Dear,

This is my code, but it don't work and i don't know how to fix it.

1.
I need to select the 'Gebruikersnaam' out of the table 'Gebruiker' Where 'Gebruikernaam' is the same as the edittext.

2.
If job1 is true so there is a match I would like to have an error message and say that that username already exists.

Can you help me with this pleas? Thanks

B4X: 
Sub CheckIfUsersExists
   
    job1.Initialize("Job1", Me)
    job1.PostString(ServerUrl,"SELECT Gebruikersnaam FROM Gebruiker WHERE Gebruikersnaam ='"&edtGebruikersnaam.Text&"'")
   
    Log(job1.ErrorMessage)
    Log("HttpUtils.GetString(SELECT Gebruikersnaam FROM Gebruiker) --> CheckIfUserExists")
    Log("Gebruikersnaam ="& edtGebruikersnaam.Text)

End Sub
