### What changes were proposed in this pull request?
When EXECUTE IMMEDIATE 'load data inpath ''/tmp/test.txt'' OVERWRITE INTO
table test_table' query is executed then the load data into table query will
directly send to HS2 and its get executed. After the query is executed by HS2
the control will be back to HPLSQL code in which it is trying to check the
resultset metadata but in this case there is no resultset as its a load data
query so it throws NPE which resulting HPLSQL error on the console even though
data is successfully loaded into the table. So here we need to check whether
the query result has resultset then only access its metadata.
