T-SQL (SS2K8) :: Load Data From Flat File Source Into OleDB Destination By Changing Data Types In SSIS
Apr 16, 2014I have an source file and i have to load it into the data base by changing datatype of the columns in ssis
View 1 RepliesI have an source file and i have to load it into the data base by changing datatype of the columns in ssis
View 1 RepliesI 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.Â
He hinted that an embedded query does not have this same effect, but I am not sure that is accurate.
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

1 How to get the desired output colums into Excel file without having 'copy of column/unwanted columns' in destination file.
2. How to override the existing file in excel destination.
[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?
Hi,
I've just started looking at SSIS and have encountered what should hopefully be a simple problem to solve. I have a pipe-separated source file that looks like this (I've added Line numbers for simplicity):
Ln 01: HDR|FEED_CODE|31-MAR-2006
Ln 02: Tom|100|Jones|ZZ1 1ZZ|USA
Ln 03: Tom|200|Singer|
Ln 04: Tom|305||Red|Porche ||Lanzarote |Apple|Carrot| | |
Ln 05: Dick|100|Van Dyke|ZZ1 1ZZ|USA
Ln 06: Dick|200|Actor|
Ln 07: Dick|305||Blue|Ford||California |Tomato | |||Beef
Ln 08: Harry|100|Houdini|ZZ1 1ZZ|GBR
Ln 09: Harry|200|Escapologist|
Ln 10: Harryk|305| |Green ||Triumph |Poland|Banana|Sprout| | |
Ln 11: TRL|9
In addition to a header and footer records, this file contains three record types for each person.
Record types are identified by the second column.
Each record type has a different number of columns:
Type 100 has 5 columns
Type 200 has 4 columns
Type 305 has 12 columns
The Row delimiter for all records is the {CR}{LF} character
I've set up a flat file input source and specified {CR}{LF} as the row delimiter for both header and data rows and the "|" character as the field delimiter.
It appears that SSIS is assuming that because the first data row has 5 columns, then everything must fit that format too. So the {CR}{LF} character that separates lines 02 and 03 is interpreted as text rather than a separation character and all remaining | field separators after 305 are interpreted as text containing in the fifth column. SSIS is also complaining that the last row is incomplete.
A bit like this (I've used tildes to indicate column separation):
Tom~100~Jones~ZZ1 1ZZ~USA
Tom~200~Singer~{CR}{LF}Tom~305||Red|Porche ||Lanzarote |Apple|Carrot| | |
I've seen one other reference to this behaviour but the response seemed to be SSIS doesn't know which columns are missing. In this scenario, we don't have missing columns, rather, we have different types of record in a single file. in DTS I would effectively parse the file once for each record type thus:
if cStr(DTSSource("Col002")) = "100" then
DTSDestination("in_Name") = trim(DTSSource("Col001"))
...
Main = DTSTransformStat_OK
else
Main = DTSTransformStat_SkipInsert
end if
...not the most efficient solution I know but the load only runs once a month so this was an acceptable workaround.
DTS was never this fussy but I'm sure this is user error rather than an SSIS limitiion. Can someone please put me straight?
Many thanks,
Greg
I have three tables in data base:
customer
product
sales
And i want to use SSIS package dynamically load data from database into three separate flat file, each table into each file.
I know i got to use for each loop task ADO.Net schema row set enumerator, with OLEDB connection manager, select table name or view name variable from access mode list, but the problem comes, as table name is dynamic then flat file connection is also dynamic, i am using visual studio 2013...
I'm working on SSIS to load the data from flat file to sql server, I'm getting date in below format, but in sql server I have given data type datetime. how to convert below format to 16-01-15 12.05.19.1234 AM.
View 4 Replies View RelatedHi Guys,
I
have a flat file which is loaded into the database on a daily basis.
The file contains rows of strings which I load into a table,
specifically to a column of length 8000.
The string has a length of 690, but the format is like 'xxxxxx xx xx..'
and so on, where 'xxxx' represents data. So there are spaces, etc present in the middle.
Previously
I used SQL 2000 DTS to load the files in, and it was just a Column
Transformation with the Col001 from the text file loading straight to
my table column. After the load, if I select len(col) it gives me 750
for all rows.
Once I started to migrate this to SSIS, I
allocated the Control Flow Task and specified the flat file source and
the oledb destination, and gave the output column a type of String and
output column width of 8000. But when I run the data flow task it
copies only 181 or 231 characters out of the 750 required.
I feel it stops where it finds the SPACES and skips the rest.
I
specified row delimiters or CR, and LF. I checked the file under
UltraEdit and there were no special characters in the file that would
cause the problem.
Any suggestions how I can get it to load the full data?
Thanks
Hi,
I am trying to impliment a SSIS package where data source is a Flat file(.csv) file and destination is a sql server database.
The problem is my data source a flat file which consists of thousands of rows which are manually entered, so there is always a chance that in some rows they may miss a column value while entering data which results in an error.
Example: My flat file has headers like Sln, Name, Age, Designation. While entering data they may miss age and type it as 1,aaa,Consultant,,
Using SSIS package i want to track all row number in the flat file where data is entered wrongly so that i can correct only that row instead of checking all rows each time when my SSIS package throughs an error. I want to get all the row numbers in a sql server database which are wrongly entered.
Any suggestions are sincerly apriciated.
Thanks in advance

Hi 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.

Each day I receive a file with a different name. For example, the name is filename_mmddyyyy.txt where filename_ stays constant and mmddyyyy is the date of the file. The file is always in the same format.
I want to build an SSIS where I pass it this file name. I can write a script to generate the correct file name. How do I build the SSIS so it can accept the input parameter and find the correct file to process?
Thanks
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 have a CSV Flat File Source with a Decimal column - but DataPrecision property is grayed out - why?
View 1 Replies View RelatedI'm having a problem using the Flat File Source while using the underlying .Net classes to execute SSIS Packages. The issue is that for some reason when I load a flat file it Empty's out columns randomly. Its happening in the Flat File Source Task. By random I mean that most of the times all the data gets loaded but sometimes it doesnt and it empty's out column data. Interestingly enough this is random and even the emptying out of columns isnt a complete empty, its more like a 90% emtpying. Now you'll ask that is the file different everytime and the answer is NO. Its the same file everytime. If I run the same file everytime for 10 times it would empty out various columns maybe 1 of those times. This doesnt seem to be a problem while working with dtexec or the Package Executor utility. Need Help!!

View 4 Replies View RelatedHi 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

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!
Hello everybody.
I have a problem with "Flat file"-connection, which I cannot understand at the present. Here is the issue: I've got an ASCII-file containing 233898 lines. I try to read this file in two different packages using two different connections. In the first connection I used default data type - DT_STR of length 50, in the second one I used "Propose types..." feature (with 2000 samples) to detect types which are better matching the reality. And, when I try to load my data, the first connection reads exactly 233898 lines from the file, the second one 203898. Somehow it skips 30000 lines unloaded.
I tried to observe the error output for the second connection - everything goes smoothly and problemless. But somehow those 30000 lines are missed.
Has anybody experienced such a situation? Is the issue known?
Thanks in advance,
A.G.
This question is around how we can get the data types and lengths populated into the flat file source columns.
In Connection Manager, you have your flat file defined. You can choose "Suggest Types...", and the minimum lengths and correct data types will be returned from within the data in the flat file.
Is there some way to automate this data type definition, but coming from the other direction (coming from the destination table that we are loading)?
For example, you have mapped the columns that will be loaded. Can you then reverse engineer the data types and lengths for the columns in the flat file from the destination table?
TIA
Hi,
I'm using an OLEDBSource to select some data and then putting to in a Flat File destination.
However, when I look at the data in the OLEDBSource, they´re like this:
1. id
2. name
3. address
...but in the flatfile it comes out in the wrong order.
How can I fix this?
Thank you so much.
I have a flat file destination that Im sending data to, from an OLE DB data source. There are two records, but for some reason they are both going on the same line in the output. This is after setting the output to fixed width, from comma delimited.
Help ?
I am running my package in sql server 2012, in which i am giving network path for flat file destination. And its working fine. But if i give m local path, its giving me  error " cannot open data file" ...
Nothing is wrong with package.
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
I'm getting a bit lost in SSIS. I've got an Excel source file that I'm trying to load into a table. I keep getting validation errors that warn about not being able to convert between unicode and non-unicode string data types.
I'm trying figure out where I have to change this and am frankly confused. It seems SSIS is selecting various columns as unicode/WSTR data types, but I want them to import as regular string types.
On the Data Flow tab in SSIS, I right-click on the source Data Flow component (the Excel file) and select Show Advanced Editor. Then on the last tab, Input and Output Properties, there's a tree view for the Excel output. There are "External Columns" and "Output Columns" containers in the tree view.
I tried setting some of these but they don't seem to "take". Do I need to change the data type for each column under both the External and Output columns?
That seems like a lot of work! And, as I say, I tried setting some, but I still got the same validation errors. So, then I go back to this spot (Advanced Editor -> Input and Output Properties tab) and my changes seem to have been lost.
Any help would be appreciated!
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 ??

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,

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
I am having difficulties loading data from a flat file to a SQL Database. I am able to load some data but the rest gets kicked out for the following reasons:
1 – The field is varchar 50 and I would like to convert it to a date field
2 – The field contain periods (.) (Only 1 period in each row)
3 – The field contain blanks (NULLS)
How do I create a derived column that will bypass blanks (Nulls) and remove periods (.) in each row then convert column to a date field in SSIS? Looking for steps to create a derived date column using SSIS (derived task); convert it to a date column (09-19-2015); use functions to redirect the nulls and possibly remove the period (.)?

Hello guys,
here is my issue.
I created a ssis package which exports the data from oledb source to flat file (csv format). For this i have OLEDB source and Flat File as destination. I generate the file and filename dynamically with the column names in the first row. So if the dynamically generated file name already exists , then i want to append the data in the same existing file. But I dont want to append the column names again. I just want to append the rows to the existing rows.
so lets say first time i generate a file called File1_3132008.csv.
Col1, Col2
1,2
3,4
After some days if my ssis package generates the same file name i.e. File1_3132008.csv, this time i just want to append the rows to the existing file. So the file should look like this-
Col1, Col21,23,45,67,8
But instead my file looks like this if i set Overwrite propery to false
Col1,Col2
1,2
3,4
Col1,Col2
5,6
7,8
Can anyone help me to get the file as shown in the highlighed
Any help would be appreciated .
Thanks
Hello !
Please, this is an urgent call; May be someone issued the sama probleb I do :
When I'm trying to import a XML file, that contains diffgram, using the XML Source task in SSIS, I choose an Inline Schema Option - everything goes well...the tables and columns are displayed, and the Import task into a Database's table succeds.
The problem is that , it doesn't load any data into the table, though there are plenty .
