Short Question: How do I delete all records from a destination table prior to appending new data to that table?
I am working with a SQL database that was migrated from MS Access. All relationships, primary keys, and identity columns have been set identically to the MS Access database values. The MS Access database is still being used as the database of record until the SQL database is fully functional with front-end, etc.
I want to delete the information stored in all the SQL tables, and then append the MS Access values to the SQL tables. I was able to write delete and append queries in MS Access to correctly transfer data to the SQL tables. However, I would prefer doing this through SSIS because I have several other sources of data to move to a SQL Server database and most of those other sources are not a MS Access database.
Due to relational entegrity settings, I need to delete the records from 8 tables in a specific order. I have tried independent control objects for each of the 8 tables with data flow objects of either "OLE DB Command" or "OLE DB Source" with the SQL command as "Delete From TableName". Results of the debug indicate everything is "green" but no records were deleted fromt the tables.
Hi all,
I am developing an ETL wherein the requirement is to do an incremental load and at the same time, if there is a record that got deleted in the Source delete it from the destination too, makes sense.
The approach am doing is, pick data from the SRC and Destination, pass it onto a Merge join component, do a Full Outer join, then pass the rows to a conditional split. Newly Added records and updated records I can handle, how do I handle the Deleted records?
Am I correct in the way I am doing or there is something better to handle this?
Thanks in advance
I'm a novice to SSIS (and we've never used DTS).
Writing a Control flow that inserts records worked fine, using lookups and all, but i can't find somewhere an example on how to update records of even delete records.
Any suggestions ....
Thx

Hello friends,
I have the following (simplified):
1. Flat File Source
2. Conditional Split, Case Good = !ISNULL(KEY) Case Error = ISNULL(KEY)
3. Case Good -> Writes to Good Flat File (with timestamp in the title)
4. Case Error -> Writes to Error Flat File (with timestamp in the title)
Most job runs have no errors but the error file is created as a zero byte file anyway. If there are no error records I don't want the error file created. How might I accomplish this?
Thanks
Hello everybody
I have one question about deleting blank row on flat file destination from conditional split.
I create an SSIS package to filter data from Flat file source.
On flat file source, it is Ragged right format and header row delimeter in {CR}{LF}
the coulums are devided manulaay using markers.
I use only 2 columns divided and send the source into conditional split task and the conditions are given to filter data,
when the output from conditional split is placed on flat file destination, i notice blank rows on the output. I want to delete the blank rows so the result data can be displayed continuously in rows.
anybody has any idea for this? I know the script task will work but hope to avoid to use script task.
Thank you in advance for all the help.
Hi
I am trying to use a conditional split task so that I can check for specific fields. If the value doesn't exist I am piping the records to a derived field task, where I add an error. I then try to send these records to a flat file destination so that I can keep track of them. However, when I execute the SSIS data flow task I get the following error
[Log Invalid Records [5496]] Warning: The process cannot access the file because it is being used by another process.
This file isn't being used by any other process as far as I can tell, and the only process using it is the SSIS task trying to write to it.
If anyone has any ideas, then I would really really appreciate it
Thanks

Hi,
Here is my problem :
I work on a SSIS package with SQL SERVER 2005
I need to extract data from a table and put these data in csv files
But... the flat files name should be dynamic and assigned by a variable ...
Here's an example of my table :
Column header :
Id, Name, Number
1 TOM 22
2 TOTO 44
3 SAM 44
4 RADIO 55
I expect to have 3 csv files :
USER_22.csv
USER_44.csv
USER_55.csv
for example : USER_44.csv contains :
2;TOTO;44
3;SAM;44
if there's 50 different number, i expect 50 files
can i do that in a dataflow ?
thanks for answering
Good Afternoon,
So this one has been bugging me for a while and I am ready to punt...
Is it possible to dynamically create a text file destination in SSIS and then pump the results of a query stored in a variable to this text file?
So my package looks like this
1) SQL task that pulls back a list of tables to be exported
2) For Each Loop ADO enum that passes the table name to a SQL Task that builds the select...ie select * from <DTS.Variables()>
3) Data flow task that sets the command from variable from step 2
4) Text File destinaiton that is built using a varable as the connectionstring
I am delaying validation in steps3 and 4 above without any luck...basically I am curious if i can even do what I am thinking I should be able to do here...I get as far as getting metadata errors because SSIS can't seem to handle dynamically filling the pipeline with the columns from the variable/SQL statement.
Am I missing something? Is this possible?!
Thanks in advance.

I'm looking at SSIS and SqlBulkCopy as a possible method to quickly insert and process large amounts of data, my current method uses the sp_xml_preparedocument and OPENXML to parse an xml document of the data I want to process and insert into the database, however I'm noticing the performance of SqlServer parsing the xml document isn't that good.
I found the C# SqlBulkCopy method (new in .NET 2.0) and I was thinking it would be faster to use that to load my data into a staging table and then use SSIS to extract the data from the staging table, process and transform it as necessary and finally load it into the final destination tables. I was able to create an Integration Services Project that selects the data from the staging table, does a bit of processing on one of the fields (by calling a stored procedure), and finally loads the processed data into the final table.
The problem with this is I need to clean out the rows that were extracted from the staging table and I'm not sure how I can accomplish this (and I can't just issue a "delete from staging_table" because there maybe new records in the staging table that were not processed), perhaps I can either delete each record as it is proccessed or somehow get the last proccessed identity id from the staging table and delete all records less than or equal to that id.
thanks in advance for any help you can provide, maybe there is an easy way to accomplish what I'm trying to do.

I have a select Script as follows:

, a.Qty AS 'Quantity_Recived'
, b.PC AS 'PC'
, b.PC AS 'PC'
, 'I' AS 'Flag'
FROM TNRInventory.dbo.tInventoryAlloc AS a

LEFT OUTER JOIN ABC.dbo.ZREFRESHTAB AS b ON a.DispenserID = b.Asset
LEFT OUTER JOIN ABC.dbo.TableJoinKey AS c ON a.TitleID = c.TITLE_ID
WHERE (vwMap.DataSourceID = 3) and vwMap.[DataSourceAllocName] = 'I'
group by c.SKU_NO , vwMap.[DataSourceAllocName],a.Qty , b.Profit_Center
order by c.SKU_NO,vwMap.[DataSourceAllocName]
GO
i have to send the result of aforesaid script in batch of 300 records per file (tab delimited text file)
now the file name must be dynamically created as each file will contain 300 records.
I have found some document related to same issue on this url

but still there is a catch.
Can any one guide/suggest me better way to do the aforesaid.

[Flat File Destination [46500]] Error: Data conversion failed. The data conversion for column "Column 0" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page." What does this error mean exactly?
I am taking columns from a flat file source. Then I am adding some new columns then rewriting the file to a ragged file format with fixed column values. I've taken the Destination component off and it works fine. So I know it could be the destination component but what could it be? Any ideas?
I set up a connection file in order to move data from sql to csv files. I should be at the last step, the data flow. but:I don't see any flat file in my destination assistant.
View 23 Replies View RelatedHi all,
I am passing flat file source as a variable to Dtexec Utility. (like package.variables[User::varFileName].Value;"D:sourcedata.txt).
Destination table is having one more column.
I want to add custom value in that column at run time by parameter to Dtexec(User::varDate)
I dont know how to do it, please help me.

Hi,
I have a simple enough task to complete that I can€™t seem to find the answer to.
The task is this €“
Select table x from the database and write it to a flat file complete with that tables column headings.
Now I€™ve managed to set up an ole db datasource and selected the table and I€™ve also linked it to the flat file output. So now I can generate a flat file from the database. However no column headings appear in the flat file.
I can€™t seem to find anywhere (like a checkbox) that will also output the column headings to the flat file.
Now I can add in Headings manually in the properties of the Flat File Destination object but the columns that appear in the flat file don€™t appear to be in the order that I requested them in the SQL.
So the question is how do I automatically have the column headings appear for flat file output (ideally without me having to manually add them in).
If it can€™t be done and I have to use a vb.net script instead then would anyone have an example script of how to do it?
Thanks in advance for anyone who manages to answer this.

Currently we has a database of size about 300G. Because our backup system failed some time past we were left with a transaction log file which grew to about 160G. However our backups are working again and everything is working fine. My understanding is that now the transaction log file is practically empty but the capacity remains at 160G.
When you delete records the deleted transactions are going to get logged to the transaction file. My understanding is when a backup is done these transactions get discarded out of the transaction file.
could I make use of this relatively large transaction file and start deleting transactions without out actually adding to the transaction file size.
The plan is to delete records from logging tables that are not referenced to by any other table without this increasing the transaction log file.For example over a period of a few weeks we can delete a chunk of records from a table. Then after it has completed a backup we can delete another chunk of records out of this table until we have got the table down to the records that we now need.Will this work?
Hi ,
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?
pls give your suggestion
Thanks & Regards

Import.csv file looks like,
TABLE_NAME DESC CODE
tab1 table1 A
tab1 table1 B
tab1 table1 C
tab2 table2 D
tab2 table2 E
tab2 table2 G...
First column values are table names which are already exists in target database. Next two columns[Desc],[Code]Â data gets populate from CSV file to table.
In this scenario, how to load tab1 data into the same table in destination and so on.
Which way will be more standard to accomplish this task? If its a script task using C#, looking for clear script to identify a value changes in the first column.
I finally put together a SSIS package that takes a Text File and successfully imports its data into the right table. My question is, where in the package's properties can I find the option to Delete all rows from Destination Columns prior to Importing. I have looked everywhere in the Package Explorer for this setting. Thanx in advance.

Hi All SSIS experts,
Happy 2008!!!!
I am inserting data into a tab delimted text file using SSIS package.
After data insetion some extra tabs get added between columns in some rows in the text file.
Can we programmatically delete the extra tabs from the text file, if so how to use/implement the code inside the SSIS package?
Any pointer/suggestions are welcome.
Thanks & Regards,
HI,
I have been trying to solve the locking problem from past couple of days. Please help mee!!
Scenario:
--------------
I have a SSIS package in which 2 data flow tasks. 1st data flow task deletes records from a 5 tables and the 2nd data flow task should insert records into 1 of the five tables after the success of 1st data flow task. This scenario runs in Transacation.
The above scenrio in the 2nd data flow task hangs in runtime. It does not complete. with sp_who2 command i could see that there is an intent share lock(LK_M_IS) on the table and the status is SUSPENDED.
I dont know how to come out of this locking. Please help.
Thanks ,

what is the best way to uses ssis to deal with a CSV file that contains a number of records that contain a different number of fields ?
I could just load as a single column delimited by <CRLF> but then I would have to write the code to parse the line, effectively detokenising the columns myself but if that is the case then why uses ssis at all ?
I am copying data from database to an excel file through SSIS. database is MS SQL 2005 and BIDS is also 2005.However, the job doing this task fails every time.As per investigation, the result of the query is more than 100,000 rows and we know that excel has a limit of 65000 rows of data.Is there a way of setting the limit up? or something? a better approach maybe so that everything will be copied to the excel file successfully.

Hey all
I am exporting table rows (based on a query) into an excel file but I don't want to append to the file. I would like to delete the rows that were previously added and then add the new data. The file has column headings and I would like these to exist all the time.
I know how to export the data but don't know how to delete 'old' data rows from excel.
Any guidance will be highly appreciated.
Many thanks,
Rupa
Greetings. I have been trying to develop an SSIS package that updates external data (Visual FoxPro tables) from SQL Server 2005. I have tried this various ways: using various Data Flow task components that flow to an OLEB Destination; using an Execute T-SQL Task; and even trying Management Studio interactively with the OpenDataSource('vfpoledb', etc.) statement. For each of these techniques, I have no problem performing a SELECT from the VFP data. Also, I have no problems performing an INSERT of new records using any of these techniques. However, both UPDATE and DELETE of existing records fail.
Is it possible the the OLE DB driver doesn't support UPDATE and DELETE operations? It appears that I'm not allowed to change or delete existing records, only add new ones. Or, are there other techniques I can be trying?
I am aware that updating FoxPro data can be performed by pulling the data from SQL Server into FoxPro. For our purposes, it would be more convenient if the processes could be initiated and managed from the SQL Server side of things instead.
Thanks much,
Randy Witt
Greetings from a SSIS newbie still on the learning curve...
I have a SQL query OLE DB Source that yields a result set that I'd like to put into a SQL Server Destination, but only those records that don't already exist in the destination.
Is there a recommended (read: easy) way to accomplish this? Perhaps a handy transformation?
I have tried to incorporate a subquery in my source query along the lines of:
SELECT fields FROM table1 WHERE keyfield NOT IN (SELECT keyfield from table2)
which works in design time but fails at the server with a cryptic:
"Error: Unable to prepare the SSIS bulk insert for data insertion."
and
"Error: component "<component>" (16) failed the pre-execute phase and returned error code 0xC0202071."
Don't mean for that to cloud the issue, though. I would appreciate any help given.
Thanks!

Hi Gurus,
We have a SQL 2000 DB1 ( publisher) which is replicated using transactional replcation onto the secondary server DB2 ( subscriber). we have identity columns on the DB1 and we created those tables with 'not for replication' clause. we skipped the following errors in the replication profile '2601:2627:8102:20598'. on DB2 ( the subscriber ) some records are missing in some tables . ( I verified this with record count differences for some tables in both the servers DB1 & DB2.
How to find out what are all the records missing & the cause.
I have listed the msrepl_errors table on DB1 , distribution databases all I'm seeing there are error code 8102 , unable to update identity column.
Any Idea is appreciated.
- Thanks

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!
