Question

我为部门编号（10,20,30）创建了具有列表样式（Poplist）的ListItem1，为员工名称创建了具有列表样式（Tlist）的其他ListItem2。员工姓名记录组

当我单击10号部门时，然后将所有员工姓名数据填充到ListItem2中。我只想填充属于部门10或20或30的雇员姓名的数据

代码：

DECLARE

a VARCHAR2(100);
num NUMBER := 10;

BEGIN

a := populate_group ('R1');
    populate_list ('LIST1','R1');

END;

“ LIST1” 用于填充员工姓名数据 “ R1” 是组记录名称

Answer 1

在PL / SQL中，列表称为集合。

尝试类似的方法：

DECLARE
  TYPE population_type IS TABLE OF NUMBER INDEX BY VARCHAR2(64);
  country_population population_type;
  continent_population population_type;
  howmany NUMBER;
  which VARCHAR2(64)

BEGIN
  country_population('Greenland') := 100000;
  country_population('Iceland') := 750000;
  howmany := country_population('Greenland');

  continent_population('Australia') := 30000000;
  continent_population('Antarctica') := 1000; -- Creates new entry
  continent_population('Antarctica') := 1001; -- Replaces previous 
value
  which := continent_population.FIRST; -- Returns 'Antarctica'
-- as that comes first alphabetically.
  which := continent_population.LAST; -- Returns 'Australia'
  howmany := continent_population(continent_population.LAST);
-- Returns the value corresponding to the last key, in this
-- case the population of Australia.
END;

Answer 2

听起来像您只需要向R1记录组添加where department_no = :List1。

如何将数据库中的特定数据填充到列表项中？
