运用到以下知识点：

--匹配出单引号中的字符
echo "select 'ie_bidsection',count(*) from ctpsp.ie_bidsection" | sed "s/.*'\(.*\)'.*/\1/"

--if下变量和数字比对
--lt < le <= gt > ge >= ne <> eq =
if [ "$src_tab_name" == "$tab_name" ] && [ $tab_count -lt  1000000 ];then

elif [ "$src_tab_name" == "$tab_name" ] && [ $tab_count -ge 1000000 ];then

fi

--变量自增
a=$(($a+1))
a=$[$a+1]
a=`expr $a + 1`
let a++
let a+=1
((a++))
