我们在MariaDB中有一个存储过程，在服务器上运行良好，但是当我们使用JDBC从客户端运行时，我们可以获取到前几行，但是后面总是出现以下错误：

unexpected end of stream, read 0 bytes from 4 (socket was closed by server)

表loan_balances2不是太大，大约有600K行。这是存储过程，你看到有什么问题吗？谢谢！

CREATE PROCEDURE `get_loan_balances_sample`()

BEGIN

drop table if exists all_loan_ids;
drop table if exists random_loan_ids;

create table all_loan_ids as select distinct loan_id from loan_balances2;
create table random_loan_ids as select * from all_loan_ids order by RAND() limit 50;

SELECT * FROM loan_balances2
where loan_id in (select Loan_ID from random_loan_ids)
order by Loan_ID, balance_date;

END
