    <p>I have an ERP system which I'm trying to debug and at some point when issuing a command from frontend a set of queries is executed in SQL Server.</p> <p>In the set of queries there is a <code>DELETE</code> statement that should execute and remove some records from a table, but for some reason those records are not removed.</p> <p>I have tried a few situations to figure out why this doesn't happen.</p> <ol> <li>I've tried locking the table with a large query issued both from a frontend command and from an explicit backend set of queries from SQL Server.</li> <li>I've tried to review user access to the table and that is correct.</li> <li>I've also taken into account problems with the network connection, but because there are more statements from the same set that have executed before/after this <code>DELETE</code> statement, I've kind of ruled this out. </li> </ol> <p>Is there anything else I could look at, or if you know of any possibility in which a <code>DELETE</code> statement does not execute?</p> <p>Any suggestion is helpful as I am trying to replicate the issue and I'm out of ideas. </p> <p><strong>UPDATE:</strong></p> <p>As per your request, this is the query</p> <pre><code>DELETE FROM Payments WHERE transactionID = 5005281 </code></pre> <p><strong>UPDATE 2</strong>:</p> <p>I've ran profiler when issuing the command from frontend so if a <code>DELETE</code> statement is present in the queries, then it was not supresed by application logic. Also, there are no calls to stored procedures to suspect the record is begin reinserted after DELETE.</p>

    1. COCheck which relationships are present in the database. If you have PK_FK couples, the delete won't work

    3. COAlso, you could `convert the DELETE query into a similar SELECT query with same filtering etc` and see if you get any results?

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.
