** that the query planner does not need the rows to be returned in sorted order
** as long as all rows with the same values in all columns identified by the

** This mode is used for a DISTINCT query.
** <li value="3"><p>
** ^(If the sqlite3_vtab_distinct() interface returns 3, that means the

** virtual table must return rows in the order defined by "aOrderBy" as
** if the sqlite3_vtab_distinct() interface had returned 0.  However if
** two or more rows in the result have the same values for all columns
** identified by "colUsed", then all but one such row may optionally be

** <p>The following table summarizes the conditions under which the
** virtual table is allowed to set the "orderByConsumed" flag based on
** the value returned by sqlite3_vtab_distinct().  This table is a
** restatement of the previous four paragraphs:
**
** <table border=1 cellspacing=0 cellpadding=10 width="90%">
** <tr>
** <td valign="top">sqlite3_vtab_distinct() return value
** <td valign="top">Rows are returned in aOrderBy order
** <td valign="top">Rows with the same value in all aOrderBy columns are adjacent
** <td valign="top">Duplicates over all colUsed columns may be omitted
** <tr><td>0<td>yes<td>yes<td>no
** <tr><td>1<td>no<td>yes<td>no
** <tr><td>2<td>no<td>yes<td>yes
** <tr><td>3<td>yes<td>yes<td>yes
** </table>
**
** ^For the purposes of comparing virtual table output values to see if the
** values are same value for sorting purposes, two NULL values are considered
** to be the same.  In other words, the comparison operator is "IS"
** (or "IS NOT DISTINCT FROM") and not "==".

** that the query planner does not need the rows to be returned in sorted order
** as long as all rows with the same values in all columns identified by the
** "aOrderBy" field are adjacent.)^  This mode is used when the query planner
** is doing a GROUP BY.
** <li value="2"><p>
** ^(If the sqlite3_vtab_distinct() interface returns 2, that means
** that the query planner does not need the rows returned in any particular

** The virtual table is not required to omit rows that are duplicates

** too much extra effort, it could potentially help the query to run faster.
** This mode is used for a DISTINCT query.
** <li value="3"><p>
** ^(If the sqlite3_vtab_distinct() interface returns 3, that means the

** virtual table must return rows in the order defined by "aOrderBy" as
** if the sqlite3_vtab_distinct() interface had returned 0.  However if
** two or more rows in the result have the same values for all columns
** identified by "colUsed", then all but one such row may optionally be

** <p>The following table summarizes the conditions under which the

** the value returned by sqlite3_vtab_distinct().  This table is a
** restatement of the previous four paragraphs:
**
** <table border=1 cellspacing=0 cellpadding=10 width="90%">
** <tr>
** <td valign="top">sqlite3_vtab_distinct() return value
** <td valign="top">Rows are returned in aOrderBy order
** <td valign="top">Rows with the same value in all aOrderBy columns are adjacent
** <td valign="top">Duplicates over all colUsed columns may be omitted
** <tr><td>0<td>yes<td>yes<td>no
** <tr><td>1<td>no<td>yes<td>no
** <tr><td>2<td>no<td>yes<td>yes
** <tr><td>3<td>yes<td>yes<td>yes
** </table>
**
** ^For the purposes of comparing virtual table output values to see if the
** values are same value for sorting purposes, two NULL values are considered
** to be the same.  In other words, the comparison operator is "IS"
** (or "IS NOT DISTINCT FROM") and not "==".
