Reliablility of Statement.getGeneratedKeys()

Question

I found that Statement.getGeneratedKeys() can be used for retrieving the ids of the inserted rows. But I wanted to know is it reliable, if we have multiple JDBC connections performing insert operation simultaneously.

Answer 1

From Docs of getGeneratedKeys()

Retrieves any auto-generated keys created as a result of executing this Statement object.

When you create a Statement from a Connection Object, the generated keys are belongs to that particular statement. And they return the specific id's inserted. So you'll safely get those.

Answer 2

除非您正确使用JDBC，否则工作正常，直到很长时间为止。我使用getGeneratedKeys（）已有很长时间，并且直到现在都没有遇到任何问题。
