我回答如下问题:
a. select * from TABLE_TEMP
The query is executed successfully but, no rows are returned. the returned dataset is empty and contains 0 rows. The execution plan of this query can be downloaded from : Execution Plan Query a
b. select count(*) from TABLE_TEMP
This query is also executed successfully but, it returns some finite value The execution plan of this query can be downloaded from : Execution Plan Query b
你们能够向我提供解决这一问题的任何要点。
