php - sql select query where date is greater then, including php variables -


already read other treads regarding matter, cant find answer includes php variables.

i want select first 100 new records after date of database. can't work.

$connstr =     'odbc:driver={microsoft access driver (*.mdb, *.accdb)};' .     'dbq='.$ini_project['general']['document_location'].';';  $dbh = new pdo($connstr); $dbh->setattribute(pdo::attr_errmode, pdo::errmode_exception);  $time = strtotime('6-8-2017 21:52:00');  $date = date('j-n-y h:i:s',$time);  $sql1  = "select top 100 * `$table_name $table_number` systeemtijd > `$date`";  $result = $dbh->query($sql1);  while($row = $result->fetch()) {       print_r($row); }

i'm able select records field in table (where value > 200 example) not based on date column in table. tried without `` and:

$sql1  = "select top 100 * `$table_name $table_number` systeemtijd > date `$date`";

all give error:

fatal error: uncaught exception 'pdoexception' message 'sqlstate[42000]: syntax error or access violation: 0 [microsoft][odbc microsoft access driver] syntax error (missing operator) in query expression 'systeemtijd > 6-8-2017 21:52:00'. (sqlprepare[0] @ ext\pdo_odbc\odbc_driver.c:206)' in c:\bitnami\wampstack-5.6.30-1\apache2\htdocs\php7\databuilt\larissa_connector\data_uploader.php:65 stack trace: #0 c:\bitnami\wampstack-5.6.30-1\apache2\htdocs\php7\databuilt\larissa_connector\data_uploader.php(65): pdo->query('select top 100 ...') #1 {main} thrown in c:\bitnami\wampstack-5.6.30-1\apache2\htdocs\php7\databuilt\larissa_connector\data_uploader.php on line 65

passing variables not idea, have aware of how correctly escape them, try using pdo::prepare:

/* execute prepared statement passing array of values */ $sql = "select top 100 * $full_table_name    systeemtijd  > :date"; $sth = $dbh->prepare($sql); $sth->execute(array(':date' => $date); $red = $sth->fetchall();

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
