mysql - How to convert a String to Hex and vice-versa?

问题描述:

As you know , in MySQL we have HEX & UNHEX, for example when I write like this :

select hex("Ali");

the convert result is : 416C69

and the unhex is like this : select unhex("416C69");

In MSSQL I can't convert this, could you please give me an example for both of them ???

Thanks a lot ...

网友答案:

I think this should work

SELECT     hex(CAST("Ali" AS VARBINARY)) AS Expr1

for vice versa

select CONVERT(varbinary(max), "416C69");

This will convert to varbinary, then you can convert varbinary to varchar
