PersistenceUtility.addSQLServerNativePagingSortingToQuery(String query,
PageControl pageControl)
Note: always put the rownum column at the END of the columns, so that code
which relies on index-based access to the result set data doesn't break
Method 1:
SELECT outerResults.* FROM (
SELECT innerResults.*,
ROW_NUMBER() OVER( {orderByClause} ) AS rownum
FROM ( {queryWithoutOrderBy} ) AS innerResults
) AS outerResults
WHERE rownum <= maxRowNum AND rownum >= minRowNum
The above method fails in circumstances where the orderByClause is built up with
aliases that aren't in the explicit select list returned from queryWithoutOrderBy
Method 2:
Fix above shortcomings by pushing the orderByClause into the actual select list
SELECT singleResults.* FROM (
{queryWithoutOrderBySelectList}
, ROW_NUMBER() OVER( {orderByClause} ) AS rownum
{queryWithoutOrderByRestOfQuery}
) AS singleResults
WHERE rownum <= maxRowNum AND rownum >= minRowNum
Actually, both of the above methods have small flaws. |
