Could I iterate through this result set and update Col4 in Table B?

That is, using the JDBC/Result Set update X(...) methods?

For example- result String("Column Name");, result Int("Column Name");, You can update the database table from the result Set object as - Statement statement = connection.create Statement( Result Set. CONCUR_UPDATABLE); result Set.first(); // Setting the updating String result Set.update String("Name", "vnay"); // Updating the first row result Set.update Row(); An Example given below illustrate the above explanations, At first create database named student and then create a table student in the student database as CREATE TABLE student ( Roll No int(9) PRIMARY KEY NOT NULL, Name tinytext NOT NULL, Course varchar(25) NOT NULL, Address text ); Then insert the value into it as NSERT INTO student VALUES(1, ' Ram', ' B.

Tech', ' Delhi') ; NSERT INTO student VALUES(2, ' Syam', ' M.

Big Decimal big Decimal To Get = result Set Big Decimal(int Of Position To Get);

Blob blob To Get = result Set Blob(string Column Name To Get); //must be using JDBC 2.0 or above byte byte To Get = result Set Byte(int Of Position To Get); byte byte To Get = result Set Byte(string Column Name To Get); byte[] byte Array To Get = result Set Bytes(int Of Position To Get); byte[] byte Array To Get = result Set Bytes(string Column Name To Get);

It is possible to make Result Set object that is updateable and acrollable. CONCUR_UPDATABLE); Result Set rs = stmt.execute Query("SELECT * FROM Student"); The Result Set object also provides a getter method that that gets the value from the Result Set object table.

to make such type of Result Set object you need to write the following code. You need to specify only the Column name or index no of the table.
