Convert(int,sys.fn_sqlvarbasetostr(hashbytes('md5','1455985476')))

: This internal (undocumented) function converts the binary hash into its string representation (e.g., '0x792106533f84b730c64951a1ea702c78' ).

: Using sys.fn_sqlvarbasetostr is generally discouraged in production code because it is an undocumented internal function. A more standard approach in T-SQL is CONVERT(INT, HashBytes('MD5', '...'), 2) or directly casting the binary to an integer. : This internal (undocumented) function converts the binary

: Selecting a deterministic but seemingly random subset of rows (e.g., WHERE ABS(HashConvert) % 10 = 0 for a 10% sample). : This internal (undocumented) function converts the binary
