Julia: Dict类型 与 Symbol

在SQLite库中,有时侯Insert 时,需要用到Dict{Symbol,Any}类型.

一般地,

julia> Dict(:a=>0,:b=>0)
Dict{Symbol,Int64} with 2 entries:
  :a => 0
  :b => 0

julia> Dict(:a=>0,Int64} with 2 entries:
  :a => 0
  :b => 0

看看其它变化,:b=>0.1) Dict{Symbol,Any} with 2 entries: :a => 0 :b => 0.1 julia> Dict(:a=>0,:b=>0.1,:c=>"c") Dict{Symbol,Any} with 3 entries: :c => "c" :a => 0 :b => 0.1

一般正常地,

julia> Dict("a"=>0.1,"b"=>"c")
Dict{ASCIIString,Any} with 2 entries:
  "b" => "c"
  "a" => 0.1
