    <p>I have implemented <code>SqlTransaction</code> in c# to begin, commit and rollback transaction. Everything is going right, but I've got some problem while accessing those tables which are in connection during transaction. I was not able to read table during the transaction(those table which are in transaction). While searching about this, I found that it happens due to an exclusive lock. Any subsequent selects on that data in turn have to wait for the exclusive lock to be released. Then, I have gone through every isolation level provided by <code>SqlTransaction</code>, but it did not work. So, I need to release exclusive lock during transaction so that other user can have access on that table and can read the data. Is there any method to achieve this? Thanks in advance.</p> <p>Here's my c# code for the transaction </p> <pre><code>try { SqlTransaction transaction = null; using (SqlConnection connection=new SqlConnection(Connection.ConnectionString)) { connection.Open(); transaction=connection.BeginTransaction(IsolationLevel.Snapshot,"FaresheetTransaction"); //Here all transaction occurs if (transaction.Connection != null) { transaction.Commit(); transaction.Dispose(); } } } catch (Exception ex) { if (transaction.Connection != null) transaction.Rollback(); transaction.Dispose(); } ` </code></pre> <p>This code is working fine, but the problem is that when I access the data of tables (those accessed during the transaction) during the time of transaction. The tables are being accessed by other parts of the application. So, when I tried to read data from the table, it throws an exception.</p>

    1. COWhat is your intention here? No not take the lock when updating? or for other readers to ignore the locks? (which are there for very good reasons)

    2. COI do not want to have lock in transacted table for other users....the transaction can go for long duration because at the time of transaction, ten of thousands data inserts into the table so it probably takes long time...So, at period of transaction, I want other user to have access on that table and can read data.......

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
