我想使用 SQL 查询获取 Oracle 中的会话数:
SELECT value FROM v$parameter WHERE name = 'sessions'
但我得到这个错误:
Error starting at line 1 in command:
SELECT value FROM v$parameter WHERE name = 'sessions'
Error at Command Line:1 Column:18
Error report:
SQL Error: ORA-00942: table or view does not exist
00942. 00000 - "table or view does not exist"
*Cause:
*Action:
也许我使用的 Oracle 用户没有特权?
