Android Question Types do not match

Hi Everyone,

I have some code below (2nd line) that seems to have an underline saying types do not match, I can't see why, and it does not seem to work... It just freezes the app and I can't see where it goes

B4X: 
Sub InsertLolerRequest
    
    Dim cmd As DBCommand = CreateCommand("insert_req_loler_31298", Array(1,0,1,Main.lngLolerKitID))
    Dim j As HttpJob = CreateRequest.Executebatch(cmd, Null)
    Wait For(j) JobDone(j As HttpJob)
    If j.Success Then
        Log("Inserted successfully!")
    End If
    j.Release
end sub

Any help would be appreciated, writing in b4a 10.0

Hi Erel,

That tutorial is where I got the code from, I just adapted the createcommand in line 3 to insert into my table on SQL Server.

The SQL side is as below

sql.insert_req_loler_31298=INSERT INTO tbl_system_requests(sys_type_ID,sys_status,sys_parm_1,sys_parm_2) VALUES (?,?,?,?);

It appears it is not waiting.... If I put in some code and add a break point in JobDone, it goes through and pauses there. Is there a reason why it would not wait and then execute the lines below? I checked the SQL table, and it is actually writing to the table ok.

I get this now on compile, perhaps there is an issue here...

1/ Click on ExecuteBatch in IDE, see what the hint help says it returns. Error indicates is returning String, which is usually the default if not otherwise specified. Should be As HttpJob.

2/ Make sure ExecuteBatch is defined in your project, probably in file DBRequestManager.bas from:

https://www.b4x.com/android/forum/t...ation-of-rdc-remote-database-connector.61801/

B4X: 
Public Sub ExecuteBatch(ListOfCommands As List, Tag As Object) As HttpJob
    Dim j As HttpJob = CreateJob
    ExecuteBatchImpl(j, ListOfCommands, Tag)
    Return j
End Sub

My public sub did not have the As HttpJob on the end, but I have not changed anything, do you think I am on an old version somehow? Mine is as below, looks nothing like yours

My Version of Execute batch: 
Public Sub ExecuteBatch(ListOfCommands As List, Tag As Object)
    Dim ser As B4XSerializator
    ser.Tag = Tag
    ser.ConvertObjectToBytesAsync(CreateMap("commands": ListOfCommands,  "version": VERSION), "ser")
End Sub
