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,
I want to restrict varbinary column for not to store more that 2mb image file in the database. How can i do that.
Thanks in Advance!
Hi,
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.

I have a very strange situation. I've increased the size of an NVARCHAR field from 8 to 9 in a database table. The format of the data that I enter will either be an 8 character field (123456-8) or a 9 character field (1234567-9). The '-' is critical.
It used to only accept the 8 character version, but after increasing the field size, if I try to insert the 9 character field version, it gets truncated after the '-', as though it's still only allowing 8 characters. But that only occurs when I include the '-' or other such characters like '#'. If I try to insert 1234567a9, it works. The following explains the outcomes:
Inserted Value -> Result in table
123456-8 -> 123456-8 *Correct
1234567-9 -> 1234567- *Wrong
123456789 -> 123456789 *Correct
1234567#9 -> 1234567# *Wrong
1234567a9 -> 1234567a9 *Correct
Why is it that characters such as '-' and '#' are truncating the value, but only if the string is 9 chars long?
I'm currently using a direct t-sql insert statement in SQLExpress. The field is a simple NVARCHAR(9) field.
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?
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?
Can a bitmap be added to a Varbinary field using the INSERT statement. If not what other method can I use to add a photo image (bmp or gif) to my Sql database?

How can i do the following:
Calculate the size of a varbinary(max) field or variable
Calculate the average of a varbinary(max) table column
I am using SQL 2005
Thanks for your posting
I have several tables a varbinary column in a database. They have names like CSB_BLOB or OBJECT_BLOB. Now I am having intermittent success with getting the data out.
For example this query returns readable text from this data.
0x46726F6D3A20226465616E6E6167726.....etc --data as stored in the column
SELECT CAST(CSB_BLOB AS VARCHAR(MAX)) AS 'Message' FROM OBJECT_BLOB
However this column has the following query results.
0x0001000000FFFFFFFF01000000000000000C....etc. --data as stored in column
--this query returns empty result
SELECT (CSB_BLOB AS VARCHAR(MAX)) AS 'Message' FROM CSB_STATUS_LOG
--this query returns no change???
SELECT CONVERT(VARCHAR(MAX), CONVERT(VARBINARY(MAX), CSB_BLOB, 2), 2) FROM CSB_STATUS_LOG
0001000000FFFFFFFF01000000000000000C....etc
Obviously there is a difference between the two but I am not educated enough to interpret this difference. What do I need to learn / read so I can look at the data in one of these BLOB columns and know how to convert it to something meaningful?
Something like:
1. Try to cast as varchar to see if it is text.
2. Turn into a byte array and see if it is a jpg
3. Turn into a byte array and see if it is a pdf
4. Convert it to hex and then cast as varchar
5. etc....
Just looking for some guidance on how to find a value thats 9 digits in length

I have a text field and want to know if any of the text exceeds 10,000 characters
I can do a select max(len(rtrim(convert(varchar(8000)))) on the field but I'm not able to do for more than 8000 and you can't manipulate TEXT datay type.
Any ideas?
Thanks!
I have a database on sql2000. I want to change the length of a field in Table A, but it is related to another field in Table B. When I tried to change the length of the field in Table A via
ALTER TABLE table ALTER COLUMN field varchar(5).The query analyzer generates the following error.
Server: Msg 5074, Level 16, State 8, Line 1
The object 'UQ__table__77BFCB91' is dependent on column 'field'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN field failed because one or more objects access this column.While when I tried the same query on the field in TABLE B, the query completed without any errors.
I'm sure it is possible to select all records where the length of a given field equals a certain value, but I don't know how to do it?
Can somebody tell me how?

There are two fieldsA1 nvarchar(30)A2 nvarchar(800)I know nvarchar field is alterable length, if I store a string mystring='abc' to A1 field or to A2 field, I think they use the same disk space, so I think it's always a good way to define a big length nvarchar field such as A3 nvarchar(4000) for any length string, becuase they always use the same disk space, is it right?

I have to modify field length in the table, which is part of publication. I tried to use an Enterprise Mgr and received an error message because that table is scheduled for replication.
Is any way around this beside temporary stopping and restarting replication? And actually how to do this to be sure that after restart the data will be again in sync.
We have SQL Server 2000 Enterprise Edition and Windows 2000 Advanced Server.

I have a few columns in table with default value defined as zero length string (''). I want to insert record from DetailsView which uses SqlDataSource as DataSource. In the ItemInserting event, if the data is not valid, I want to use zero length string for the column. But I always get Null instead of zero length string. The code in ItemInserting event looks like this:
If objddl.SelectedIndex > 0 Then e.Values("myFld") = objddl.SelectedItem.ValueElse e.Values("myFld") = ""End If

Hi,
I have to export data from a database in a special form (the customer wants it this way): every record in one line, and all fields in a large string. Thus, only by convendion it is defined the first seven characters being the central number, the next fivr characters the number of this spare part type, the following 30 the description, and so on...
Just at the end of every record has to be CF-LF.
all works well so far by with this code (in PHP) -
except one thing - see details below the code snippet):
$q1 = "SELECT dirc_matdata.* FROM dirc_vorgang, dirc_matdata ";
$q2 = "WHERE dirc_vorgang.rep_out> '".$anf_dat."'";
$q3 = "AND dirc_vorgang.rep_out < '".$end_dat."'";
$q4 = "AND dirc_matdaten.auftrags_nr = dirc_vorgang.auftrags_nr";
$q5 = "INTO outfile '".$drive.":/matdata.dat'";
$q6 = "FIELDS TERMINATED BY '' LINES TERMINATED BY '
';";
$query = $q1.' '.$q2.' '.$q3.' '.$q4.' '.$q5.' '.$q6;
The INT (integer) fields appear in the (plain text) output file with wrong field lengths. Although I had set the first field (i.e. the number of this type ofparts) to a length of 5, this field appears in the outfile being 10 characters long -- the maximum length of a normal INT type field (and twice as long as it should be).
Or (when set to filed type "MEDIUMINT"), it appears in the length of 8 characters only. But I need this data exactly 5 characters long in this application.
BIG QUESTION: How can I make mySQL (Ver. 4.1) write this fields into the outfile with their correct length as defined in the database structure?
Is this flaw already known in the community?
Is there any sort of "workaround"?
Thank you for every hint!

Hello,
I am running a stored procedure thru' isql.
This returns only one field.

Hi,
I am trying to upload a fixed field text file to a sqlserver table using the DTS wizard. The txt file has 111 columns and the total length of a single row is 5897. The problem is when I use the wizard to specify the starting and ending of each column, its not allowing me to specify the columns beyond the position 4095.
Is there a limitation on this? if so is there a work around ? to solve this.
Any help on this is truly appreciated.
Thanks much. :)
