I am trying to find the minimum priced holiday for each month from each departure airport to a target destination airport from a table with over 1 million records. I have successfully created the required MySQL query :-
SELECT * FROM results r INNER JOIN (SELECT id,MIN(price) FROM results GROUP BY BulkLoaderRef) r2 ON r.id=r2.id ORDER BY r.departureDate, r.depAirportCode, r.resortID LIMIT 10
But I cannot find a valid JPQL syntax for this query?
Help please?
My table format is as follows :-
CREATE TABLE `results` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,

JPQL doesn't support sub-queries for JOIN statements. With that said, I would suggest that you move the subquery of your JOIN into a view. Then it becomes a simple JPQL statement.
Move subquery into a view:
CREATE VIEW min_price_view AS
SELECT id,MIN(price) FROM results GROUP BY BulkLoaderRef;
Then replace in query:
SELECT
*
FROM
results r
INNER JOIN
min_price_view r2 ON r.id=r2.id
ORDER BY
r.departureDate, r.depAirportCode, r.resortID
LIMIT 10
At this point, it becomes very simple to convert it to JPQL.

Why is this statement failing despite the "IF NOT EXISTS" clause?

The error only happens when concurrent connections are established.
If I set the pool size to 1 it does not occur.
If I set the pool size to 2 I see it logged once.
If I set the pool size to 3 I see it logged twice.
The error seems to be gone when the connection pool retries.
It all looks like a concurrency bug in H2
IF NOT EXISTS checks only presence of constraint with exactly the same name. This exception indicates that your table already has a primary key constraint with the same or other set of columns, but with different name.
If you're sure that this table either has a primary key constraint on these two columns with unknown name or doesn't have a primary key constraint at all, you can replace your command with the following one:
EXECUTE IMMEDIATE
CASE WHEN NOT EXISTS (
SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE TABLE_NAME = 'QRTZ_CALENDARS' AND CONSTRAINT_TYPE = 'PRIMARY KEY')
THEN 'ALTER TABLE QRTZ_CALENDARS ADD CONSTRAINT PK_QRTZ_CALENDARS PRIMARY KEY (SCHED_NAME, CALENDAR_NAME)'
ELSE ''
END;
I Have a file with below data, in which I want to replace everything in line after a Default nextval with AUTO_INCREMENT
I tries sed command but it didn't help
Data:

`id` bigint(20) NOT NULL DEFAULT nextval(`xchange_finance`.`seq_invoice`),
`id` bigint(20) NOT NULL DEFAULT nextval(`xchange_finance`.`seq_invoice_attachment`),
`id` bigint(20) NOT NULL DEFAULT nextval(`xchange_finance`.`seq_invoice_line_item`),
expected:

`id` bigint(20) NOT NULL AUTO_INCREMENT ,
`id` bigint(20) NOT NULL AUTO_INCREMENT ,
`id` bigint(20) NOT NULL AUTO_INCREMENT
tried something like below but it didn't work
sed -e 's/^DEFAULT nextval.*$/AUTO_INCREMENT ,/g' test

Problem
Query with order by is too slow. Is there a way to speed up query with some index or server settings? I need order by for pagination.
The goal is to select all images for project and send them through the api to another server.
I'm using mariadb 10.8.2
Server is on SSD with 8GB RAM
My error:
ORA 00907: Missing Right Parenthesis
My code:

There's no variable type named CHARACTER in oracle, as an alternative, you to use VARCHAR2 with length value in parenthesis.
You can use INTEGER type without length.
