'ipairs' 的错误参数 #1(需要表，得到布尔值)

控制台错误；

117: call: failed to call 'mysql:select' [string "?"]
117: bad argument #1 to 'ipairs' <table expected, got boolean>

函数；

function openAdvertisements( player, command )
    local advertisements = { } --These will hold our advertisements to send to the client and populate our advertisement tables.

    if not player then player = source end

    --Fetch all of the advertisements from the database
    for _, ad in ipairs( exports.mysql:select('advertisements') ) do
        if tonumber( ad.expiry ) >= tonumber( getRealTime().timestamp ) then --Check if the advertisement has expired, delete it if so.
            ad.author = exports.mysql:select_one( "characters", { id = ad.created_by } ).charactername
            table.insert( advertisements, ad )
        else
            deleteAdvertisement( ad.id )
        end
    end

    triggerClientEvent( player, resourceName .. ":display_all", root, advertisements, exports.integration:isPlayerAdmin( player ) ) --Send the advertisements to the client to create the GUI.
end

第 117 行；对于 _, ipairs 中的广告(exports.mysql:select('advertisements')) 做离开Cs(cid)

exports.mysql:select("SELECT * FROM 'advertisements' WHERE <something>")
