My query is select count(1) from db.table;
. How can I execute this query and set it to hivevar:hive_count
within a hiveql script?
Something along the lines of ...
> set hivevar:hive_count=(select count(1) from db.table);
> ! echo ${hivevar:hive_count}
43
Right now this is what happens...
> set hivevar:hive_count=(select count(1) from db.table);
> ! echo ${hivevar:hive_count}
(select count(1) from db.table)
The query is NOT executed. I want to be able to save the query result to a hivevar
in which I can echo later
