Does that mean that you allow reading the resultset AFTER the transaction completes? I was assuming the transaction
Of course. Under most conditions (ie. with setAutoCommit==true), the transaction is complete and closed before the
ResultSet is even returned to the client.
This is how JDBC works on most databases.
So most people tend to call getBlob() and expect it to work, even though they
are now fetching data outside a transaction.
And they expect it to work even if something else deletes the LOB while they
are reading it - outside the transaction :-(
So fixing this requires some work, and requires a fair amount of care on the part of people writing code to read LOBs
from H2.
