刚好用到, mark一下:
#! /bin/bash
tb_base=tb_student_
arr=("0" "1" "https://files.jxasp.com/image/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
