tsql - Stopping T-SQL converting Hex to ASCII -


i'm trying trimmed hex value int. converting int hex no troubles using;

convert(varbinary(1),43) --this creating 0x2b result

i want show value 2b when sort of conversion varchar(), cast or right() hex converted ascii character , can't it.

does know way of preserving hex value while removing leading 0x?

if value in range 0 255 can use brute force:

-- 1 value. declare @vb varbinary(1) = 43; select @vb [varbinary], substring( '0123456789abcdef', ascii( @vb ) / 16 + 1, 1 ) + substring( '0123456789abcdef', ascii( @vb ) & 15 + 1, 1 ) [hex];  -- test range 0 255. numbers (   select 0 number   union   select number + 1     numbers     number < 255 ),   numberswithvarbinary (     select number, cast( number varbinary(1) ) vb       numbers )   select vb [varbinary], substring( '0123456789abcdef', ascii( vb ) / 16 + 1, 1 ) + substring( '0123456789abcdef', ascii( vb ) & 15 + 1, 1 ) [hex]     numberswithvarbinary     option ( maxrecursion 0 );

extending range left exercise reader.
