cannot be omitted: The index does not contain one or more columns to be sorted; The order of columns in the group by or order by clause is different from that of the index; Sort columns from different tables. In order to avoid unnecessary sorting, We need to correctly add indexes and reasonably merge database tables. Although Table normalization may be affected, it is worthwhile to Improve the efficiency. If sorting is unavoidable, you should try to

database performance. Therefore, when importing data to the database, you need to select a time with a low user access volume. You also need to use appropriate means to improve the performance of data import. For example, in a DB2 database, data import tools are classified into two types: loading tools and import tools. When the imported data volume is large and users have strict performance requirements, I have established a load-using tool. General

I deleted both table a and Table B, and selected the not logged initially clause when creating the table, after creating the table, I re-import the data to table B, and finally execute the insert... select...
