Some practical tips for using OLAP functions
The online analytical Processing,olap function is very flexible and powerful. By using these functions, you can find a simple solution for some problems that are either to iterate over one or more cursors, or to be recursive. In some other cases, it is much easier to use
My colleague asked a very simple question: how can I retrieve the minimum value of another column in each partition?
create table t1 (int c1, int c2);
If the partition is based on C2, 0-10, 10-20, 20-30, 30-40, 40-50
insert into t1 values(101, 1);insert into t1 values(102, 2);insert into t1 values(111, 11);insert into t1 values(112, 12);insert into t1 values(121, 21);insert into t1 values(122, 22);insert into t1 values(131, 31);insert into t1 values(132, 32);insert into t1 values(133,
average salary of all employees without changing the query results of the preceding statement. What should I do? It is difficult to query using common SQL statements, but using OLAP functions is very simple, as shown in the following SQL:
Select
Row_number () over () as serial number,
Row_number () over (partition by dept order by salary) as department number,
Name as name,
Dept as department,

Introduction to OLTP and OLAP
Data processing can be broadly divided into two broad categories: online transaction processing OLTP (on-line transaction processing), online analytical processing OLAP (On-line Analytical Processing). OLTP is the main application of the traditional relational database, mainly basic, daily transaction processing, such as bank transaction. O
