Temporary tables, external tables, and partition tables in OracleTemporary table In Oracle, a temporary table is "static". It only needs to be created once like a common data table. Its structure is valid from creation to deletion. Compared with other types of tables, a temporary table allocates space only when you add

1. What is joinJoin: Join indicates the relationship between two tables. we can regard two tables as two sets. Suppose there are two tables, which are represented by a and B.

So I tried to write the following query:Result1(Select distinct UsernameFrom logWhere logtime> =
