   * Defines the set of standard SQL row-level functions and

   *
   * <p>The standard set of row-level functions and operators are declared in
   * class {@link org.apache.calcite.sql.fun.SqlStdOperatorTable}. Anonymous inner
   * classes within that table are allowed only for specifying an operator's test
   * function; if other custom code is needed for an operator, it should be
   * implemented in a top-level class within this package instead.  Operators
   * which are not row-level (e.g. select and join) should be defined in package
   * {@link org.apache.calcite.sql} instead.
