使用shell脚本来给mysql加索引的方法

用shell脚本来给mysql加索引

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
