Abstract

See full text

In an embodiment, a first query is received that specifies a first object identifier. If a first query plan exists that implements the first query, except that the first query plan does not comprise the first object identifier and instead comprises a parameter marker in place of the first object identifier, a first query execution plan is created from the first query plan, substituting the first object identifier in the first query execution plan for the parameter marker, and the first query execution plan is executed to read a first object identified by the first object identifier.
