Image Datatype In SQL 2000 To Varbinary(max) In SQL 2005
May 9, 2008We used SSIS to move data from a table in SQL 2000 which had a column with the image datatype to a column in a table in SQL 2005 that has a datatype of varbinary(max). No errors were produced from the SSIS package.
There were a number of records where the DATALENGTH of the column with the image datatype was greater than 8000. Was the data truncated for these records?
This is probably a very elementary question, but I am not familiar with the application or the data.
Below is the source table in SQL 2000 and a select count(*) ...
CREATE TABLE [dbo].[LSCHANNELCUTDATA](
[UIDCHANNELCUT] [numeric](19, 0) NOT NULL,
[VALUECODES] [image] NULL,
...
selectcount(*)
from[LSCHANNELCUTDATA]
whereDATALENGTH ( [VALUECODES] )> 8000
Encryption Varbinary Length
Nov 9, 2006Using 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?

Ambiguous Length Varbinary Variable
Jun 24, 2008Hi,
I'm trying simple code:
declare @varbinary varbinary(8000)
set @varbinary = 2592
print len( @varbinary )
number length
2590 4 bytes
2591 4 bytes
2592 3 bytes ????
2593 4 bytes
All number in range 1 - 9000 has length 4 bytes except these numbers:
32,288,544,800,1056,1312,1568,1824,2080,2336,2592,2848,3104,3360,3616,3872,4128,4384,4640,4896,5152,5408,5664,5920,6176,6432,6688,6944,7200,7456,7712,7968,8480,8736,8992
These numbers has length 3 bytes !
Why?
I´m using varbinary variable to transport ID values and parsing in loop
set @cnt = len( @binEmpIDList ) / 4 -- 4 length
....
insert into @List( ID ) values( substring( @varbinary, @i * 4 + 1, 4 ) )
...
but this algorithm malfunctioning in enumerated numbers.
Please help, how correct this.
ID values in @varbinary too much. I cannot using convert varbinary to bigint and convert bigint to string.

From 'image' To 'varbinary(max)'
Apr 1, 2008HiI 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.

How To Compare Image/varbinary Column
May 5, 2008what is the best way of comparing image/varbinary and nullable column in sql server?
this is what i do to find out the different in image column in 2 tables sharing the same structure:
Select *
From TblA s
Left Join TblB c On
s.Id = c.Id And Coalesce(Convert(VARBINARY(MAX), c.Image),'') <> Coalesce(Convert(VARBINARY(MAX), s.Image),'')
Where c.Id IS NULL
alternatively, i was thinking to compare the column with the size, but worry about the accuracy:
Select *
From TblA s
Left Join TblB c On
s.Id = c.Id And ISNULL(Datalength(c.Image),0) <> ISNULL(Datalength(s.Image),0) Where c.Id IS NULL
any suggestion/advise will be appreciated ~

View 12 Replies View RelatedTimeouts On Delete With Image And Varbinary(max) Data
Oct 8, 2007I have a database that I am using as an archive for emails and am storing them in varbinary(max) data types. The database works fine for inserts and retrieval but I cannot delete large sets of records ( > 30K) without it timing out. I assume this is because SQL server isn't simply releasing the handle to the blob but is instead doing a lot of work reclaiming the space.
Is there any flag I can set or approach I can use to resolve this issue?
I was considering moving the blobs into a seperate simple table and putting async triggers on the primary to delete the blobs, will this work?
Any ideas are appreciated. Besides the "store files in the file system" idea.

Changing Datatype Length
Jul 20, 2005Hi all,I need to change a varchar from 35 to 50. In the SQL Server books online it says that SQL Server actually creates a new table when youchange the length. I ran a test in a test database and it appears theonly thing that changes is the length. All the data remains in tact.The table with the column I want to modify is very critical. Is thereany chance I would loose data if I change the length to a larger size? Iam making a back up of the table just in case. Thanks,Kelly
