php - "Executing SQL directly; no cursor" error when using SCOPE_IDENTITY/IDENT_CURRENT -

-

there wasn't on google error, i'm asking here. i'm switching php web application using mysql sql server 2008 (using odbc, not php_mssql). running queries or else isn't problem, when try scope_identity (or similar functions), error "executing sql directly; no cursor". i'm doing after insert, should still in scope. running same insert statement query insert id works fine in sql server management studio. here's code right (everything else in database wrapper class works fine other queries, i'll assume isn't relevant right now):

function insert_id(){     return $this->query_first("select scope_identity() insert_id"); }

query_first being function returns first result first field of query (basically equivalent of execute_scalar() on .net).

the full error message: warning: odbc_exec() [function.odbc-exec]: sql error: [microsoft][sql server native client 10.0][sql server]executing sql directly; no cursor., sql state 01000 in sqlexecdirect in c:[...]\database_mssql.php on line 110

you try using output clause work around:

insert yourtable         (col1, col2, col3)         output inserted.youridentitycol insert_id     values (val1, val2, val3)

this single statement insert row , return result set of identity values.

working sample:

create table yourtesttable (rowid int identity(1,1), rowvalue varchar(10)) go  insert yourtesttable         (rowvalue)         output inserted.rowid insert_id     values         ('abcd')

output: 

insert_id ----------- 1  (1 row(s) affected)

this if insert multiple rows @ 1 time:

insert yourtesttable         (rowvalue)         output inserted.rowid insert_id     select 'abcd'     union select '1234'     union select 'xyz'

output:

insert_id ----------- 2 3 4  (3 row(s) affected)

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
