How much sql java junior should know?

Question

Career in IT

Hello!
At this time, I am at the stage of studying java core and then I wondered whether it is worth learning sql at this stage or should I not bother for now?

Answer 1

It is desirable to know at least basic queries, such as creating-deleting tables, inserting-modifying-deleting rows and selects with joins:
SELECT
JOIN
CREATE
DROP
DELETE
UPDATE
INSERT
This is something without which it is unlikely to work with databases.
