[jira] [Created] (TRAFODION-2714) odb does not load data correctly
Rohit Jain created TRAFODION-2714:
-------------------------------------
Summary: odb does not load data correctly
Key: TRAFODION-2714
URL: https://issues.apache.org/jira/browse/TRAFODION-2714
Project: Apache Trafodion
Issue Type: Bug
Components: db-utility-odb
Affects Versions: 2.3-incubating
Environment: Internal Esgyn system nap043 and Windows laptop
Reporter: Rohit Jain
I was trying to load a trafodion table via odb but I had rearranged the sequence of the columns to be loaded. I used a map file to load the data. I tried to load just 10 rows and verified that the source and target data were in fact the same, before loading the entire table. To my surprise odb had loaded all columns correctly but two. It had set the values of one of those two columns to zero and had set the value of the first column to what should have been the value in the other column.
When I have the columns in the table arranged in the same sequence as those in the csv file, and don't have a mapping table, since it is not needed in that case, everything loads correctly.
On nap043 in /disk1/rohit you will find movie_metadata.csv.
The table I loaded the data into is:
invoke movies_denorm;

I used the latest version of odb from my Windows laptop using the latest version of the JDBC driver. Here is the load command:
odb -u trafodion -p traf123 -d esgyndb -l src=movie_metadata.csv:tgt=TRAFODION.MOVIES.MOVIES_ORIG:skip=1:loadcmd=UL:truncate:map=movies_odb_column_map.txt
mapping:

In the csv file you can see that the 3rd column in the first two rows is num_critic_for_reviews and has the values 723 and 302. odb uses a column offset starting from zero, which for most folks like me is very confusing. This column after the load has zeros in all the 10 sample rows I loaded.
Also, the last entry in the map list is movie_facebook_likes. This column has the values 33,000 and 0 in the csv column. In the table this column has the values 723 and 302.
So, the values that should have been in the column num_critics_for_review are in movie_facebook_likes, and the num_critics_for_review has the value zero in all rows. All other columns have the correct values in them.
