Hi all,</div><div> </div><div>I am quite new to pl/pgsql and completely confused. </div><div>I have two tables. One storing height category including hk_id(height category id), h_min and h_max. and a table including several plygons having y_max and height. My aim is to know on which height category the plygon locates based on its y_max.</div>
<div>My piece of code is like:</div><div> </div><div>i=1; a=0;</div><div>while (i=<4 , a=0){</div><div> if h(i)_min < y_max < h(i)_max</div><div> {height = i</div><div> a = 1;}</div>
<div> i = i + 1</div><div> }</div><div> </div><div>Is there any body who can help me to convert this piece of code to excutable format in pl/pgsql?</div><div> </div><div>Thank you in
advance</div><div>Many</div><div> </div><div><br clear="all"></div></div></div><br>_______________________________________________<br>
