Vineet Garg updated HIVE-23950:
-------------------------------
Description:
PREPARE and EXECUTE statements provide an ability to create a parameterized
query and re-use it to execute with different parameters.
e.g.
{code:sql}
PREPARE pcount from
select count(*) from src where key > ?;
EXECUTE pcount using 200;
-- execute with different value
EXECUTE pcount using 101;
PREPARE pquery2 from
select count(*) from daysales where dt=? and customer=?;
EXECUTE pquery2 using '2001-01-01',1;
{code}
