title: How do I get a list of columns from the Target Data Store in ODI 12 using groovy
body: <p>I'm looking through packages and classes (<a href="https://docs.oracle.com/middleware/1213/odi/reference-java-api/toc.html" rel="nofollow noreferrer">https://docs.oracle.com/middleware/1213/odi/reference-java-api/toc.html</a>) and I can't find anything to get a list of columns in my target data store.  Can you please show sample code or point me to a class I should look into?  I'm new to groovy and odi.  Any help would be great.  THANKS!</p>
