2 Data stores in one game

Help and Feedback Scripting Support
#1

Is it possible to have 2 data stores in one game? For example these are 2 server scripts and first one has this code:

local DSS = game:GetService("DataStoreService")
local DataA = DSS:GetDataStore("DataStoreA")

local function do_Stuff_with_datastoreA
    DataA:SetAsync(blah blah, false)
end

The second one has this code:

local DSS = game:GetService("DataStoreService")
local DataB = DSS:GetDataStore("DataStoreB")

local function do_Stuff_with_datastoreB
    DataB:SetAsync(blah blah, true)
end

If I insert this code somewhere in the second script, will it work or not:

game.Players.PlayerAdded:Connect(function(plr)
   if DataB:GetAsync(player.UserId) == true then
     print("do some stuff")
  end
end)

Will it print out “do some stuff” or can you not have 2 data stores i.e. DataStoreA & DataStoreB?

#2

Have you tried doing this before?

#3

No, because I am afraid it will mess up my data stores.

#4

This should work perfectly fine I’m pretty sure.

#5

Haven’t tried this myself before, but I can see it working perfectly fine. I usually just use a single DataStore, and save tables of information.

#6

How can I use the single datastore/tables method?

#7 
local DSS = game:GetService("DataStoreService")
local DataA = DSS:GetDataStore("DataStoreA")

local Data = {Data1 = blah, blah, false;
Data2 = blah2, blah2, true;}
local function do_Stuff_with_datastoreA
    DataA:SetAsync(Data)
end

I think that’s how its done.

This is how its done in a normal data store script:

local DataStoreService = game:GetService("DataStoreService")
local DataStore1 = DataStoreService:GetDataStore("DataStore1") 

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local Points = Instance.new("IntValue")
	Points.Name = "Points"
	Points.Parent = leaderstats
	
	local Cash = Instance.new("IntValue")
	Cash.Name = "Cash"
	Cash.Parent = leaderstats
	
	
	local playerUserId = "Player_"..player.UserId
	
	-- Load Data
	
	local success, errormessage = pcall(function()
		data = DataStore1:GetAsync(playerUserId)
	end)
	
	if success then
		Points.Value = data.Points
		Cash.Value = data.Cash
	end
	
end)

game.Players.PlayerRemoving:Connect(function(player)
	local playerUserId = "Player_"..player.UserId
	
	local data = {Points = player.leaderstats.Points.Value;
		Cash = player.leaderstats.Cash.Value
	}
	
	
	local success, errormessage = pcall(function()
		DataStore1:SetAsync(playerUserId, data)
	end)
	
	
	if success then
		print("Data successfully saved")
	else
		print("There was a error when saving data")
		warn(errormessage)
	end

end)

Yes.

And, wrap your calls in a pcall.

Yes, you can use 2 data stores. BUT, I recommend using one with a different “key”, here’s an example:
local datastore = game:GetService("DataStoreService"):GetDataStore("NameOfTheDatastore")
game.Players.PlayerAdded:Connect(function(plr)
datastore:SetAsync(plr.UserId .. "weapon", "someweaponname")
datastore:SetAsync(plr.UserId .. "name", plr.Name)
end
Hopefully that makes it less confusing for you :slight_smile:
Sorry for the lack of indents, I am new to devforum.

There are two way of doing it, one of them is already mentioned by others in here, Just combine both in a table and store.

You can also access two data stores in one script.

local DSS = game:GetService("DataStoreService")
local DataA = DSS:GetDataStore("DataStoreA")
local DataB = DSS:GetDataStore("DataStoreB")

local function do_Stuff_with_datastoreA
    DataA:SetAsync(blah blah, false)
end

local function do_Stuff_with_datastoreB
    DataB:SetAsync(blah blah, true)
end

And yes, it will print.

data can be nil if there is nothing saved, this will result in a error when setting the value, you can fix it by doing

if success and data then
end

or

Value = data.Points or 0 -- it will be 0 if the data is nil.
#13

Not, really, if there is no data it will just be zero, not nil

#14

No, the data WILL be nil if nothing is saved, think of it like doing

local Test
print(Test) -- nil
#15

In regular data stores we use intvalues, which default value is 0:

Are you sure about that.

Yes, the number is converted to 0 if the returned data is nil, a string or any bool-values.

However, the actual returned data is nil, when setting its value, it will automatically be set to 0 as explained above, as the returned data is not a valid number.

In cases where we are using StringValues or similar things, this method is highly recommended.
