在 Cursor 中动态查询 %rowtype
Dynamic query in Cursor for %rowtype
我需要创建一个记录类型来包含上述
查询的结果集
V_SQL VARCHAR2(200) := 'SELECT T1.'||record_id||',T1.'||card_no||',T2.TEST_CARD_NO, T1.'||type_cc||' FROM '|| table_name||' T1
INNER JOIN TEST T2 ON
T2.ID = T1.'||record_id;
这样我就可以在循环执行语句
中使用 t1 C_BRNGB_EXTRACT%ROWTYPE(在 l_BRNGB_EXTRACT 内为 t2.col4%TYPE 加上另一列)
CREATE OR REPLACE PROCEDURE "GCCPMAINT"."FUNCTION_CURSOR"(table_name VARCHAR2,record_id VARCHAR2,card_no VARCHAR2,type_cc VARCHAR2)
AS
limit_in NUMBER:=100;
V_SQL VARCHAR2(200) := 'SELECT T1.'||record_id||',T1.'||card_no||',T2.TEST_CARD_NO, T1.'||type_cc||' FROM '|| table_name||' T1
INNER JOIN TEST T2 ON
T2.ID = T1.'||record_id;
TYPE BRNGB_EXTRACT IS REF CURSOR;
C_BRNGB_EXTRACT BRNGB_EXTRACT;
TYPE BRNGB_EXTRACT1 IS TABLE OF C_BRNGB_EXTRACT%ROWTYPE;
l_BRNGB_EXTRACT BRNGB_EXTRACT1;
BEGIN
OPEN C_BRNGB_EXTRACT FOR V_SQL;
LOOP
FETCH C_BRNGB_EXTRACT BULK COLLECT INTO l_BRNGB_EXTRACT LIMIT limit_in;
EXIT WHEN l_BRNGB_EXTRACT.COUNT = 0;
FORALL indx IN 1 .. l_BRNGB_EXTRACT.COUNT
EXECUTE IMMEDIATE 'UPDATE table_name SET CARD_NO=:1 WHERE CARD_NO=:2 AND RECORD_ID=:3' USING l_BRNGB_EXTRACT(indx).test_card_no,l_BRNGB_EXTRACT(indx).CARD_NO,l_BRNGB_EXTRACT(indx).RECORD_ID;
END LOOP;
CLOSE C_BRNGB_EXTRACT;
COMMIT;
END;
对于上述存储过程,我收到以下错误
PLS-00320: the declaration of the type of this expression is
incomplete or malformed PL/SQL: Item ignored PLS-00597: expression
'L_BRNGB_EXTRACT' in the INTO list is of wrong type PL/SQL: SQL
Statement ignored PLS-00487: Invalid reference to variable
'C_BRNGB_EXTRACT%ROWTYPE'
请帮我解决这个问题。
我得到了解决方案
