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

If table is without partition then code will be,

Insert into table table_name select col_a,col_b,col_c from another_table(source table)

--here any condition can be applied such as limit, group by, order by etc...

If table is with partitions then code will be,

set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;

insert into table table_name partition(partition_col1, paritition_col2) select col_a,col_b,col_c,partition_col1,partition_col2 from another_table(source table)

--here any condition can be applied such as limit, group by, order by etc...
