What is batch processing in JDBC
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!") ;}
}
