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;

i came solution display today's date without leading zeroes in month or day when it's single digit (so instead of 08/03/2017 8/3/2017, etc.): =text(month(now()),"0") & "/" & text(day(now()),"0") & "/" & text(year(now()), "0000") displays: that formula displays today's date. typically i'd whatever , move on, of cells displaying range of dates (the first of month, current day, , last day of month etc.), have in of cells long chain of formulas. is there simpler way display dates without leading zeroes (and text)? from files: text makes use of format codes display numbers in more readable format, or combine numbers text or symbols. so, text function saying =text(value want format, "format want apply") the general format date d/m/yyyy display month & day no leading 0 , 4 digit year. write =text(today(),"a") , convert todays date letter a. in case n
