A data reader is using a connection manager to connect to an ODBC System DSN . A query in the SqlCommand property is provided. Data is being truncated in the only string column . The data type in data reader output-->external columns shows as Unicode string [DT_WSTR] Length 7.
The truncated output in a text file is the first 3 characters from left to right . Changing the column order has no effect.
A linked server was created in SQL Server Management Studio to test the ODBC System DSN using the following:
Data returned using "OPENQUERY" does not truncate the string column indicating that the ODBC Driver returns data as expected with sql 2005, but not with the Data Reader.
I have a data file that has numeric data that looks like:
1.123456
And this column is defined as a DT_NUMERIC(18.6) in the flat file conn mgr.
As an experiment, I changed the destination column to a NUMERIC(18,0) - hoping that this would throw a truncation error at the flat file task level (where I have Truncation on all columns set to "fail component").
Not a peep. It loaded the data into the table, chopping off the 6 digits after the decimal point.
You would THINK that this would cause an error, but no. Why is this? The flat file task complains about all kinds of things, but this is such a gross error, you would think it would catch it!
I'm working with some long standing VB/SQL Server applications and forthe second time we've suffered from having the parameters to a storedprocedure call get silently truncated now that the data field has gotmuch larger than when the code was developed all those years ago. Thisis always very hard to debug and I'd really like SQL Server to throwan error when this happens.I don't feel confident enablying the full ANSI_WARNINGS as it islikely to affect lots of functionality in the database inunanticipated ways.What I'd like to be able to do is enable only the ANSI check for thestring data getting truncated but haven't been able to find a way todo this. Is it possible?CheersDave

Hello, I am trying to store pictures in an Image data type column of my MsSQL table from PHP, or even SQL Query Analyzer for that matter. In PHP I use the bin2hex() function to get the HEX equivilent of the picture, I'm sure everyone knows that when you convert a Binary file to HEX, the file size is doubled. When I try to insert the HEX file into my table with a query like: INSERT INTO PicTable (fileType, fileData) VALUES ('jpg', 0x47494638396164014100f70000000000ffffff2f2f2fe800020c0c0ce....)
MsSQL will store EXACTLY HALF of the file. The byte count of the stored HEX data and original Binary data is exactly the same, so when I try to extract the file and display it, in a browser window for instance, I can see exactly half of the image. I have tried everything I can think of to fix this, but I am at a loss. Does anyone know of anything that would cause this strange behavior. I have no problems at all doing this with MySQL's BLOB data type. Thanks in advance for any help.
The length of the longest polygon coordinates record is about 115,000 characters. I believe the varbinary(MAX) type should hold that data, but SQL throws a truncation error every time I try to import the data.
I'm reading data from a flat file source. If some data gets truncated, i have the option of 'ignoring', 'redirecting' or 'fail component'.
What i'd like to do is, to allow the data to be truncated, but i'd also like to write a log entry so that i can know that a particular rows data has been truncated.
I've tried 'redirecting' the row to a script component (as transformation), but i don't know how to determine if the error is truncation or not, not only that, i can't redirect the row back to the 'original' flow, which is a derived field column.
In my case, I have a column in a pipeline that is DT_STR with a length of 20. I'm trying to insert data from the data flow into a table (via an OLEDB destination) in which the destination column is varchar(50). When I review the metadata throughout the data flow, everything looks correct. However, I get a truncation warning stating that data loss might occur when inserting data into the string column of length 20 from a source column of length 50. Thus, it looks like the data flow is swapping the metadata for the source and destination columns when validating the data flow (and thus, producting the warning).
This is a pretty complex data flow, so I'd rather not have to rebuild it. And changing the metadata of the source column to be DT_STR with a length of 50 is going to wreak minor havoc in the data flow (as lots of things use that column).
Has anyone seen anything similar to this? The post referenced above deals with a package that is constructed programmatically, but the package I'm working with was created the old fashioned way...
"Bulk insert data conversion error (truncation) for row 1, column 1 (id)."
when you get the error above or similar in sql server 2000 does it continue inserting the data by truncating it or does it stop beacause looking at the data that i have got it seems to continue inserting the data but just truncates the colunm. i have tried it several time its seeems to be consistent.
I have data that has white spaces after the actual data e.g. '00093 ' hence i am happy aslong as i can be sure that it does always continue as i will be loading alot of data using a similar process.
hence my question is that will it load all the data all the time and just truncate it to fit the column size?
[Production IDW [1]] Warning: Truncation may occur due to retrieving data from database column "Industry" with a length of 16 to data flow column "Industry" with a length of 8.
When I look at the industry lookup table the column size is 50. But the data flow metatdata is saying the oclumn is 8. How can I change the data flow column? When I try to edit it and click on metadata it is uneditable. The field it is matching to is 50 and the field it is coming from is 16.
Is there a switch I can use to force a bulk insert and if data is truncated, I'm good with that. The truncated data, in this case, is not data I can use anyway if it is long enough to be truncated.
I need to keep the field at VARCHAR(23) and if I expand it, I won't be able to join on it after the file load completes. I'd like the data to be inserted (truncated if need be) and then I'll deal with the records that are truncated after I load the file.
I need to export some data from sql server 2012 to a excel file(.xlsx). Truncation error happened when executing the exporting task, error happened in conversion from a column of type nvarchar(max) to a column of type LongText. Max length of the source column data is 4303, and documented length limit of LongText, which is a alias of type Memo, is 64,000. why this error happen?

I am trying to insert a row into a table of Microsoft SQL Server 2000.
There are various columns.
[SNO] [numeric](3, 0) NOT NULL , [DATT] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [DATTA] [char] (3000) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [CODECS] [char] (32) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
The [DATTA] column is causing a problem. Even if I am trying to put only 1700 character string into [DATTA], the java code throws the following exception:-

Why is it throwing an exception even though the sum-total of this row doesn't exceed 8000 characters?
Hello, I am tring to add a string my database. Info is added, but it is the name of the string, not the data contained within. What am I doing wrong? The text "Company" and "currentUserID" is showing up in my database, but I need the info contained within the string. All help is appreciated!

This one has bothered me ever since sql server 2000.
When you do an insert into a table with literally hundreds of char or varchar columns and you get the error that the insert failed due to data loss/truncation on a column.
Is there anyway in 2005 to actually find out what column ? Since there are hundreds is is literally a long process of going though each column 1 by 1 manually.
The database engine surely MUST know what column this occurred on so why can it not tell you which column the truncation occurred on ?
Can this be done in 2005 if not will this information be available in 2008 ?
When I enter over 4000 chars in any ntext field in my SQL Server 2005 database (directly in the database and through the application) I get an error saying that the data could not be updated because string or binary data would be truncated.Has anyone ever seen this? I cannot figure out what is causing it, ntext should be able to hold a lot more data that this...
"pRecordSet" is an ADO recordset. The database column "MyColumn" is of type "decimal(19,10)".
The most important question for me is, if the regional settings of the database server or the regional settings of the client PC are considered during the conversion from the string to the decimal value. For example in standard French regional settings the "." would not be recognized as decimal separator.
I am also wondering if the language of the database instance, in which this data is saved, is considered during this conversion or any other settings of this database instance.
So my general question is: Does anybody know exactly what rules apply during the above mentioned conversion?
i want to import data from an excel sheet into a database. While reading from the excel sheet OleDb automatically guesses the Datatype of each column. My Problem is the first A Column which contains ~240 Lines. 210 Lines are Numbers, the latter 30 do contain strings. When i use this code:
Code BlockDim sConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & conf_path_current & file_to_import & ";Extended Properties=""Excel 8.0;HDR=NO""" Dim oConn As New OleDb.OleDbConnection(sConn) Dim cmd1 As New System.Data.OleDb.OleDbCommand("Select * From [Table$]", oConn) Dim rdr As OleDb.OleDbDataReader = cmd1.ExecuteReader Do While rdr.Read() Console.WriteLine(rdr.Item(0)) 'or rdr(0).ToString Next
it will continue to read the stuff till the String-Lines are coming. when using Item(0), it just crashes for trying to convert a DBNull to a String, when using rdr(0).ToString() it just gives me no value.
So my question is how to tell OleDB that i want that column to be completly read as String/Varchar?
Thanks for Reading

I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A: (name phone house cost of house,zipcodecountystatecountry) -a view will later split this large varchar string based column b: is the source filename of the data load (varchar 256) ....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?
When using AquaData or JDBC (inet tds driver), when doing an insert using SqlServer 2005, I get error "String or binary data would be truncated" when the data is actually OK. There are no triggers, etc. that would confuse the situation. It works fine in SqlServer 2000.
Create and populate table: create table maxtable ( tablename varchar (18) not null, [...] )
Try to insert into test3: insert into test3 (name, tbname) select i.name, o.name from dbo.sysindexes i, sysobjects o, maxtable m where i.indid > 0 and i.indid < 255 and i.id = o.id and i.indid = 1 and o.name = lower(m.tablename)
And I get the error "String or binary data would be truncated." The values being selected for i.name and o.name have maximum length of 18. There are other rows in sysindexes and sysobjects with longer values, but they are not being selected.
The error does not occur with SQL Server Management Studio, and does not occur using SqlServer 2000.
Hi! Need help with this one: I have a column with a string composed by several data. After using REPLACE several times, I get something like the data below, which has (in most of cases) a value and a date.
378 9/05
388 9/05
4/05
1/06 606
1/06 646
76 5/05
100 1/05
118 8/05
129 8/05
9/05 342
05/3 123
1/07
4/06 164 The problem is that I need to get each value alone (to separate columns), in example: Value Date 378 09/2005 388 09/2005 0 04/2005 ... 606 01/2006
and so on... In addittion you can see that sometimes the Value come first or alone, and sometimes the Date come first or alone.
I will appreciate any good ideas, Thanks in advance, Aldo.
If you are running in Full Recovery Mode and do a full backup every night but never do a backup of the log during the day does the log file ever truncate? From what I read this should be in Simple Recovery Mode but I'm wondering what happens in the case that I mention in the first sentence. Thanks.
As you can see in Table 1, if a CustomerID has only one StaffID associated to it, the "Percentage" Column's value is 1. In the cases where there is more than one StaffID associated to a particular CustomerID, the percentage column get's split up among the StaffIDs, however the sum of this split can never exceed 1 (100%) per CustomerID.
I need to know how to find the cases where there is more than one StaffID associated to a CustomerID, group the CustomerIDs, and build a string made up with the StaffID and Percentages as shown in Table 2.
Any help would be greatly appreciated, as I've struggled with this one for a while and have hit a brick wall.
Hello Everyone and thanks for your help in advance. I am working on importing a flat text file into SQL Server 2005 and am having problems. The flat file is a CSV text file with " being used as a text qualifier. Each line is broken by a CrLf combination. When I try importing this file into a SQL Server 2000 table using the same datatypes and sizes for each column, it works perfectly fine with the data importing as expected. However, in SQL Server 2005, again using the identical column datatypes and sizes, the import fails giving me warnings such as: * Warning 0x802092a7: Data Flow Task: Truncation may occur due to inserting data from data flow column "Column 0" with a length of 50 to database column "MLS_ID" with a length of 10. (SQL Server Import and Export Wizard) Virtually every columns gives this type of warning, yet I don't understand why since the columns are all variable in length (every message says a column length of 50) and all are delimited rather than fixed size. Then later in the import, errors occur something like: * Error 0xc02020a1: Data Flow Task: Data conversion failed. The data conversion for column "Column 15" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.". (SQL Server Import and Export Wizard) * Error 0xc020902a: Data Flow Task: The "output column "Column 15" (70)" failed because truncation occurred, and the truncation row disposition on "output column "Column 15" (70)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component. (SQL Server Import and Export Wizard) I haven't got a clue as to why this is happening. For the record, on the flat file source screen, I have ensured that delimited has been selected rather than fixed width. Any help on this issue owuld be greatly appreciated. Thanks.
Could someone please let me know what are the exact steps to follow to truncate the transaction log files? As these log files grow very fast and there seems to be no space in the drive.
Currently am using the below steps to truncate the log file: Step1:Use the below syntax: backup log <database name> with no_log Step2:shrink the log file. Right click the correct database and choose shrink file ->chosse the log -> ok
I would be grateful if someone can give me a proper solution.
Hello All,I am attempting a bulk load of fixed position flat file data via bcpand I have noticed that I get a Right Truncation error when trying toload a row where the last column value is NULL.For example:Flat file row:0000016MFMT file:7.031 SQLCHAR 0 7 "" 1 RECORD_KEY2 SQLCHAR 0 1 "" 2 SEX3 SQLCHAR 0 1 " " 3 HEIGHTIn this row, the height info is null and I get a right truncationerror. The row below, with height info goes in fine:Flat file row:0000016M510Let me know what I am doing wrong!Thanks in advance
How is it possible to avoid truncation errors in MS SQL? For example,if I run the followingdeclare @a as decimal(38,8)declare @b as decimal(38,8)declare @c as decimal(38,8)set @a = 30.0set @b = 350.0set @c = @a/@bselect @cset @c = @c*@bselect @cI get 29.99990000 instead of 30.0. Is there a way around this?ThanksBruno
