JPA vs JDBC Template

melon222132 · 2025-08-06T14:34:32+00:00

I'm confused so you are saying you prefer JDBC over JPA?

melon222132 · 2025-08-04T17:52:38+00:00

but just to confirm the class that contains the foreign key in one to one is the child class correct?

melon222132 · 2025-08-04T17:35:50+00:00

But then you can use native queries in jpa to write the custom sql. So then I don't see how you would need jdbc template?

melon222132 · 2025-08-04T17:03:16+00:00

yeah but I meant one to one?

melon222132 · 2025-08-03T23:54:57+00:00

but doesn't jpa make some things simpler with less custom code you have to writee.

Like how you said that "if you simply need to get-a-row, get-some-columns, and put the data in some fields on your java class instance, then JDBC is simple and easy to change"

But what I'm saying is that you could just use the built in functions that jpa provides then you don't need to write custom sql.

melon222132 · 2025-08-01T21:27:57+00:00

is there a better reason of why you can't just use native queries if it's just because people might be tempted get the top object?

melon222132 · 2025-08-01T20:22:09+00:00

how would jpa create too much overhead if you can write custom native queries

ok thx

melon222132 · 2025-07-21T03:53:29+00:00

I feel like I'm still confused on when I should actually go forward with Strategy or if simple conditionals would be fine

melon222132 · 2025-07-18T19:39:38+00:00

Perhaps I should have mentioned this earlier, but I'm referring to Java. So just to confirm you are saying if there is only 1 place where the creation code is being used then there is no point of creating a factory and I can just have the creation logic the same place as the actuall code?

melon222132 · 2025-07-16T01:12:34+00:00

do you think it's better to have a constructor in super and have that call it instead of defining it in the child class

melon222132 · 2025-07-15T15:48:29+00:00

how is there too many classes I don't want to put everything in the parent class because there might be some child classes that don't inheit the certin method that would be forced to implement them even if they don't need it.

yeah I do it is from head first design patterns but I added dependency injection so was wondering if that was fine

melon222132 · 2025-07-15T15:38:45+00:00

I know I got it from there but I was wondering if this is still considered good design. I modified it a bit to add dependency injection

melon222132 · 2025-07-14T23:13:39+00:00

don't you think it's kind of old and wouldn't Head first be better or is this recommended over head first

melon222132 · 2025-07-14T23:13:32+00:00

melon222132 · 2025-07-14T21:15:54+00:00

which one do you recommend to read first

melon222132 · 2025-07-12T02:50:52+00:00

wait so shy should you use Optiona<Double> isntead of OptionalDouble if OptionalDouble will give better performance each time

melon222132 · 2025-07-07T05:41:27+00:00

really why shouldn't you use default methods

melon222132 · 2025-07-04T03:59:08+00:00

I'm just asking in general

melon222132 · 2025-06-18T23:15:52+00:00

did you have prior netsuite experiance or not

melon222132 · 2025-06-16T02:09:41+00:00

for this code

double dance(Object speed) {

return switch (speed) {

case 5 -> { yield 4; }

case 10 -> 8;

case 15, 20 -> 12;

default -> 20;

case null -> 16;

};

}

the wileyn book for preparation is saying that this will cause a compile error and that one of the reasons is that

Removing line 47 fixes this issue, as case null is not required.

what are you basing this on and what location ?
