Abstract
A computer-implemented database access method includes receiving, by a server, a database access statement including a target identifying parameter; parsing the database access statement to determine the target identifying parameter; determining a statement type of the database access statement; obtaining a pre-stored execution plan group corresponding to the statement type, the pre-stored execution plan group including one or more execution plans for accessing a database corresponding to the database access statement, in which each execution plan corresponds to a different respective identifying parameter; selecting a target execution plan from the pre-stored execution plan group based on the target identifying parameter; and executing the target execution plan.
