    <p>If I understand your question correctly, the code below should work. Note that I've created a function to help with the string concatenation. I'm not sure if you wanted to AND or OR your conditions. I've used AND in my sample. You can easily adjust it for OR if that's appropriate.</p> <pre><code>/* Set up sample data */ create table FilterData ( CategoryID char(4), ColumnID char(3), AnswerCode char(2) ) insert into FilterData (CategoryID, ColumnID, AnswerCode) values ('0349','Q15','02') insert into FilterData (CategoryID, ColumnID, AnswerCode) values ('0349','Q15','03') insert into FilterData (CategoryID, ColumnID, AnswerCode) values ('0349','Q16','04') go /* Helper function to concatenate all AnswerCodes for a given ColumnID */ create function dbo.fnStringAnswerCodes(@ColumnID char(3)) returns varchar(1000) as begin declare @CodeString varchar(1000) set @CodeString = @ColumnID + ' in (' select @CodeString = @CodeString + '''' + AnswerCode + ''',' from FilterData where ColumnID = @ColumnID /* Remove trailing comma and add closing parens */ select @CodeString = left(@CodeString, len(@CodeString)-1) + ')' return @CodeString end go declare @CategoryID char(4) declare @SQLString varchar(1000) declare @WhereClause varchar(1000) set @CategoryID = '0349' set @SQLString = 'select * from TransactionData ' set @WhereClause = 'where CategoryID=''' + @CategoryID + ''' and ' select @WhereClause = @WhereClause + dbo.fnStringAnswerCodes(ColumnID) + ' and ' from FilterData where CategoryID = @CategoryID group by ColumnID /* Remove Trailing 'AND' */ set @WhereClause = LEFT(@WhereClause, len(@WhereClause)-3) set @SQLString = @SQLString + @WhereClause select @SQLString /* Last step would be to dynamically execute the string we built */ /* exec sp_ExecuteSQL @SQLString */ /* Clean Up */ drop function dbo.fnStringAnswerCodes drop table FilterData </code></pre>

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.
