It is possible to convert a varchar(32) (a hexadecimal string like 0x81f2cf442269e111b99c1cc1deedf59c) to a bigint in sql server ?
I have tried this :
select convert(bigint, convert (varbinary(16), '0x81f2cf442269e111b99c1cc1deedf59c', 1))
but I am not sure that it works with higher and lower values.
2 answers with examples. BOTH fundamentally wrong.
CAN NOT BE DONE. Anyone cares running a basic math check first?
32 hex = 16 bytes.
Biging: 8 bytes.
All your code is one thing – useless. You CANNOT convert a 32 hex string with 16 bytes worth of numbers into a 8 byte number. Only in very few cases (upper 8 bytes all 0).
