; End loop; CLOSE c_temp; END; Method 2: insert into hr. job_history Copy codeThe Code is as follows:Select * from hr. job_history as of timestamp to_timestamp ('2017-07-23 10:20:00 ', 'yyyy-mm-dd hh24: mi: ss '); This method is simple and easy to grasp. The function is the same as the above time as the time before your misoperation, preferably close to the misoperation, because the time limit for oracle data stored in the rollback persistence segment

Analysis on the storage format of Oracle nested tables and oracle nesting Oracle nested tables are rarely used. The following describes how to store them. For example, a user corresponds to a department. SQL> select * from v $ version;BANNER----------------------------------

How to Create tablespaces and users in oracle and create tables in oracle1. First, if a user exists Drop user username cascade; 2. if it cannot be deleted, the current user may be in the connection status. You can find the session Select username, sid, serial # from v $ session where username = username; Alter system kill session 'sid, serial #' 3. If you want to be safe, lock the current user first; Alter

Summary of basic table space management operations in Oracle databases, tables in oracle DB storage hierarchy (I drew a sketch and I will take a look at it... XD) Manage tablespaces -System: required to store data dictionary information. It is the first database to be created. -New and required 10 Gb sysaux, which helps to share system load, system management, o

stores two or more tables in a single unit cluster 3. Under what circumstances is a clustered table used? Single-table clustering solves large scale data processing in massive database. The composite clustering greatly improves the efficiency of the specific table connection. Clustering plays a great role in improving the efficiency of data reading, but the cost of inserting, modifying and deleting data is relatively large. The most important th

In Oracle8i or later versions, you can create the following two types of temporary tables: 1. Session-Specific temporary tables CREATE GLOBAL Temporary On COMMIT PRESERVE ROWS; 2. Transaction-specific temporary tables CREATE GLOBAL Temporary On COMMIT DELETE ROWS;CREATE GLOBAL Temporary TABLE mytemptable Although the temporary table is in existence, but you

Oracle uses a cursor to add a primary key statement to all user tables. oracle cursor Application Scenario: adding an auto-increment primary key to a data table can speed up data table access, and is the fastest in integer indexing. This program is suitable for running when the Oracle database is imported and the prima

Label: --table backups in the Oracle database: --BACKUP statement: After the backup, you can delete all the data sources for this table, but then someone will manipulate the table's data, but remember to restore the data table after the operation is complete.

Oracle uses a cursor to delete all record scripts in all user data tables. oracle cursor Application Scenario: because the data in the database involves confidential information, we hope to delete all the data at a time and only keep the data table structure for the development of new projects. Test Result: All data has been deleted. Problem: if the data table ha

Although we often use temporary tables in daily database development and maintenance, we may still have a poor understanding of temporary tables. I found a good post on the Internet today to share with you. Source: http://www.matrix.org.cn/thread.shtml?

Space occupied by ORACLE computing tables and space occupied by oracle In ORACLE databases, how does one calculate the storage space occupied by a table? You can view the space occupied by a table in the System View DBA_SEGMENTS, USER_SEGMETNS, and DBA_TABLES, as shown below: SELECT SEGMENT_NAME TABLE_NAME ,SUM(
