Hi! I know we have 4 types of JDBC drivers such as Type 1: JDBC-ODBC Bridge Driver, Type 2: JDBC-Native API, Type 3: JDBC-Net pure Java, Type 4: 100% pure Java. Can anyone provide example drivers for all the four types of drivers?
I'm not sure how a download link for Postgresql's type 4 driver helps explain JDBC driver types, but you may want to start reading at http://faq.javaranch.com/java/GeneralJdbcQuestions, especially the answer to "Q. What are the differences between the 4 types of drivers?".
I wanted to know all the available drivers for jdbc and the categories(type 1,2,3,4) they fall into. After referring http://developers.sun.com/product/jdbc/drivers it seems oracle does not provide type 1,2 or 3 drivers. Can you moderators or other java veterans please tell me what are the drivers you have used in your projects?

Most drivers being used these days are type 4 drivers (by a wide margin, I'd guess). Being the only type that is all-Java, they're the easiest to set up and use. It was different when JDBC came out (in 1997 or so), and not many all-Java drivers existed, but no more.
We find this kind of rampant individuality very disturbing. But not this tiny ad:
