I'm using a bit-wise comparison to effectively store multiple values in one column. However once the number of values increases it starts to become too big for a int data type.you also cannot perform a bitwise & on two binary datatypes. Is there a better way to store the binary data rather than int or binary?
View 9 RepliesFrom what I can see, the 'varbinary(max)' data type is not supported, and the 'image' data type is supposed to go away. Is there some other way to store large chunks (10MB to 100MB) of data into an SSEv DB?
If I have to use the 'image' data type to so this, does anyone have a code sample that would let me push an array() of numbers into an 'image' field, and unload an 'image' field into an array()?
TIA

I am an absolute beginner with SQL Server 2005 Express, and I want to make a new table in my database that stores web URLs and their Username and Password info. When I try to add a URL to the URL column, it says
Error Source: .Net SqlClient Data Provider
Error Message: String or binary data would be truncated.
The statement has been terminated.
I assume this means that the URL is too long to fit in the data type I specified, but I've tried almost every single data type there is, and I keep getting the same error. I was wondering if anyone knew what was wrong.
Thanks for any help.
I have a script to be used to backup a specific table in a weekly basis, here is the approach what I take:
1. script the source table's schema to a create
2. the new script:
If not exists (select * from sysobjects where name='EventlogHistory' and xtype='U')
CREATE TABLE [dbo].[EventlogHistory](
[LogID] [int] IDENTITY(1,1) NOT NULL,
[ProjectID] [int] NOT NULL,
[Description] [nvarchar](max) NOT NULL,
[EventType] [varchar](10) NOT NULL,
[IP] [varchar](50) NOT NULL,
[UserLogon] [varchar](30) NOT NULL,
[CreatedOn] [datetime] NOT NULL,
ArchivedOn datetime default getdate())
insert into EventlogHistory
It throws me the error message saying "String or binary data would be truncated" which is nonsense to me, I need to let sql ignore the error, it is ridiculous to do a max(len()) to find out as it should never happen, right?
I'm running into the following message, "String or binary data would be truncated. [SQLSTATE 22001] (Error 8152)" when running a sql agent job. I'm attempting to execute a stored procedure through the job. Keep in mind that when I run the stored procedure in a normal query window, it works fine and only fails when running it as a scheduled job. My guess is that it has to do with how SQL Jobs execute procedures (especially long procedures). If I use Set Ansi_Warnings OFF, the job will work fine, however, I don't know what other issues this may cause.
View 7 Replies View RelatedWe have a wrapper procedure that i am looking at replacing shortly. Basic Layout is something like like
Create proc SP_Wrapper
as
SP_LogProc 'proc1','Start'
Exec proc1
SP_LogProc 'proc1','End'
SP_LogProc 'proc2','Start'
Exec proc2
SP_LogProc 'proc2','End'
SP_LogProc 'proc3','Start'
Exec proc3
SP_LogProc 'proc3','End'
....
You get the idea. So logproc just logs that the procedure has started or stopped to a table so we can monitor it easily.
The procedure is then run by an agent job every morning. This morning we had a little bit of an odd one. In the example above we effectively got to 'proc3' being started (as it was logged). However there was then an error of String or binary data would be truncated (severity 16 i believe). However when proc3 was then manually run it worked (the data was unchanged). Then going back proc2 works fine, and its actually proc1 that has the error.
I have looked through the procs in question (and the wrapper) and cant find any error handling that is relevent (there one try and catch block completely separate at the end of the wrapper procedure for a small routine).

I have a table with 10 rows with a varbinary column
I wish to concatenate all the binary column into a single binary column and then write that to another table within the database. This application splits a binary file (Word or PDF document) into multiple segments (this is Column2 as below)
example as follows
TableA
Column1 Column2 Column3
aaa 001 <some binary value>
aaa 002 <some binary value>
aaa 003 <some binary value>
aaa 004 <some binary value>
aaa 005 <some binary value>
desired results in TableB
Column1 Column2
aaa <concatenated value of above binary columns>

We have a dll that sends a hexadecimal data (const. length) to MS SQL Server database. It's declared as String in VB, the db column data type is binary.
Here is the SQL String that has been executed successfully in Query Analyzer:

I am trying to store a byte array in a database. I want to use binary to store the data but I am confused about the type. The byte array I am trying to store is a password hash from SHA512.
I hash a plain text value then store the result in a byte array. I then want to store the byte array in the database as binary but I am confused when its asking for the size of the binary field. In nvarchar a size of 2 would mean 2 characters.
How should I choose the size of this binary field, and what does the size mean. If I choose a size of 6 does that mean 6 characters, like 010110. Or is it stored differently?
The maximum size of a plain text password is 30 characters, and the salt used to generate the SHA512 hash has a maximum size of 16, but I don't know the exact size of the salt because its randomly picked when the salt is generated.
I need to make sure the size of my binary field will hold the largest possible password hash, but I don't want it too large so its never completely used.
How is this data stored in the binary field, and what size binary field should I choose to make sure there are no problems with the password hash being truncated, yet making sure I'm not just wasting by creating a field thats too large.
Thanks!
Hello,
I need to generate HASH of text values for my app. I can generate hash values for normal fields using CHEKCSUM and BINARY_CHECKSUM function but it does not support checksum of text, ntext, image, and cursor, as well as sql_variant.
How can I generate checksums of such datatype.

Hi Folks,
After I inserted a row in my Database (row 27) I started getting this error when I try to insert, update or delete the record in the database.
I've searched about the error on google and it says that I should have a field that crossed the limit of characters.
I have only the autoincrement field, two varchar fields and a text field, neither one of the varchar fields crossed the limit, they arent even close. I found in google that one solution would be turn the field that is having problems in a text field, but the only field that actually can be causing the problem already is of the text type.
The exact error I get on VS 2005 when trying to change something in the row 27 is:
"No row was updated.
The data in row 27 was not committed.Error Source: .Net SqlClient Data Provider.Error Message: String or binary data would be truncated.The statement has been terminated.
Corret the errors and retry or press ESC to cancel the change(s)."
I need some help guyz, see ya, hugs.

Hi,
I am facing problem inserting binary data into sql data type varbinary.
I want to save an object data type in var binary data type into sql.It gives a followin error.

I do not use ASP Upload file.

Friend
I am currently developing a simple program that will upload ms-word documents to a database so users can view them within the department.
The program worked prefectly while using sql 2005 with the these fields:
FormId intFileName nvarchar(50)FileBytes varbinary(Max)
This was done in unit testing, now in system testing there is a difference.
A slight downgrade in the database and server software!
We are using sql 2000 on a 2000 server and the FileBytes datatype had to change to the following:
FormId intFileName nvarchar 50 FileBytes varbinary 8000
There is no 'Max' option in sql 2000 for the datatype varbinary.
So when the insert is perform, we get this error message:
String or binary data would be truncated.The statement has been terminated.
I am guessing it has something to do with FileBytes, because this is the only thing that changed.
I just don't know how to solve the problem.P.S.The application is in ASP.NET 2.0
Thanks,

I keep getting the error "String or binary data would be truncated." when I try to insert data into SQL Sever 2005 from an ASP.net page. Having searched thoughout the web, I know this is generally caused because one of the values being inserted is bigger than the size of the field it's going into. But, I have tested this out in many different ways, and this is not what's causing the problem.
I have tried doing the insert as a SQL statement and using the "ExecuteNonQuery" command. I have also tried running this through a stored procedure. Neither works. In both situations, I have captured the TSQL statements via SQL Profiler and run them in a query window. In both cases, the statements work just fine in a query window.
When I try to do the insert via a stored procedure, all of the statements in the stored procedure show up in SQL Profiler, including the final SELECT statement I have the indicates a successful result. But, the data does not end up in the table and the ASP.net page returns an error.
Also, I have run both the Stored Proceure and the SQL insert statement making all of the fields blank as a way of ensuring that no value can be longer than a field's size. But, in both cases I still get the same error.
Here's the line I use when doing a regular insert:
Dim Command4 = New Data.SqlClient.SqlCommand("INSERT INTO ResourceCenter(UserEmail, UserPassword, Region, FirstName, LastName, Company, JobTitle, Address1, Address2, City, StateProvince, ZipPostalCode, Country, BusinessPhone, WebSiteURL, HowDidYouFind, Industry, WhatTypeOfSolution, CompanySize, NumLogins, LastLogin) VALUES ('" & UserEmail & "', '" & UserPassword & "', '" & Region & "', '" & FirstName & "', '" & LastName & "', '" & Company & "', '" & JobTitle & "', '" & Address1 & "', '" & Address2 & "', '" & City & "', '" & StateProvince & "', '" & ZipPostalCode & "', '" & Country & "', '" & BusinessPhone & "', '" & WebSiteURL & "', '" & HowDidYouFind & "', '" & Industry & "', '', '', 1, " & Now & ")", conn2)

I am trying to pass a multi lined text field into my SQL Server database. I tried varchar and set the length to 1000 but I still can only pass upto 50 charcters. I also have tried to use other data types like nvarchar, text, and ntext but the text and ntext won't allow me to chenge the length of the field and n varchar will only allow up to 50 charcters no matter how big I make the length. Any help you can give me would be great.

I am getting a "String or binary data would be truncated" error when trying to insert large data, but this is *no where* near the maximum size of the image datatype.
Should I be declaring the size of the image parameter in my SQLCommand or something?
TIA,
Mark
Code example:
The sproc:
ALTER PROCEDURE sproc_Content_Insert
(
@ContentName varchar(250),
@ContentDesc varchar(500),
@ContentType varchar(25),
@Content image,
@LocationID int
)
AS
INSERT INTO tbl_Content (ContentName, ContentDesc, ContentType, Content, LocationID)
VALUES (@ContentName, @ContentDesc, @ContentType, @Content, @LocationID)
The method:
Public Sub SaveBinaryContent(ByRef ContentName As String, ByRef ContentDesc As String, ByRef ContentType As String, ByRef Content As String, ByRef LocationID As Integer)
'convert the content to a binary stream.
Dim ms As New System.IO.MemoryStream
Dim bf As New BinaryFormatter
bf.Serialize(ms, Content)
ms.Position = 0
Dim oConn As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim cmd As New SqlCommand("sproc_Content_Insert", oConn)
With cmd
.CommandType = CommandType.StoredProcedure
.Parameters.Add("@ContentName", ContentName)
.Parameters.Add("@ContentDesc", ContentDesc)
.Parameters.Add("@ContentType", ContentType)
.Parameters.Add("@Content", ms.ToArray)
.Parameters.Add("@LocationID", LocationID)
End With
oConn.Open()
cmd.ExecuteNonQuery()
oConn.Close()
oConn.Dispose()
cmd.Dispose()
bf = Nothing
ms = Nothing
End Sub
I'm trying to read a byte array of an image datatype from sql server, and then to put this in another field in the database. I get a byte array, but somehow the image doesn't get into the db well with the sql parameters. Does anyone have an idea how to tackle this problem?
Thanks a lot, Hugo
Hi all,
when ever i try uploadin the file to the database, i am facing this weird probs :(
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: String or binary data would be truncated.Source Error:

Line 126:dbAdapt.Update(dbSet,"tblFile1");
Line 127:
Line 128:// Get newFileID
i donno what this means :(
well the code is like this
private void Button1_Click(object sender, System.EventArgs e)
{
HttpPostedFile myFile = filMyFile.PostedFile;
// Get size of uploaded file
nFileLen = myFile.ContentLength;
nFiletype = myFile.ContentType;
// Allocate a buffer for reading of the file
myData = new byte[nFileLen];
// Read uploaded file from the Stream
myFile.InputStream.Read(myData, 0, nFileLen);
strFilename = Path.GetFileName(myFile.FileName);
if( myData.Length != 0)
{
WriteToDB(strFilename,nFiletype,ref myData);
}
}
private int WriteToDB(string strName, string strType, ref byte[] Buffer)
{
int nFileID = 0;
// Create connection
SqlConnection dbConn = new SqlConnection("Data Source=D3BKIRAN; Database=ooc;UID=sa;Password=*****");
// Create Adapter
SqlDataAdapter dbAdapt = new SqlDataAdapter("SELECT * FROM tblFile1", dbConn);
// Create and initialize CommandBuilder
SqlCommandBuilder dbCB = new SqlCommandBuilder(dbAdapt);
// Open Connection
dbConn.Open();
// New DataSet
DataSet dbSet = new DataSet();
// Populate DataSet with data
dbAdapt.Fill(dbSet, "tblFile1");
// Get reference to our table
DataTable dbTable = dbSet.Tables["tblFile1"];
// Create new row
DataRow dbRow = dbTable.NewRow();
// Store data in the row
dbRow["FileName"] = strName;
dbRow["FileSize"] = Buffer.Length;
dbRow["ContentType"] = strType;
dbRow["FileData"] = Buffer;
// Add row back to table
dbTable.Rows.Add(dbRow);
// Update data source
dbAdapt.Update(dbSet,"tblFile1");
// Get newFileID
if( !dbRow.IsNull("FileID") )
nFileID = (int)dbRow["FileID"];
// Close connection
dbConn.Close();
// Return FileID
return nFileID;
}
plz any one give me an soln for the same
thanks in advance
I seem to be getting very annoying behaviour from SQL Server and was wondering what the correct method should be...I want to store some binary data in the database and I want to use a stored procedure. I also want to pass some XML to the stored procedure where this XML contains the binary data. I will then use OPENXML to grab the binary data and stick in the table. In order to ensure the safe transmission of the binary through XML I Base64 encode it. Ok so far. The problem is that although OPENXML is supposed to assume that anything marked as Image/Binary will be Base64 encoded it then proceeds to Base64 encode it again and put that result into the database! So what am I missing, am I supposed use a CDATA section or something rather than Base64 encode my XML?
