Combining Multiple Tables Into A Single Flat File Destination
Aug 21, 2007
Hi,
I want to combine a series of outputs from tsql queries into a single flat file destination using SSIS.
Does anyone have any inkling into how I would do this.
I know that I can configure a flat file connection manager to accept the output from the first oledb source, but am having difficulty with subsequent queries.
e.g. output
personID, personForename, personSurname,
1, pf, langan
***Roles
roleID, roleName
1, developer
2, architect
3, business analyst
4, project manager
5, general manager
6, ceo
***joinPersonRoles
personID,roleID
1,1
1,2
1,3
1,4
1,5
1,6

I have a package that contains three database tables (Header, detail and trailer record) each table is connected via a OLE DB source in SSIS. Each table varies in the amount of colums it holds and niether of the tables have the same field names. I need to transfer all data, from each table, in order, to a flat file destination.

Here is the Scenario.
I have a flat file with name "Employee.txt " (Full url: C:Employee.txt) .The File content is like this
Anil,Engineering,1997
Sunil,Sales,1981
Kumar,Inventory,1991
Rajesh,Engineering,1992
(Note: Items are Comma Seperated)
Now, i have a SQL Server database called "EmployeeDB" which has 2 tables "TblEmp1", "TblEmp2".
The Table is like this.
TblEmp1 : Columns
EmpName EmpDept EmpjoinDate
TblEmp2 : Columns
EName EDate Edept
using integration services (SSIS) i need code(vb.net or c#) to Create a dtsx package so that i can push the flat file content to these 2 tables.
And the condition is :
After Executing the package Data loaded in TblEmp1 should be like this
EmpName EmpDept EmpjoinDate
Anil Engineering 1997
Sunil Sales 1981
Kumar Inventory 1991
Rajesh Engineering 1992
(No change in order compared to source)
And Data loaded inTBLEmp2 should be like this
EName EDate Edept
Anil 1997 Engineering
Sunil 1981 Sales
Kumar 1991 Inventory
Rajesh 1992 Engineering
Now, i know that we need to do like this in wizard
1) Create a flat file source component.
2) Create flat file connection and set the properties of flat file (delimeters and other things)
3) Create a Multicast Component.
4) Create a Path between Flat file source and Multicast.
5) Create 2 destination component(each for a table).
6) Create path from multicast to 2 destination components
7) Create a OledbConnection and set table names for 2 destination components..
7) Now,i have to do mapping for destination1.8) Now, i have to do mapping for destination2( this mapping will be different from mapping done for destination1 because iam not inserting the data in the same order in which iam doing for TBLEmp1.
I have done it in wizard.I need to do it through code and i know that its not complicated.Please find the attached file with this mail.i have attached a screen shot of how i have done in wizard.The main problem is Mapping differently for 2 destinations from source.for 1st one we can have a forloop for mapping.but for 2nd one iam confused!!

Hi,
I am testing SSIS and have created a Flat File Destination. I defined the Flat File Connection as New for the first time and it worked fine. Now, I would like to go back and modify the Flat File Connection in the Flat File Destination Editor, but it allows only to create a New connection rather allowing me to edit the existing one. For testing, I can go back and create a new connection, but if my connection had 50-100 columns then it would be an issue to re-create it from scratch.
Did someone else faced this issue?
Thanks,
AQ

I am transferring data from an OLEDB source to a Flat File Destination and I want the column width for all of the output columns to 30 (max width amongst the columns selected), but that is not refected in the Fixed Width Flat File that got created. The outputcolumnwidth seems to be the same as the inputcolumnwidth. Is there any other setting that I am possibly missing or is this a possible defect?
Any inputs will be appreciated.

Hi all,
I m using SSIS and i am transfering the data from Flat File Source to the OLE DB destination File. The source file contain some corrupt data which i am transfering to the other Flat file destination file.
Debugging is succesful but i am not getting any error output in the Flat file destination file.
i had done exactly which is written in the msdn tutorial of SSIS.
Plz tell me why i am not getting the error output in the destination flat file?
thanx

So here's the issue
16 flat files all fixed width. Some over 350 columns.
Open flat file 1
extract id and go see if its in table 1, if true update table 1 with first 30 columns
otherwise insert into table 1 first 30 columns.
goto table 2, lookup id, insert/update next 30 columns...etc..etc..for 10 different tables
So I've got my flat file source, I do a derived column to convert the dates, i've got a lookup for table 1, then 2 ole db commands, 1 for update if lookup successful, 1 for insert if lookup fails.
How can I pass the id as a param into the update command so it updates where x = 'x'
also I need a pointer on doing the next lookup, eg table 2, would I do this as some sort of loop?.
If you can help great, but, please don't just reply with "I'd use this object"...then no explanation of how
v.v.frustrated newbie to SSIS

Probably a stupid and regularly asked question but I can't seem to find an answer, so here goes,
we have 16 .txt files, some with over 350 columns.
That info from each individual file needs importing to multiple sql tables.
need to look at sql table1 does record exist? if not create new then add in data once its been transformed eg datetime from yyyymmdd into datetime values [managed to get this using derived column] for first 20 columns, otherwise do update for the 20 columns...
then look at sql table2 and repeat for next n columns....
So I was wondering is it going to be better to write this as a dtsx package? if so can you point me to an example
or should I just write the code as part of a code behind page that scrapes the info and does a standard update/insert procedure?
Any help would be welcome.
thanks

We are trying to use SSIS Import export wizrd to import the flat files (CSV format) that we have into MS SQL Server 2005 database tables. We have huge number of CSV files. Is there a way by which we can import these flat (CSV) files in to corresponding SQL server tables in a single shot. I would really appreciate this help as it is painful to convert each and every file using the Import Export wizard.
Thank you very much,
Regards,

I need to export data from multiple tables into one single file. The big problem here is that the tables will have different column types.
I am attempting to create something that allows users to be able to send me the contents of their tables's, through either email or ftp. I would prefer to make it easier for them so they only have to deal with one file, instead of the multiple files that bcp and dts create when exporting from multiple tables.
I was thinking of using DTS or BCP and then join (append) the files (either zip them or append the files together in some fashion), but I was hoping that there was an easier method out there.
Any ideas on how I may accomplish this would be greatly appreciated.

The goal is to produce a single PDF consisting of a number of subreports. Some are landscape, others are portrait. The subreports may also be run as independent reports. The master report that contains them defaults to the width of the widest subreport, which is landscape. This causes all portrait subreports to spill over producing blank pages. Are there any work-arounds to concatenate multiple, single report PDFs into a single PDF and have page numbering too?
Thanks!

I joined these two tables and it pulled up the proper amount of records. If you check out the image you will see what the results are for this query.
Now all I need for this part would be to roll these up where I have one row per ProgramID and all the AttributeNames' together in a AttributeNames column for each id.
EXAMPLE: All in one row.
ProgramID | AttributeNames
887 | Studydesign, Control Groups, Primary Outcomes.
I have attached an image of the SQL VIEW that I need to modified so it does this.
THE QUERY:
SELECT TOP (100) PERCENT dbo.tblProgramAttributes.ProgramID, dbo.tblProgramAttributes.AttributeID AS PAattributeID, dbo.tblAttributes.AttributeID,
dbo.tblAttributes.AttributeName
FROM dbo.tblProgramAttributes INNER JOIN
dbo.tblAttributes ON dbo.tblProgramAttributes.AttributeID = dbo.tblAttributes.AttributeID
WHERE (dbo.tblProgramAttributes.AttributeID NOT LIKE '%ProgramType%')
ORDER BY dbo.tblProgramAttributes.ProgramID DESC

I have a delimited text file with 650+ columns. The sum of the column lengths of a single row, if fully populated, exceeds 30K bytes. The "killer" fields lengthwise are the "Description" fields. If they were removed from the input file, the remainig columns would occupy about 5000 bytes, which is within SQL max row length.
Can SSIS be used to created these two tables? (one without description fields, the other with those field but arranged vertically in the table rows).
The fundamental issue is I can not import a single file row into a sql table because that row length could exceed the max byte count for a row.

Need to know how I can get the dynamic filename created in the FlatFile destination for insert into a package audit table?
Scenario: Have created a package that successfully outputs Dynamiclly named flat files { Format: C:Test’Comms_File_’ + ‘User::FileNumber’+’_’+Date +’.txt’
E.g.: Comms_File_1_20150724.txt, Comms_File_2_20150724.txt etc} using Foreach Loop Container :
* Enumerator Set to: “Foreach ADO Enumerator” with the ADO object source variable selected to identify how many total loop iterations there are i.e. Let’s say 4 thus 4 files to be created
*Variable Mappings : added the User::FileNumber – indicates which file number current loop iteration is i.e. 1,2,3,4
For the DataFlow task have a OLDBSource and a FlatFile Destination where Flat File ConnectionString is set up as:
@[User::Output_Path] + "Comms_File"+ @[User:: FileNumber] +"_" + replace((DT_WSTR, 10) (DT_DBDATE) GETDATE(),"-","")+ ".txt"
All this successfully creates these 4 files:
Comms_File_1_20150724.txt, Comms_File_2_20150724.txt, Comms_File_3_20150724.txt, Comms_File_4_20150724.txt
Now the QUESTION is how do I get these filenames as I need to insert them into a DB Audittable. The audit table looks like this:
CREATE TABLE dbo.MMMAudit
(
AuditID INT IDENTITY(1, 1) NOT NULL,
PackageName VARCHAR(100) NULL,
FileName VARCHAR(100) NULL,
LoadTime DATETIME NULL,
NumberofRecords INT NULL
)
To save the Filename & how many records in each file in our Audit Table, am using an Execute SQL Task and configuring it as this:
Execute SQL Task
Parameter mapping - Mapped the User Variable (RecordsInserted) and System Variable( PackageName) to Insert statement as shown below
SQLStatement: INSERT INTO [dbo].[MMMAudit] (
PackageName,NumerofRecords,LoadTime)
(?,?.GETDATE)
Again this all works terrific & populates the dbo.MMMAudit table as shown below BUT I also need to insert the respsctive file name – How do I do that?
AuditID PackageName FileName NumberOfRecords
1 MMM NULL 12
2 MMM NULL 23
3 MMM NULL 14
4 MMM NULL 1

There are two EXCEL sources one destination table. Each record in the destination should be populated with 2 columns from one source and 2 from other source.
Source 1:
ID Name
1 abc
Source 2:
Address Location
232/2 xyz
Destination:
ID Name Address Location
1 abc 232/2 xyz
I tried using UNION ALL transformation but it fetches 2 seperate records (assuming that one record in each source). How to achieve this without using SCRIPT component?
TIA

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

I am using SSIS to create a weekly data extraction that will be emailed to an external agency. I can extract the data, create the file and email it without any problems but I want to compress and encrypt it before I send to give some measure of protection to sensitive data it would contain.
If I did this manually, I would simply use Winzip to compress and encrypt the file to be sent. How can I achieve a similar result programtically?

Hi,
I am trying to access from OLE DB source. And based on one of the columns, I need to write the data to a Flat File Destination.
For Example,
CustID, ProductID, Product Name, Product Description
Say I am going to write to a different Flat File for every product. So if there are 10 products in the data. There should be 10 Flat Files. Also the file name should include the Product Name And Product ID.
It is being done in a single Data Flow Task.
Right now the Property Expression for the File Name is which is not working)
Code Snippet@DestFolder + [Data Conversion].ProductID + @TodaysDate + ".txt"
The ProductIDs are in the ascending order. Any help or guidance?
Thanks

Hii all.
quite urgent... I have 3 matix tables.. all the same row headings. I need to be able to make these visible/invisible depending on the user parameters. The reason for this, if a user hides table on the left.. the middle table needs to show the row headings. and last table must not.
The problem:
When making the row headings invisible it doesnt exactly chop off the textboxes... so the tables look disjoint.. and a big gap appears between both tables...
Is there a way to join these tables without leavings gaps ?
any help is appreciated.

Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob

I have a database app, and we're implementing various data export features using SSIS.
Basically, it's a couple of straight extracts of various recordsets/views, etc. to CSV (flat files) from our SQL Server 2005 database, so I'm creating an SSIS package for each of these datasets.
So far, so good, but my problem comes here: My requirements call for users to select from a list of available columns the fields that they want to include in their exported file. Then, the package should run, but only output the columns specified by the user.
Does anyone have any idea as to the best way to accomplish this? To recap, at design time, I know which columns the users will have to choose from, but at run time, they will specify the columns to export to the flat file.
Any help or guidance here is greatly appreciated

Here's what I want to do -
Dynamically load a flat file from a dynamic source table-
The source table metadata is known via the SYSOBJECTS and SYSCOLUMNS tables- I can pull the column names, type and lengths from these tables based on the table name. (my goal is pretty simple- pull data from a table in our database, and save it down to a flat file)
Would this be enough to dynamically create the destination flat file? If so, how do I do it?
Thanks

Hi,
I have a dataflow task with two components: OLE DB source --> Flat File destination
In the OLE DB source, I am accessing a view, not a table.
However, when I attempt to map the view's input columns to the flat file destination columns, the screen is completely blank. There's none of the usual drop downs that let you select the column name, nor can I drag and drop the input column from the upper pane to the lower pane.
Is there a trick to doing this?
Thanks

Currently we're working on an SSIS package to extract data from a SQL Server database to several fixed width flat files.
Some of the data needs to be formatted/converted in a certain way
DateTimes need to be formatted in ISO8601Booleans need to be 0/1 instead of False/True...Has anybody any idea what the preferred approach (best practice) would be to do these conversions?Convert everything in the select query? What about readability of your query?
Do it somewhere in the package? If so, how?....

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
Darrell
