SSIS Tries To Insert NULL Value Into A Destination Column Ignored In The Mapping.
Jan 12, 2008
Hello everyone,
I am having a little problem with a simple package and I do not know if this is a known issue or that I am missing something.
I have a data flow task, a simple one, with an oledb source pulling data, using a select statement, from a sql server 2005 instance, and an ole db destination pointing to a table in a sql server 2000 instance. Both intances are standard edition. The table in the destination has a column which allow null values and has also a default constraint (getdate()), and this column is not present in the source. When I map the columns in the destination, I leave this column as "ignore", not being mapped to any column from the source. The problem is that when I execute the task, SSIS is trying to insert NULL value into this column, so the package fail with the error "can not insert NULL value into column myColumn". I wonder why is it trying to insert NULL value if the column is not mapped to any column from the source.
Is this a known issue or I am nissing something in the settings?
If the destination table has rowversion or identity columns, there is no problem ar all. I ignore those columns in the mapping and SQL Server feeds them as expected.
I have created a package which transfers data from a SQL server source to an Excel Destination. The DataFlow Task works fine , if i pre-define the column names in the Excel Destination... But i run into an error when i give the blank excel sheet as my destination. I am unable to map any columns
A sample example is as shown above .. In the column mappings field only one column in the Excel shows up for mapping and eventually throws the error "[Excel Destination [42]] Error: The number of columns is incorrect. "
How do we proceed in this case , where in we do not want to give pre-defined coulmn names in the Excel Destination sheet.
After: If (Row.RegenerateXML_IsNull()) Then Command.Parameters.AddWithValue("@RegenerateXML",System.DBNull.Value) Else Command.Parameters.AddWithValue("@RegenerateXML", Row.RegenerateXML) End If
Which is great but it does turn 1 line into 5 lines. I have 20 parameters which takes up 20 lines of code which will now be 20 x 5 = 100 lines of code.
My question is :
Is there a better way to write this code without having to take up so many lines?
The only way to add a new column to an existing mapping that I know is to go to advanced editor and refresh. This however keeps only the default mapping (where the field names match), the rest is wiped out, so need to restore the mapping manually after that. Risky and annoying at the same time. Is there any alternative?
I am transferring a huge Database running on PostgreSQL to SQL SERVER using SSIS. I have already mapped all the columns between source and target tables. Is it possible in SSIS to get a graphical diagram showing all the source and targets tables and its mapping?
I have a condition where if column5 is equal to 1 then put column6 into the destination column "dest6", if it is not equal to 1 then put column6 in destination column "dest7"
What is the best way to do this in SSIS?
If I have to use the conditional split then do I have to copy my complete mappings, exact change this one column?
Thank for the help this mapping will take me a long time!
In my destination table i am having some 30 columns and the CSV files what i get may have 10 columns or 20. How do I map columns between source and destination dynamically?
Hi, I was wondering how I can complete a column (which doesnt have an input one) with data. For example:
I have a sql query which bring data of 3 columns
ID | FISRT NAME | LAST NAME 1 MIKE MORGAN 2 SARA JOHANES
So, I will insert that data in a FLAT FILE CONNECTION MANAGER, which I configured with 3 columns and I did the corresponding mapping in the FLAT FILE DESTINTATION.
Now, If I add one more column in the FLAT FILE CONNECTION MANAGER, I will not have it mapped to a input one, obviously. So, what I need is to add one more column to the flat file destination and complete it with zeros values in it.
Probably I can solve this part by introducing a DERIVED COLUMN and there I can configure the zeros that I want to add to the column. But I'm not sure if I can do that without having a input column. So, the question will be, how can I add one column to a flat file which doesnt have a input and introduce any value that I want to it? Hope I was clear Thanks for your help.
SampleID  Rep_Number  Product  Protein  Fat  Solids
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
I have some source files is there today it will have 4 columns..Tomorrow it will have 10 columns...my package is dynamically load the data to destination table..How we have do it in Using script task...
I am copying a simple table from a Sql Server 2005 database to an *.sdf mobile database.
I am brand new to SSIS and I am probably doing something wrong. But after executing the SSIS package all the rows and all the fields are NULL in the destination database. I put a datagrid viewer between the OLE DB Source and the Sql Server compact edition destination and I can see the real data which is obviously not ALL NULL.
Does anyone have a clue as to why it would be doing this?
I have a small problem in parameter mapping for Execute SQL Task. I am using a delete statement with 2 conditions. Followed by another Execute SQL Task which contains commit statement.
delete from tname where c1 = ? and c2 =?
where c1 is number(4) datatype and c2 is of varchar2(20) datatype in oracle.
The connection manager i am using is ORacle OLE DB provider. I am passing 2 global variables i.e g_v1 of Int32 and g_v2 of String Type.
In the parameter mapping of the Executing SQL task, i am mapping these 2 variables for c1 and c2 and changed the datatypes inside parameter mapping as Numeric for c1 and Varchar for c2.
I also set the property as ByPassPrepare = True.
When i am executing the package i getting INVALID NUMBER ERROR. i believe the SSIS is unable to perform the implict datatype converison.
For the next run, i changed the g_v1 varible datatype to Double and also i changed the parameter mapping for c1 as Doble datatype. This time it is working fine. I can see the Green signal for the 2 SQL Tasks.
But when i connected to Oracle check the count in the table, the data is not getting deleted.
Also, I set the property RetainSameConnection = TRUE for oracle connection manager. I am not able to trace this logical error.
The same is working fine in my local machine. But i am facing the problem when i deployed the same on the client machine.
Is there any problem with parameter mapping? What should be equialent Datatype for Oracle NUMBER datatype that should be used inside the SSIS package while declaring the global variable and inside the parameter mapping.
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

I am trying to migrate database from old structure to new structure usign SSIS.
The table in new db have extra field that i need to assign it using variable. this is because i have few customer that having different variable value. (meaning for 1 customer, the variable will be fix for all the tables in the database)
my question, without using the Execute Sql Task, can i assign the variable into the the old db destination?
eg my data flow Task is : OLE Db Source - Derived Column - OLE DB Destination.
Example data
Old structure (key = txnID) --------------------- TxnID ChequeNo Bank (chq Bank - Bank in Bank) Amount
I receive this message when I try to run any report. The reportserver and reportservertempdb databases were upgraded using backup/restore from SQL2000 to SQL2005 on a separate server which is running RS2005 . Please help. Thanks
Hello, What I'm trying to accomplish is to have a variable names "SourceTable" and "DestinationTable". So for each SourceTable, the DestinationTable will have the same columns. All I need is to auto-map these columns between source and destination via code?
As soon as I call the input.GetVirtualInput(); method I get a com exception ,Seem that I am missing a
VirtualInputColumnCollection on the component ,but can't seem to figure out why.
When I drop the all the other components and only keep the OLEDb Source and OLEDB Destination with a flow between them , the call to input.GetVirtualInput() doe not fail with a com exception and I can mapping normally
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?
I am using SSIS integration between two database. Both databases are sql server 2008. Â using many integration but getting problem in two only only two integration giving problem, both are executing perfectly and out put also not showing any error.
but destination table not inserted/updated anything.
first issue integration is using data flow task with oledb source and destination. second one is using execute task with for-eachloop container.
What I want to do, is save a NULL value in the Customers.LevelId when no level is selected. I'm using C#, a CLR StoredProcedure and the DbType.Int32 for that column. When I try to save a null value, it says "cannot convert null to int", what is clear. But in the database it is possible to save a NULL value.
The question is: How to save a null value in a int column via a C# CLR Stored Procedure?
"Cannot insert the value NULL into column 'ID_Month', table 'Database_DW.dbo.Incident_Summary'; column does not allow nulls..."
At my table, I have a primary key which make autonumber for any record set in column 'ID_Month'. How can I insert autonumber in column 'ID_Month'by SQL statement?
I have a requirement to take xml file, in case the number of column changes, it should not fail the package, rather it should load the data in destination table. Destination table could be altered separately depending on xml schema by the DB team in production.
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.
Hello, I'm working on a website that allows users to upload small JPEG files. I followed the article at http://aspnet.4guysfromrolla.com/articles/120606-1.aspx. On the webpage I'm using a formview control to insert new records in the database. As suggested in the article I removed the "type='object'" from the insert parameters for the image column. The data is saved by using a sqldatasource with stored procedures. The image column is of type varbinary(max) and allows null values. Everythings works fine as long as the user uploads an image. The data is saved correctly and on another page the image can be viewed. However if the user does not upload a picture and tries to save the new record the following error is thrown: �Implicit conversion from data type nvarchar to varbinary(max) is not allowed. Use the CONVERT function to run this query.� In the formviews iteminserting event I have the following code: Dim imageBytes(fileupload1.PostedFile.InputStream.Length) As Byte fileupload1.PostedFile.InputStream.Read(imageBytes, 0, imageBytes.Length) e.Values("Image") = imageBytes What code should I use in case the fileupload1 has no file? I tried something like: e.values("Image") = dbnull.value But that doesn't work. Any suggestions?
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.
Cannot find an answer to this in previous posting, though there are similar topics.
My primary key "ID" requires a value (is not nullable), and not explictly providing it with one when I update a new record gives the following error:
Cannot insert the value NULL into column 'ID', table 'AdClub.mediaq.News'; column does not allow nulls. INSERT fails. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'ID', table 'AdClub.mediaq.News'; column does not allow nulls. INSERT fails.
However, trying to stuff that field with a recordCount+1 value (or any value), I get this error:
Violation of PRIMARY KEY constraint 'Primary Key'. Cannot insert duplicate key in object 'News'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'Primary Key'. Cannot insert duplicate key in object 'News'.
Cannot figure this one out. The value I'm providing for that field is known to be unique, but the SQL Server spits it out each time.
Is there a way to have the ID primary field automatically update with a new value when a new record is generated? This is how I used to do it in Access, but cannot find a similar feature in SQL Server. I'm sure I'm missing something simple, but right now I'm stuck in this "Catch-22" situation.
