mysql数据库tpch测试总结

首先开启mysql的load data功能，解决办法：

vi /etc/my.cnf

添加

local-infile=1

重启数据库

连接数据库的时候，用

mysql --local-infile=1 -uroot -p123456 -P3306 -hlocalhost

然后就可以导入数据了

	sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,
	sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,
	avg(l_quantity) as avg_qty,
	avg(l_extendedprice) as avg_price,
