[chargeable] MSMySQL - Yet another MySQL-Library (but a FAST one :-))

[benji]

if i have more than one queryasync in the same activity, how can i differentiate each query_Result?
need three different connections?

 

[DonManfred]

QueryASync (query As String, Task As String)
You can set a different task. In the redulmeta this task will be part oft the content

 

[benji]

OK, i have this example(from here)...

Sub MySQL_QueryResult(data As List, meta As Map)
    ToastMessageShow(meta.Get("RecordCount") & " rows retrieved in " & meta.Get("ms") & " milliseconds", True)

    For i = 0 To data.Size - 1
        Log(data.Get(i))
    Next
    Log(data.Size) 
    Log(meta.Size) 
End Sub

in which part can i differentiate the task?

@benji here you go.

'First run your MySQL query using QueryASync and set your TaskID
     MySQLExe.QueryASync("SELECT * FROM ????", "Login") 'Set your TaskID. 'Login' = TaskID

'Second get your filtered TaskID results using the meta Map
Sub Query_QueryResult(data As List, meta As Map)
    Select meta.Get("TaskID") 'Get the TaskID
        Case "No"
            Log("No")
        Case "No Way"
            Log("No Way")
        Case "Login"     ''Login' is the TaskID
            Log("Login") ''Login' is now in the logs tab
        Case "Hell No"
            Log("Hell No")
    End Select
End Sub

Using Select means that you can filter multiple MySQL queries results with ease...

I'm coming back to this lib and i'm wondering how to do INSERT , UPDATE ,and DELETE ???

ExecuteASync ("DELETE FROM ....")
ExecuteASync ("UPDATE table SET ...")
ExecuteASync ("INSERT INTO table SET ...")

 

[jahswant]

This means they does n't have task identifiers like SELECTSs and what about feedbacks since they are nonqueries ???

 

[DonManfred]

You can use the batch. Here you get an result for each query you send
Actually it does not have a task. Maybe something for the next release

 

[jahswant]

Ok thanks but i'm awaiting task id's and nonqueries feedback ...

 

[DonManfred]

Ok thanks but i'm awaiting task id's and nonqueries feedback ...

i try to update my libraries this week to implement Tasks for each method

 

[swarupsengupto]

Just donated 5$. Will please send me the lib at [email protected]

 

[DonManfred]

Thank you.

Mail already send two minutes ago

 

[Peter Simpson]

Thank you for adding TaskId Manfred. Thanks for the great tech support

 

[jahswant]

@DonManfred is the dropbox automatically updated ???

 

[Peter Simpson]

@jahswani TaskId has been incorporated. Please look at DropBox, it should say that the file is only a few days old...

 

[DonManfred]

s the dropbox automatically updated ???

i DID upload the files to my dropbox. But it does not happen automatically.
I also posted a new post in the "Subscribe to Library-Updates thread" and updated the documentation in Post #1 of the lib with the new Version on wednesday.
When i do this post i already updated the files in my Dropbox.

unfortunately app has stopped.

You should post the error log while debugging.
Maybe the unfiltered

I am using basic4android 2.47

I´m not sure if the library and/or the native connector will work with this b4a-version.

I´m not sure at all if all the commands i used are compatible with this b4a-version. I dont have such an old b4a version.
I started developing with b4a 2 years ago. With version 2.78
I suggest considering updating your b4a version


Posting the error log will be the best to give us any hints on what´s going wrong.
