I am trying to change the type of a column from varchar(2000) to varchar(max). This results in a "row size (8090) exceeds the maximum number of bytes per row (8060)." error, which makes no sense to me. I am on SQL server 2005.
Kindda solved. Initially we could not use the designer to alter the column (timeout issue), and altered the table manually, which failed. Finally we tried copying the designer-generated scripts and running them manually (thereby bypassing the timeout). Success. Still makes no sense though, but now it works :o)

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.
After rebooting SQL Server 2005 Standard 9.0.3233, we have been experiencing the above error in some of our stored procedures which try to insert into a table variable from a specific column of a table. The base table has the column defined as varchar(10), but the table variable has the column being inserted into defined only as varchar(3). However, the SELECT statement only returns data with 3 or less characters.
We have not changed the data or the code base in any other way, and this is only happening on our production server. If I run the same query on a test server with the same SQL Server 2005 edition installed, but an older backup, the error does not occur. The same data is returned in both queries if the INSERT is removed, or the table variable column is extended to match the base table.
What I have noticed is that the execution plan is different when the same query is run on the two servers. On the server where the query works, there is a computed scalar operation which takes the column and does an implicit conversion to varchar(3), before it is then outputted to the nested loop join operation.
On the server that returns an error, there is a hash join and table scan of the base table instead. I have already tried to rebuild indices and update statistics on all tables involved, including using fullscan, and with the same stat_stream as in the server that works, but I can't get the same plan back.
For now we have fixed the few stored procedures which were broken by modifying the size of the table variable column, but I would like to know if there is a way to get the statistics and indices back so that they produce the same plans as before, in case there is more code out there which just hasn't executed yet.
This is known behavior and probably has nothing to do with your reboot. Effectively what's happening is that the optimizer is re-ordering the logical elements of your query for performance reason, but this is resulting in the truncation-error check being done before the WHERE clause's filtering.
The recommended solution is to wrap the column expression that gets assigned to your VARCHAR(3) in a CASE.. that duplicates the length test in your WHERE clause. I know that sounds illogical, but it usually fixes the problem.
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.
Im using Microsoft SQL Server Management Studio Express to connect to our SQL Server 2005 (think its 2005, its version 9.000 something something). I have a table with one column that saves a lot of text. I have set the column type to text. When i have a row with lots of text in this column i cannot delete it. I get the message "string or binary data would be truncated" when i try to delete it. If i try to edit the row i get the same message. What do i do?
Considerable : i fix it by drop table and create it again, but i wanna a Solution!
Though I'm late to the party, when I review the original poster's description of the problem, it sounds like they are trying to delete the row from within the table editor interface. I just encountered this same issue with a table containing a "text" column with long text, and it appears that the issue may in fact be tied to a limitation in the editor itself. From my own investigation, it appears that you will not be able to edit a row in which a text column exceeds 4000 characters. I tested with SSMS 2008 R2.
Hopefully this will help anyone else encountering this error.
I had same problem and solved ...
after selecting top 200 row of your table, click the "Show Criteria Pane"(left side of toolbar)
now uncheck your ntext column (the column holding a big text you was talking about)
now you can delete or update any row :)
Normally this kind of error happens when you're inserting a long value into the column that can't store it. Check whether you don't have any triggers or any related logic that could do that on your behalf when you're deleting the row (e.g. for logging purposes / audit trail)
I changed my data type to nvarchar(MAX) and was able to edit and delete as I saw fit.
I discovered there was a trigger that audited changes to the record (thanks Tomas Vana), but the target audit record had a limited varchar field for the action report (varchar(1000)). It was trying to audit the deletion of records that had varchar(max) fields...duh!
I changed the action report field in the log to varchar(max) and that fixed it...
bloody obvious really...:)
I am getting a "SQL Server Error: arithmetic exception, numeric overflow, or string truncation" error
here is the code below
AQuery:= TSQLQuery.Create(nil);
with AQuery do
begin
SQLConnection:- AConnection;
SQL.Text:= 'Insert into.....';
ParamByName('...').asString:= 'PCT';
.
.
.
try
ExecSQL;
finally
AQuery.Free;
end;
end;
I have alot of ParamByName lines, and I can't figure out which one is throwing the exception. I just know its thrown on the ExecSQL line. How can i tell which paramByName is causing the error?
When you have the metadata of the table, check the maximum length of string fields. When debugging, check the length of the strings you feed the parambynames. Also check the type of numeric fields, and make sure you don't exceed a maximum value. (I had this problem once with a string which length exceeded the varchars length in the table, and had this problem with a smallint databasefield that I tried to set to a too high value)
Get the SQL text after param substitution and run it as a query in SQL Server management studio.
You'll be able to debug it from there.
You are trying to insert a string value into a field that is not big enough to hold the value. Check the length of the values you are inserting against the length of the field in the table.
As others have said, it's almost certainly that you are pushing too-large a string into one of your fields. It could also happen with numeric values but it's most likely to be a string.
I'd suggest you temporarily alter each of your ParamByName('').AsString:=blah lines with a text constant, eg;
ParamByName('surname').AsString:='Smith';
ParamByName('firstname').AsString:='John';
etc, and see if you get an error. If it goes through without an error, then your problem is most likely to be that one of your string parameters is too long. Check your table schema and debug the actual strings you are putting into the parameters.
Depending on how much access (and experience) you have with this, you might find it more helpful to turn on the SQL Server logging such that you can see your queries (and the contents of those parameters) when the get processed by the SQL server. This will show you exactly what string and numeric values are actually being given to the server.
Which version/edition of SQL Server are you using?
