导读：刚好用到， mark一下： #! /bin/bashtb_base=tb_student_arr=("0" "1" "2" "3" "4" "5" "6" "7" "8" "9" "a" "b" "c" "d" "e" "f")GetCmd(){for value in ${arr[@]}dofor value2 in ${arr[@]}dotb_name=$tb_base$value$value2cmd="ALTER TABLE ${tb_name} AD

刚好用到， mark一下：

#! /bin/bash

tb_base=tb_student_
arr=("0" "1" "2" "3" "4" "5" "6" "7" "8" "9" "a" "b" "c" "d" "e" "f")

GetCmd()
{
	for value in ${arr[@]}
	do
		for value2 in ${arr[@]}
		do
			tb_name=$tb_base$value$value2

			cmd="ALTER TABLE ${tb_name} ADD INDEX seed (uid,name);  "
			
			echo $cmd
		done
	done
}

GetCmd $1

上面的结果就是要执行的语句， done.

嗯，tb_student_和"tb_student_"都可以
