	umsg.End()
end

sql.lua

local ply = FindMetaTable("Player")
function CreateTable()
	sql.Query("CREATE TABLE player_data ( UniqueID string, prime string , sec string ,  melee string , grenades string)")
end
function ply:createSQL()
	if !sql.TableExists("player_data") then CreateTable() end
	t = sql.Query("SELECT UniqueID FROM player_data")
	if t != nil or t != false then 
		for i,k in pairs(t) do
			if k.UniqueID == self:UniqueID() then print("nope") return false end
		end
	end
	sql.Query("INSERT INTO player_data ( UniqueID ,prime ,sec ,melee ,grenades) VALUES ('" .. self:UniqueID() .. "','ak47','deagle','knife','smoke_grenade')" )
end
function ply:GetLoadout(key)
	if !sql.TableExists("player_data") then CreateTable() end
	if key == "prime" then
	        Table = sql.Query("SELECT prime FROM player_data WHERE UniqueID = "..self:UniqueID())
		print(sql.LastError())
		print(Table)
		return Table
	elseif key == "sec" then

First off, stop using umsg, use the [URL="https://wiki.garrysmod.com/page/Net_Library_Usage"]Net Library[/URL] instead.

And why are you running createSQL() on the player? Hope you know this means you're attempting to create player_data every time you call it on a player. You should use the Initialize hook instead.
