How can i query this colmn开发者_运维百科..if I wanted something like:
SELECT Name FROM Users WHERE ID = ®â{Õ■K!Eòû▓♫;#§ø
THanks
Several RDBMS (I thinks at least MySQL ans MS SQL Server) use the 0x…………
notation where you put 0x
+ your binary bytes in hexadecimal pairs, e.g. SELECT Name FROM Users WHERE ID = 0x402041
matches id '@ A'
.
PostGreSQL uses escaping and the bytea
type.
I've also read something about the format X'402041'
.
This is depedent on your SQL flavour, you should check the corresponding documentation for "binary litterals" or "binary strings".
