** Turn the pExpr expression into an alias for the iCol-th column of the

**
** If the result set column is a simple column reference, then this routine
** makes an exact copy.  But for any other kind of expression, this
** routine make a copy of the result set column as the argument to the
** TK_AS operator.  The TK_AS operator causes the expression to be
** evaluated just once and then reused for each alias.
**
** The reason for suppressing the TK_AS term when the expression is a simple
** column reference is so that the column reference will be recognized as
** usable by indices within the WHERE clause processing logic. 
**
** The TK_AS operator is inhibited if zType[0]=='G'.  This means
** that in a GROUP BY clause, the expression is evaluated twice.  Hence:
**
**     SELECT random()%5 AS x, count(*) FROM tab GROUP BY x
**
** Is equivalent to:
**
**     SELECT random()%5 AS x, count(*) FROM tab GROUP BY random()%5
**
** The result of random()%5 in the GROUP BY clause is probably different
** from the result in the result-set.  On the other hand Standard SQL does
** not allow the GROUP BY clause to contain references to result-set columns.
** So this should never come up in well-formed queries.
**
** If the reference is followed by a COLLATE operator, then make sure
** the COLLATE operator is preserved.  For example:
**
**     SELECT a+b, c+d FROM t1 ORDER BY 1 COLLATE nocase;

** The order of the columns in the data_% table does not matter.

** If the target database table is a virtual table or a table that has no
** PRIMARY KEY declaration, the data_% table must also contain a column 
** named "rbu_rowid". This column is mapped to the tables implicit primary 
** key column - "rowid". Virtual tables for which the "rowid" column does

................................................................................
** For example, this row:

**
**   UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4;








**
** If the target database table is a virtual table or a table with no PRIMARY
** KEY, the rbu_control value should not include a character corresponding 
** to the rbu_rowid value. For example, this:
**
**   INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control) 
**       VALUES(NULL, 'usa', 12, '.x');
