I'm trying to fetch data (source) from SQL server to create a text file in ADLS (Sink), but I'm facing conversion overflow error. which I found out is with this value (999999999.00000000000000000000). can someone help me on this.
I used Cast function in SQL server to make it an integer value & it did work, but I want to load the values as they are in the source without changing their type. Actually I want to load multiple tables at once.
Screen shot is also attached with. Thanks
I tried to reproduce your scenario in my environment, and I got similar kind of conversion overflow error.
The cause of error may be ADF is unable to handle the decimal values where Precision > 28 to resolve this the work around is, if possible, make your Precision <=28
When I reduced the Precision value from 30 to 28 for my column with decimal datatype it worked.
pipeline worked successfully.

I am running a jdbc query and using the result set to retrieve column values.
My output goal is a csv.
I am using Jython scripting in Maximo via the automation scripts.
I notice that I frequently get errors writing lines out and in the middle of output I get missing or truncated values from the point of error.
The errors read basically:
BMXAA7837E - An error occured that prevented the BIALOCHIERREP script for the BIALOCHIERREP launch point from running.
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 16: ordinal not in range(128) in at line number 224
psdi.util.MXApplicationException: BMXAA7837E - An error occured that prevented the BIALOCHIERREP script for the BIALOCHIERREP launch point from running.
It seems logical that some data coming in from the database is not UTF-8 if I am seeing this error
I know that other processes such as BIRT are able to read this very same data and get by the 'errors'
So is there a recommended way of getting by this or determining for sure whether the data is good or bad in the source database? I am currently somewhat immersed in trying to find the bad data using debug statements.
Since you are running SQL directly against the database, I would check whether your database has cast() or convert() functions you can call to do that conversion to ascii for you.
I have five or six OLE DB Sources with a String[DT_STR], with a length of 500 and 1252 (Latin) as Code Page.
The format of the column is like 0,08 or 0,10 etc etc. As you can see, it is separated with a comma.
All of them are equal except one of them. In this one source, I have a POINT as separation. On this it is working when I set the Data Type in the advanced editor of the OLE DB Source. On another (with comma separated) it is also working, if I set the Data Type in the advanced editor of the OLE DB Source. BUT the weird thing is, that it isn't working with the other sources although they are the same (sperated with comma).
I tested Numeric(18,2) and decimal(2).
Another try to solve the problem with the conversion task and/or the derived column task, failed.
I'm using SQL Server 2008 R2
Slowly, I think SSIS is fooling me :)
Has anyone an idea?
/// EDIT
Here a two screens:

Isn't working:

I would not set the Data Type in the Advanced Editor of the OLE DB Source. I would convert the data in the SQL Code of the OLE DB Source, or in a Script Transformation e.g. using Decimal.TryParse , which would update a new column.
SSIS is unbeleivably fussy over datatypes and trying to mess with its internals is not productive.
Check that there are any spaces in between the commas, so that the SSIS is throwing an error trying to convert the blank space to a number. A blank space does not equal nothing in between spaces.
Redirect error rows and output the data to a file. Then you can examine the data that is being rejected by the SSIS and determine why it's causing error.
Reason for the error
1) Null’s are not properly handled either in the destination database or during SSIS package creation. It is quite possible that the source contains a null database but the destination is not accepting the NULL data leading to build generate above error.
2) Data types between source and destination does not match. For example, source column has varchar data and destination column have an int data type. This can easily generate above error. There are certain kind of datatypes which will automatically convert to another data type and will not generate the error but there are for incompatible datatypes which will generate The value could not be converted because of a potential loss of data. error.
The Issue arises when there is unhandled space or null. I have worked around using the Conditional (Ternary) Operator which checks the length:
LEN(TRIM([Column Name])) >= 1 ? (DT_NUMERIC,38,8)[Column Name] : 0
I recently updated an SSIS package that had been working fine and now I receive the following error:
Text was truncated or one or more characters had no match in the target code page.
The package effectively transferred data from tables in one database to a table in another database on another server. The update I made was to add another column to the transfer. The column is Char(10) in length and it is the same length on both the source and destination server. Before the data is transferred it Char(10) there as well. I've seen people reporting this error in blog posts as well as on Stack, none of what I have read has helped. One solution I read about involved using a data conversion to explicitly change the offending column, this did not help (or I misapplied the fix).
whihc version of SQl Server and SSIS are you usign?
I would say to take a look at the output and imput fields of your components. CHAR always ocupies all it's length (I mean, char(10) will always use 10 bytes) and since you are having a truncation error, it may be a start. try to increase the size of the field or cast as varchar on the query that loads the data (not as a permanet solution, just to try to isolate the problem)
Which connection you are using ADO.Net or OLEDB connection ??
Try deleting the source and destination if there are not much of changes you have to make ..Sometime the metadata cuases this problems. If this doesn't solve your problem post the screen shot of error.
I have an SSIS package. The source is a SQL query. The destination is a table. The package worked until I changed a column in a destination table from datetime to datetimeoffset(0).
Now, all records fail with a "Conversion failed because the data value overflowed the type used by the provider" error on this particular column.
The value in the source query is getdate(). I tried TODATETIMEOFFSET(getdate(),'-05:00') without success.
In fact, the only thing that has worked so far is to hard code the following into the source query:
cast('3/14/12' as datetime)
The only other interesting piece of information is that the package worked fine when running the source query against another server implying that maybe a setting is involved - but I see no obvious differences between the two servers.
I was going to suggest to add a "data conversion component" to deal with it, but since you changed only on the destination, it means that you can change your source query to do:
select cast(YOUR_DATE_COLUMN as datetimeoffset(0))
In case anyone else is looking, we found an alternative solution that works if the source is in SQL 2005 (no support for datetimeoffset).
select dateAdd(minute,datediff(minute,0,getutcdate()),0)
The intent is to reduce the precision. Granted I also lose seconds but if I try the above line with seconds I get an overflow error.
I started using the system with a pre-made file called DB2.SQL. I am using this because it is what the tutorial said to use. I then edited this file and replaced the contents with my own code:
CREATE DATABASE BANKDB13 BUFFERPOOL BP0;
When I try to execute a SQL it though, I get this error:
DSNE377A INPUT DATA SET RECFM MUST BE F OR FB WTIH LRECL 80
What does this error mean and how do I correct it on the file?
I am running it with Vista TN3270 on Windows 7 over TSO, in SPUFI mode.
What I've tried so far:
When I start editing the file, I have a screen to change the defualts, and I have changed the RECORD FORMAT to F and FB as well as setting the RECORD LENGTH to 80 with no success.
EDIT:
I resolved the problem by deleting the DB2.SQL file and recreating it, and also making sure that the sizes I gave for the files were consistent with each other.
What SQL are you trying to execute on it?
The error means that the Record Format in the input data set must be either "F IXED" or "F IXED B" LOCK with a logical record length of 80.
So this is what the error means, how to correct it depends on the SQL you're running and the desired outcome.
What Tutorial is it that you refer to, do you have a link? Is this a real world problem, homework or you expanding your knowledge into mainframe DB2?
Your SQL snippet above is creating a DB, what is the INPUT DATASET file format that you are subsequently running SQL on?
