    <p>I have this two tables:</p> <p>Table A</p> <pre> ID TYPE SDATE EDATE RATING 1 M 1/1/2010 1/1/2011 A 1 M 1/3/2010 1/4/2011 B 2 A 7/2/2010 1/31/2015 C 3 M 3/1/2011 1/20/2012 B 4 A 3/1/2011 1/20/2012 B 5 M 3/1/2009 3/1/2009 F 6 M 12/31/2006 12/31/9999 A 7 A 1/1/2006 12/31/9999 B </pre> <p>Table B</p> <pre> ID TYPE SDATE EDATE RATING 1 M 1/1/2010 1/1/2011 A 2 A 7/2/2010 1/31/2015 C 2 A 9/2/2010 1/31/2015 C 3 M 3/1/2011 1/20/2012 B 4 A 3/1/2011 1/20/2012 C 6 M 12/31/2006 12/31/2015 A 7 A 2/1/2006 12/31/9999 B 8 M 1/2/2010 1/2/2012 </pre> <p>When I perform a table A minus table B, it gets me the next result:</p> <pre> ID TYPE SDATE EDATE RATING 1 M 1/3/2010 1/4/2011 B 4 A 3/1/2011 1/20/2012 B 5 M 3/1/2009 3/1/2009 F 6 M 12/31/2006 12/31/9999 A 7 A 1/1/2006 12/31/9999 B </pre> <p>I have already identified the case where A.id is not in B.id, but how do I check when it is different in some other column?</p> <p>I'm not allowed to create anything on the schema, so I have to do it through queries.</p> <p>So far, this is what I have, but it gives me data that is not correct.</p> <pre> <code> with aminusb as ( select * from A minus select * from B ) select diff.* from aminusb diff ,B where diff.id = B.id and diff.start_date = B.start_date and diff.end_date = B.end_date and diff.rating &lt;&gt; B.rating </code> </pre> <p>Do you know how could I get the different scenarios?</p> <ul> <li>When everything is equal but, rating.</li> <li>When everything is equal but, end date.</li> <li>When nothing is equal but, it has the same id.</li> </ul> <p>I need to get a list of the records that fulfill every scenario so people can check it on detail.</p> <p>Thanks.</p>

    1. COYou might try [unpivoting](http://www.oracle-base.com/articles/11g/pivot-and-unpivot-operators-11gr1.php) A-B and B-A, join the results on ID and ColumnName and filter out ones having the same Value. After that you will have a list of differences by columns.

    2. CO@NikolaMarkovinović Hi, I tried with something like this, but it seems that it doesn't work for oracle 10g. `with aminusb as ( SELECT * FROM A MINUS SELECT * FROM B ) select diff from aminusb diff,B where diff.id = B.id and diff.start_date = B.start_date and diff.end_date = B.end_date and diff.rating <> B.rating unpivot ( rating_cd for as in ( SELECT DISTINCT (id) FROM A ) )`

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.
