Execute A Flatfile Source To Oledb Destination For Each File In A Folder.

Jan 24, 2007

Hello, I wanted to do the following.

Copy a full directory from source to destination (Done)

then for each file on the destination directory,it must process that file and insert rows on the table.

So I created a foreach loop, and created a varriable aclled CURRENTFILENAME, and assigned it into the foreachloop to index 0.



Inside the foreachloop I created a dataflow task, in the dataflow task I dragged a flat file source and an oledb destination, but I noticed that the flat file source requires flat file manager, and the flat file manager requires a unique FILE NAME. I cant put this c:copia*.txt.

I took a loot at flat file source properties and it has associated the flat file manager, but I can not assign the filename to the variable from the foreach.



Any ideas please

Error When An OLEDB Source Points To An OLEDB Destination.

Oct 10, 2006

Hi all,

I got an error when i do an OLE db Source pointing to an sql 2000 database and executing a sql query inside the OLE Source. The ole source will point to an OLE DB destination which is an sql 2005 database.

But i got the below error:

SSIS Programmaing - How To Map Flatfile Source Columns To SQL Server Destination?

Dec 7, 2007

Hi,

I am new to SSIS programming and trying to export data from a flatfile source to SQL server destination table dynamically. I need to get the table schema info (column length, data type etc.) from SQL server table and then map the source columns from flatfile to destination table columns.

I am referring to one of the programming samples from Microsoft and another excellent article by Moim Hossain. Can someone help me understand how to map the Source columns to destination table columns depending on table schema? Please help.


Thanks

Data Flow Task - OLEDB Source / Destination

Nov 9, 2006

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.

OLEDB To Flat File Destination - Comes Out In Wrong Order

Jun 8, 2007

Hello,



My OLE DB Source is getting data from the following column types:

ID varchar(50), Name varchar(100), Date datetime, Currency char(3), Cost numeric(30,10)



My OLE DB Source outputs my information in the following order when I click Preview:

ID Name Date Currency Cost



When I connect the OLE DB Sorce to a Flat File Destination, it comes out in the wrong order.When I examine the "line" between them (Data Flow Path Editor) I get:



Currency DT_STR Length: 3

ID DT_STR Lenght: 50

Name DT_STR Lenght: 100

Date DT_DBTIMESTAMP

Cost DT_NUMERIC



What is the easiest way for me to change this so the Flat File Destination will output my data in the same order as the OLE DB Source:

ID Name Date Currency Cost



Thank you very much!

Copying Table Data From SQL Server 2005 To SQL Server 2000 - Very Slow When Using OLEDB Source And Destination Sources?

May 8, 2006

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

How To Read File Information From Source Folder!

Mar 6, 2008

I am new to SSIS and I am trying to do following thing using WMI Reader Task.

I have developed SSIS package which import data from flat files.
Now I have to add following functionality to SSIS package

Before SSIS package load data I would like to check If there are all files in source folder and check the files are with current date.
If both condition true then only load data.

After some research i found that WMI uses specialized query language known as WQL, which is similar to SQL, to obtain information on files and directories.

Also i found that Under WMI Reader Task editor properties you can write WQL query to receive file information from source folder.

Can Anyone suggest me What WQL query i have to write to retrive file information from Source folder?

Or

Any Other suggesion i should approach?

Please advise me!...Any help would really appriciated...

Integration Services :: File System Task Move Directory Deletes Parent Destination Folder

Mar 12, 2013

I attempted to use Move Directory to move the contents of one directory to another.  I encountered the 'different volume' issue that others have experienced.  While this error is frustrating I can work past this particular issue. My more pressing question is why is the move directory command overwriting a destination directory?  

When I setup the Move directory file task I provided two vars to hold src and dest location:

dest var:  estserveroutput
src var: devserverdev estfiles
Set overwrite destination = TRUE

Why would Move Directory overwrite output folder at destination?  Shouldn't it only overwrite if the testfiles directory exists at destination?  This is very frustrating since I cannot find enough information in the official documentation to understand what is happening here.  

Is it just me or does the documentation for Move directory seem.....incomplete?

Decimal Formatting From OLEDB Source To Flat File

Feb 21, 2006

I have a
table with column (call it Rate) defined as decimal(18,4). This column
can have any positive decimal value. When the value is less than 1
(e.g. 0.1234) strange things are happening in SSIS.

To set the scenario ...

If I do a select in Management Studio, the value is correctly displayed as 0.1234

If I do the same select from the command line via OSQL, I get .1234

If I do SELECT CONVERT(char(6), Rate) from OSQL, I get 0.1234 (which is what I want)

In SSIS I have an OLE DB Source which defines the SELECT statement to use, and that maps straight to a Flat File Destination.

The
default column type in the flat file connection manager is DT_NUMERIC,
Precision 18, Scale 4. I Set InputColumnWidth to 6 as that's how I need
it in the flat file. The value appears in the file as .1234

I
change the SELECT in the OLEDB Source to apply the CONVERT(char(6),
Rate), and change the column type in the connection manager to DT_STR
length 6. Output is *still* .1234

How can I get the output column in my file to show 0.1234 ??

Greg.

Merge Data From Oledb Source And Flat File

Feb 26, 2008



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

Flatfile Destination Expression Problems

May 11, 2007

Hi:

Am trying to write SQL data to multiple flat files.

I use a For Each loop,

store field Values in variables

construct a fileName(variable as expression) for each row,

then create a text file for each row in resultset, (Filesystem task)

and then try to fill each file from a SQL Source to a Flatfile Destination.

Destination.connectionString=Filename.



Works ok for creation of Text Files, so I know my fileName variable is getting evaluated for each iteration.

But the flat file connection manager is stuck and evaluates to the static part of my expression.



What am I doing wrong?

TIA

SQL Server 2008 :: Use Folder Name As Database From Batch File To Execute Files

Jul 17, 2015

I've been struggling with this issue,

1) Test--FolderName (This Test folder name should use as a database name for below sub folders)

a)Create--Sub Foldername
i)create.sql
b)Alter---Sub FolderName
i)Alter.sql
c)Insert---Sub FolderName
i)Insert.sql

[Code] .....

The scripts need to be run in order. So script one needs to run first folder in that sub folders after that next second folders etc..

Is there a way to create a bat file that automatically runs all these scripts, in order against, the databases they need to?

The databases that they need to run against have the name of the database at the beginning of the name of the folder.

Date Formats From OLE DB Source (SQL) To Flat File Destination

Oct 23, 2007



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.

How Do Flat File Source And OLE DB Destination Work Behind The Scenes?

Nov 12, 2007

Good day everyone,

I have implemented a simple package that has only a Data Flow Task in the Control Flow. The corresponding Data Flow Components are as follows (in the correct order):

1. A Flat File Source adpater which parses a file containing circa 1 million rows.
2. A Script Component that generates IDs for two of my destination tables.
3. A Mulicast Component that distributes all the columns retrieved from the source file as well as the 2 generated keys.
4. Four OLE DB Destination adapters where I insert the data from the different columns together with the generated keys as primary or foreign keys respectively.

My questions are mainly about how the "Flat File Source" and "OLE DB Destination" work behind the scenes.

Questions:
A. "Flat File Source" adapter:
Does the "Flat File Source" adapter load all the rows from the source file into the memory and then start pushing the rows one by one into the data flow?
My concern is actually about the huge sizes of my import files, which might eat up the memory.
Or does the "Flat File Source" adapter load a certain number of rows, pushes them into the pipeline and then fetches the next batch based on a certain configuration?

B. "OLE DB Destination":
I have set the four OLE DB destinations to "Fast Load" with a commit size of 5,000.
Can I ever run into the problem of having for instance 10,000 records inserted in Table1, but only 5,000 inserted in Table2. The error case I am thinking about is as follows:
After the second commit on Table1, an erroneous record occurs during the insertion in Table2. Thus, the second commit for Table2 gets rolled back and the whole package fails.
In this case, I get an inconsistent state in my database.
In other words, how can I synchronize the commit operation in all my destination tables, s.t. they either all commit the same batch or all do not commit it?

Thank you in advance for your support.

Regards,
Samar

Integration Services :: SSIS OLEDB Data Source - Flat File Generation

Apr 20, 2015

I am working to archive some old data from a data warehouse using SQL server and SSIS.  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.  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 cannot start until the full procedure processing is complete; i.e. the proc churns out its' result set in one big chunk. 

He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.

Only Create Destination Flat File When There Are Rows Returned From Ole DB Source

Oct 25, 2007

Hi,

I have a data task with the following requirements:
1) Run query against database to retrieve rows
2) Add header and footer row to the result set. The footer row must contain a count of the records.
3) Write the rows to a fixed width file if there were any data rows

I have got to the point that I can create the file (using a set of tasks that includes derived columns, sorts, aggregation and merges). However the file is created regardless of whether there were data rows returned.
I can't check the row count before proceeding as this isn't set until the data task ends. And if I try to split them into separate data tasks (so that I can access this variable and perform conditional execution) it becomes harder to access the original rows.

Do you have any recommendations on the best way to achieve this?
It all seems to be very complex and I'm starting to feel that it would be easier to do this outside of SSIS...
Please help me to keep the faith!

For those interested this is a slightly simplified version of what I have so far (all within a single data task):

1.Run dummy sql to create header row 2.Run main SQL to retrieve rows
| |
| 3.Multicast
| | |
| | 4.Create footer row by doing sum() in aggregate task
| | |
| 5.Merge body and footer
| |
6. Merge header with body and footer
|

7. Create fixed width file

Skip A Row In The Flatfile Source

May 20, 2008

I am importing a flatfile and cannot seem to deal with an issue that seems quite simple.

The files have a header row with column names and those rows start with '#'

However sometimes this header row will also be present in the middle of the file.

The Source tries to parse this row and fails

Is there any way to tell the flafile source to skip rows that start with a particular character like comment rows?

Using the disk as a temporary storage for the flatfile is prohibited.

Does anyone have any suggestions on how to solve this?

SSIS..Problem Parsing FlatFile Source

Dec 8, 2006

I'm trying to Move data from a FlatFile Source to an SQL destination

row delimiter {LF}
Column Delimiter is "comma"
Number of columns in each row : say 7

Example Rows

Example 1:
1,1,1,1,1,1,1{LF}2,2,2,2,2,2,2{LF}3,3,3,3,3,3,3{LF}4,4,4,4,4,4,4{LF}

Example 2:
1,1,1,1{LF}2,2,2,2,2,2,2{LF}3,3,3,3{LF}4,4{LF}

There is no problem parsing Example 1:
With Example 2.

The Old DTS used to parse fine..when it encounters a row delimiter it fills the rest of the columns with null...

While the New SSIS flat File source is following column count in each row...and is considering " 1{LF}2" as column item rather than a row delimiter...

Is there any way around it or is it a bug?

Thanks for any help in advance
