In Oracle, there are many ways to implement paging using SQL, but some statements may not be very common and can only be used in some special scenarios. The following describes three general implementation solutions; in the following implementations, ROWNUM is the core keyword. During a query, ROWNUM is a virtual column. The value ranges from 1 to the serial number of the total number of records. In

Sequence. Drop sequence order_seq; A simple example: Create sequence SEQ_ID Minvalue 1 Max value 99999999 Start with 1 Increment by 1 Nocache Order; The code of the producer is: Create or replace trigger tri_test_id Before insert on S_Depart -- S_Depart is the table name. For each row Declare Nextid number; Begin IF: new. DepartId IS NULLor: new. DepartId = 0 THEN -- DepartId IS the column name. Select SEQ_ID.nextval -- SEQ_ID is just created Into nextid From sys. dual; : New. DepartId: = nexti

The interconnection of different database platforms is generally called the heterogeneous service of databases. Currently, all major databases can achieve such Heterogeneous Interconnection, but the specific implementation technologies of different vendors are different, such: in SYBASE, it is called connect or connection profile, and ODBC is used to interconnect with other databases. The test environment in this article is: Operating System: WINDOWS2
