My personal computer, the system is Windows 7 64 - bit, PL/SQL Developer installed version is 13.0.06.1911 64 - bit, and then, download the oracle instanceclient version is 19.3
64 - bit, ORALCE version is 12 c. 1. Using PL/SQL Developer can connect to the database, but execute the query, there is no output,

The same software, the company's computer system is Windows Server 2012, PL/SQL Developer queries can be normal output,

Does anyone encountered this problem, the hope can glad,
