Question

ich die folgenden Beispieldaten haben und ich versuche, es in Bienenstock zu explodieren .. Ich Split verwendet, aber ich weiß, ich bin etwas fehlt ..

["[[-80.742426,35.23248],[-80.740424,35.23184],[-80.739583,35.231562],[-80.735935,35.23041],[-80.728624,35.228069],[-80.727753,35.227836],[-80.727294,35.227741],[-80.726762,35.227647],[-80.726321,35.227594],[-80.725687,35.227544],[-80.725134,35.227535],[-80.721502,35.227615],[-80.691298,35.216202],[-80.688009,35.215396],[-80.686516,35.215016],[-80.598433,35.234307]]"] 

benutzte ich die folgenden Abfrage

Wählen Sie explode (split (col, ',')) von sample2;
und das Ergebnis ist die

 ["[[-80.742426 
     35.23248] 
     [-80.740424 
     35.23184]

     35.208806] 
     [-80.598433

Ich brauche es in folgendem Format

[-80.742426,35.23248]

    [-80.739583,35.231562]

Jede Hilfe hier über ..?

Answer 1

Sie haben Ihre Daten als Arrays von Array und Sie möchten Ihre Daten nur auf der ersten Ebene explodieren, also verwenden Sie LATERAL VIEW explode(colname), um auf der ersten Ebene zu explodieren.

Unten ist die SELECT Abfrage mit explode():

select col1 from sample2 LATERAL VIEW explode(col) explodeVal AS col1; 

Ausgang erzeugt aus dem Eingangsdaten wie unten beschrieben:
