Using the Byte Converter is straightforward and user-friendly. Here’s a step-by-step guide on how to utilize this tool: Input the Value: Enter the number of bits, bytes, or any other unit you wish to convert. Select Units: Choose the current unit of measurement from the dropdown menu...
SELECTright((bytea'\xDEADBEEF')::text,-1)::varbit; Result: '11011110101011011011111011101111' right(text, -1)is just the cheapest way to remove the leading backslash from the text representation. varbit(standard SQL namebit varying) is for bit strings of arbitrary length. Cast the result to...
