In jdbc1.1, the connection is obtained through the DriverManager class where as jdbc1.2 supports getting connection through DataSource.

Hai, I am vineel.

I would like to tell what i know regarding this question.



1) In JDBC 1.1 the cursor can be moved only in one direction i.e in forward direction where as in jdbc 1.2 the cursor can be moved in both direction.



2) In JDBC 1.1 we cant read the desired record.if we want to read 5th record than we have to call next method five times.where as in jdbc 1.2 we can read desired record by using absolute(),and relative()



3) In JDBC 1.1 the resultset obtained cannot be updated. this is only for reading purpose.where as in jdbc 1.2 it can be updated.



4) In JDBC 1.1 we cannot use SQL3 data types like BLOB,CLOB,STRUCT,ARRAY.where as we can use in jdbc 1.2



5) Batch updates are not supported in jdbc 1.1 where as in jdbc1.2 they are supported



Thanks
