Gavin 2e502215d5 update the docs with new @FetchProfileOverride 
and the "default" profile
 2023-05-23 16:50:25 +02:00
Gavin 66d67795a3 HHH-16666 fix test 2023-05-23 16:50:25 +02:00
Gavin 176abffdd5 HHH-16654 introduce a "default" fetch profile with eager to-ones in it 
also, make the query translator always respect the fetch type specified
in the fetch profile (previously it would ignore it for statically-EAGER
many-to-ones, which was inconsistent and made little sense)

Gavin b3e27788fa fix bug in query plan cache where fetch profiles were not considered 2023-05-23 16:50:25 +02:00
Gavin ba0221da36 HHH-16666 introduce @FetchProfileOverride instead of reusing @Fetch 
There are differences in the implied timing, so this is more consistent

Gavin 9c90bd505d HHH-16651 clean up API of the engine.profile package

Gavin 36a77785e8 HHH-16666 give @FetchOverride.mode a default (the only supported value!) 
Talk about low-hanging fruit!
 2023-05-22 18:45:41 +02:00
Gavin f2dbe7a9cb HHH-16666 allow fetch profiles to be defined using the @Fetch annotation 
1. You may now declare an empty named @FetchProfile, and
2. add associations to it using @Fetch.

Note that @Fetch becomes a repeatable annotation.

Gavin 2daeadd449 share more code between the batch loaders 2023-05-22 18:45:28 +02:00
Gavin 2926d1781d trim array holding batch of ids before passing to JDBC 
before this, the array length was the batch size, and
was padded with nulls, which isn't great if you have
a large batch size, I suppose

Gavin 4ebc24daa0 HHH-16650 add test 2023-05-22 10:07:27 +02:00
Gavin eded6e8ff9 HHH-16650 fix for native queries with "unknown" numeric types on Oracle 
Oracle reports FLOAT/DOUBLE PRECISION as NUMBER, which is wrong. The
workaround was to look at the scale, which it reports as -127 for
FLOAT. But certain other expression also get scale -127, and this
could cause truncation of least-significant digits when we read them
into a Java Double.
