Question

CREATE OR REPLACE procedure sp_tab is
    id1 number:=0;
begin
  select nvl(max(id1), 0) + 1 
    into id1 
    from DUAL;
  insert into table1
       SELECT distinct id1, '', SUBSTR(PRODUCT, 0, INSTR(PRODUCT, ' ') - 1), '' 
         FROM table2 
        WHERE PRODUCT NOT IN ('proved product', 'sample', 'graphic era', 'asa');
end;

从表'table2'在表'table1'中插入id的Creatin过程使用过程，但它显示匿名行为。

Answer 1

创建如下序列：

create sequence id1 start with 1 increment by 1;

在您的代码中使用它，如下所示：

CREATE OR REPLACE PROCEDURE sp_tab
IS 
BEGIN

   INSERT INTO table1
      SELECT id1.nextval,
                      '',
                      SUBSTR (PRODUCT, 0, INSTR (PRODUCT, ' ') - 1),
                      ''
        FROM table2
       WHERE PRODUCT NOT IN ('proved product',
                             'sample',
                             'graphic era',
                             'asa');


END;

如何在oracle 11g中插入id自动增量？
