Insert data into hive table

Question

Using a Cygwin distribution, I\'ve installed Hadoop 0.20.3 and Hive 0.11.0.

First of all, I don\'t understand how to use the Hive CLI:

hive> show tabl         


        

Answer 1

You can insert new data into table by two ways.

1. Load the data of a file into table using load command.

   LOAD DATA [LOCAL] INPATH 'filepath' [OVERWRITE] INTO TABLE tablename.
   

2. You can insert new data into table by using select query.

   INSERT INTO table tablename1 select columnlist FROM secondtable;
