Question: How do I find the size of a schema in my database?
Answer: It depends on how you define "size". If you want the total disk space consumed by the schema (including indexes, tablespace free space), then the SQL query is quite simple:
selectowner, sum(bytes)/1024/1024/1024 schema_size_gig from dba_segments group by owner;
If you just want the size of the schema in terms of the space consumed by table rows, you would use a different query to calculate the schema size:
select sum(bytes)/1024/1024/1024 as size_in_gig, segment_typefrom dba_segments where owner=‘SCOTT‘ group by segment_type;
