java.sql.Statement is an SQL statement interface.
Description
java.sql.Statement is used for executing a static SQL statement and returning the execution results.
By default, only one ResultSet object can be open for each Statement object at a given time. Therefore, only ResultSet objects generated by different statement objects can be read in an interleaved manner. If an open ResultSet object exists, all execution methods in the Statement interface implicitly close the current ResultSet object of the statement.
