[jinyistudio]

Hi

when i run thd1.Start, B4j always give me a error from Thd1_Ended. the error is Exception:null.

I cann't run ExecSql, Why ????

Private thd1 As Thread
thd1.Initialise("thd1")

thd1.Start(Me,"ExecSql",Array As String("Record",s1))

Sub ExecSql(flow As String,sqls As String)
    If (sqls="") Then Return
    Dim sq As SQL' = DB.pool.GetConnection 'get a DB connection (change DB to Main)
    sq.InitializeSQLite(File.DirApp, "gsmgateway.db3", False)
    'sq.Initialize2("com.mysql.jdbc.Driver", "jdbc:mysql://" & db_host & "/data1?characterEncoding=utf8",db_account,db_passwd) 
    sq.BeginTransaction
    Try
        sq.ExecNonQuery(sqls)
        sq.TransactionSuccessful
        Log(flow) 
    Catch
     
        If LastException.IsInitialized Then
            Log(flow & " Exp:"&LastException.Message)
        Else
            Log(flow & " Exp:Error")
        End If
    End Try
End Sub

Sub Thd1_Ended(endedOK As Boolean, error As String) 'The thread has terminated. If endedOK is False error holds the reason for failure
   If endedOK Then
     Log("thd1 OK")
   Else
     Log("thd1 NG:"&error)
   End If
End Sub
