Multiple inserts
Hi
I am noticing that if I do this
insert into table values(1,a)
insert into table values(2,b)
insert into table values(3,c)
....
commit after 500 rows
it is lot slower (almost 10x) than
insert into table values((1,a),(2,b),(3,c)) .. upto 500
It is obvious that the gain is due to network trip avoided after every insert.
My question is: Are they any known side-effects or drawbacks of using multiple inserts. I am aware the error checking is much more difficult in the second approach. Any other drawbacks?
thanks
If the connection is in autocommit, then each statement will also incur a
commit (write to the commit log on disk).
