PreparedStatement set variable in quotes

Question

I have this part of select

to_date(?,'YYYY-MM-DD HH24:MI:SS')

and set param from java

stmt.setString(2, startDate);

but my startDate is String (2016-07-13 00:00:00) and I need this result

to_date('2016-07-13 00:00:00','YYYY-MM-DD HH24:MI:SS')

I can make this

stmt.setString(2, "\'"+startDate+"\'");

But I think it is bad practic.

Can I make something like this

to_date('?','YYYY-MM-DD HH24:MI:SS')

or

to_date(\\'?\\','YYYY-MM-DD HH24:MI:SS')

or something else?

Answer 1

This is a copy of Oracle Documentation :

 void setDate(int parameterIndex, Date x, Calendar cal) throws SQLException 

Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a Calendar object, the driver can calculate the date taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
