Row Level Security (RLS)

Hello,

I need to implement RLS.
I have 2 tables (below). Table 1 has all the users with their emails and Title. Table 2 has data which needs to be presented based on RLS, however some records can be viewed by multiple users based on their Titles.  I can create a realtionship between those 2 tables either by ID, Username, or Title.  Thanks in advance.

 

Table 1:

IDNameUsernameTitle
1Johnjohn@xyz.comManager
2Jerryjerry@xyz.comDirector
3Marymary@xyz.comManger
4Suesue@xyz.comAnalyst
5Alexalex@xyz.comDeveloper

 

Table 2

RowidWho can ViewCol1Col2
101Manager/Director  
102Manager/Director  
103Manager/Director  
104Manager/Director  
105Analyst / Developer  
106Everyone

@sabeensp  - You could have a bridge table that contains a row for each combination of Table2 RowID and Title. Then, Table1 will filter the Bridge table and the Bridge table will filter Table2.

Hope this helps,

Nathan

@Anonymous Data table has over 10M rows creating mutiple combination would be hard, but thanks for the tip.

Is the RLS defined row-by-row for 10M rows? Or is there some other attribute that can be exploited?

The Bridge table could instead be the distinct combinations of Who can View and Title. Then use those two columns in the relationships.
