Quick question here. I am working with a database which uses Binary(8) as an id(ie, contact_id is binary(8), and connects 2 tables). I can already extract the binary data (in the form 00-00-00-00-00-00-ab-cd). I know that there exists a contact_id 0x0000000000001989 (hex) however, when I attempt this query...
"SELECT * FROM Support_Incident where Contact_Id = '0x0000000000001989'". I get no results. What have I done wrong?
here is my problem:
i have a variable @sid_x as binary(16) = 0x4CF254AB0BA5D411AA3E00508BC5C413
and i want to use it as argument in sp_addlogin statement.
select @sqlcmd = 'sp_addlogin "test", @sid = ' + @sid_t
/* this doesn't work, because @sid_t is binary... */
select @sqlcmd = 'sp_addlogin "test", @sid = ' + convert (char (20), @sid_x)
/* this doesn't work either, because it doesn't convert to binary text */
my question, is there any way i can get @sid_x in follow text format
0x4CF254AB0BA5D411AA3E00508BC5C413 ?
Thanks a lot!
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)
END
Thanks again Jeff!

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?

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.

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

After serializing the class I need to save it in an a SQL 2005 database.But all the examples I followed use the filename ... Anyway, do I need to do something to save this into an SQL 2005 database or can I use it as follows? And how can I use this?This is the first time I do something like this so I am a little bit confused.Thanks,Miguel

I have a binary column with length 20 in SQL server table. I store dynamically C# byte[] value range from 0 to 19. So for example, If I store length of 16 and when I try to retrive it back into byte [] in C# it returns whole length 20. When I see in debug it has value from 0 to 15 which I want to use but from 16 to 19 is zero. How can I get just length value which I stored.
I use DataRow to get whole row and from the row object I extract byte [] based on column name.
Thank you in advance....
