question related to sqldataadapter.

[archana]

hi all

I have some doubts related to database handling in .net.

I am using sqldataadapter to update and insert rows into database.

What i want to know is at a time of inserting rows using
sqlqueryanalyser, is their any locking system used internally.

if yes what it is.

any help will be truely appreciated.

thanks in advance.

I assume you mean SqlDataAdapter vs "SQLQueryAnalyzer" in the last part of
your post.

I am not aware of any specific locking mechanism in using the Update method
of a SQLDataAdapter. If you are concerned about concurrency issues, one
solution is to use a timestamp (in SQL Server, "rowversion") column and
include this in the WHERE clause of your insert or update query / stored
proc. Then you can examine the RowErrors and other properties after the
update to see which rows were not inserted / updated.
Hope that helps.
