php - How can I execute native queries in my Model? -


i have requirement define composite foreign keys in model.looks not supported currently. so, try run native queries in model.

i have 2 tables(vwalarm, vwyfusertositemappings) both has 2 columns.

companyid,sitecode

i want return single row, joining both columns 2 tables.

here model;

class alarm extends model {      protected $table = 'vwalarm';     protected $primarykey = 'alarmid';  ..   public function site()     {         $rec = \db::table('vwalarm')             ->join('vwyfusertositemappings', 'vwalarm.sitecode', '=', 'vwyfusertositemappings.sitecode')             ->join('vwyfusertositemappings','vwalarm.companyid', '=', 'vwyfusertositemappings.companyid')             ->first();          return $rec; }

im getting 

 queryexception sqlstate[42000]: [microsoft][odbc driver 13 sql server][sql server]the objects "vwyfusertositemappings" , "vwyfusertositemappings" in clause have same exposed names. use correlation names distinguish them. (sql: select top 1 * [vwalarm] inner join [vwyfusertositemappings] on [vwalarm].[sitecode] = [vwyfusertositemappings].[sitecode] inner join [vwyfusertositemappings] on [vwalarm].[companyid] = [vwyfusertositemappings].[companyid])

how can correct query?

set alias name table name below 

$rec = \db::table('vwalarm')             ->join('vwyfusertositemappings vw1', 'vwalarm.sitecode', '=', 'vw1.sitecode')             ->join('vwyfusertositemappings vw2','vwalarm.companyid', '=', 'vw2.companyid')             ->first();

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
