Here's an alternative to Clinton Herring's ufn_vbintohexstr which should be much faster with large varbinary values. First, in his original version, the inner-loop CASE statements can be replaced with this: select @value = @value + CHAR(@vbin/16+48+(@vbin+96)/256*7) +CHAR(@vbin&15+48+((@vbin&15)+6)/16*7) How does it work? By adding 6 to a hex-digit in (@vbin&15), you have a value from 16 […]

This is just an optimized version of Daniel Payne's two scripts, base64_encode and base64_decode, with changes to end-of-block handling and a bug fix or two. If the encoded string ends in =, the last character is truncated. If ending in ==, two characters are chopped off. That seems better than replacing NUL characters with spaces, […]

Challenged by Hans Lindgren's stored procedures of the same name, I created this. Note that it produces strange results on non-hexadecimal strings, overflows at 0x80000000, and could have issues with byte-ordering on some architectures.How does it work? Well, the distance between one after '9' (':') and 'A' is 7 in ASCII. Also, if I subtract […]

Hans asked if it could be faster. This is about 10% faster; not much. His is admittedly more readable, and mine will act very strangely with invalid hex digits.How does it work? I'm converting the string '1234' to the value 0x31323334 (for example), then subtracting '0000' so that it is 0-based in each byte (CONVERT(INT,0x30303030) […]
