Rows are numbered starting from 1 in the order defined by the ORDER BY clause in the window definition, or in arbitrary order otherwise. So you can rewrite your query as follows: SELECT FROM (SELECT ROWNUMBER () OVER (ORDER BY ID) AS RN, COUNT () OVER () AS CNT, Id, Name, Phone FROM MyTable WHERE Deleted'F') T WHERE RN > 100 AND RN < 500 Share. rownumber() The number of the row within the current partition. The syntax for the count function in SQLite is: SELECT count(aggregateexpression) FROM. Instead, use PDO::query() to issue a SELECT.
