mysql - What's is better for a members database? -

-

hi , thanx reading post having little trouble learning database in mysql. have set recently, had person tell me members table slow , useless if intend have lots of members!

i have looked on lot of times , did google searches don't see wrong it, maybe because new @ it? can 1 of sql experts on , tell me whats wrong please :)

-- -- table structure table `members` --  create table if not exists `members` (   `userid` int(9) unsigned not null auto_increment,   `username` varchar(20) not null default '',   `password` longtext,   `email` varchar(80) not null default '',   `gender` int(1) not null default '0',   `ipaddress` varchar(80) not null default '',   `joinedon` timestamp not null default current_timestamp on update current_timestamp,   `acctype` int(1) not null default '0',   `acclevel` int(1) not null default '0',   `birthdate` date default null,   `warnings` int(1) not null default '0',   `banned` int(1) not null default '0',   `enabled` int(1) not null default '0',   `online` int(1) not null default '0',   primary key (`userid`),   unique key `username` (`username`),   unique key `emailadd` (`emailadd`) ) engine=myisam  default charset=latin1 auto_increment=19 ;  -- -- dumping data table `members` --

it's going site faqs/tips games, expect lots of members @ 1 point later on thought ask make sure it's ok, thanx again peace.

did other person explain why think slow , useless?

here's few things think improved:

email should longer - off top of head, 320 should long enough email addresses, might want up.

if int(1) fields simple on/off fields, tinyint(1) or bool instead.

as @cularis points out, ipaddress field might not appropriate type. int unsigned better varchar ipv4. can use inet_aton() , inet_ntoa() conversion. see:

best field type ip address?
how store ipv6-compatible address in relational database

as @delan azabani points out, password field long value storing. md5 produces 32 character string, varchar(32) sufficient. switch more secure sha2, , use mysql 'sha2()' function.

look using innodb database engine instead of myisam. offers foreign key constraints, row-level locking , transactions, amongst other things. see should move myisam innodb ?.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
