I suspect this happened due to "database NULL" -> double conversion, but who knows...
What was the scale of your data (say, 1 GB)?
Yes, I used 1GB of data.
Can you tell me which version of VerdictDB you used?
I just ran the same query for TPCH 1GB, and it ran fine. FYI, I used pyverdict, which I installed by "pip install pyverdict --upgrade".
I'm using version 0.5.8 in Java. I did not want to do the queries in python. Now I got the result of the query, the error was when I was trying to print the resultset values (it returned string and I was trying to print double). Thanks
I'm using VerdictDB in Java, according to your tutorial. I saw in the paper that they used, for example, the query #tq-12 of TPC-H. If I use it in Java, I have this error:
Exception in thread "main" java.lang.NullPointerException at org.verdictdb.commons.AttributeValueRetrievalHelper.getDouble(AttributeValueRetrievalHelper.java:172) at org.verdictdb.jdbc41.VerdictResultSet.getDouble(VerdictResultSet.java:332) at Main.runQuery(Main.java:110) at Main.main(Main.java:61)
My code to run the query is:
