How to write an update query in MySQL with AES_ENCRYPT?

Question

This is my code that I wrote when user wants to change his password.

s2.executeUpdate("UPDATE user SET AES_ENCRYPT(password='"+newpw1+"','key') WHERE uid='"+pubvar.uid+"')");

But it doesn't work, can someone correct it for me and post it? Thanks.

Answer 1

you mean,

UPDATE user 
SET password = AES_ENCRYPT('" + newpw1 + "','key') 
WHERE uid = '" + pubvar.uid + "')

better use PreparedStatement to prevent from SQL Injection .

String _upd = "UPDATE user SET password = AES_ENCRYPT(?,'key') WHERE uid = ?)";
PreparedStatement pstmt = con.prepareStatement(_upd);
pstmt.setString(1, newpw1);
pstmt.setString(2, pubvar.uid);
pstmt.executeUpdate();

• PreparedStatement
