Retrieving the text of a query

    I would like to write a trigger that captures the text of a query against a table and insert it into an audit table.  So when an update executes against a user table, I want the actual SQL statement.

    Is there a system variable/sproc/function that captures this?

    If not, has anyone done this another way?

    Start a trace with the profiler that checks the the words update and the table name. Make sure it inserts into a table and you're good to go.

    Can't use profiler.  This has to be done within a trigger.

    Not gonna happen with anything else than a trace or s shitload of recoding.

    I have never tried this but here is a thought

    You can run dbcc inputbuffer (@@SPID) to read the buffer contents. Not sure if that will help you though. Keep in mind that there is a limit of 255 chars on the string and if the update happens through RPC only the procname is avilable

    This is probably best done with log reader tools but is not going to be cheap

    You can try some server side tracing, (not using profile)

    But I do not think the work can be done in a trigger.

    I was hoping not to have to use tracing (because of the pitfalls with profiler) but this could be a good solution.

    Have you used this to just capture the query text?
