How do I find out when a stored procedure was last modified or compiled in Oracle?

由 前提是你 提交于 2019-12-02 20:33:44
I'm preferably looking for a SQL query to accomplish this, but other options might be useful too. SELECT LAST_DDL_TIME, TIMESTAMP FROM USER_OBJECTS WHERE OBJECT_TYPE = 'PROCEDURE' AND OBJECT_NAME = 'MY_PROC'; LAST_DDL_TIME is the last time it was compiled. TIMESTAMP is the last time it was changed. Procedures may need to be recompiled even if they have not changed when a dependency changes. SELECT name, create_date, modify_date FROM sys.procedures order by modify_date desc Following query will do in Oracle SELECT * FROM ALL_OBJECTS WHERE OBJECT_NAME = 'OBJ_NAME' ; 来源： https://stackoverflow.com

If not, what is the command to delete all the tablespace / datafiles / disk space that were used by that particular user.

For example if you had a user named 'SAMPLE' and two tablespaces called 'SAMPLE' and 'SAMPLE_INDEX', then you'd need to do the following: DROP USER SAMPLE CASCADE; ALTER TABLESPACE SAMPLE OFFLINE; DROP TABLESPACE SAMPLE INCLUDING
