| |
| <p>One important reason that RelRoot exists is to deal with queries like |
| |
| <blockquote><code>SELECT name |
| FROM emp |
| ORDER BY empno DESC</code></blockquote> |
| |
| <p>Calcite knows that the result must be sorted, but cannot represent its |
| sort order as a collation, because <code>empno</code> is not a field in the |
| result. |
| |
| <p>Instead we represent this as |
| |
| <blockquote><code>RelRoot: { |
| rel: Sort($1 DESC) |
| Project(name, empno) |
| TableScan(EMP) |
| fields: [0] |
| collation: [1 DESC] |
| }</code></blockquote> |
| |
| <p>Note that the <code>empno</code> field is present in the result, but the |
| <code>fields</code> mask tells the consumer to throw it away. |
| |
| <p>Another use case is queries like this: |
| |
| <blockquote><code>SELECT name AS n, name AS n2, empno AS n |
| FROM emp</code></blockquote> |
| |
| <p>The there are multiple uses of the <code>name</code> field. and there are |
| multiple columns aliased as <code>n</code>. You can represent this as |
| |
| <blockquote><code>RelRoot: { |
| rel: Project(name, empno) |
| TableScan(EMP) |
| fields: [(0, "n"), (0, "n2"), (1, "n")] |
| collation: [] |
| }</code></blockquote></div> |
