Stats not reflected in System tables
Hi ,
I'm collecting statistics on the column and the whole table, but it is not reflected in the projections and projection_columns table.
Tried executing analyze_statistics with 100%, but still couldn't see it in system tables.
Please let me know if I'm missing anything.

Got the answer, it is because the table was full refreshed after the stats was collected. So a table with 0 columns won't collect any stats.
I hope my assumption is correct.
Yes, your assumption is correct, no data, no statistics.
Thank you.
One more doubt. I have collected stats on the tables and columns with which I join the two tables.
But in the explain plan it shows NO STATISTICS.
