| <a href="MultiJoin.html" title="class in org.apache.calcite.rel.rules"><code>MultiJoin</code></a> and beneath a |
| <a href="../logical/LogicalJoin.html" title="class in org.apache.calcite.rel.logical"><code>LogicalJoin</code></a> so the |
| <a href="../logical/LogicalProject.html" title="class in org.apache.calcite.rel.logical"><code>LogicalProject</code></a> appears above the |
| <a href="../logical/LogicalJoin.html" title="class in org.apache.calcite.rel.logical"><code>LogicalJoin</code></a>. |
| |
| <p>In the process of doing |
| so, also save away information about the respective fields that are |
| referenced in the expressions in the |
| <a href="../logical/LogicalProject.html" title="class in org.apache.calcite.rel.logical"><code>LogicalProject</code></a> we're pulling up, as |
| well as the join condition, in the resultant <a href="MultiJoin.html" title="class in org.apache.calcite.rel.rules"><code>MultiJoin</code></a>s |
| |
| <p>For example, if we have the following sub-query: |
| |
| <blockquote><pre> |
| (select X.x1, Y.y1 from X, Y |
| where X.x2 = Y.y2 and X.x3 = 1 and Y.y3 = 2)</pre></blockquote> |
| |
| <p>The <a href="MultiJoin.html" title="class in org.apache.calcite.rel.rules"><code>MultiJoin</code></a> associated with (X, Y) associates x1 with X and |
| y1 with Y. Although x3 and y3 need to be read due to the filters, they are |
| not required after the row scan has completed and therefore are not saved. |
| The join fields, x2 and y2, are also tracked separately. |
| |
| <p>Note that by only pulling up projects that are on top of |
| <a href="MultiJoin.html" title="class in org.apache.calcite.rel.rules"><code>MultiJoin</code></a>s, we preserve projections on top of row scans. |
| |
| <p>See the superclass for details on restrictions regarding which |
| <a href="../logical/LogicalProject.html" title="class in org.apache.calcite.rel.logical"><code>LogicalProject</code></a>s cannot be pulled.</div> |
