mysql存储中使用while批量插入数据(批量提交和单个提交的区别)_Mysql_

    while '条件' do             循环体语句;     end while;

drop procedure if exists test_insert; delimiter $$ create procedure test_insert(n int)     begin     declare v int default 0;     set AUTOCOMMIT = 0;     while v < n         do                 insert into test(second_key, text, field_4,status, create_date)                 values ((v*10),                 concat('t',v),                 substring(md5(rand()), 1, 10),                 'good',                 adddate('1970-01-01', rand(v) * 10000));         set v = v + 1;      end while;       set AUTOCOMMIT = 1; end$$ delimiter ;
