oracle 在立即执行中返回 ID 给出 "missing keyword" 错误
oracle returning ID in execute immediate giving "missing keyword" error
以下是oracle程序
create or replace
PROCEDURE INSERT_COMMON(
ENTITY_NAME IN VARCHAR2
, INSERT_QUERY IN varchar2
)
AS
NEW_ID NUMBER;
BEGIN
-- execute insert
DBMS_OUTPUT.PUT_LINE('INSERT_QUERY: ' || INSERT_QUERY);
-- execute IMMEDIATE INSERT_QUERY returning ID into NEW_ID;
-- above gives me a syntax error so using as below
execute IMMEDIATE INSERT_QUERY || ' returning ID into NEW_ID';
DBMS_OUTPUT.PUT_LINE('NEW_ID: ' || NEW_ID);
END INSERT_COMMON;
和Pl/SQL我正在使用
DECLARE
ENTITY_NAME VARCHAR2(200);
INSERT_QUERY VARCHAR2(200);
BEGIN
ENTITY_NAME := 'company';
INSERT_QUERY := 'INSERT INTO COMPANY (NAME) VALUES (''A Company 2'')';
INSERT_COMMON(ENTITY_NAME,INSERT_QUERY);
END;
这给了我以下错误
Error report:
ORA-00905: missing keyword
ORA-06512: at "SYSTEM.INSERT_COMMON", line 20
ORA-06512: at line 8
00905. 00000 - "missing keyword"
不过,我已经测试过,下面的工作正常
DECLARE
NEW_ID NUMBER;
BEGIN
INSERT INTO COMPANY (NAME) VALUES ('A Company 2') returning ID into NEW_ID;
DBMS_OUTPUT.PUT_LINE('NEW_ID: ' || NEW_ID);
END;
您需要在动态 sql 语句中指定要返回的绑定变量,但您还需要将 returning into <variable>
子句添加到立即执行语句。
我相信(未经测试,因为您没有提供设置 table 和相关触发器的语句)以下应该可以解决您的问题:
create or replace procedure insert_common (entity_name in varchar2,
insert_query in varchar2)
as
new_id number;
begin
-- execute insert
dbms_output.put_line ('INSERT_QUERY: ' || insert_query);
-- above gives me a syntax error so using as below
execute immediate insert_query || ' returning ID into :NEW_ID' returning into new_id;
dbms_output.put_line ('NEW_ID: ' || new_id);
end insert_common;
