Curently I had the table with the plain text and I want to encrypt these passwords by using the following sql statement but I got the error mesages.. Any suggestion? update vpn set password = AES_ENCRYPT(select password from mytable, "abcdffffdsfddafdasfddasd").
Do you want vpn.password set to the same value in all rows? I would have expected a WHERE clause on the select statement that somehow correlates mytable with vpn.
Anyway, the immediate cause of the syntax errors is the fact that a subselect needs to be enclosed in parentheses:
update vpn set password = AES_ENCRYPT((select password from mytable), "abcdffffdsfddafdasfddasd");
