I'm trying to resize a column down to 64 characters in length:
ALTER TABLE [dbo].[consumption]
ALTER COLUMN [resourceGroup] VARCHAR(64) NOT NULL
but I get the following error:
String or binary data would be truncated in table 'dbo.consumption', column 'resourceGroup'. Truncated value: ''.
This doesn't make sense to me: how can you truncate nothing?
Any help would be appreciated.
Thanks to comments by #MartinSmith and #DaleK, I think I've come to the answer on this one.
The documentation provided with the data source I'm writing to this column stated that it should not be longer than 64 characters. Then, when I tried changing the length of the column, the error message led me to believe that SQL Server was issuing an error over an empty string. According to #MartinSmith, this type of error message is a recent development and so the offending value probably hasn't been injected into it yet for ALTER TABLE commands. Moreover, queries against the column reveal that it does contain values longer than 64 characters.
Therefore, this error message should be taken at its meaning and the truncation value ignored.

I am attempting to do an insert from a select statement in SQL Server 2008 R2. The destination column's data type is char(7) and I have verified the len() and datalength() of the source column to be no longer than 6.
I am getting truncation error:
Msg 8152, Level 16, State 14, Line 219
String or binary data would be truncated.
I have verified using temp tables that an insert into a char(9) column works, but unfortunately the destination database will not support the data type change.
UPDATE: I was able to do the insert as required by adding a DISTINCT clause to the select statement in question, however the number of rows remains the same. So, I guess the reformatted question is why does adding the distinct clause return no error message even if the data is the same? Thanks!
What character set are you using? Some character sets have characters that take up two bytes. However the length function will still count them as 1.
I agree with Bill and David. But if most of the characters from your source are multi-byte then (some characters even take up 3 bytes) then you may need to use something like varchar(50) just to make sure your field is big enough to avoid truncation errors.
I have an ssis package created in vs 2005 that has started to give me the following error:
[Lawson Staging Table [4046]] Error: There was an error with input column "JOB_CODE" (4200) on input "OLE DB Destination Input" (4059). The column status returned was: "The value violated
the integrity constraints for the column.".
My first question is: what are the 4046, 4200 & 4059 values following my table, column and destination?
My second question is about the integrity constraint message. The destination table is a heap (no keys or indexes) with no constraints. The destination column is defined as a varchar(10). The input column is from oracle, is defined as char(9) and is called job_code. So - where is there an integrity constraint defined?
The final question is about the select statement; looks like the following:
Select ...
,lpad(trim(e.job_code),10,'0') as job_code ...
If I take the lpad and trim functions out, it works but I need these functions in place because my spec calls for a fixed length column padded with leading zeros. This column returns data as expected in TOAD but fails in the ssis package. Does anyone see an issue with how the functions are being used?
Since this package worked in the past but suddenly started to throw this error, I'm assuming that new invalid data has come into play. however, recently added rows don't seem to be any different then historical records.
Those numbers are more likely to be the ids assigned to the each task/table/column etc.
You could probably go to the advanced editor of the data flow task and look at the input and output properties. You can see that for each input or for each column there is an ID assigned.
Next: The error that you are getting occurs usually when "Allow Nulls" option is unchecked.
Try this:
Look at the name of the column for this error/warning.
Go to SSMS and find the table
Allow Nulls for that Column
Save the table
Rerun the SSIS
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.
We currently use the SQL Publishing Wizard to back up our database schemas and data, however we have some database tables with hashed passwords that contain the null character (chr(0)). When SQL Publishing Wizard generates the insert data scripts, the null character causes errors when we try and run the resulting SQL - it appears to ignore ALL TEXT after the first instance of this character in a script. We recently tried out RedGate SQL Compare, and found that it has the same issue with this character. I have confirmed it is ascii character code 0 by running the ascii() sql function against the offending record.
A sample of the error we are getting is:
Unclosed quotation mark after the character string '??`????{??0???
The fun part is, I can't really paste a sample Insert statement because of course everything that appears after the CHR(0) is being omitted when pasting!
Change the definition of the column to VARBINARY. The data you store in there doesn't seem to be an appropiate VARCHAR to start with.
This will ripple through the code that uses the column as you'll get a byte[] CLR tpe back in the client, and you should change your insert/update code accordingly. But after all, a passowrd hash is a byte[], not a string.
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?
