012 Enterprise (64-bit) on my local machine. I downloaded the MS Connectors v2.0 for Oracle found here. But when I try to add a new connection either through the connection manager or inserting a Data Flow Task and looking for the Oracle connections in the "Other Sources" or "Other Destinations" - neither option is available.I have the 32-bit Oracle client installed, the tnsnames.ora file has been created and I can connect to the Oracle DB through PL/SQL.I see Microsoft Connector for Oracle by Attunity 2.0 in my Programs list - installed for this file: Attunity SSISOra Adapters SetupX64.msi. don't know what else to try to get the connections available.
In SSIS, I created a flow and within that flow i need to create an automatic number generator. The flow is simple: Ole db source part, a multicast part and a flat file destination and a ole db destination. In the Ole db source there is no field that is the starting point for this generator. This automatic nr should start with 10000 and each time a row is found it should be increased by 1.
First question: is it possible to create a column in SSIS flow which is the starting point for the generator (in this case 10000) or should it be created in the source table?
Second question: where in SSIS and with what component can i create such a generator??
I'm executing Oracle procedure, which has three OUTPUT parameters and returns results in table type variable. i should not use ODBC, MSDAORA providers to call the procedure. So I'm planning to using Oracle OLEDB provider. I'm able to execute the procedure successfully, but when i do check (while dr.Read()) its not returning any records. But I know as per stored procedure results, it should return 66 records.
Dim conn As New OleDbConnection Dim cmd As New OleDbCommand Dim dr As OleDbDataReader Dim QSQL As String
I've got this issue with a query in SSIS. From a table in SQL Server I'm getting over 25000 different identifiers. These identifier are associated to many values in a table in one Oracle Database. This is the schema that I have implemented for doing this.
The problem is that some days the identifiers can be over 45000, and at this point perform a loop for every one is not the best solution (It can take to much time to get the result). Previously I have performed another query where from the SQL statement.
I am creating and sending a unique row with all the values concatenated and then I have recover this unique string from an object and use it to create the query in the ODBC Source that invoke the table in Oracle: something like this: 'Select * from Oracle_table' + @string_values
with @string_values = 'where value in (........)'. It works good because the number of values is small enough to be used, like 250. But in this case I can not use this approach because the number is really big and obviously the DBA of Oracle is going to cancel the query.
So I wonder, how can I iterate over the object getting only a few number of values everytime, something like 300 or maximum 500, to avoid the cancellation of the query but at the same time doing the minimum number of loops.
I have a stored proc that is returning the results I need for output to .txt file.
Is there a way in SSIS to commit 50K (or whatever number) row batches at a time or should I just handle this in the stored proc?
select * into #TempTable from SomeTable [WHILE LOOP] --throttle commit batches of 50K rowcount select * from #TempTable [END LOOP] drop table #TempTable
But If I'm doing this in SSIS, I can't drop the #temp table otherwise I have nothing to output right?
I'm using Script Component to load data into Oracle DB due to the poor performance issue. Now, I found it will missing some data during the transmission. Please see the screenshot below:
I have (6) sequence containers, each with a data flow task and script task. The script task renames the file and the data flow uses an OLE DB Source connection to export to a flat file using the Flat File Destination connection.For sI have been unable to move from the 1st sequence container to the 2nd (and the next and so on...). I am trying to do this "on success" (on failure I generate an email notification within each container), but am apparently missing a piece to this because after the sequence container executes, which it does successfully, nothing happens.
We have Sequence generator (Next Value) enabled for surrogate keys (SQL Server 2012). When we use the new SCD task, we get the following error:
[Insert Destination [42]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.An OLE DB record is available. Source: "Microsoft SQL Server Native Client 11.0" Hresult: 0x80004005 Description: "NEXT VALUE FOR function cannot be used if ROWCOUNT option has been set, or the query contains TOP or OFFSET. ".
Is there any know issue that these two features [SCD task and Next Value] cannot be used together?
I am working on 1 POC project.I have 2 customer having source file in txt format, but the column sequence of both customer are diffrent.Number of columns in all files are like below.
CustA
ID NAME AGE 1 VIPIN 29
CustB
ID AGE NAME 2 29 jayesh
As per source file you can see that CustA have column sequence ID,NAME,AGE and CustB Have ID,AGE,NAME sequence .I have target table #Temp with ID,NAME,AGE sequence.Like that I have many files from both customer, I have to load in ID,NAME,AGE sequence from all source file to target table.How can we change the sequence of source column before loading to target table.
I have a sequence container in my Package and this sequence has more than one control flow tasks.
Can I create the checkpoints such that only the failed component inside the sequence container runs again and not the other successful components/tasks in the sequence container?
An Execute SQL task returns one row with two values that are correctly stored into variables.
Based off those two variables, a sequence container is chosen to execute.
That sequence container then does magic. The last step of the container has an execute SQL task that runs and stores the result in a variable - let's call this[User::result] with type Int32.
Based off the value in [User::result] one of two final tasks run. A non zero value executes one task; a zero value executes another. Basically,SOMETHING runs after this.
Simple? I thought so... except Step 4 doesn't work. If I set a post-execute breakpoint on the sequence container, the variables are populated as expected, but nothing else runs. If I add another task to run (without a conditional expression) to run after the sequence container completes, the pre-execute breakpoint shows the data looking exactly as I expect.
Those script tasks are just MessageBox.Show calls and the expression, as you can see, doesn't use variables at all.
I have multiple sequence containers in my package. I only want to have one sendmail task for the failure/completion of the package. If I put the sendmail task in the last sequence container and the first seqence fails, the sendmail task will not be reached and therefore, no email will be sent out.Is there a way to have one sendmail task for all the sequence containers and allow it to send mail regardless of what sequence fails/completes?
I have a sequence container with 2 task into. If one of the tasks alert a failure then the sequence container should alert a failure too, but it doesn't. For testing I forced the error with setting the attribute ForceExecutionResult to Failure for one of the tasks. The task fails, but the sequence container succeeds.
I tried:
- changed the Precedence Constraints from AND to OR between the 2 tasks into the sequence container - changed the attribute FailPackageOnFailure setting True - changed the attribute FailParentOnFailure setting True
i was used the Follwing DataFlow for my Package.using Oracle 8i
FalteFile Source -------------> Data Conversion --------------->OLEDB Destination (Oracle Data table)
using above control flow to map the Source file to Destination . When i run the SSIS Package teh Folwing Error i got
"Truncation Occur maydue to inserting data from data flow column "columnName " with a length of 50 "
regarding this Error i i understood its for happening Data Length . so that i was changed the Source Column Length Exactly Match with the The Destination table.
still i am getting this Error. pls any one give me a solution . SHould i Change the DataType also?
I've been searching for a solution for this for a week-ish, so I thought I would post my quesiton directly. Here is my scenario..
Source: MS SQL Server
Destination: Oracle 10g
The destination table has a partition set on a column called "DATE_HIGH". How do I populate this date high column in my package? Currently I just have a source object, and a destination object, but I'm unclear how to populate this field in the destination. I've read one blog that states "use OLE DB Command" - but that isn't enough information for me to implement - Can someone be more specific in these steps? Here is an example of what my newb-ness needs to understand
OLE DB Source (Select * from Table) ---> OLE DB Command (What query goes here?) --> OLE DB Destination.
Second part of my question: There is a second column called "ROW_NUM" and there is an Oracle Sequence provided to me... What objects do I need (Source, Destination, OLE DB Command etc...) and how do I call this sequence to populate on the fly as I'm loading data from my source?
If these are simple questions - my appologies, I am new to the product.
I'm using - Destination - Oracle driver - oraOLEDB.Oracle.1 (native ole dboracle provider for ole db)
Source - SQL driver - microsoft ole db prover for sql server. I want to import data from sql server to oracle. Challenge is, I have 1 million records on oracle. I have 100 records on sql server (these 100 records count will change daily). So, I thought of using 'lookup' task looking taking record from ms sql and fetch corresponding record from oracle. But when I use lookup, all records from oracle are loading into cache, which is taking approx 3 hrs.
Oracle linked server. If I query Oracle in my packages using SQL it tooks age if I use an OLE DB Oracle connection it takes minutes, so I started to develop my packages using the OLE DB Oracle. The point is that in order to connect the Oracle db I must set up a password (Oracle requires a password but if I use directly SQL it doesn't need any password). This password changes every month so I do need to set up the password for...if I can come up with another solution? I don't know, maybe a unique connection...just set up the password only once.
In previous versions of BIDS we were able to customize the DataFlow toolbox to incorporate the Oracle Source and Oracle Destination items - however, it appears this is no longer the case in SSDT (no option to customize toolbox). I've installed the 3.0 Microsoft Connectors for Oracle - when I create a new connection in the Connection Manager I can see the Attunity drivers, but under Other Source/Other Destinations in the Toolbox I cannot find the Oracle Source/Destination components.
I am having an issue while transferring some tables from sql server database to oracle schema. The table has over 150 million records. I have created a view referencing that table and am transferring the view. I am using "Oracle Destination" data flow destination using Microsoft Connector for Oracle by Attunity with SQL Server 2008 Integration Services. I am repeatedly getting the following error:OCI error encountered. ORA-12571: TNS:packet writer failure The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020.
I would like to export all tables from Oracle 11.2 to MS SQL Server 2012 R1.
Using the tool "Microsoft SQL Server Migration Assistant v6.0 for Oracle" did not work for me because there are too many warnings and errors regarding the schema creation (MS cannot know it because they are not the schema designer). My idea is to leave/skip the schema creation to the application designer/supplier and instead concentrate on the Oracle data export and MS SQL data import.
What is the easiest way to export all tables data from Oracle to MS SQL Server quickly?
Is it:
- the „MS SQL Import and Export Data“ Tool - the “MS SQL Integration Services” Tool - not Oracle dump *.dmp format because it is a propritery binary format - flat file *.csv (delimited format)
Getting following error while trying to connect to ORACEL database using OLEDB manager.
Error at RADAR [Connection manager "RADAR_Updated"]: SSIS Error Code DTS_E_OLEDB_NOPROVIDER_ERROR. The requested OLE DB provider OraOLEDB.Oracle.1 is not registered. Error code: 0x00000000. An OLE DB record is available. Source: "Microsoft OLE DB Service Components" Hresult: 0x80040154 Description: "Class not registered".
I am transferring data from Oracle tables into text files, and facing these errors.
1. I have a varaible working as an expression and my query goes into that variable and onwards that variable is passed to dataflow task, which parse the query. my query is simple saying "Select * from PLS.ABC" where PLS is my schema, but the task generates error "Opening a rowset for "Select * from PLS.ABC" failed. check that the table exists in the database. and surely the table is there.
2. I have a foreach loop that iterates through all the table names and the table names are passed onwards to the varaible query, the dataflow task inside the foreach loop gets the variable query and will generate text files based on tablenames which i have supplied in another variable to the connectionstring property of the flatfile destination. Is it possible or not. all the tables have different columns and i need the output in text files.
Looking for sample ETL package to extract data from SQL Sever Database and load into Oracle Database using SQL SERVER INTEGRATION SERVICES 2008. The requirement is for full load and incremental load both.
