    <p>SQL 2008</p> <p>Basically i have a dataset that looks like this:</p> <pre><code>AcctID AcctType AcctSubType Curr TransType Amount Sequence 1 CCY SET EUR Opening 1000 B 1 CCY SET EUR BUY -100 T 1 CCY SET EUR SEL 100 T 1 CCY SET EUR Closing 1000 B 2 CCY SET EUR Opening 2000 B 2 CCY SET EUR SEL 100 T 2 CCY SET EUR Closing 2100 B 3 CCY INC EUR Opening 1000 B 3 CCY INC EUR SEL 200 T 3 CCY INC EUR BUY -100 T 3 CCY INC EUR Closing 1100 B 4 CCY SET GBP Opening 2000 B 4 CCY SET GBP SEL 100 T 4 CCY SET GBP Closing 2100 B </code></pre> <p>What i want to do is return all from the dataset where there are more than one capital account per currency (so basically more than one distinct AcctID). A capital account is identified by AcctType = 'CCY' and AcctSubType = 'SET'. Also i only want the balances, so where Sequence = 'B'.</p> <p>So for the above dataset what would be returned is the following:</p> <pre><code>AcctID AcctType AcctSubType Curr TransType Amount Sequence 1 CCY SET EUR Opening 1000 B 1 CCY SET EUR Closing 1000 B 2 CCY SET EUR Opening 2000 B 2 CCY SET EUR Closing 2100 B </code></pre> <p>I started off like this, but got confused how to include the distinct count of AcctID within a currency is greater than 1:</p> <pre><code>;;with test (AcctID, AcctType, AcctSubType, Curr, TransType, Amount, Sequence) as ( select 1, 'CCY', 'SET', 'EUR', 'Opening', 1000, 'B' union all select 1, 'CCY', 'SET', 'EUR', 'BUY', -100, 'T' union all select 1, 'CCY', 'SET', 'EUR', 'SEL', 100, 'T' union all select 1, 'CCY', 'SET', 'EUR', 'Closing', 1000, 'B' union all select 2, 'CCY', 'SET', 'EUR', 'Opening', 2000, 'B' union all select 2, 'CCY', 'SET', 'EUR', 'SEL', 100, 'T' union all select 2, 'CCY', 'SET', 'EUR', 'Closing', 2100, 'B' union all select 3, 'CCY', 'INC', 'EUR', 'Opening', 1000, 'B' union all select 3, 'CCY', 'INC', 'EUR', 'SEL', 200, 'T' union all select 3, 'CCY', 'INC', 'EUR', 'BUY', -100, 'T' union all select 3, 'CCY', 'INC', 'EUR', 'Closing', 1100, 'B' union all select 4, 'CCY', 'SET', 'GBP', 'Opening', 2000, 'B' union all select 4, 'CCY', 'SET', 'GBP', 'SEL', 100, 'T' union all select 4, 'CCY', 'SET', 'GBP', 'Closing', 2100, 'B' ) select * from test t where t.AcctType = 'CCY' and t.AcctSubType = 'SET' and t.Sequence = 'B' and t.Curr in (select w.Curr from test w where w.AcctType = 'CCY' and w.AcctSubType = 'SET' and w.Sequence = 'B' group by w.Curr having COUNT(distinct w.AcctID) &gt; 1) </code></pre> <p>Now this works for the dataset, although what concerned me is would this work if there was more than one currency with more than one capital account? Does the code i've created work for what i want to achieve.</p> <p>Many Thanks</p>

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.
