I have a small problem ! only 1 marker displayed on maps ! You know the way


B4X:
dbsql.Initialize(File.DirRootExternal,"Mybase.db",True)
dbcursor = dbsql.ExecQuery("SELECT * FROM Field")
'dbcursor = dbsql.ExecQuery("SELECT Field1, Field2, Field3, field4 FROM Field")
For i = 0 To dbcursor.RowCount -1
DoEvents
dbcursor.Position = i

Dim lat, lng As Double
Dim nms As String
Dim colr As Int

lat = dbcursor.GetDouble("Field1") ' Lat
lng = dbcursor.GetDouble("Field2")  'Lng
nms = dbcursor.GetString("Field3") ' Name
colr = dbcursor.GetInt("Field4")    'Color

Next
dbcursor.Close

'gmap.AddMarker2(dbsql.ExecQuerySingleResult("SELECT Field1 FROM Field"),dbsql.ExecQuerySingleResult("SELECT Field2 FROM Field"),dbsql.ExecQuerySingleResult("SELECT Field3 FROM Field"), dbsql.ExecQuerySingleResult("SELECT Field4 FROM Field"))
