There's an issue with your query:
CREATE TABLE IF NOT EXISTS Account ( Name TEXT, Password TEXT, IP NUMERIC, Level NUMERIC, Cash NUMERIC, Bank NUMERIC, )Can you see it?
Bank NUMERIC, )
There's a comma "," symbol that isn't supposed to be there at the end:
CREATE TABLE IF NOT EXISTS Account ( Name TEXT, Password TEXT, IP NUMERIC, Level NUMERIC, Cash NUMERIC, Bank NUMERIC )
EDIT:
But that whole query is wrong and my recommendation is to get rid or it. Try the following example and see if it works:
// General global constants
const MAX_NAME_LENGTH = 128;
const MAX_PASSWORD_LENGTH = 128;
const MAX_ADDRESS_LENGTH = 16;
// Global variable holding the database handle
local g_DB = null;
function checkDb(name)
{
	// If the database file doesn't exist then try to create one
	local fp = file(name, "a");
	// Check if the previous action succeeded
	if (fp == null)
	{
		print("Unable to open or create the file: " + name);
		// No point in going forward
		return false;
	}
	// Now we know the database file exists and can be opened.
	else fp.close();
	// Try to open the file as an SQLite database
	g_DB = ConnectSQL(name);
	// Check if the previous action succeeded
	if (g_DB == null)
	{
		print("Unable to open the SQLite database: " + name);
		// No point in going forward
		return false;
	}
	else return true;
}
function onServerStart()
{
	if (!checkDb("mydb.db")) return 0;
	// Try to create the table
	QuerySQL(g_DB, format(@"CREATE TABLE IF NOT EXISTS [Account] (
		[Name] VARCHAR(%u)  NOT NULL,
		[Password] VARCHAR(%u)  NOT NULL,
		[IP] VARCHAR(%u)  NULL,
		[Level] NUMERIC DEFAULT '0' NULL,
		[Cash] NUMERIC DEFAULT '0' NULL,
		[Bank] NUMERIC DEFAULT '0' NULL
	);", MAX_NAME_LENGTH, MAX_PASSWORD_LENGTH, MAX_ADDRESS_LENGTH));
}
