    <p>I've got a SQL query running a FULL JOIN on multiple database tables. The query is dynamic based on user input but for the example I just included some possible inputs.</p> <p>This issue I'm having is I need to filter by multiple date ranges and return the query results if they fall within either date range.</p> <p>The query as I have now is:</p> <pre><code>SELECT rank=COUNT(*) FROM [LOM].[dbo].[lom_problem] problem FULL JOIN [LOM].[dbo].[lom_batch] batch on problem.lom_number = batch.lom_number FULL JOIN [LOM].[dbo].[lom_specimen] specimen on problem.lom_number = specimen.lom_number FULL JOIN [LOM].[dbo].[Main_LOM_Form] main on problem.lom_number = main.lom_number WHERE problem.problem = '102' AND batch.batch IS NULL AND main.practice_code IN('HPMR', 'DOCTORs2') AND main.occurrence_date &gt;=Convert(datetime,'01/04/2012') AND main.occurrence_date &lt;= Convert(datetime,'01/05/2012') OR main.received_date&gt;=Convert(datetime,'01/04/2012') AND main.received_date &lt;= Convert(datetime,'01/05/2012') </code></pre> <p>However, the query returns the results as if my query was the SUM of </p> <pre><code>SELECT rank=COUNT(*) FROM [LOM].[dbo].[lom_problem] problem FULL JOIN [LOM].[dbo].[lom_batch] batch on problem.lom_number = batch.lom_number FULL JOIN [LOM].[dbo].[lom_specimen] specimen on problem.lom_number = specimen.lom_number FULL JOIN [LOM].[dbo].[Main_LOM_Form] main on problem.lom_number = main.lom_number WHERE problem.problem = '102' AND batch.batch IS NULL AND main.practice_code IN('HPMR', 'DOCTORs2') AND main.occurrence_date &gt;=Convert(datetime,'01/04/2012') AND main.occurrence_date &lt;= Convert(datetime,'01/05/2012') </code></pre> <p>and</p> <pre><code>SELECT rank=COUNT(*) FROM [LOM].[dbo].[lom_problem] problem FULL JOIN [LOM].[dbo].[lom_batch] batch on problem.lom_number = batch.lom_number FULL JOIN [LOM].[dbo].[lom_specimen] specimen on problem.lom_number = specimen.lom_number FULL JOIN [LOM].[dbo].[Main_LOM_Form] main on problem.lom_number = main.lom_number WHERE main.received_date&gt;=Convert(datetime,'01/04/2012') AND main.received_date &lt;= Convert(datetime,'01/05/2012') </code></pre> <p>How do I get the query to return the results with this part intact:</p> <pre><code>SELECT rank=COUNT(*) FROM [LOM].[dbo].[lom_problem] problem FULL JOIN [LOM].[dbo].[lom_batch] batch on problem.lom_number = batch.lom_number FULL JOIN [LOM].[dbo].[lom_specimen] specimen on problem.lom_number = specimen.lom_number FULL JOIN [LOM].[dbo].[Main_LOM_Form] main on problem.lom_number = main.lom_number WHERE problem.problem = '102' AND batch.batch IS NULL AND main.practice_code IN('HPMR', 'DOCTORs2') </code></pre> <p>plus the filtering for either date range on top of that:</p> <pre><code> AND main.occurrence_date &gt;=Convert(datetime,'01/04/2012') AND main.occurrence_date &lt;= Convert(datetime,'01/05/2012') OR main.received_date&gt;=Convert(datetime,'01/04/2012') AND main.received_date &lt;= Convert(datetime,'01/05/2012') </code></pre> <p>Thanks!</p> <p>Edit: I need to filter based on a data range of main.occurrence_date and main.received_date. If the data range is present in either one or the other column, I need to return the count. However, the query as I have now returns the sum of the first part of the where statement and then the results from the second part (after OR). I thought it may have been just a syntax/formatting issue but was unsure.</p>

    1. COCould you please make the question a bit more verbose? Also, is a FULL JOIN necessary, or would an INNER JOIN work?

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.
