Abstract

See full text

An index is created for a database by selecting at least one column of a database table as a basis to create the index, generating at least one index of a tree structure according to the at least one column, where a pointer stored in a leaf node of the at least one index is null. In an example embodiment, a value to a pointer is stored in a leaf node according to an intermediate result in response to the intermediate result being generated, where the pointer stored in the leaf node points to a data page storing the intermediate result. The created index can be reused and the intermediate result can be effectively used, such that the efficiency of database operation is improved.
