我正在尝试创建一个函数,它将从几个表中返回一行包含多个计数.这是我到目前为止所拥有的:
CREATE OR REPLACE TYPE RESULT_ROW is OBJECT
(LOC_TABLE_ENTRY_KY VARCHAR2(50),
LOCATION_NAME VARCHAR2(50),
A_ASSIGN_CNT VARCHAR2(50),
B_ASSIGN_CNT VARCHAR2(50),
C_ASSIGN_CNT VARCHAR2(50),
D_ASSIGN_CNT VARCHAR2(50),
E_ASSIGN_CNT VARCHAR2(50),
F_ASSIGN_CNT VARCHAR2(50),
G_ASSIGN_CNT VARCHAR2(50),
H_ASSIGN_CNT VARCHAR2(50));
/
CREATE OR REPLACE TYPE RESULT_TABLE AS TABLE OF RESULT_ROW;
/
CREATE OR REPLACE FUNCTION LOCATION_RULE_LOOKUP(P_LOCATION_VAR IN NUMBER)
RETURN RESULT_TABLE
IS
OUT_REC RESULT_TABLE;
BEGIN
WITH LOC AS
(SELECT LOC_TABLE_ENTRY_KY,
LOCATION_NAME
FROM LOCATION_CODE
WHERE LOC_TABLE_ENTRY_KY = P_LOCATION_VAR
),
ONE AS
(SELECT COUNT(*) AS A_ASSIGN_CNT
FROM COLLECTOR_ASSIGNMENT
WHERE LOCATION_CODE = P_LOCATION_VAR
AND …
