Hallo All, I am working with Sqoop for writing data back to Database from HDFS, I am currently stuck in an issue, the scenerio is like,
I have a Postgres database with a table TestSqoop consisting of three fields, *id integer SERIAL, volume numeric(8,2), zip integer* where id is the autoincrement field, I am having a data file in HDFS where I want to insert only last two rows(except id which is already auto incremented) so if my data file contains the data in this format 1,28.00,10005 2,403.71,90210 3,20.02,95014 where I am specifying the value even for the id which I don't want as it should be auto incremented. Kindly let me know if there is a way round so that I can neglect the id attribute value in my data file so that it should auto increment in Database. Urgent!!!
