The Lag and Lead functions can retrieve the data of the first N rows and the value of the last N rows of the same field in a query. This operation can be achieved through table join for the same table, but LAG and LEAD are more efficient. Copy codeThe Code is as follows: create table salaryByMonth ( EmployeeNo varchar2 (20 ), YearMonth varchar2 (6 ), Salary number ); Insert into SALARYBYMONTH (EMPLOYEENO, YEARMONTH, SALARY) Values (1, '20140901', 200805 ); Insert into SALARYBYMONTH (EMPLOYEENO,

1 IntroductionIn the process of programming, you will often encounter two sets of records compared. such as the East China power grid PMS interface to implement the transfer of changes (new, modified, deleted) in the day of data.
