in swift xcode autocorrect keeps forcing me add comma @ end of line, don't know why or comma doing. commas @ end of line do? looked , found lots on comma use in phrase separate different values in function example, nothing why comma or used @ end of terminating line of code. code xcode wanted add comma (the comma @ end xcode): var firstrandomnumber = int(arc4random_uniform(uint32(playerarray.count)), is glitch or there i'm missing? thanks basically it's bug in fix-it , compiler's interpretation of mistake. mistake really you've forgotten final right parenthesis: var firstrandomnumber = int(arc4random_uniform(uint32(playerarray.count))) ^ but compiler doesn't quite grasp that, , interprets missing comma: these messages might improved in future version of swift.

this question has answer here: what maximum number of joins allowed in sql server 2008? 4 answers what maximum number of tables able join? or unlimited? are there shortcuts add multiple tables, without having alias , choose each field? this bad form (using * ) can keep adding tables out specifying columns so: select * table1 inner join table2 on table1.id1 = table2.id2; add table changing above to: select * table1 inner join table2 on table1.id1 = table2.id2 inner join table3 on table3.id3=table2.id2; the problem such join getting many columns , moving data around unnecessarily kills performance. don't take out clothes closet when looking shirts (i hope).
