Source And Destination Table Equality
Feb 20, 2006
I have searched the SSIS forum for an answer to my question, and I think I have found my answer but what i have read does not come out directly and answer my question.
I am attempting to create an SSIS package that imports data from a Visual Foxpro table into a SQL Server table. From what I have read, the source and destination tables must match column for column. Is this correct? My SQL Server table has a few more columns in it. However, i consistently get "Cannot create connector. The destination component does not have any available inputs...blah".
From what i have read, it sound like the reasoning is that my source and destination tables do not match.
Is this correct, or am i barking up the wrong tree?
Thanks in advance...

I am stuck on finding a solution to transpose source data from a system via a metadata look-up table into a destination table. I need a method to transpose/pivot the source data into columns (which are by various data-types). The datatypes for each column are listed in a metadata table.
Source Data Table:
Table Name: Source
SrcID AGE City Date
01 32 London 01-01-2013
02 35 Lagos 02-01-2013
03 36 NY 03-01-2013
Metadata Table:
Table Name:Metadata
MetaID Column_Name Column_type
11 AGE col_integer
22 City col_character
33 Date col_date
Destination table:
The source data to be loaded into the destination table(as shown below):
Table Name: Destination
SrcID MetaID col_int col_char col_date
01 11 32 - -
01 22 - London -
01 33 - - 01-01-2013
02 11 35 - -
02 22 - Lagos -
02 33 - - 02-01-2013
03 11 36 - -
03 22 - NY -
03 33 - - 03-01-2013

I want to process data from source table to destination table without using cursor.
At this point; we are creating temp table and inserting data from source to temp table. once we get data into temp table; using while loop we are processing record one by one to destination table.
while executing stored procedure; we noticed that there are few records in source table which are invalid and stored procedure is terminating from such records.
Any better approach to log INVALID data and resume code to process next record instead of terminating.

I have a requirement to take xml file, in case the number of column changes, it should not fail the package, rather it should load the data in destination table. Destination table could be altered separately depending on xml schema by the DB team in production.

Hi,
I am having a Data flow task in For each loop which will gets 100 sourcetable names and 100 target table names...
am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination.
I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.
The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....
is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)
Thanks

Hi,
When expoting data from excel to sql server table, using SSIS package, after exporting is done, how would i check source rows are equal to destination rows. If not to throw an error message.
How can we handle transactions in SSIS
1. when some error/something happens during export and the # of rows are not exported fully to destination, how to rollback the transaction in SSIS.
Any sort of help would be highly appreciated.

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,

I am having a hard time having restrictive matches on an equality select where nchar is involved.
The table is:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Download_Hash_Log](
[log_id] [int] IDENTITY(1,1) NOT NULL,
[hash_value] [nchar](16) COLLATE Latin1_General_BIN NOT NULL,
[log_date] [smalldatetime] NOT NULL,
CONSTRAINT [PK_Download_Hash_Log] PRIMARY KEY CLUSTERED
(
[log_id] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
There is exactly one row in the table. It has value 1234567890123456 for hash_value column.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'1234567890123456')
returns the row - Good.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'12345678901234')
doesn't return the row. Good.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'123456789012345')
returns the row. WRONG.
SELECT *
FROM Download_Hash_Log
where convert(varbinary,hash_value) = convert(varbinary,N'1234567890123455')
returns the row. WRONG.
Please help me explain why the last 2 conditions are failing. Why is SQL doing a fuzzy match and returning the row even though it is literally different from the stored value? Is it ignoring the last byte?

Hi,
My OLE DB Source and Excel desintation values all will be assigned during the run time but it does work during design time but as on runtime columns are different. That's why it does not work.
Here is what I want to accomplish, I have table which contains all my report which needs to dumped to excel at the month end.
SQL Task using ADO enumrator read one record(one report), Give that record to For Each contair which Create the Excel file on the fly using one of variable from my table and uses a stored procedure to dump data to excel using Dataflow Task.
xlsQuery

Hi,
I am building SSIS for 3 different files that have identical
schema and mapping logic.
In my OLE DB Source (object name - "OLEDBSource_SourceTable")
Data Access mode is "Variable name".
As soon as I swithced to this Data Acces mode
it started to give me an error:

Hi
I am new to SSIS. Probaly What I am asking is the simple one. But I dont know. I have a requirement. My Data source is Excel file and Destination is SQL Server . Excel file consist around 10k unnormalized rows which should be loaded to the multiple normalized master and child tables into the destination with the Primary key (identity column) and foreign key constrains. Even sometimes package should check for destination database table for matching Source column (Excel) code with the lookup table code (destination lookup table) and get the Primary key of Lookup table and put it into the destination table. Please help me the way to find the solution for this

Hello,
What I'm trying to accomplish is to have a variable names "SourceTable" and "DestinationTable". So for each SourceTable, the DestinationTable will have the same columns. All I need is to auto-map these columns between source and destination via code?
Is this possible?
Thanks,

Given the following scenario, what kind of performance should be expected in transferring about half a million rows? We are seeing about a 9 minute execution time. Is this reasonable for about 460,000 records moving from source to target, with 3 inner joins from the source?
Source: Server A.OLTPDB
Target: ServerA.DataMartDB
Server A is running SQL Server 2000. SSIS is running on a different machine, Server B.
The reason for this is that we are distributing the SSIS package for use with a BI product built on SSAS 2005 and the requirements are such that the client could very well have the source OLTP database on a different physical machine than the data mart.
My understanding is therefore that:
1. SSIS will do all of the heavy lifting on Server B.
2. Even though OLTPDB and DataMartDB are on the same server, it is expensive for Server B to pull the records from Server A and then send them back to Server B, but with SSIS being on a different machine, this is inevitable.
3. In the OLE DB Source Adapter, specifying table or view has the effect of an OPEN QUERY command, whereas a SQL command with straight SQL will be executed on Server B and the former would be somewhat more performant.
Can you guys validate/dispel these assumptions?
TIA,
Rick

All,
I am having a brain-fart or something. I need help!!!
I'm developing a transform that selects data from a SQL script, then transforms that data, and then needs to update the data back into the same source table. The transform is working great, but I can't figure out the update table part. I've got it adding the transformed records to the table, but that's not what I need to do. I need to update the table with the changed data.
Any sample code or blog links would be greatly appreciated!
Thanks for the help!

Hi,
I have read only permission in the source (OLTP) database. The source database is running in SQL Server 2000 and the size is more than 200 GB. I need to pull data from source and load target which is running in SQL server 2005.
Following are the objectives I want to achieve.
Data should be loaded on incremental basis.
Whatever changes take place (Update/Delete) in source, that should be replicated to already uploaded data.
Here I want to mention that, the source database does not have any identification key or timestamp column like Updated_Date by which I can filter the data which are recently inserted or updated into the source and upload the same. The source does not maintain any history data also. So I do not have any track of deleted record also.
I don€™t have any scope to change the schema in the source. In this scenario can anybody suggest me the best approach to achieve the above mentioned objectives?
Can I retrieve only the recent updated or inserted date form transaction log back up. Can log shipping solve the give the solution?
One more question. Say I have a table and I am exporting/importing all the data from/to my target table using SSIS or DTS. In this scenario does using query or using directly the table affects the performance?

I need to write TSQL script that will insert, update, delete rows in a production db from new, updated and deleted data from staging db. They are both in different servers and I can only use TSQL. Basically, the production DB needs to be synchornized with the staging DB.
I was thinking using dynamic sql, cursors, and linked servers. Any ideas?

Hello Everyone,
Please do inform me, how can I check if there is a new record or changed record from the source.
NOTE: my source is Flat File and destination is Oracle Table.
What is needed from my side is the history load (Type 2).
This is not possible thru SCD component in Integration Services, If my source is Oracle (Even after I had added the parameters in my OLE DB)
Please do inform me about this process. Very important.
Thank you

Hi,
I am new to SSIS can u help me out in this i have a source(Flat File) and target SQL Server 2005. Source has got 2 columns- Col1 and Col2 even target has got 2 col's Col1 being the PK. I have created a package that checks if target and if the record exist it updates and if it does not it inserts. My package looks like
Source - lookup on target- Conditional split- Derived Column and then 2 OLE DB Destinations 1 for inserts and 1 for updates.
I have created a relationship in lookup with col1 from source and col1 from target and col2 as lookup col and connected red output to 1 OLE DB for inserts and redirect rows to it. Green out put i have taken to conditional split and gave condition like Col2 from source is not equal to lookup col2. I run the package with this it is inserting new records but not updating it.
I tried to add derived column after conditional split but lacks in writing expression that says update col2 records if they changed at source. Can u help me out in this scenario. I would appreciate if you could get back to me ASAP.
Thanks

I am a complete newbie to SSIS. I can create a simple package to transfer data between SQL instances and thats about it.
I have tableA (source data) and tableB (Destination data). TableA has 4 column and tableB has 5. I want to transfer all of the columns from tableA into TableB, but the 5th column in tableB needs to be populated with the ServerInstance name of the server TableA sits on. Do I need to have multiple data sources to achieve this? I have tried but no matter how I set it up, the Column in the destination is set to ignore.

Hello,
My company is moving to a SQL Server-based packaged application early next year. We€™re planning our SQL Server architecture but have some questions that I can€™t readily find answers for. I€™m hoping someone here can point me in the right direction.
We have three servers, I€™ll call them A, B, and C. We want to duplicate all changes to certain databases on server A to server B, then duplicate changes to selected databases and tables on server B to server C.
Ideally we€™d run SQL Server 2005 Enterprise Edition on all three servers, but the packaged application vendor does not support SQL Server 2005 yet, only SQL Server 2000. Our license agreement with them does not allow us to use replication on server A. We€™re free to do whatever we want on our other SQL Servers, but server A must sit alone, untouched, like a monolith on a far-away moon. (I€™m lobbying to have the server named Tycho, or TMA2.) Stranger still, they€™re OK with log shipping from server A to other servers. We€™ve tried to explain that replication and log shipping are both core function built into SQL Server, and that if one is acceptable, then both should be. Their fear is that replication could cause performance and stability problems, and to eliminate this possibility they€™re ruling out replication on server A.
Given these constraints we€™re resigned to using SQL Server 2000 Enterprise Edition on servers A and B, and SQL Server 2005 Enterprise Edition on server C. We plan on periodically shipping logs from server A to server B and applying them at server B.
We€™d like to know if it is possible to also use transactional replication on server B to duplicate changes from server B to server C. I€™ve used log shipping and replication in the past, but never at the same time. My understanding is that a database goes into recovery mode while a transaction log is being applied and that any user changes to the database after the log has been applied will cause later log applications to fail. The scripts I€™ve seen that are used to apply the transaction logs put the database into single user mode after the log has been applied to prevent this.
This raises a few questions:
If we try to RESTORE a log to a database being used as a source for transactional replication articles, will the RESTORE fail? Or will the RESTORE start and break the transactional replication? I€™ll test this on my own, but it€™d be nice to know if anyone has already experienced this.
Is it possible for us to have a database in read-only mode serve as the source for transactional replication articles? (I can€™t imagine why not, ever though it seems counter-intuitive - why would you want to replicate transactions from a database that has no transactions?)
If the answer to number two is yes, can we suspend transactional replication on a database, RESTORE a log to the database, put the database into read-only mode after the RESTORE, and restart the replication on the database?
Thanks in advance for sharing your wisdom, everyone!

If mTask.Properties.Item(x).Name = "SourceConnectionID" Then
CnID = mTask.Properties.Item(x).Value
Exit For
End If
Next
For x As Integer = 1 To mPkg.DTSPackage.Connections.Count
If mPkg.DTSPackage.Connections.Item(x).ID = CnID Then
Return mPkg.DTSPackage.Connections.Item(x).Name
End If
Next
Return mTask.Properties.Item("SourceObjectName").Value
How can I retrieve or Set "SourceConnectinId", "SourceObjectName" of a data flow task in SSIS
Please help me to solve this problem.

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.

I am bring a date from a OLE DB Source (SQL Command) as [select cast(convert(varchar,getdate(),101) as varchar(10))] to a Flat File Destination (CSV File). The data in the source is show as "1/1/2007", which is how I need it to display in the file. The flat file defaults to showing the data as "1/1/2007 00:00:00." I did change the destination field to a String, and still, I geting the timestamp. I tried using a data conversion transformation, and I am getting bargage data when converting the date to a string.
Can any one give me insight on how to populate a date into a comma delimeted file as "1/1/2007", not "1/1/2007 00:00:00."
Thanks in advanced.
