mandra · August 25, 2017, 7:55pm

I have this error someone have the solution ?

TheRealSinTV · August 27, 2017, 9:16pm

Anyone answer you or did you figure it out? I’m in the same boat here

Brouznouf · August 28, 2017, 11:32pm

@xander1998 There was a bug in old versions of mysql async it should be resolved on master will do a version in some hours / minutes

@Quentins The error tell it all, connection is impossible : check the host / username / password that you entered in the mysql_connect_string setting

@mandra Not related to mysql, it just say that a Native don’t work

Brouznouf · August 28, 2017, 11:41pm

Hi since we need to use “MySQL.ready”, scripts in this function doesn’t execute anymore
EDIT : I have found the problem: Citizen.CreateThread Doesn't work serverside

Titch2000 · September 1, 2017, 4:41pm

Hi, i am getting an issue with :

I have got MySQL working with other scripts using all the same ways just different databases and things like that i have also done the following in my __resource file:

But i still continue to get the error here is the cause at line 42 but i cannot see the issue:

Thanks for any help you can give.

Brouznouf · September 2, 2017, 3:02pm

you put a function in your parameters

Deveraux · September 2, 2017, 3:42pm

Sorry what do you mean? I’m still relatively new at this. Cheers for the reply though!

Brouznouf · September 2, 2017, 4:19pm

Show the code that give this error, will tell you why then

Deveraux · September 2, 2017, 4:26pm

I wish I knew, I’ve just setup mysql async and as soon as I log into the Server this pops up.

Deveraux · September 2, 2017, 4:34pm

I’m off to bed, literally been at this for 11 hours - If you have any suggestions how to fix them please post and ill try in the morning. Thanks for replying already anyway! Your a champion.

Brouznouf · September 3, 2017, 12:18pm

New Expiremental API for mysql-async only available since build 363 of fivem, this API, will be the official and recommended way in future

https://github.com/brouznouf/fivem-mysql-async/tree/feature/promise-await

New api using coroutine to have a sync feeling while still being async : local result = MySQL.[execute|fetchScalar|fetchAll|insert](query, params) which is possible due to the Citizen.Await function which allow to wait in an asynchronous way promises.

    -- Not blocking the main thread, but block current execution context
    print(MySQL.fetchScalar('SELECT NOW() as world'))

All async functions now returns a promise which can be chained by using the next method

-- Promise api
local p = MySQL.Async.fetchScalar("SELECT 1")
p:next(function (result)
    print(result)

    return "test"
end):next(function (result)
    print(result)

    error 'An error'
end):next(nil, function(err)
    print(err)

    return ""
end)

-- Synchronisation
promise.all({
    MySQL.Async.execute('SELECT SLEEP(1)'),
    MySQL.Async.fetchScalar('SELECT "test"'),
}):next(function (results)
    print(json.encode(results))
end)

ferrum · September 3, 2017, 12:27pm

did you forget to call Await in the first sample or do you provide it in your wrapper?

Brouznouf · September 3, 2017, 12:32pm

It’s provide in the wrapper :

MySQL.x : Async + Await (non blocking io)
MySQL.Async.x : Async (return promise)
MySQL.Sync.x : blocking api (faster in many cases as there is no async / thread overhead, but blocking)

im have one error fetchScalar with last build mysql-async

https://gyazo.com/8fa9ee7bf3fa159f209b6d5ad1be645c

cause this error is no result with request not return nil

Brouznouf · September 8, 2017, 8:53am

Look at the changelog it was fixed in the last version, simply update your mod

steven_dev · September 8, 2017, 4:41pm
