    <p>I have the following sql which returns Projects and related Contractors as well as document size info from three different tables. The sequence is: First Contractors are entered in the system, then Projects are entered for each Contractors, during with document sizes (sheets) are entered. So far so good: The following sql returns all projects along with appropriate Contractors and Sheets fine:</p> <pre><code>SELECT dbo.generalcontractors.name, dbo.Projects.*, dbo.sheets.sheetsize, dbo.sheets.sheetid FROM dbo.generalcontractors INNER JOIN dbo.Projects ON (dbo.generalcontractors.uid = dbo.Projects.generalcontractorid) INNER JOIN dbo.sheets ON (dbo.Projects.sheetid = dbo.sheets.sheetid) ORDER BY dbo.Projects.projectdate DESC </code></pre> <p>Now, what needs to happen is that documents for individual projects are entered in a <code>ProjectDocuments</code> table. I have the following code which checks to see documents exist in the <code>ProjectsDocuments</code> table and return appropriate values; currently, the project id is hard-coded and it work. </p> <p>Question is: how can I combine the following sql into the sql above? I am looking for one query result which will show any matching rows from the <code>ProjectsDocument</code> table and if no matching then will show 'Not Found'.</p> <p>This is for SQL Server 2005.</p> <p>Thanks!</p> <pre><code>IF (SELECT COUNT(*) FROM dbo.projectsdocuments, dbo.Projects WHERE projectsdocuments.projectid = Projects.projectid AND Projects.projectid = 5) &gt; 0 SELECT * FROM projectsdocuments ELSE SELECT 'Not Found' AS HighPrice </code></pre>

    1. CO@marc_s. Thanks. Too early for me to give this up. Any other way I can return all this in one query?

    2. COCan you please post "CREATE" statements for the tables in question? That way I can use SSMS to debug.

    3. COPer this: http://www.mssqltips.com/sqlservertip/1667/sql-server-join-example/ the RIGHT OUTER JOIN should work too. My current sql has this added: ' Right OUTER JOIN dbo.projectsdocuments ON (Select * from Projects) ' but getting an error: ' An expression of non-boolean type specified in a context where a condition is expected, near 'ORDER'. ' (see the ORDER in the original sql above). Thanks!

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.
