** Each SQL table is represented in memory by an instance of the
** following structure.
**
** Table.zName is the name of the table. The case of the original
** CREATE TABLE statement is stored, but case is not significant for
** comparisons.
**
** Table.nCol is the number of columns in this table. Table.aCol is a
** pointer to an array of Column structures, one for each column.
**
** If the table has an INTEGER PRIMARY KEY, then Table.iPKey is the index of
** the column that is that key. Otherwise Table.iPKey is negative. Note
** that the datatype of the PRIMARY KEY must be INTEGER for this field to
** be set. An INTEGER PRIMARY KEY is used as the rowid for each row of
** the table. If a table has no INTEGER PRIMARY KEY, then a random rowid
** is generated for each row of the table. TF_HasPrimaryKey is set if
** the table has any PRIMARY KEY, INTEGER or otherwise.
**
** Table.tnum is the page number for the root BTree page of the table in the
** database file. If Table.iDb is the index of the database table backend
** in sqlite.aDb[]. 0 is for the main database and 1 is for the file that
** holds temporary tables and indices. If TF_Ephemeral is set
** then the table is stored in a file that is automatically deleted
** when the VDBE cursor to the table is closed. In this case Table.tnum
** refers VDBE cursor number that holds the table open, not to the root
** page number. Transient tables are used to hold the results of a
** sub-query that appears instead of a real table name in the FROM clause
** of a SELECT statement.
** The schema for each SQL table and view is represented in memory
** by an instance of the following structure.
