greenplum给某个用户赋予整个schema下所有表的权限

Posted 2020-10-02 哟、写bug呢！

greenplum 虽然是postgresql的衍生产品

 

但是语法上略有不同

类似    grant all on all tables in schema schemaname to someone 就不行

报错提示  ERROR: syntax error at or near "all"

 

所以使用了笨办法

先生成语句

select ‘grant all on table ‘ || schemaname || ‘.‘ || tablename || ‘ to usertest;‘ from pg_tables
where schemaname = ‘panasonic_compass‘

得到

"grant all on table panasonic_compass.segment_dim to usertest;"
"grant all on table panasonic_compass.wm_offline_product_weekly_fct to usertest;"
"grant all on table panasonic_compass.customer_channel_dim to usertest;"
"grant all on table panasonic_compass.wm_offline_product_daily_fct to usertest;"

把两边的双引号替换掉然后统一执行就可以了。

 

同理赋予视图权限

select ‘grant all on ‘ || schemaname || ‘.‘ || viewname || ‘ to usertest;‘ from pg_views
where schemaname = ‘panasonic_compass‘

换主人

select ‘alter table ‘ || schemaname || ‘.‘ || tablename || ‘ owner to usertest;‘ from pg_tables
where schemaname = ‘panasonic_compass‘
