How can i convert binary(16) to Integer or numeric?

HI!!!:shocked:

Im trying to convert 0x00085180F0A2D511B69600508BE96424 to Integer or numeric format.

I just tried, At to many forms and combinations of that query
Help me !!!

SELECT CAST(CAST(CAST("field name " AS nvarchar) AS varbinary) AS float)

select cast(cast("field name " as varbinary)as integer)

select convert(int," field name") from FILE

select convert(varchar," field name") from FILE

The only answer that I have is
-1947638748 or or

And if I try with to many rows of the field at the same format,
It Answer me the same: -1947638748 for all the rows.

Thank`s for allcreate table #t1(f1 binary(16))

select *
from #t1

insert into #t1 values(convert(binary(16),'0x00085180F0A2D511B6960 0508BE96424'))

select convert(integer, f1)
from #t1

--The result is 1093813301. I dont see -1947638748

drop table #t1|||:D THANK YOU!!!, forXLDB

Just one more question please

Whats the reason for the space in the middle of the expression?

Before convert

Original Expresin
'0x00085180F0A2D511B69600508BE96424'

Convert expresin
'0x00085180F0A2D511B6960 0508BE96424'|||thank you...|||Sorry, but the actual answer is MUCH larger! You can't express that VARBINARY value as an integer, or even as a NUMERIC(38) which is the largest SQL Server will allow. The following code shows what I mean:DECLARE
@.b VARBINARY(16) -- binary image to convert
, @.i INT -- Which byte we're working on
, @.m FLOAT -- Multiplier for this byte
, @.a FLOAT -- Accumulator

SET @.b = 0x00085180F0A2D511B69600508BE96424
SELECT @.i = DataLength(@.b), @.m = 1, @.a = 0 -- Start with lowest order byte

WHILE 0 < @.i -- While bytes left to process
BEGIN
-- SELECT @.a, @.m, @.i, SubString(@.b, @.i, 1) -- Show your work
SELECT @.a = @.a + (@.m * CAST(SubString(@.b, @.i, 1) AS INT))
SELECT @.m = 256 * @.m, @.i = @.i - 1 -- Prepare for next byte
END

SELECT @.m -- Show results-PatP|||Thanks Pat Phelan

I like that explication step by step.
It really please me.sql

How can I alter an int column to IDENTITY

Hi!
I have to copy complete table with auto increment column.
I create integer column, copy the data into it and want to alter it to
integer IDENTITY(1,1) PRIMARY KEY.
This SQL command cause an error : ALTER TABLE TableName ALTER COLUMN
ColumnName int IDENTITY(1,1) in Query Analyzer.
In SQL-DMO the identity property of the column is read only after the
creation.
This SQL command is good : SET IDENTITY_INSERT TableName ON
But I can insert rows only from SQL command not from an OLEDB recordset.
Exists the way to alter a column to IDENTITY not from Enterprise Manager?
I will be glad of any answer.
Regards,
Imre AmentNo, you can't alter a column to give it the IDENTITY property. You can drop
and recreate the column (if your table is empty). In the scenario you
describe, you can create the table _with_ the integer column with IDENTITY,
then SET IDENTITY_INSERT TableName ON, copy in the data, and then set
IDENTITY_INSERT off again.
