This article will explain in detail what batch processing is in JDBC. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Go directly to the code:

Package

Cn.zhou.epet.test

Import

Java.sql.*

Public

Class Addbatch {public

Static void main (String [] args) {Connection connection =

Null;PreparedStatement stmt =

Null;try

{/ /

Load the database driver Class.forName ("oracle.jdbc.driver.OracleDriver"); / /

Connect to database connection =

DriverManager.getConnection ("jdbc:oracle:thin:@localhost:1521:bdqn"

"epet", "admin"); stmt =

Connection.prepareStatement ("insert"

Into master values (master_seq.nextval,?) ")

Connection.setAutoCommit (false); / /

Transaction Begin, so that the program does not automatically commit the transaction stmt.setString (1

"QQ"); stmt.setString (2

"RR"); stmt.setInt (3

1); stmt.addBatch (); / /

Add batch 1

Stmt.setString (1

"WW"); stmt.setString (2

"EE"); stmt.setInt (3

1); stmt.addBatch (); / /

Add batch 2

Stmt.setString (1

"VV"); stmt.setString (2

"AA"); stmt.setInt (3

1); stmt.addBatch (); / /

Add batch 3stmt.executeBatch (); / /

Execute batch processing

Connection.commit (); / /

Commit transaction

Connection.setAutoCommit (true); / /

Transaction End, let the program automatically commit transactions (default) System.out.println ("dd");} catch

(ClassNotFoundException e) {e.printStackTrace (); System.out.println ("failed to load driver class successfully!");} catch

(SQLException e) {e.printStackTrace (); System.out.println ("an exception occurred when executing a SQL statement!") ; try

{if

(connection! = null) {connection.rollback (); / /

Transaction rollback connection.setAutoCommit (true); / /

Let the program automatically commit the transaction (default)}} catch

(SQLException E1) {e1.printStackTrace ();}} catch

(Exception e) {e.printStackTrace (); System.out.println ("other exceptions!") ;}

Finally {try

{if (stmt

! = null) {stmt.close (); stmt =

Null;} if

(connection! = null) {connection.close (); connection =

Null;}} catch

(SQLException e2) {System.out.println ("exception occurred while shutting down the database!") ;}

}
