unique integer key (the [rowid]) associated with every 
row of every table and so are not available on [WITHOUT ROWID] tables.
^The special identifiers only refer to the row key if the [CREATE TABLE]
statement does not define a real column with the same name.
^The rowid can be used anywhere a regular
column can be used.</p>

<h3>The EXISTS operator</h3>

<p>^The EXISTS operator always evaluates to one of the integer values 0 
and 1. ^If executing the SELECT statement specified as the right-hand 
operand of the EXISTS operator would return one or more rows, then the
EXISTS operator evaluates to 1. ^If executing the SELECT would return
no rows at all, then the EXISTS operator evaluates to 0.
