这种方法是最基本的方法,大多数人一开始都会想到这种方法。但是Insert语句似乎并不适合大批量的操作,是不是这样呢?
本方法中将100万数据分为10个批次,每个批次10万条,每10万条1个事务,分10次导入数据库。
基本语句:Insert Into TableB (Value1) values (‘”+i+”’)
说明:语句中的i是宿主程序中的一个累加变量,用于填充数据库字段中的值。
-This method is the most basic way, most people will think of this approach. Insert statement does not seem suitable for high-volume operations, is not this it? The data of this method will be 100 million divided into 10 batches, each 100,000, one transaction per 100,000, 10 times to import the database. Basic statement: Insert Into TableB (Value1) values (' " +i+" ' ) : i statement is an accumulation variable in the host program, used to populate the database field values.
