I have a source connection which is a ADO.NET MySql, I execute a stored procedure on MYSQL connection which gives me the data set, as we know SSIS tries to read the data from few rows and define the metadata when I run this procedure it defines the data based on data which it receives, however I run this procedure in loops for different sites (server and connection details are parameterized) columns and data types are same for all the sites, since SSIS reads only few columns while defining the metadata it doesn't get the data length and precision's correctly and they error out at the source connection itself, I am writing these errors to the flat file to process them later, when SSIS writes the error it replaces actual value with NULL.
For Example for column which is defined as Numeric(4,2) when it encounters the values such as 243.32 instead of writing the actual value to error file it writes a NULL value.
Is there anyway we can make SSIS write the actual value to the error file, Below is the Job Flow, Appreciate any inputs on how we can handle this,
Explained in the details of the problem
I've tried finding a solution for my issue but alas the problem continues. I've got an Excel Data Destination which I am trying to map in to SSIS [Please note I am saying the issue with the way SSIS identifies the Data Type of the Excel input. The scenario is OLE DB Source > Data Conversion > Excel Destination, please don't tell me to do a Data Conversion or use the Input and Output Properties method because it doesn't work, it just converts back to what SSIS "thinks" it's meant to be the instant I click out of the operations window]. I'm trying to create a new Excel Document through SSIS by mapping out the template to my data source from OLE DB Source.
Now when I do it with example data in the Excel Destination, it works fine because SSIS registers that the value in the workbook is a NTEXT [which is what I want]. However, the instant I apply the expression to use a blank template [with just headers no example data] it converts the Data Type in my Template to NVARCHAR(255) which is wrong and my package fails when I execute it, due to incompatible Data Type.
I've tried converting the Data Type within the Excel workbook to a TEXT format but it doesn't matter because when you pull it in to the Data Flow SSIS overwrites it and identifies that Column as a NVARCHAR(255). Even when I give up and comply and change the Input Data to NVARCHAR(255) because I'm just so annoyed, it still doesn't work because it fails my package and gives me an error message that it truncates my column field [-_-"]. I can't win.
I'll probably try and use a SQL Command to force it to identify the column as a NTEXT in the Excel Destination Editor or just rewrite some form of Forced SSIS to identify the Column as NTEXT but is there another way I am not aware of? I feel this is quite a known issue and there should be a plausible solution. Any assistance will be appreciated. Thank you.
I am running my mapping on blaze engine and my target hive table is transnational.
I have a field coming from source with data type as 32000 (varchar), but when I run the mapping , it is getting failed with following error.
"The Integration Service failed to execute grid mapping with following error [An internal exception occurred with message: The length of the data is larger than the precision of the column.]."
Any insights will be very helpful
Note: 1. My target is a hive table and it's transactional properties are true.
2. I am running this mapping on blaze informatica engine which needs update strategy to be used.
3. Target column field length is also varchar(32000)
Check that the length of the source data you are ingesting is not bigger that 3200 characters.
If you using a flat file as source check the delimiters and be sure that is reading correctly the file.
I'm trying to insert a large CSV file (several gigs) into SQL Server, but once I go through the Import Wizard and finally try to import the file I get the following error report:

I created the table to insert the file into first, and I set each column to hold varchar(MAX), so I don't understand how I can still have this truncation issue. What am I doing wrong?
In SQL Server Import and Export Wizard you can adjust the source data types in the Advanced tab (these become the data types of the output if creating a new table, but otherwise are just used for handling the source data).
The data types are annoyingly different than those in MS SQL, instead of VARCHAR(255) it's DT_STR and the output column width can be set to 255. For VARCHAR(MAX) it's DT_TEXT.
So, on the Data Source selection, in the Advanced tab, change the data type of any offending columns from DT_STR to DT_TEXT (You can select multiple columns and change them all at once).
This answer may not apply universally, but it fixed the occurrence of this error I was encountering when importing a small text file. The flat file provider was importing based on fixed 50-character text columns in the source, which was incorrect. No amount of remapping the destination columns affected the issue.
To solve the issue, in the "Choose a Data Source" for the flat-file provider, after selecting the file, a "Suggest Types.." button appears beneath the input column list. After hitting this button, even if no changes were made to the enusing dialog, the Flat File provider then re-queried the source .csv file and then correctly determined the lengths of the fields in the source file.
Once this was done, the import proceeded with no further issues.
I think its a bug, please apply the workaround and then try again: http://support.microsoft.com/kb/281517.
Also, go into Advanced tab, and confirm if Target columns length is Varchar(max).
The Advanced Editor did not resolve my issue, instead I was forced to edit dtsx-file through notepad (or your favorite text/xml editor) and manually replace values in attributes to
length="0" dataType="nText" (I'm using unicode)
Always make a backup of the dtsx-file before you edit in text/xml mode.
Running SQL Server 2008 R2
Goto Advanced tab----> data type of column---> Here change data type from DT_STR to DT_TEXT and column width 255. Now you can check it will work perfectly.
Issue:
The Jet OLE DB provider reads a registry key to determine how many rows are to be read to guess the type of the source column.
By default, the value for this key is 8. Hence, the provider scans the first 8 rows of the source data to determine the data types for the columns. If any field looks like text and the length of data is more than 255 characters, the column is typed as a memo field. So, if there is no data with a length greater than 255 characters in the first 8 rows of the source, Jet cannot accurately determine the nature of the data type.
As the first 8 row length of data in the exported sheet is less than 255 its considering the source length as VARCHAR(255) and unable to read data from the column having more length.
Fix:
The solution is just to sort the comment column in descending order.
In 2012 onwards we can update the values in Advance tab in the Import wizard.
i'm working on ssis package and i'm taking values from .xml file to ado .net destination
but when i enter values iinto table getting following error :
potential data loss may occur due to inserting data from input column "Copy of swaps_Id" with data type "DT_I8" to external column "swaps_id" with data type "DT_I4". If this is intended, an alternative way to do conversion is using a Data Conversion component before ADO NET destination component
I have used Data conversion transformation editor then also getting above error
what should be corrected?
This warning means that data in Copy of swaps_Id is 64bit integer and you trying to insert it into 32bit integer column in destination table. What should you do depends on your data.
If you are sure that data in your column is in 32bit signed integer range (-2^31 (-2,147,483,648) to 2^31-1 (2,147,483,647)) you can leave it as is (data truncation will never occur, bur warning will stay) or do data conversion or change Copy of swaps_Id column data type
If not, you should change column data type in your destination data table to 64bit integer (bigint in Sql Server)
This simply means that your source data type is Larger than what your destination can handle. On the Data Conversion Transformation, you may want to convert the column to DT_I8 datatype in order for that warning to disappear.
