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

How to use Oracle External tables to import data from text files, oracle Text Files Recently, colleagues are busy with Data Consistency comparison.

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
