我将一个数组传递给一个 PL/SQL 包函数。我这样做是为了在具有 IN 子句的函数内部的查询中使用这个数组。
我的包裹声明如下:
create or replace
PACKAGE selected_pkg IS
TYPE NUM_ARRAY IS TABLE OF NUMBER;
FUNCTION get_selected_kml(
in_layer IN NUMBER,
in_id IN NUMBER,
in_feature_ids IN selected_pkg.NUM_ARRAY,
in_lx IN NUMBER,
in_ly IN NUMBER,
in_ux IN NUMBER,
in_uy IN NUMBER
)
RETURN CLOB;
END selected_pkg;
在我的 PL/SQL 函数中,我正在触发如下查询
select a.id, a.geom from Table_FIELD a where a.id in (select * from table (in_feature_ids)) and sdo_filter(A.GEOM,mdsys.sdo_geometry(2003,4326,NULL,mdsys.sdo_elem_info_array(1,1003,3), mdsys.sdo_ordinate_array(0,57,2.8,59)),'querytype= window') ='TRUE'
如果我从匿名块运行相同的查询,例如
CREATE TYPE num_arr1 IS TABLE OF NUMBER;
declare
myarray num_arr1 := num_arr1(23466,13396,14596);
BEGIN
FOR i IN (select a.id, a.geom from Table_FIELD a where a.id in (select * from table (myarray)) and sdo_filter(A.GEOM,mdsys.sdo_geometry(2003,4326,NULL,mdsys.sdo_elem_info_array(1,1003,3), mdsys.sdo_ordinate_array(0,57,2.8,59)),'querytype= window') ='TRUE'
loop
dbms_output.put_line(i.id);
end loop;
end;
如果我尝试通过调用如下函数来运行它
--Running function from passing array for IDs
declare
result CLOB;
myarray selected_pkg.num_array := selected_pkg.num_array(23466,13396,14596);
begin
result:=SELECTED_PKG.get_selected_kml(3, 19, myarray, 0.0,57.0,2.8,59);
end;
我收到错误
ORA-00904: "IN_FEATURE_IDS": invalid identifier
有人可以帮我理解它的原因吗?
谢谢,艾伦
