mysql批量数据脚本

1 建表

create table dept(  id int unsigned primary key auto_increment,  deptno mediumint unsigned not null default 0,  dname varchar(20) not null default "",  loc varchar(13) not null default "")engine=innodb default charset=gbk;create table emp(  id int unsigned primary key auto_increment,  empno mediumint unsigned not null default 0,/*编号*/  ename varchar(20) not null default "",/*姓名*/  job varchar(9) not null default "",/*工作*/  mgr mediumint unsigned not null default 0,/*上级编号*/  hiredate date not null,/*入职时间*/  sal decimal(7,2) not null, /*薪水*/  comm decimal(7,2) not null,/*红利*/  deptno mediumint unsigned not null default 0/*部门编号*/)engine=innodb default charset=gbk;

2 设置参数

show variables like 'log_bin_trust_function_creators';set global log_bin_trust_function_creators=1;

3 创建函数

a.随机产生字符串 delimiter $$ create function rand_string(n int) returns varchar(255) begin   declare chars_str varchar(100) default 'qwertyuiopasdfghjklzxcvbnm';   declare return_str varchar(255) default '';   declare i int default 0;   while i

4 创建存储过程

a.创建往emp表中插入数据的存储过程delimiter $$create procedure insert_emp(in start int(10),in max_num int(10))begin declare i int default 0; /*把autocommit设置成0*/ set autocommit= 0; repeat set i=i+1; insert into emp(empno,ename,job,mgr,hiredate,sal,comm,deptno) values((start+i),rand_string(6),'SALESMAN',0001,curdate(),2000,400,rand_num()); until i=max_num end repeat;commit;end $$b.创建往dept表中插入数据的存储过程delimiter $$create procedure insert_dept(in start int(10),in max_num int(10))begindeclare i int default 0; set autocommit=0; repeat set i=i+1; insert into dept(deptno,dname,loc) values((start+i),rand_string(10),rand_string(8)); until i=max_num end repeat; commit; end $$

5 调用存储过程

call insert_dept(100,10);//从deptno为100起插入10条随机生成数据call insert_emp(100001,5000000);//从empno为100001起插入5000000条随机生成数据
