爲什麼我得到這個語句的下面的錯誤?單行子查詢在執行語句中返回多個錯誤
DECLARE COL_COUNT NUMBER;
BEGIN
COL_COUNT :=0;
SELECT COUNT(1) INTO COL_COUNT FROM USER_OBJECTS WHERE OBJECT_NAME = 'P_TEST' AND OBJECT_TYPE = 'PROCEDURE';
IF COL_COUNT = 0 THEN
EXECUTE IMMEDIATE ('CREATE or replace PROCEDURE P_TEST IS BEGIN null; END;');
END IF;
END;

@a_horse_with_no_name我po作爲一個圖像,所以你可以更清楚地理解錯誤,也可以添加我的代碼。至於我的代碼,我正在創建一個過程,我沒有做一個選擇,所以我可以得到幾個結果 – Moudiz
我不認爲代碼會提供此錯誤。 – hemalp108
