使用shell腳本來(lái)給mysql加索引的方法

#! /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
