I need to convert varbinary data to some other datatype. Is there any way by which we can change this ?
In my project requirement I am  migrating    sql server data to some other database (EXASOL) destination have no varbinary datatype supported.
how can I move this data to my destination.
Can anyone tell me what varbinary casts to ?? can I do this int[] temp=(int)DataReader["varbinaryColumn"]. Or is byte[] temp the appropiate protocol.

I have a password column that needs to be converted from varchar to varbinary. Can anybody provide me a proper CONVERT statement syntax for it?
View 12 Replies View RelatedWe 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,

Hi I have a varchar(8000) and currently XML files are stored in varchar(8000).Some times when i am doing manuplactions in my varchar column i am getting with special characters error. so now i want to keep my column varchar(MAX) and when i am doing calculations i will convert my varchar datatype to xml datatype. By doing this i hope there wont be any special character problems.
When i am doing calculations with the wellformed xml i am getting error for both convert and cast methods as below
I am trying to do convert(xml,MyVarcharColumn)
Implicit conversion from data type xml to nvarchar is not allowed. Use the CONVERT function to run this query.
Also i tried with casting and getting same problme. is there any way to convert
please suggest me
Thanks

Need to know if the varchar datatype field will ingore leading zeros when compared with numeric datatype ?
create table #temp
(

Good afternoon,
I have an issue with an ssis variable datatype.
The scenario is as follows:
I have a stored procedure:
PROCEDURE [dbo].[sp_newTransaction]
@sourceSystem varchar(50),
@txOut NUMERIC(18,0) OUTPUT
AS
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
Thanks much,

I have a field in a table that stores date of birth. The field's datatype is char(6) and looks like this: 091703 (mmddyy). I want to convert this value to a datetime datatype.
What is the syntax to convert char(6) to datetime?
Thank you in advance.
Hi,
I imported a table from Accees to SQL 7 with data in it.
I need to modify one of the datatype columns to "datetime" from nvarchar.
I tried to convert it manually, in SQL Server Enterprise Manager tool, but it gave me an error.
I also tried, creating another column "DATE2-datatype:datetime" and updating the column with the old one.
UPDATE users SET DATE2 = DATE.. But it also faild,..
How can I modify the column?
Thank you.
HI,I have a table with IDENTITY column with the datatype as INTEGER. Nowthis table record count is almost reaching its limt. that is totalrecord count is almost near to 2^31-1. It will reach the limit with inanother one or two months.In order to avoid the arithmentic overflow error 8115, we would likechange the datatype from INT to BIGINT. we hope this will solve ourproblem.How do I approch this datatype conversion?. Since the data count ishuge, that leads to a long down time of database.we need better approach or solution for this problem?. kindly give mea better solution that will reduce the total downtime of the productiondatabase.?.Regards

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
hello.
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?
thanks!
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
)
where photoseq = 27
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?

View 1 Replies View RelatedIt 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).

Hi everyone,
We're trying to migrate a varchar field from Sql2k to varbinary in a sql25k through a dtsx package. We get an error which tell us: "data will be lost".
Does anyone have any idea about that?
Thanks for your time and inputs,
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.
