How Should I Change The Source File Name Every Time During Dataflow Task Using Ssis
Apr 4, 2008
Hi,
I am using SQL Server2005 for SSIS. I want to change the source connection dynamicaly evertime.
Let me clear, I have to extract some column from excel to MS-Access. I am using Data Flow Task and able to successfully complete the job. But problem is that, whenever a new file comes , i must have to reconfigure my Excel Source.
All the time column in file are same, so no need to worry about mapping but how can my package select a file automatically.
I have a directory, suppose "C:dpak". I should able to pick the filename and sheet name from this directory every time when my package will execute.
I have implemented a package to load multiple files to a destination. Since the source was a txt file, i have created as flat file source. However now we are getting files in excel format as well.
Is there anyway the source gets changed dynamically based on the file extension, output of the foreach file enumerator? I can think one solution to have 2 dataflow tasks based on precedence constraining and expression one is for .txt and other one is for .xls.
I am trying to use an XML Source on xml data from an XML webservice, I am putting the document into a variable the trying to import the data from there with the XML Source, but I am getting an error telling me that truncation occured
The Error is "[XML Source [1]] Error: The "component "XML Source" (1)" failed because truncation occurred, and the truncation row disposition on "output column "linking" (1579)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component."
The linking column mensioned in the error is sometime quite a long string but there is nowhere in the XML Source editor to change the size.
I need to create a ssis package. I want to import the data from a flat file to a table.
Lets say, the table has 5 columns -- col1, col2, col3, col4 , col5.(Assume that all columns can be NULLABLE) The datafile contains the data related to only three columns say col1, col2, col3. So when I use dataflow task to import the data from the file to the table, I will only get three columns, col1, col2, col3. Columns col4, col5 will be NULL. However, I want to populate columns col4, col5 with some values which are stored in the variable.
I have problem to extract data from DB2 table using SSIS dataflow task with OLEDB source selecting the data access mode with command. Here is the scenario.(Note:If I select the data access mode as a table then it works fine.)
If I use the data access mode as SQL Command then it is not working. i.e. the flow stays yellow in controlflow nothing happens in dataflow and I noticed the SQL dumper and proc completes. I couldn't find any log to verify the issue including the package execution results.Any of your thoughts will help me to resolve this issue.
I am using execute sql task to run a stored procedure in oracle database which returns a resultset. This works. Now I need to send the ouput to a destination table in a sql database. Should I use for each loop to pick the resultset and insert it into the destination one by one (which I dont think is a great idea) or is there a better way to accomplish this task (in data flow task) ?
When I use dataflow task instead of execute sql task, the main issue is I am not able to see the output columns when I execute an oracle stored procedure, but when I see the preview I can see the resultset . But I can see the output columns for a sql server stored procedure.
I have a problem whit loading XML-files into SQL server.
I iterate over the XML-files with the "for each file" component and use the XML source within a Data flow task. This works great until the file count got bigger. After say 1000 files the XML source returns error 0x8007000E. I think this means out of memory. Does anyone have an idea how to solv this. The load must be able to handle up to 5000 files in one batch.
I have implemented a custom source component that can be used as the data source in the Data Flow task.
I have also created a custom UI for this component by using the IDtsComponentUI .
But my component does not have the capability of setting the custom properties via the DTS Variables using the Expression Builder.
I have looked around for samples on how to do this, but I can only find samples of how to do this for custom Control Tasks, i.e. IDtsTaskUI.
My question is, How can implement the Expression Builder in my custom Source component + custom Source UI. Or do you know of any samples which I can look at.
I am using a Data Flow task which copies data from an Excel Source to a SQL Database Table Destination. From 15 columns I require only 10 columns to be imported to the DB Table. So I have mapped those colums. In SQL DB there is a colum called say X, whose value should be the "Remedy" for all the columns which are imported. Is there any task that can achieve it.
I need to write back to a legacy system in the form of flat file --the first row would be a header and the remaining rows would be the actuals rows of data--each field would have a column delimiter of , and a row delimter of CRLF.
The source is a SQL Server 2005 table.
Im looking for a good example of a script task in the dataflow section that writes to a file.
Can anyone show me the code how to do this or point me to a link.
I am trying to create a SSIS package that will create a csv of a dataset for daily events in the database. However there will be days that there was no activity and thus an empty dataset. The package still runs fine but I want to stop the package if the dataset is empty.
FLOW:
DATA FLOW task: get daily data and put in CSV file
FTP TASK: upload the file to FTP server
MAIL/Copy file task: Move the file and then send a confirmation mail on task completion status.
Pretty simple and it all works great, I do have a few complexities in there. What I would like to add and I am at a loss is at the beginning, if the OLE DB Task resultset is empty then move to Mail Task otherwise process normally. I have tried conditional split, derived columns, the only thing I haven't tried in Script task and am not sure about that yet.
I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file.
Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns in it. These files needs to be migrated to SQL tables using the optimum way.
Which is the best way to setup the Dataflow task for this requirement?Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
New to SSIS and dts. Stumbling along on this one, really looking for resources and help.
I have a flat file, i defined through connection manager
and (for now) a fixed destination excel file I defined in connection manager.
My dataflow, is pretty simple, mapping two fields to each other an amount field and a phone field in a flat file source and excel destinatinon.
the amount column is formated as a number in the excel, and a currency in the connection and both input output properies.
A few questions,
1. why do cells on the excel show up with that green wedge on the upper left? appears to be a formating issue.
2. in the flat file, my amount field does not have the decimal, what would be the best way to apply that? it's should be implied.
3.Everytime I test the SSIS package, it keeps appending to the excel (it actually does not even work right on the second run). What's the best way to have it write to a fresh file? have an ssis script task copy the file from an empty template?
4. Id like to remove the last row? what's the best way to do that?
I have created a File System task which is contained in a Foreach Loop Container. I have .bak files that are populating a directory from a maintenance backup plan.
There is a point where I need to delete the .bak file's after I've zipped them all up.
How do I set the SourceVariable to read through the directory and pick up just the .bak file's in the directory to delete.
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)
I have a source files folder where the files generated everyday. My goal is pick the latest file and copy this single file to another folder. I used the Foreach loop container and got the latest file and stored the file name to a varible i.e. LatestFile Then i want to use the File System Task to copy this to the destination. On the beginning, I could not setup the Latestfile since I don't its name then, so when I setup the Source Connection property of the File system task, it is not allowed to leave the SourceVarible as blank!
I am a relative newbie to SSIS. I have been tasked with writing packages to import data from our clients. We have about 100 clients. Each client has a few different file formats. None of the clients have the same format as each other. We load files from each client each day. Each day the file name changes. I have done all of my current development work with a constant file name in a text file connection manager.
Ultimately we will write a VB application for the computer operator to select the flat file to load and the SSIS package to load it with. I had been planning on accomplishing this thru the SSIS command line interface. Can I specify the flat file to load via a variable that is passed through the command line? Do I need to use a Script Component to take the variable and assign it to the connection manager?
Is there a better way to do this? I have seen glimpses of a VB interface to SSIS. Maybe that is a better way to kick off the packages from a VB app?
hi all, i'm facing a small problem with xml file source. let me explain the scenario!
we have 4 source xml files with same format, each file has around 25k rows of records.
XML Source Derived Columns Data Conversion Conditional Split OLEDB Destination
its executing fine. once we change xml file source (second xml file with same xsd), all other components are showing errors. the error is that
Error 21 Validation error. Staging: DTS.Pipeline: input column "LateRsnCd" (17917) has lineage ID 19380 that was not previously used in the Data Flow task. OnTimeOrderEntry.dtsx 0 0
lineage id has changed it seems, when we are giving new file as xml source. of course xsd is same, but its not taking with names. to resolve this, if we open that errored task, select all, map using column name--> apply. its getting mapped with the columns as it is in the input. still the conditional split will show the error. if we open the conditional flow and give ok, the error has gone, i think some meta dat change has occured in the opening task and giving ok.
what could be the possible probelm and how to fix it? one more doubt, how can we include xml source in the configuration file? since it doesn't have connection manager, i'm struggling with it for dynamic file selection for xml. i dont want hard code the source file path (as it reside in the server) in the poperties of the xml source task. can i have some suggestions 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.
I have a table (source file) where all sourse file(its all text file) name and location stored. i have a dts packeage, through this package all the sourse file will upload. So I need to dynamically change the source file name in dts packages.
2: Dataflow Task: Datareader--Script componant--OLE DB Destination (SQL Server 2005--a single table --always around 600,000 rows)
How do I set up a transaction where if there is a failure the Truncate Table command will roll back---and the OLE Destination (A single SQL Server table) will be left the same as before the load started.
Another question with that volume of data --600,000 rows will a truncate table be pratical in a transaction
A common issue that I run across with clients is they want only want to process a file if it's finished transmitting to the server. This SQL Server 2005 task reads the properties of a file and writes the values to a series of variables. For example, you can use this task to determine if the file is in use (still be uploaded or written to) and then conditionally run the Data Flow task to load the file if it's not being used. You can also use it to determine when the file was created in order to determine if it must be archived.
I have a simple package, which reads a flat file source, does some transformation, and outputs to a flat file destination. The package runs as a SQL Agent job, so I have the flat file source and OLEDB connection ticked and configured on the data sources tab.
What I would like to do is get hold of the flat file source connection string property from inside the package at run time, and use it to set the flat file destination connection string using property expressions.
The easy option is to set the destination in the agent job, but I'd like to add a date/time stamp to the destination filename.
Running SQL 2008. Trying to copy data from one table into another table using SSIS Import/Export Wizard. Now, when I do a straight "Copy data from one or more tables or views", no problems. But when I use the "Write a query to specify the data to transfer", it will not let me get anywhere.
My source table has a field that is setup as "time". It has data, and no problems with the field. I even replicated my destination table structure exactly. But when I try to use the Import & Export wizard, for that one field I get an error stating the source field is unknown and it is labeled as "-1" instead of "time".
I found a couple of of workarounds. One is to cast the source field "time" as "datetime", and then end up with a "datetime2" field in the destination table. Works, but not what I want to store in that field. Second workaround is to use TSQL and use a "INSERT INTO...SELECT...FROM..WHERE.." statement. This works, and gives me the desired results with all data types being same in source and destination, but is a slight pain in the rear end.
I just want the Import & Export wizard to work. It should work. Why doesn't it know what "time" is? I even checked the MSSQLToSSIS10.XML mapping file the wizard is using. This is what it has for "time":
I need help for SSIS Pacakge. using condtional Split How to insert One records with Multiple time depending on Source column value .Is there possible to wrtie the condition in Conditional split.
For Exmaple :
Source Table Name : tbl_source
following Column Name: col_Name1,Col_Name2,Col_Name3, col_Id,Col_Descrip
table contain only one records:GRD1,SRD1,FRD1,100,Product
I want Insert the Destiantion table the Follwing Condition. using Conditional Split.
1)Cond1 (!(ISNULL(GRD1))
2)Cond2 !(ISNULL(SRD1))
3)Cond3 !(ISNULL(FRD1))
I need the Following output
Destination Table Name : tbl _Dest(for One record in source table i need following records in destination)
Coulmn Name , Column Value , ID
Row 1 GRD GRD1 100
Row 2 SRD SRD1 100
Row 3 FRD FRD1 100
How to achieve this result. can u anyone help me.using Conditional split iam getting only first condition Result.
