  <p>The standard set of row-level functions and operators are declared in
  class <a href="../../../../../org/apache/calcite/sql/fun/SqlStdOperatorTable.html" title="class in org.apache.calcite.sql.fun"><code>SqlStdOperatorTable</code></a>. Anonymous inner

  which are not row-level (e.g. select and join) should be defined in package
