It would be nice if SQL Server Everywhere could support NVARCHAR(MAX) and VARBINARY(MAX), even if they would just be alias' for NTEXT and IMAGE. This would somewhat simplify the interoperability with SQL Server 2005 (i.e. no need to have different scripts for each database type).
Gerrit
On the ntext, text, and image (Transact-SQL) page at
http://msdn2.microsoft.com/en-us/library/ms187993.aspx
it states
"Important:
ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead. For more information, see Using Large-Value Data Types."
Considering this warning, is VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) support going to be implemented in SQL Server Compact Edition?

I am using rowVersion to detect rows that need to be re-extracted for my ETL. Â The first step in the ETL is to get MIN_ACTIVE_ROWVERSION() from the database, as well as the rowVersion from the last successful ETL run. Â Both of these values are saved in variables in SSIS. Â Since SSIS doesn't have an associated data type, these values are converted to nvarchar(512) before getting sent to SSIS. Â
I'm now trying to create a stored procedure to grab the data out of the source system. Â The sproc takes RowVersionMin and RowVersionMax as input parameters. Â Those parameters are then converted to varbinary(max), and I use them in a query to select the appropriate rows.
When I run the sproc in SSMS, it runs without a problem. Â However, when I try to use the sproc as a data source in SSIS, I get the following error: "Error converting data type nvarchar to varbinary". Why SSIS has a problem with this, but SSMS does not? Â The sproc code looks like this:
ALTER PROCEDURE [dbo].[dw_DimComment_DataLoad]
@RunType varchar(3),
@RowVersionMin nvarchar(512),
@RowVersionMax nvarchar(512)

Hi, I was wondering if any SQL Server gurus out there could help me...I have a table I'm trying to apply a full text catalog to, however no results are ever returned due to the text column being cataloged being of varbinary(max) that's being populated from a converted nvarchar(max) value - I've narrowed it down to this specifically, populating with non nvarchar text seems to work fine.To re-create the problem quickly...If I populate the column viaCONVERT(varbinary(max), 'test text')then there is no problem, I get results as expected.However if I populate the column viaCONVERT(varbinary(max), CAST('test text' as nvarchar(max)))no results are ever returned.Is this a bug with SQL Server 2005 Full Text Indexing? I'm happily creating full text catalogs when an nvarchar is not getting converted into a varbinary.I'm setting the Document Type column to '.html' (I've tried changing this to '.txt' in case it was a fault with the html ifilter but the problem persists so I believe I can rule this out).The reason I need to convert an nvarchar to varbinary is that the table holds multi-lingual text and I'm adding a html meta tag <META NAME="MS.LOCALE" CONTENT="ES"> to the beginning in order for the full text indexing word breaker to select the correct language to catalog the text with. The aim being to provide more relevant searches in users native languages (I've read a few articles that describe this technique, but it's the first time I've tried to apply it).Any pointers / suggestions would be greatly appreciated. Cheers,Gavin.

I've just started hosting my newly created Microsoft Visual Web Developer 2005 Express Edition web site. Unfortunately the Login group membership functions will not function correctly. Having contacted the web service hosting provider, They replied: "We do not support SQL express2005. The only way to use the extra functions of ASP.NET2 such as group membership is if it is using an SQL 2000 database to connect to. "
Is it possible to design web sites with Microsoft Visual Web Developer 2005 Express Edition that store membership details on an SQL 2000 database?
I've just paid £88 approx. $140 for a years subscription, have I chosen the wrong web service hosting provider?
Should I have designed the web site with a better web site design software tool that also makes designing membership login functionality easy, just as Microsoft Visual Web developer 2005 express edition?
Look forward to all comments?

I had this question for quite a long time.
It seems the latter one don't take any extra storage space than the previous one.
As long as the real string length is less than 10.
Is that mean the latter one not cost anything?
I once heard the different is when they are in memory. But not sure of it.
Can anyone explain it and provide some official reference on it?
Thank.

View 1 Replies View RelatedHi,
We have a large database table with an IMAGE field holding documents of < 1MB size.
Over time this table has become quite large and operations on it have become slow.
My question is, would changing from IMAGE to varbinary(max) make the binary storage more efficient thereby making the table operations faster.
Also, would the table size be smaller with varbinary(max)?
Thanks

i want to do something with this database but i don't know how:
there is this column that is varbinary and i want to replace just one part of its content, for example:
this is its content:
'CC08FF806785'
and i just want to change the FF for AA.
i tried using query analyzer with this:
update table
set column=replace(column,'FF','AA')
but it says something like conversion isn't allowed from data varchar to varbinary and that i should use the function "convert" but i don't know how to use that!
does anyone know how to do that?

HiI moved to SQL Server 2005 (from 2000) and noticed there is a bettervariable to deal with binary arrays.I hava a table that hold 9 columns of images (BLOB). each array has adifferent size and can be larger than 4k.I've changed the column data type from image to varbinary(max).After the chnage, the size of the table grew from 22MB to 26MB.Any idea why? I though the new variable should be better.I have another table where there are 3 columns with binaries, the sizeof the arrays there is much smaller and vary from 32bytes to 150byteslong. when I changed the data type to varbinary the size of the tableshrunk by half!!now I'm completely confused...Gilad.

Hello,
Would you please be kind to answer my question !
I have developed an ASP.NET Web application using SQL Server Express 2005 in my local PC where I have used VarBinary(MAX) for an image data storage. It is working fine in my computer. Now, I have configured my SQL Server 2005 in my production server using MyLittleAdmin, I found that, I can not set the value MAX for VarBinary, so I am forced to enter the value of varBinary = 8000. Now, When I insert image to this field more than 8KB, I get the following message,
"String or binary data would be truncated."
So, what does it mean, Is it not really possible to store image or file data in VarBinary which is more than 8KB ? if yes, then how can I configure my table for that using MyLittleAdmin ?
Regards
I have been instructed to setup a database that will allow the storing of files in binary format. I have looked at using the varbinary(max) data type on a column to store the information. I am not sure based on books online how much information this can store. I have files that could be as large as 5-10 GB in size. Will SQL 2005 support storing these in binary format with that data type?

I need to run a replace on a varbinary field but I am unsure how. I have tried mulitple different methods and to no avail. I am stumped.
I have attached a zip folder that contains a spreadsheet that shows what I am trying to do. In the first tab it shows the SQL command I use to call the field I want to change. In this case it's the Content field and I am calling it using the content_key. As you can tell the content is stored as varbinary. In the second sheet, It shows this varbinary being converted to varchar(max) and it shows what the actual text says.
The table that this information is stored is is called digitalassetcontent
I need to remove the
Code:
<STYLE>H1{font-weight:bold}H1{font-size: 14pt}OL</STYLE><H1>Product Description</H1>
That is in front of the actual product description.
Somehow I need to run this command:
Code:
Update digitalassetcontent
set content = replace(CAST(content as varchar(max)), '<STYLE>H1{font-weight:bold}H1{font-size: 14pt}OL</STYLE><H1>Product Description</H1>','')
Where CAST(content as varchar(max)) like '<STYLE>H1{font-weight:bold}H1{font-size: 14pt}OL</STYLE><H1>Product Description</H1>%' AND content_key = 'desc214974236480438500781058983745755010'
This is the error message I get when running this code: Implicit conversion from data type varchar(max) to varbinary(max) is not allowed. Use the CONVERT function to run this query.
On the varbinary field. How do I do this?
Is there something else begger than that ?? as to be in binary !! for my image..
thanx.. because 8000 is not big enought..
Hello,
I am trying to create a statement that will update many rows in a table with images, stored as varbinary(max), into a new column.
The path/file information is all stored in another table, but I can't find a way to update more than 1 at a time. Here is the statement that works for 1 row at a time:
update tblphotos set photo = (select
BulkColumn from
Openrowset( Bulk '\**servername**PropsImagesDon Giovanni 2002PropsHorses Guts 2.jpg', Single_Blob) as photo
)

but if I try to do something like this:
CREATE TABLE #temp (
photoSeq int,
photoLoc varchar(255),
photo varbinary(max)
)
INSERT #temp
select p.photoseq, f.fldlocation + p.photophyloc as files,
(select
BulkColumn from
Openrowset( Bulk f.fldlocation + p.photophyloc, Single_Blob) as photo
)
FROM txprops t
join tblfolders f on t.fldlocation = f.fldseq
join tblphotos p on p.photopropseq = t.propseq
begin tran
update a set photo = b.photo
from tblphotos a
join #temp b on a.photoseq = b.photoseq
where a.photoseq = b.photoseq
select * from tblphotos order by photophyloc
commit tran
drop table #temp
I get an error: Incorrect syntax near 'f'.
I think this is because I can only put a path in beside BULK.
I have investigated BULK and bcp commands, but cannot find anything to satisfy this. I tried the DTS package route, but am not getting very far.
Any suggestions? Is DTS the solution for me?

Hello,
I'm trying to insert a string expression into a varbinary field. I've tried it several ways, but the data does not seem to get inserted.
I map DT_STR field ("T") with varbinary field in destination table and the package executes properly, but when I see the data that it has been loaded I only see empty values (0x).
I have also tried other approaches, like converting to DT_BYTES during SSIS flow, but I always get the same result.
Any idea of how to achieve this?
Using the new encryption included in SQL Server 2005, what is a good way to determine what length I should use for the column?
For example, I am encrypting a column, its maxlength is about 30 characters, but when encrypted, the encrypted value extends from between 50 and no more than 68 characters-
So if I had a column with a max of 500 or so characters, how could I know what varbinary length I should set it to if I were to encrypt it, without actually finding the highest value I could possibly fit into the field?
Is it good practice to just make it a varbinary(max) field?

Hi,
We serialize a custom object into a byte array (byte[1000]) and store it in a SQL Server 2005 table column as varbinary(1000).
There are a lot of rows retrieved with each SqlDataReader from C# code: up to 3,456,000 rows at a time (that is, roughly 3.5 million rows).
I am trying to figure out what will be more efficent in terms of CPU usage and processing time.
We have come up with quite a few approaches to solve this problem.
In order to try a few of them, I have to know how I can extract certain "pieces" of data from a varbinary value using T-SQL.
For example, out of those 1000 bytes, at any given moment we need only the first 250 bytes and the third 250 bytes.
Total: 1000 -> [250-select][250-no-need][250-select][250-no-need]
One approach would be to get everything and parse it in C#: get the 1st and the 3rd chunks of data and discard the unneeded 2nd and 4th.
This is WAY TOO BAD.
Another approach would be to delegate the "filtering" job to SQL Server so that SqlDataReader gets only what it needs.
I am going to try a SQL-CLR stored procedure, but when I compared performance of T-SQL vs. SQL-CLR stored procs a few weeks ago, I saw that the same job is done by T-SQL a bit faster AND (more importantly for us) with less CPU consumption than SQL-CLR.
So, my question is:
how do I select certain "pieces" of varbinary column data using T-SQL?..
In other words, instead of
SELECT MyVarbinary1000 FROM MyTable
how do I do this:
SELECT <first 250 from MyVarbinary1000>, <third 250 from MyVarbinary1000> FROM MyTable
?
Thank you.

Hi Gurus,
Here is my problem-:
I have a field in the SQL 2005 database with type varbinary(50). Now when i enter value to this field, I enter a value for example 111111101. The reason to enter such a value in varbinary(50) type is, that this value is meant to grow, as each 1 and 0 in this value is a permission or right my user would have to various features of the web application, I am designing. Now when I open the table to see the data in the database, it shows as <Binary data>. But that's okay, as binary fields are mostly meant to store pictures, files etc. But when I read this value into my ASP.Net code using c#, the value as returned as 069F6BBD. After some research I realized that for decimal value 111111101, the hex value is 069F6BBD.
All I need in my code is the same thing that I entered which is 111111101.
Can someone guide me a lil bit.
Thanks in advance..

Hello,
I'm working on a website that allows users to upload small JPEG files. I followed the article at http://aspnet.4guysfromrolla.com/articles/120606-1.aspx. On the webpage I'm using a formview control to insert new records in the database. As suggested in the article I removed the "type='object'" from the insert parameters for the image column. The data is saved by using a sqldatasource with stored procedures. The image column is of type varbinary(max) and allows null values. Everythings works fine as long as the user uploads an image. The data is saved correctly and on another page the image can be viewed. However if the user does not upload a picture and tries to save the new record the following error is thrown:
�Implicit conversion from data type nvarchar to varbinary(max) is not allowed. Use the CONVERT function to run this query.�
In the formviews iteminserting event I have the following code: Dim imageBytes(fileupload1.PostedFile.InputStream.Length) As Byte fileupload1.PostedFile.InputStream.Read(imageBytes, 0, imageBytes.Length) e.Values("Image") = imageBytes What code should I use in case the fileupload1 has no file? I tried something like: e.values("Image") = dbnull.value But that doesn't work. Any suggestions?
