    <p>I am working on SQL Server 2008 R2. I have two tables let us say <code>TblGroup</code> and <code>TblComplatedDetails</code>. </p> <p>TblGroup contains the name of Groups along with <code>MemberId</code> and <code>GroupType (i.e. in Daily, Weekly, Start, End)</code> and <code>TblComplatedDetails</code> contains <code>GroupId (i.e. foreign key of TblGroup)</code> along with completed datetime. Now I want all the group of specific <code>MemberId</code> except <code>GroupType="End"</code> AND "Start" type of Group only if it has no record in TblCompletedDetails. So the record set is something like below : </p> <pre><code>TblGroup ================================== Id MemberId GroupType ================================== 1 1 Daily 2 2 Daily 3 3 Daily 4 1 Weekly 5 1 Start 6 2 Weekly 7 2 Start 8 2 End 9 1 End 10 1 End TblCompletedDetails ====================================== Id GroupId CompletedDate ====================================== 1 1 xxxxxxxxxxxxxx 2 2 xxxxxxxxxxxxxx 3 3 xxxxxxxxxxxxxx 4 4 xxxxxxxxxxxxxx 5 1 xxxxxxxxxxxxxx 6 2 xxxxxxxxxxxxxx 7 3 xxxxxxxxxxxxxx 8 5 xxxxxxxxxxxxxx 9 6 xxxxxxxxxxxxxx </code></pre> <p>So for MemberId = 1 the desired Groups can be :</p> <pre><code>======= GroupId ======= 1 4 </code></pre> <p>But for MemberId = 2 the desired resule is : </p> <pre><code>======= GroupId ======= 2 6 7 </code></pre> <p>Because 7 is a "Start" type of Group that has not foreign key in TblCompletedDetails. Can anyone have idea? Awaiting for your valuable response.</p>

    1. COcondition you might need to use **TblGroup grp** 1. **grp.GroupType not in ('End')** 2. **grp.GroupType = 'Start' and (select count(*) from TblCompletedDetails tcd where grp.GroupId = tcd.GroupId)**

    2. CO@NaveenBabu In that case I will only get the records that are of "start" type of group only. I want all the type of groups except with type "End" and for "start" type of group there must not be the record in TblCompledDetails.

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.
