SELECT CONVERT(int, CONVERT(varbinary, ’0xFF’, 1)) returns 255

so replace ’0xFF’ with any other hex value and try. Remember to always include ’0x’ in the beginning.

i have hex like “0605040B8423F0660601AE02056A00″
want to convert in human readable string.

pls help …..

declare @hex varchar(64) = ’0x00FF’
select cast( CONVERT(VARBINARY,’0x’+right(’00000000′+replace(@hex,’x',”),8),1) as int)

This could easily be made into a function.

SELECT CONVERT(VARBINARY(8), 65535),CAST(0x0000FFFF AS INT),
– If the value is a string without the 0x
CAST(CONVERT(VARBINARY, ‘ffff’, 2) AS INT),
CAST(CONVERT(VARBINARY, ’0000ffff’, 2) AS INT),
– or if your string has the 0x
CAST(CONVERT(VARBINARY, ’0x0000FFFF’, 1) AS INT),
CAST(CONVERT(VARBINARY, ’0xFFFF’, 1) AS INT)

0x0000FFFF,65535,65535,65535,65535,65535

please run this,

select convert(varbinary(2),unicode(N’B’))
go
declare @tmp_var varchar(10)
SET @tmp_var = sys.fn_varbintohexstr(convert(varbinary(2),unicode(N’B’)))
select @tmp_var ‘tmp_var’

;)

Thanks,
Biju

please run this,

select convert(varbinary(2),unicode(N’B'))
go
declare @tmp_var varchar(10)
SET @tmp_var = sys.fn_varbintohexstr(convert(varbinary(2),unicode(N’B')))
select @tmp_var ‘tmp_var’

;)

Thanks,
Biju

Thanks for your reply..:)

Please answer this,

select convert(varbinary(2),unicode(N’B'))
go
declare @tmp_var varchar(10)
SET @tmp_var = convert(varbinary(2),unicode(N’B'))
select @tmp_var ‘tmp_var’

Execute this query….

When a varbinary value is assigned to a varchar type, then it shows NULL. Why???

By
Biju.K.S

DECLARE @hexstr VARCHAR(10); SET @hexstr = ‘ffff’
DECLARE @rez BIGINT; SET @rez = 0
WHILE @hexstr ”
BEGIN
SET @rez = @rez * 16 + CHARINDEX(LEFT(@hexstr,1),’0123456789ABCDEF’) – 1
SET @hexstr = SUBSTRING(@hexstr,2,100)
END
PRINT @rez

Without loop, in one SELECT statement:

DECLARE @hexstr VARCHAR(10); SET @hexstr = ‘ffff’
DECLARE @rez BIGINT;
SELECT @rez = ISNULL(@rez,0) * 16 + CHARINDEX(substring(@hexstr,n.number+1,1),’0123456789ABCDEF’) – 1
FROM MASTER..spt_values n WHERE n.TYPE=’P’ AND n.number<len(@hexstr)
PRINT @rez

Vedran Kesegic

declare @hex varchar(10);
set @hex = ‘BD12′;

declare @retval int;
set @reval = — 48402 via some magic.

Now, this being the wacky world of SQL, the best solution is gonna be something involving a set operation on tables, so let’s start with a permanaent table mapping hex digits to their values:

CREATE TABLE [HexDigits](
[Digit] [char](1) NOT NULL,
[Value] [int] NOT NULL,
CONSTRAINT [PK_HexDigits] PRIMARY KEY CLUSTERED ([Digit] ASC) )

INSERT INTO [HexDigits] VALUES (’0′, 0);
INSERT INTO [HexDigits] VALUES (’1′, 1);
– etc
INSERT INTO [HexDigits] VALUES (‘E’, 14);
INSERT INTO [HexDigits] VALUES (‘F’, 15);

Then, given a similar (presumably temporary) table mapping digits in the string we want translated to their digit position (count from the right), such as this,

CREATE TABLE [HexString](
[Digit] [char](1) NOT NULL,
[Pos] [int] NOT NULL
CONSTRAINT [PK_HexString] PRIMARY KEY CLUSTERED ([Digit] ASC) )
INSERT INTO [HexString] VALUES (‘B’, 4);
INSERT INTO [HexString] VALUES (‘D’, 3);
INSERT INTO [HexString] VALUES (’1′, 2);
INSERT INTO [HexString] VALUES (’2′, 1);

Then we have the simple query

select SUM(POWER(16,(pos-1))*Value)
From HexString s, HexDigits d
where s.Digit = d.Digit

The trick here will be the convert the original string (“BD12″, in this example), into the rows if the HexString table. I don’t know of a good way to do that, but I’m sure someone knows a simple way to do that.

SELECT CONVERT(varchar(100),0x123456789abc123,1)+’?’
SELECT CONVERT(varbinary,’0x0123456789ABC123′,1)+0×0

Notice that on SQL Server 2005, the above queries will not yield an error, but you will get different results (the same as if we used style 0).

SELECT CONVERT(VARBINARY(8), 659604),0x000A1094*1

If it is decimal, use cast function

SELECT CONVERT(VARBINARY(8), 659604.1),cast(0x07010001C9A56400 as decimal(12,2))

First I enable CLR support on Sql Server.

EXEC sp_CONFIGURE ‘clr enabled’ , ’1′
GO
RECONFIGURE;
GO

Then I create a simple DLL assembly called DBClasses with a static class named StringFormatFunctions and a static method HexToInt.

public partial class StringFormatFunctions
{
[SqlFunction(IsDeterministic = true)]
public static int HexToInt(string input)
{
return int.Parse(input, System.Globalization.NumberStyles.HexNumber);
}
}

Next I load it to Sql Server.

CREATE ASSEMBLY DBClasses
FROM ‘C:\path\DBClasses.dll’
WITH PERMISSION_SET = SAFE

Finally I create a little function for it.

CREATE FUNCTION HexToInt(@input nvarchar)
RETURNS int
AS
EXTERNAL NAME DBClasses.StringFormatFunctions.HexToInt

And now I can start to use it.

SELECT dbo.HexToInt(‘ffff’)

SELECT CONVERT(INT, 0×00000100)
SELECT CONVERT(VARBINARY(8), 256)

I do not pretend to be the author, but i am using this for a long time

create function fn_HexToIntnt(@str varchar(16))
returns bigint as begin

select @str=upper(@str)
declare @i int, @len int, @char char(1), @output bigint
select @len=len(@str)
,@i=@len
,@output=case
when @len>0
then 0
end
while (@i>0)
begin
select @char=substring(@str,@i,1), @output=@output
+(ASCII(@char)
-(case
when @char between ‘A’ and ‘F’
then 55
else
case
when @char between ’0′ and ’9′
then 48 end
end))
*power(16.,@len-@i)
,@i=@i-1
end
return @output
end
