counting the inserts and updates on a table in a sql server database

[Viswanatha Thalakola]

Hello,

Can someone point me to getting the total number of inserts and updates on a table
over a period of time?

I just want to measure the insert and update activity on the tables.

Thanks.

On a single statement you can capture the @@rowcount into a variable and
write it to a log table. But if I'm reading this correctly, you don't want
to do this through the existing code base. Inserts are usually easy if
there is a primary or unique key. Assuming no deletes, simply how many new
keys are there since the last count. Or if the key is incrementing by one
what's the max value - the previous max value. Updates are more vague. How
many rows were updated or how many updates occurred These activities are
usually accommodated for in the initial table design with flag and
last_mod_date columns. Without auditing written into every piece of code or
proper schema design it's an ugly intensive task to rub to data sets
together (using checksums or straight comparisons) to find differences.

Hi Vish,

The easiest way to do this is to add some counting logic to the stored
procedures that do the inserting, updating and deleting. But if you can't
or won't change those tables (or if you allow direct data modifications,
without using stored procedures), you have two other options:

1. Set up a profiler trace. Catch the trace results in a table or in a
file, then use either SQL queries (if in a table) or text manipulation
tools (if in a file) to count the number of inserts, updates, etc. I must
add that I don't know the exact format and I'm not sure either if the
number of rows affected is included in the trace data (it it isn't, you
can't use this approach).

2. Create triggers for each table you need to monitor. Have these triggers
copy @@rowcount in a local variable as the first statement (that yields
the number of rows affected by the statement that fired the trigger) and
save that value to a table.

Best, Hugo

It isn't, but you can catch number of page writes. Still, though, not a
wholly reliable number.

Then again, I assume that the aim is not to save exact numbers, but get
some approxamite statistics, so some Profiler method is proably better
than adding triggers to the system.
