addBatch()用法

 PreparedStatement.addbatch()的使用 
Statement和PreparedStatement的区别就不多废话了,直接说PreparedStatement最重要的addbatch()结构的使用. 

1.建立链接    
  Connection connection =getConnection(); 

2.不自动 Commit 
connection.setAutoCommit(false);   

3.预编译SQL语句,只编译一回哦,效率高啊 
PreparedStatement statement = connection.prepareStatement("INSERT INTO TABLEX VALUES(?, ?)");   

//记录1 
statement.setInt(1, 1); 
statement.setString(2, "Cujo"); 
statement.addBatch();   

//记录2 
statement.setInt(1, 2); 
statement.setString(2, "Fred"); 
statement.addBatch();   

//记录3 
statement.setInt(1, 3); 
statement.setString(2, "Mark"); 
statement.addBatch();   

//批量执行上面3条语句. 
int [] counts = statement.executeBatch();   

//Commit it  到(DB)里面
