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 have been searching for a solution to this and haven't had any luck.
I have an SSIS package which is loading data from one table and after some lookups, etc. writes it out to another table.
The above error is occurring during the first step of the Data Flow which is an OLEDB Source (SQL 2016 db).
The column in question is an nvarchar(250) and there is nothing that changes it to an int at any point.
I'm thinking that it must be some sort of implicit conversion, but why when it is nvarchar all the way through?
I'm pulling my hair out with this, does anyone have any ideas please?
Thanks for the responses.
The issue seems to have been a buffer size issue with with a lookup task.
When I checked the lookup table, it didn't have an appropriate index. I have added one and it seems to have solved the issue.
Sometimes SSIS keep the old metadata with the auto-convert.
I suggest that you delete your ole Db source component and rebuild a new with your select. Moreover you can go to advenced option (right click on the source component and in the last tab you can validate the datatype of your column and adapt to varchar if it is integer.
I have two packages that I built in SSIS. This package goes out to a file path, pulls in two excel files, and loads them to two tables in SQL Server db. One of the packages runs fine and loads its respective table. However, the other excel/csv file contains two date columns and the package is failing because the SQL Server table that it needs to load to has two DateTime columns. The error I am getting is:
-There was an error with OLE DB Destination.Inputs[OLE DB Destination Input].Columns[CustDate] on OLE DB Destination.Inputs[OLE DB Destination Input].
I have tried to cast the datetime column to Date in the SQL table, and it still doesn't work and throws the same error. I have added a data conversion task in SSIS to try and convert the two date fields to multiple datatypes, and I still get an error. Can someone please tell me what datatype I should convert these two fields in the SSIS package where it would work? The first package runs fine because it doesn't contain any date fields in the excel file or the table it loads to.
So far, I have tried to convert these two date fields to: string[DT_STR], Unicode string[DT_WSTR], date[DT_DATE] and none of them work. Can anyone offer up any suggestions? Thank you!

Made the following 2 changes. It will give you answer.
1) Select your excel file connection and add IMEX=1 to the end of the connection under properties. So your connection string will now look like
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\SSIS\Test.xls;Extended Properties="EXCEL 8.0;HDR=YES;IMEX=1";
2) Use the following expression in the derived column transformation
ISNULL([CustDate]) ? NULL(DT_DATE) : (LEN(TRIM([CustDate])) == 0 ? NULL(DT_DATE) : (DT_DATE)((DT_DBDATE)TRIM([CustDate])))
I have migrated a Sybase database to SQL server 2008.
The main application that using the database trying to set some of dateTime2 column with data like 1986-12-24 16:56:57:81000 which is giving this error:
Conversion failed when converting date and/or time from character string.
Running the same query using dot(.) instead of colon(:) as millisecond separator like 1986-12-24 16:56:57.81000 or limiting the milliseconds to 3 digits like 1986-12-24 16:56:57:810 will solve the problem.
NOTE:
1- I don't have access to the source of application to fix this issue and there are lots of table with the same problem.
2. Application connect to database using ODBC connection.
Is there any fast forwarding solution or should i write lots of triggers on all tables to fix it using the above solutions?
Thanks in advance
AS Gordon Linoff said
A trigger on the current table is not going to help because the type
conversion happens before the trigger is called. Think of how the
trigger works: the data is available in a "protorow".
But There is a simple answer!
Using SQL Server Native Client Connection instead of basic SQL Server ODBC connection handle everything.
Note:
1. As i used SQL Server 2008 version 10 of SQL server native client works fine but not the version 11 (it's for SQL Server 2012).
2. Use Regional Settings make some other conversion problem so don't use it if you don't need it.
Select REPLACE(getdate(), ':', '.')
But it will Give String Formate to datetime Which is not covert into DateTime formate
Why would you need triggers? You can use update to change the last ':' to '.':
update t
set col = stuff(col, 20, 1, '.');
You also mistakenly describe the column as datetime2. That uses an internal date/time format. Your column is clearly a string.
EDIT:
I think I misinterpreted the question (assuming the data is already in a table). Bring the data into staging tables and do the conversion in another step.
A trigger on the current table is not going to help because the type conversion happens before the trigger is called. Think of how the trigger works: the data is available in a "protorow".
You could get a trigger to work by creating views and building a trigger on a view, but that is even worse. Perhaps the simplest solution would be:
Change the name and data type of the column so it contains a string.
Add a computed column that converts the value to datetime2.
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:

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.
