JDBC prepareStatement doesn't work

Question

I\'m trying to use the prepareStatement function. The code is below. After it executes, it returns me a bunch of vlicense strings instead of the va

Answer 1

It has nothing to do with jdbc, prepared-statements or mysql.
It's just a wrong sql statement.

If you type:

Select 'justanexample' from Vehicle

and the table contains 4 lines, you will get 4 times

'justanexample'
'justanexample'
'justanexample'
'justanexample'

as result.

You did not specify your the table structure, but I guess the statement should somehow look like this:

select * from Vehicle where license = ?
