Question

how can i put my looped value to an array if i have this code?

local data = {
 for row in db:nrows("SELECT song.id, song.title as title, artist.name as name FROM song, artist where song.artist_id = artist.id") do
    {
     song = row.title,
     artist = row.name
    }
  end
}

but i got this error:

unexpected symbol near 'for'

i just wanted to be look like this…

   song = "HI",
   artist = "Tom"
 }
 {
   song = "Hello",
   artist = "mike"
 }
...
}

can anyone can help me about my situation or give some advice about it?
thanks in advance

Answer 1

You would have to do something like this, I think:

result = db:nrows("SELECT song.id, song.title as title, artist.name as name FROM song, artist where song.artist_id = artist.id")

data = {}
for i, row in ipairs(result) do
  data[i] = {}
  data[i].song = row.title
  data[i].artist = row.name
end

Edit: A question though: Why don’t you just specify that in the SQL query and use the results as is? I.e.:

data = db:nrows("SELECT song.id, song.title as song, artist.name as artist FROM song, artist where song.artist_id = artist.id")
