Double arrays in a table

[Seif]

Since setElementData seems to be slow, I said I'd use tables instead. However I don't know how I would make a multi-dimensional table. If I do:

sourceTable = {}{}

it will give me an error, saying I must only have 1 {}. This is made serverside so I want to have a slot for the source and one for the variables I want to store in. Any possibility?

ever though about sql?

What does SQL have to do with this?

It must be sourceTable = {{}} instead of sourceTable = {}{}. However, only sourceTable[1] will be the table, other values will be nil as they aren't set to any value. So you need to set them yourself when the source is created. If the source is player, it can be like this:

sourceTable = {}
 
function playerJoined()
   sourceTable[source] = {}
end
addEventHandler("onPlayerJoin",getRootElement(),playerJoined)
 
function playerLeft()
   sourceTable[source] = nil
end
addEventHandler("onPlayerQuit",getRootElement(),playerLeft)

I tried that but it gives me this error:

"attempt to index field "?" (a nil value)"

when I try this:

sourceTable[source][sqlid] = row[1]

[DiSaMe]

It means that source or SQLid has no value.

[Seif]

Then how am I suppose to set it a value if it keeps giving me that error?

You have to do this first:

sourceTable[source] = {}

With this you create a new sub-table at index location [source].

I did do it when the player connects.

Then show us your function...
