<div>All,</div>
<div> </div>
<div>I am trying to use ogr2ogr as a scheduled command line task to run weekly to convert a .SHP file to a .TAB file whilst filtering the data based on a date field. I would like to only convert records that have a date from the last 30 days.</div>
<div> </div>
<div>Therefore If the task ran today (11/07/2011) the below line would return the required data:</div>
<div> </div>
<div>ogr2ogr -f "MapInfo File" -sql "select * from DCPOLY where DATE_CREA1>'2011/06/11'" D:\Data\Plan_Apps.tab D:\Data\DCPOLY.shp</div>
<div> </div>
<div>Obviously if the task ran tomorrow the date would have to be changed to '2011/06/12'. So I need the field SQL to be something like:</div>
<div> </div>
<div>DATE_CREA1> Todays_Date - 30</div>
<div> </div>
<div>Does anyone know of a way to automate this using something like; GetDate(), Now(), sysdate, Date /t, etc? Any help would be greatly appreciated.</div>
<div> </div>
<div>Many thanks,</div>
<div> </div>
