How can I display pl/SQL query data in Chinese?

How can I display pl/SQL query data in Chinese? Solution: 1. Open the installation directory of PLSQL Developer, see the directory of plsqldev.exe, create the "PLSql_run.bat" file in the PLSQL Developer folder, and enter the following content in the file:

Please set nls_lang = SIMPLIFIED CHINESE_CHINA.ZHS16GBKPLSQLDev.exe cute ---------------------------------------------------------------------------------------------

 

2. Use the PLSql_run.bat file to start the PLSQL Developer tool each time you start the tool. Otherwise, garbled characters may occur. Using the above method, I tried to access a table containing Chinese Characters Under sqlplus and correctly display the Chinese content of the field. Open cmd

> Set nls_lang = SIMPLIFIED CHINESE_CHINA.ZHS16GBK> sqlplus/nolog> conn study/study @ orcl> select * from staff_number;
