Open Plsql, execute SQL statement, Chinese display garbled:

Input SQL statement Select Userenv (' language ') from dual view database character set

Enter SQL statement SELECT * from V$nls_parameters view local character set to see if the first and nineth rows correspond

Look at the settings for the environment variable below to see if there is a variable Nls_lang, and the variable is not created

New variable, set variable name: Nls_lang, Variable value: Simplified Chinese_china. Zhs16gbk

(the variable value here needs to be the same as the database environment so it is not fixed: for example, there will be utf-8, etc.), OK

Reopen the Plsql, execute the SQL statement, and solve the problem:
