Parse SQL Transaction log in .NET

I want to parse transaction log file.

Actually, i need to trace out changes in my database.[either by insertion/updation/deletion of data or adding/modifiying object.] within my application.

I study SQL Profile. But it is limited for its run and also resource hunger or extra burden on server in case of large size database and busy server.

So please guide me. Also suggest be its appropriate solution.

Thanks.

You could create internal trace in SQL Profiler format for SQL Server. You could do it using sp:

sp_trace_create/sp_trace_setvent

May you guide little bit more or refer me any link for further guide... either parsing to transaction log or using any other mean.

Partitioned view doesn't allow to query itself while insertion

I created 2 similar tables for different accounts within one database and
partitioned view on them.
create table t
(
[ID] int identity(1,1),
[Name] varchar(15),
[Account] varchar(20) default 'Account1' check(Team = 'Account1'),
PRIMARY KEY CLUSTERED
(
[ID], [Account]
)
)
create view v
as
select * from Account1.t
union all
select * from Account2.t
I run query like this:
"select top 100 * from v where Account = 'Account1'"
and massive insertion from staging table like this at the same time:
"insert into t ( name ) select name from tt under different account"
my query stops until insertion is completed.
FYI: each tables reside in it's own filegroup. Each filgroup has its files
on physically different HDD.
There are 2 multithreaded processors there and parallelism works.
Execution plpan shows DIFFERENT CLUSTER KEYS ARE USED for any ss and so o
n.
Isolation level is Read Commited (when I set read uncommited it works
without locks, of course).
I don't know why my query wait for end of insertion. Query and insertion
don't use common resources. They MUST works independently...Can you cut and paste the exact SQL you're running, or provide
a repro without typos? What you posted here includes a CHECK
constraint that refers to a non-existent column named [Team].
You might try reversing the order of the primary key columns.
