sql server - Fully separating data manupulation logic in SQL in order to increase performance -


i've come across idea separation of data manipulation logic in sql code result in performance gain, i'm unsure extent true , reason i'm posting question.

assuming have database (let's small gallery) in have galleries, photos, , tags. each photo can member of many galleries, , each photo or gallery can have many tags. create single stored procedure handling photo , gallery management (i.e. photocreateorupdate) can accepts array of galleries (in serialized text, i.e. gallerya:info:tag1|tag2), photo information, same photo tags, , array galleries or tags deleted when updating record. if gallery exists, relations added, else created, , same tags , other things.

i've decided instead of relying on entity framework because believe way can send 1 request database web-end , can result performance gain avoid lot of foreach loops , joins can done faster.

however, when deserialzing formatted texts, have use cursors few times equal loops when using entity framework.

i think advantage of approach segregate concerns own context , keep asp.net code clean.

i want know extent assumptions true , point of question.

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 <...
