sql - Maintaining the order by in union of two ordered by queries - i trying run below query looks doing wrong. (just modified sample query clear understanding) select name,total,rate business b rate > 100 order total desc union select name,total,rate business b rate <= 100 order rate asc now want union of these 2 queries , in resultant output in first row output should come first query , output sec query in same sorted order single actual query giving. let me know if still unclear. seek explain in more deep level. it's simple: utilize union all instead of union . select * ( select name,total,rate business b rate > 100 order total desc) x union select * ( select name,total,rate business b rate <= 100 order rate asc) y union preserves order coded. union removes duplicates , not guarantee order. databases sort output (to create duplicate detection easier). sql oracle11g oracle-sqldeveloper

iterator - Rust String indexing. Compare str[i] char - i wan't read strings "input.txt" , leave those, have no # (comment) symbol in start of line. wrote code: use std::io::bufferedreader; utilize std::io::file; fn main() { allow path = path::new("input.txt"); allow mut file = bufferedreader::new(file::open(&path)); allow lines: vec<string> = file.lines().map(|x| x.unwrap()).collect(); allow mut iter = lines.iter().filter(|&x| x.as_slice().chars().next() != "#".chars().next()); println!("{}", iter.next().unwrap()); } but line |&x| x.as_slice().chars().next() != "#".chars().next() smells bad me, because can |x| x[0] == "#" , can't check e.g. sec char in string. so how can refactor code? rust strings stored sequence of bytes representing characters in utf-8 encoding. utf-8 variable-width encoding, byte indexing can leave within character, unsafe. getting cod
