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();
