Linq Nested Inner Joins -


i want join following tables

1. b_book[1st table] -b_bid (book id)(pk) -b_name -b_categroyid (fk) 2. bi_bookinstance [2nd table] -bi_iid(instance id) -bi_bid (fk) -bi_price 3. bc_bookcategory [3rd table] -bc_categoryid (pk) -bc_categoryname

first join b_book , bi_bookinstance join result of both bookcategory. (1st join)[b_bid equals bi_bid] (2nd nested join)[result of 1st join b_categoryid equals bc_categoryid]

edit

sql following:

select * (select * b_book b join bi_bookinstance bi on b.b_bid = bi.bi_bid) t1 join bc_bookcategoryid bc on bc.bc_categoryid = t1.b_categoryid

what matches query in linq following (and you'll notice similarity sql). i've included examples on how rename fields returned, such price or categoryname:

var results = b in b_book join bi in bi_bookinstance on b.b_bid equals bi.bi_bid join bc in bc_bookcategory on b.b_categoryid equals bc.bc_categoryid select new { // put in whatever fields want returned here: b.b_bid, b.b_categoryid, b.b_name, bi.bi_bid, bi.bi_iid, price = bi.bi_price, bc.bc_categoryid, categoryname = bc.bc_categoryname };

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
