• Java API Method Run Times

• Java: Prepare a statement without a connection

  - by r3zn1k

  I'm trying to generate some sql files in my java application. The application will not execute any sql statements, just generate a file with sql statements and save it. I'd like to use the java.sql.PreparedStatement to create my statements so that i don't have to validate every string etc. with my own methods. Is there a way to use the PreparedStatement without the calling java.sql.Connection.prepareStatement(String) function, because I don't have a java.sql.Connection?

I do however want to use whatever technique I choose everywhere in my Erlang application for consistency, and not just for strings and lists. Any advice?

Does it make sense to make the char also const? I always try to use const on pointer parameters but when something is called by value, I normally leave the const away. What are your thoughts?
