Hi...
Help me understand what data structure this is? Ruby ODBC almost always
returns an ArrayOfArrays, but this is very very weird and I don't understand
what I'm seeing. (btw, google groups access to comp.lang.ruby is down)
indexes = @conn.indexes('tablename')
indexes.each do |ind|
puts ind[5]
end
=>nil
PK_indexname
XY_indexname2
indexes.each do |ind|
puts ind[5]
puts "hah"
end
=>nil
hah
PK_indexname
hah
XY_indexname2
hah
indexes.each do |ind|
puts ind[5][1]
end
=>foo_index.rb:122: undefined method `[]' for nil:NilClass (NoMethodError)
