So at what point does your app learn the structure of the SQL table?
At the moment I know the structure after executing the SQL and fetching
the first row [a ruby hash]. But the field set will change from SQL to
SQL, and Ferret is doing all the field specification for me via
hash-as-doc, ala.
def create
@index = Ferret::Index::Index.new()
conn = ODBC.connect(@odbc[:dsn], @odbc[:uid], @odbc[:pwd])
@sqls.each do |sql|
stmt = conn.prepare(sql)
stmt.execute.each_hash{ |row| @index << row }
stmt.close
stmt.drop
end
conn.disconnect
end
The field definitions do not change though, so I’m happy as long as the
hash-as-doc support remains in Ferret.
Cheers,
Neville
