    <p>I have a select statement that gets 4 column values in a row for one iteration from a query that has lot of joins. One of the column value has to be given to another select statement as input to check a where condition. This select statement returns three rows for a input from each iteration of the first select statement. I need to get all the column values from the three rows of the second select statement along with the all the column values of the first select statement.</p> <pre><code>SELECT val1, val2, val3, val4 from .... SELECT val5, val6 from anotherTable where someColumn = val1 </code></pre> <p>RESULT required :</p> <pre><code>val1, val2, val3, val4, val51, val61, val52, val62, val53, val63 </code></pre> <p>I, am using two connections and two readers to make this happen, but its slowing me down. I'd like it if I can get this done in a single stored procedure.</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.
