-** The most recently coded instruction was an OP_Column to retrieve the
-** i-th column of table pTab. This routine sets the P3 parameter of the
-** OP_Column to the default value, if any.
-**
-** The default value of a column is specified by a DEFAULT clause in the
-** column definition. This was either supplied by the user when the table
-** was created, or added later to the table definition by an ALTER TABLE
-** command. If the latter, then the row-records in the table btree on disk
-** may not contain a value for the column and the default value, taken
-** from the P3 parameter of the OP_Column instruction, is returned instead.
-** If the former, then all row-records are guaranteed to include a value
-** for the column and the P3 value is not required.
-**
-** Column definitions created by an ALTER TABLE command may only have
-** literal default values specified: a number, null or a string. (If a more
-** complicated default expression value was provided, it is evaluated
-** when the ALTER TABLE is executed and one of the literal values written
-** into the sqlite_master table.)
-**
-** Therefore, the P3 parameter is only required if the default value for
-** the column is a literal number, string or null. The sqlite3ValueFromExpr()
-** function is capable of transforming these types of expressions into
-** sqlite3_value objects.
