Trouble inserting data into an sqlite3 database

[DrMasik]

Any questions?

The problem I have now is using a SELECT query: if the result contains data from the database it runs fine, if not, it errors out instead.
Like I said, it breaks on stmt:get_values().

Replace

Code:

stmt:get_values()

to

Code:

local dataCol1;
local dataCol2;

for col1, col2 in stmt:urows() do
  dataCol1 = col1;
  dataCol2 = col2;
end

-- If no cycle dataCol2 == nil and dataCol2 == nil

Sorry for the really, really late response. I just gave up on it basically.

Current code:

function ExecuteStatement(sql, parameters)
	local db = sqlite3.open(PLUGIN:GetLocalFolder() .. "/database.sqlite3");
	local stmt = db:prepare(sql);

	if not (parameters == nil) then
		for key, value in pairs(parameters) do
			stmt:bind(key, value)
			stmt:step();
		end
		--stmt:bind_names(parameters);
		--stmt:step();
	end

	local result;
	if (sql:match("SELECT")) then
		local x = 1;
		for row in stmt:urows() do
			result = row;
			x = x + 1;
			LOG("TEST");
		end
		--LOG(stmt);
	elseif (sql:match("INSERT")) then
		--result = stmt:last_insert_rowid();
		LOG("INSERT");
	else
		LOG("NOTHING");
	end

	stmt:finalize();

	db:close();

	if not (result == nil) then
		return result;
	else
		return 0;
	end
end

I'm 100% sure that the SELECT query I'm running should return at least 1 row. However, it doesn't go into the loop even once. It doesn't break, it just doesn't run properly.

I've tried urows, nrows and rows, but none of them seem to do anything.

I think the problem may be with stepping the statement while binding values. You should first bind all values and then do a single step - move line 8 to line 10.
Here's an "ExecuteStatement()" function that has been tested to work on Windows x64, Linux x86 and RasPi (and is likely to work anywhere):

Actually I finally fixed the problem using the guide here.
I had to use stmt:step() in the loop instead of stmt:rows. It now worsk perfectly!
