i want extract roughly 5 million row sample table contain somewhere between 10 million , 20 million rows. due large number of rows, efficiency key. such, trying avoid sorting rows possible, hence why avoiding dbms_random.value solution have seen in similar questions. i tried following: select * full_table sample (ceil(100 * 5000000 / (select count(*) full_table))); however, can't seem arithmetic in sample clause (ora-00933: sql command not ended - tried simple sample(10/2) , still same thing). is reasonable approach, and, if so, how calculate number of rows in sample clause? you use pl/sql dynamic sql this: declare cnt integer; begin select count(*) cnt full_table; dbms_output.put_line(cnt); execute immediate 'insert target_table' ||' select * full_tablesample (' || ceil(100 * 5000000/cnt) || ')'; end;
