: This is an internal, undocumented SQL Server function that converts the binary hash into its hexadecimal string representation, prefixed with 0x .
: If the input was a Unicode string (e.g., N'1152985483' ), the resulting hash and integer would be entirely different because HASHBYTES is sensitive to data types. : This is an internal, undocumented SQL Server
: This attempts to cast the resulting hexadecimal string into a 4-byte integer. Because the MD5 hash is much larger than an integer (16 bytes vs 4 bytes), SQL Server typically evaluates the rightmost (least significant) 4 bytes of the hex string to produce the integer result. Resulting Values Based on the input string '1152985483' : MD5 Hex Result : 0x25568B6B0BFA42D61326E4AD2E6957C6 : This is an internal
