功能:shell获取多个oracle库mysql库所有的表主键
输入:数据库连接串配置文件
输出:每张表的属主,表名,主键

shell获取mysql所有表的主键脚本如下:

#!/bin/bash
# 获取mysql所有表的主键
# get_mysql_tab_pk.sh
# mysql连接串示例 jdbc:mysql://10.23.128.146:4005/tpi|tpi_uat|uat$2022%

[ -e get_all_tab_mysql_pk.log ] && rm get_all_tab_mysql_pk.log
cat mysql_conn_str.conf |while read line
do

url=`echo $line|cut -d "|" -f 1`
user=`echo $line|cut -d "|" -f 2`
pwd=`echo $line|cut -d "|" -f 3`
my_sql="
select
CONSTRAINT_SCHEMA,table_name,group_concat(column_name order by ordinal_position separator ',') as pkcols
from information_schema.key_column_usage t
group by CONSTRAINT_SCHEMA,table_name

--connect "${url}" \
--username "${user}" \
--password "${pwd}" \
--driver com.mysql.jdbc.Driver \
--query "${my_sql}" >> get_all_tab_mysql_pk.log

done
