Needed Sql Script To Convert Binary Content
Apr 1, 2007
Hi all,
how r u everyone, guys i need a help, i have a interface in my application, adding attachments to issues, ie users can attach a file for a particular issue and if anyone have to view they ve click a link and it will download.
iam using filestream and binaryreader concept in that, ie read the file using filestream and then use binaryreader.readbytes method to convert it into byte array and store it in the database in a column with a image datatype as a binary content.
FileStream oImg;
BinaryReader oBinaryReader;
byte[] oImgByteArray;
oImg = new FileStream(sFilePath,FileMode.Open,FileAccess.Read);
oBinaryReader = new BinaryReader(oImg);
oImgByteArray = oBinaryReader.ReadBytes((int)oImg.Length);
oBinaryReader.Close();
oImg.Close();
this is the code iam using.
when i use this its taking so much of time to get uploaded. so what i thought of doing is save the file in a specific folder using some postedfile.saveas(not sure of syntax) and when the user wants to view the file they can just download the file. i can do this by googling but what i want is wat abt the existing attachments in the database. so i need a help to do this........
is it possible to create a query to read the files and convert it into original file and save it in the specific folder or do i ve to create a simple interface to create do it manually , pls someone help me what to do ......
thanks in advance.
waiting for a reply soon
Note: any unclear statement in my question kindly reply me
Wishes n Regards
Venkat.

Does anybody know
how to convert in SQL a number from decimal to binary:
Example: 'F' = 1111
I tried select convert(binary, 12.22) but SQL interprets the word 'binary' as Hex.

I need help converting a varchar field to binary.
I have a Data Control Task that has a OLE DB Source and corresponding OLE DB Destination Data Flow Task. In the referenced source table there exists a field defined as a varchar(12), in the corresponding destination table it is defined as a binary(12). How do I perform this conversion?
I tried inserting a Data Conversion Task and assigning the new data type as byte stream[DT_BYTES] and a Length = 12, but this was a bust. Output test is as follows:
Error: 0xC020901C at DFT - Windows, OLE_SRC - Windows [1]: There was an error with output column "Payload" (40) on output "OLE DB Source Output" (12). The column status returned was: "The value could not be converted because of a potential loss of data.".
Can anyone help me out here?
Regards,

hello all,
I am reading a file that contains textual data (formatted,e.g font=bold,font size=10 etc). After reading the file, i store the data read from the file to a table in Sql server 2005. But in the table, this data is stored like this:
daohORIGINAL TEXTm............
how can i just store the original text of the file in the table and get rid of these boxes? Or when i read this data from table, how to remove these boxes and get only the original text?
Thanks in advance.
I am using C# FileStream to read the file from disk. VS 2005

I have been given some data from a Mainframe (AS400?) which has some fields coded in Packed Decimal. I have been able to load the data into a SQL2005 database table, but I now need to convert the Packed Decimal data in the binary(6) field to the appropriate integer (or float) value.
The field contains values such as the following:-
0x20202020200C
0x202020022025
0x20202020DFFA
I don't know how to interpret these. Has anyone got a function that can do this for me?
I've read several articles online that explain how packed decimal works, but none tell me how to interpret the last of my three examples. Can you help?
Thanks!

I can't take full credit for this. I want to share this with Jeff Moden who did the important research for this calculation here.
All I did was just adapting some old code according to the mantissa finding Jeff made and optimized it a little
Some test codeDECLARE@SomeNumber FLOAT,
@BinFloat BINARY(8)
SELECT@SomeNumber = -185.6125,
@BinFloat = CAST(@SomeNumber AS BINARY(8))
SELECT@SomeNumber AS [Original],
CAST(@SomeNumber AS BINARY(8)) AS [Binary],
dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Converted],
@SomeNumber - dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Error]
And here is the code for the function.CREATE FUNCTION dbo.fnBinaryFloat2Float
(
@BinaryFloat BINARY(8)
)
RETURNS FLOAT
AS
BEGIN
DECLARE@Part TINYINT,
@PartValue TINYINT,
@Mask TINYINT,
@Mantissa FLOAT,
@Exponent SMALLINT,
@Bit TINYINT,
@Ln2 FLOAT,
@BigValue BIGINT
SELECT@Part = 1,
@Mantissa = 1,
@Bit = 1,
@Ln2 = LOG(2),
@BigValue = CAST(@BinaryFloat AS BIGINT),
@Exponent = (@BigValue & 0x7ff0000000000000) / EXP(52 * @Ln2)
WHILE @Part <= 8
BEGIN
SELECT@Part = @Part + 1,
@PartValue = CAST(SUBSTRING(@BinaryFloat, @Part, 1) AS TINYINT),
@Mask =CASE WHEN @Part = 2 THEN 8 ELSE 128 END
WHILE @Mask > 0
BEGIN
IF @PartValue & @Mask > 0
SET @Mantissa = @Mantissa + EXP(-@Bit * @Ln2)
SELECT@Bit = @Bit + 1,
@Mask = @Mask / 2
END
END
RETURNSIGN(@BigValue) * @Mantissa * POWER(CAST(2 AS FLOAT), @Exponent - 1023)

Server is SQL 2000
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>

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?

Using DTS package in 2000 version, I am dumping TXT file contents into SQL Table,
I have one column having date in format YYYYMMDD(20070929) and corresponding column in SQL is datetime, but it fails on data type mismatch.
I have no choice of making date column in SQL to string or Varchar etc,
is there any way to make that date column in SQL to convert the value upon transformation from format (YYYYMMDD) to M/DD/YYYY (9/29/2007).

Dear Experts,Ok, I hate to ask such a seemingly dumb question, but I'vealready spent far too much time on this. More that Iwould care to admit.In Sql server, how do I simply change a character into a number??????In Oracle, it is:select to_number(20.55)from dualTO_NUMBER(20.55)----------------20.55And we are on with our lives.In sql server, using the Northwinds database:SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2)) as a_number,cast ( STR(r.regionid) as int ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,cast (STR(r.regionid,7,2) as numeric ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044Str converts from number to string in one motion.Isn't there a simple function in Sql Server to convertfrom string to number?What is the secret?Thanks

I want to create the most effective way (google) to have content displayed on a web page.
Currently, we are updating to SQL and populating to web via calling SQL statements hardcoded to page. I want to know if this is ok to do, or should we be reading from a static XML file that is updated?
I think the XML is the way to go being that i may have answered my own question, but i was curious to what the experts on asp.net had to say.
Thanks,Nick

Hi everyone,
I'm just using TEXTBOX control to save data into my DB. My question is, if I have multiple lines of sentences, it does not store as what it looks like. For example;
Hello, Mike
It stores into the database as "Hello, Mike" and if I read from the database, it does not have seperate lines and shows it like this;
Hello, Mike
How can I store the contents into database and make the contents as original? (Sorry for the poor English, but I hope you understand it.)

HiI have developed a sql procedure for updating some xml content using SQL 2005 xQuery features.For example:Declare @xmlContent = '<books><book name="asp"/>< book name = "sql"/></books>'--Now I want to add attribute "book_id" to the xml content.SET @xmlContent.modify('insert attribute book_id{"1" } into (/books/book[@name="asp"])[1] ')SET @xmlContent.modify('insert attribute book_id{"2" } into (/books/book[@name="sql"])[1] ')SELECT @xmlContent--OUTPUT will be<books><book name="asp" book_id="1"/><book name="sql" book_id="2"/></books>QUESTIONQ1. Do we have any extension or plugin such that this SQl 2005 xquery feature can be incorporated in SQL 2000?Q2. If the answer for Q1. is no (as I expect), then do we have any TSQL feature in SQL 2000 for modifying xml content?I found all examples in SQl 2000 related with "openxml" function which performs the select kind of operations only. Like selecting data in XML format OR converting xml data in to tabular format. But I couldn't find any xml modification TSQL in SQl 2000 which can add element/attributes or change values.one workaround could be to consider xml content as string and use string functions to modify the content.But is there any more sensible approach available in SQL 2000?

Okay, moving to developing a small site that will be storing articles - that is a site largely consisting of html marked up articles with images. We already have an SQL Server so it is becoming the back-end.
So, since I'm not an SQL Server expert, some general advice on this would be appreciated? The articles, as I say in HTML (largely just markup for titles, and general text) would be stored in the DB? As Text datatypes?
How about the images...on disk or in SQL?

hi everybody,
The problem is, I have a table with one column of varchar(8000) datatype. It has got 1000's of records. Through Query Analyzer, I am not able to view my records after 257 columns in my table, even I increased my textsize by using 'set textsize' command.
Any other setting is available to correct this. Any help is appreciated.
thanks,
Vasu

I have a particular production database that on a few recent occasions has suddenly had one of it's tables empty of content. Now there are no jobs or triggers in place neither is any stored procedures that could perform a delete or alter table operation in place. The permissions have been set not to allow this either. The datatype is text only. What is intriguing is the QA server has an exact mirror and this dosen't happen. Has anyone come across this sort of phenomenon?

Hello,
I have a field in a table called 'CourseId' - the course Id should always contain a backslash somewhere in the list of numbers eg :
12342322
11231131
Unfortunately, some of the course Ids have a forward slash instead of a backslash eg :
462322/1
23/232323
How can I update the field to replace the / with a
Any help is very much appreciated.
Thanks in advance,
Anthony
