| <div class="block">RelStructuredTypeFlattener removes all structured types from a tree of |
| relational expressions. Because it must operate globally on the tree, it is |
| implemented as an explicit self-contained rewrite operation instead of via |
| normal optimizer rules. This approach has the benefit that real optimizer and |
| codegen rules never have to deal with structured types. |
| |
| <p>As an example, suppose we have a structured type <code>ST(A1 smallint, A2 |
| bigint)</code>, a table <code>T(c1 ST, c2 double)</code>, and a query <code> |
| select t.c2, t.c1.a2 from t</code>. After SqlToRelConverter executes, the |
| unflattened tree looks like: |
| |
| <blockquote><pre><code> |
| LogicalProject(C2=[$1], A2=[$0.A2]) |
| LogicalTableScan(table=[T]) |
| </code></pre></blockquote> |
| |
| <p>After flattening, the resulting tree looks like |
| |
| <blockquote><pre><code> |
| LogicalProject(C2=[$3], A2=[$2]) |
| FtrsIndexScanRel(table=[T], index=[clustered]) |
| </code></pre></blockquote> |
| |
| <p>The index scan produces a flattened row type <code>(boolean, smallint, |
| bigint, double)</code> (the boolean is a null indicator for c1), and the |
| projection picks out the desired attributes (omitting <code>$0</code> and |
| <code>$1</code> altogether). After optimization, the projection might be |
| pushed down into the index scan, resulting in a final tree like |
| |
| <blockquote><pre><code> |
| FtrsIndexScanRel(table=[T], index=[clustered], projection=[3, 2]) |
| </code></pre></blockquote></div> |
