  name of the index and <b>tbl_name</b> is the name of the table to which
  the index belongs.  For both tables and indices, the <b>sql</b> field is
  the text of the original CREATE TABLE or CREATE INDEX statement that
  created the table or index.  For automatically created indices (used
  to implement the PRIMARY KEY or UNIQUE constraints) the <b>sql</b> field
  is NULL.</p>

  <p>The SQLITE_MASTER table is read-only.  You cannot change this table


  using UPDATE, INSERT, or DELETE.  The table is automatically updated by
  CREATE TABLE, CREATE INDEX, DROP TABLE, and DROP INDEX commands.</p>

  <p>Temporary tables do not appear in the SQLITE_MASTER table.  Temporary
  tables and their indices and triggers occur in another special table
  named SQLITE_TEMP_MASTER.  SQLITE_TEMP_MASTER works just like SQLITE_MASTER
  except that it is only visible to the application that created the 
  temporary tables.  To get a list of all tables, both permanent and
  temporary, one can use a command similar to the following:
