    <p>You don't mention how the name is involved, so I'm assuming that you want this done by name. I'm going to further assume that when you talk about "consecutive" that you mean in date order, not in id order. Finally, I'm also going to assume that you would also exclude 5 zeroes in a row, 6 zeroes in a row, etc.</p> <p>There may be a simpler way, but this should work: </p> <pre><code>;WITH Transitions_To_CTE AS ( SELECT T1.id, T1.name, T1.date, T1.value FROM My_Table T1 LEFT OUTER JOIN My_Table T2 ON T2.name = T1.name AND T2.date &lt; T1.date AND T2.value &lt;&gt; 0 LEFT OUTER JOIN My_Table T3 ON T3.name = T1.name AND T3.date &gt; COALESCE(T2.date, '1900-01-01') AND T3.date &lt; T1.date WHERE T1.value = 0 AND T3.id IS NULL ), Transitions_From_CTE AS ( SELECT T1.id, T1.name, T1.date, T1.value FROM My_Table T1 LEFT OUTER JOIN My_Table T2 ON T2.name = T1.name AND T2.date &gt; T1.date AND T2.value &lt;&gt; 0 LEFT OUTER JOIN My_Table T3 ON T3.name = T1.name AND T3.date &lt; COALESCE(T2.date, '9999-12-31') AND T3.date &gt; T1.date WHERE T1.value = 0 AND T3.id IS NULL ), Range_Exclusions AS ( SELECT S.name, S.date AS start_date, E.date AS end_date FROM Transitions_To_CTE S INNER JOIN Transitions_From_CTE E ON E.name = S.name AND E.date &gt; S.date LEFT OUTER JOIN Transitions_From_CTE E2 ON E2.name = S.name AND E2.date &gt; S.date AND E2.date &lt; E.date WHERE E2.id IS NULL AND (SELECT COUNT(*) FROM dbo.My_Table T WHERE T.name = S.name AND T.date BETWEEN S.date AND E.date) &gt;= 4 ) SELECT T.id, T.name, T.date, T.value FROM dbo.My_Table T WHERE NOT EXISTS (SELECT * FROM Range_Exclusions RE WHERE RE.name = T.name AND T.date BETWEEN RE.start_date AND RE.end_date) </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
