sql server - Change tracking - sys_change_operation are all "I"? -

-

i created test table. 

create table test (id int not null, ......)    on [primary] (data_compression = page) go alter table test add primary key clustered (id)    (data_compression = page) on [primary] go create nonclustered index [ix_timestamp] on test ([timestamp])    (data_compression = page) on [primary] go alter table test enable change_tracking (track_columns_updated = on)

update: table has trigger writing pks of changes in table

and inserted values in table. updated 1 row using update test set ... id = 1.

however following query returns "i" sys_change_operation? can cause problem? (btw, tried enable cdc, doesn't capture anything.)

select distinct commit_time,sys_change_operation, count(*) -- select *     changetable(changes dbo.test, 0) c     join sys.dm_tran_commit_table tc on c.sys_change_version = tc.commit_ts group commit_time, sys_change_operation

results:

 commit_time             sys_change_operation count ----------------------- -------------------- ----------- 2014-05-29 22:39:22.397                    5944 2014-05-29 22:47:41.220                    1  (the last row should "u")

have @ excellent article here. explains why seeing behavior. issue 0 being passed argument changetable.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
