    <p>The pseudo is too cryptic (reduced?) It is very unlikely to get 2 columns per cross join of 2 tables in each of the union components</p> <pre><code>INSERT INTO T1(A,B) (SELECT * FROM E,R) UNION (SELECT * FROM Z,X) </code></pre> <p>Note: If you have ANY order by clause at all, it <em>must</em> be at the end of the union</p> <pre><code>INSERT T1(A,B) SELECT P,Q FROM E,R UNION SELECT R,S FROM Z,X </code></pre> <p><em>@updated based on error text "Server: Msg 104, Level 15, State 1, Line 1 ORDER BY items must appear in the select list if the statement contains a UNION operator"</em></p> <p>This occurs when you have a union that attempts to perform ORDER BY on a column that does not appear in the result. Consider a normal ORDER BY involving non-selected columns</p> <pre><code>select top 10 name from syscolumns order by xtype </code></pre> <p>The rows are consistent and the query can be satisfied. However, if you did</p> <pre><code>select top 10 name from syscolumns where xtype &gt; 50 union all select top 10 name from syscolumns where xtype &lt; 50 order by xtype </code></pre> <p>EVEN IF xtype exists in both parts of the UNION, but the time it gets presented to ORDER BY (which works at the END over the entire result set), the column is not there. You would have to rewrite it (if you didn't want to show <code>xtype</code>) as</p> <pre><code>select name from ( select top 10 name, xtype from syscolumns where xtype &gt; 50 union all select top 10 name, xtype from syscolumns where xtype &lt; 50 ) x order by xtype </code></pre> <p>Hope that helps</p>

    1. COI have put couple of joins like this which are not near UNION, as they are on joins, LEFT OUTER JOIN FS77..S_CONTACT_XM REQXM ON REQXM.PAR_ROW_ID = REQ.ROW_ID AND REQXM.TYPE = 'Contact Program' AND REQXM.ATTRIB_03 = 'Orencia Reimb Support Services' AND REQXM.ROW_ID = (SELECT TOP 1 ROW_ID FROM FS77..S_CONTACT_XM WHERE PAR_ROW_ID = REQ.ROW_ID AND TYPE = 'Contact Program' ORDER BY CREATED DESC) can it create a problem.. individual queries are working fine. should these be after WHERE clause.

    2. COThat should probably be INSERT INTO T1(A,B) SELECT * FROM E,R UNION (SELECT * FROM Z,X)

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.
