If you use Style 1 when converting from a character string to a binary value, the input character string should include the 0x prefix; if you use Style 2, it should not. And that is why simply converting a BLOB guid column to hexadecimal with SQL’s HEX () function and then splitting the string after a certain number of characters just won’t do. Instead, we have to use an abomination like this:. "/>
