不断出现错误：PLS-00103：遇到符号“CREATE”

Question

我在 Oracle SQL Developer 中收到以下错误

PLS-00103：遇到符号“CREATE”

CREATE OR REPLACE PROCEDURE EnrollStudent(
     p_StudentID IN INT,  
    p_CourseID IN INT   
) IS

    v_student_skill INT;
    v_course_skill INT;
    v_enrolled_count INT;
    
BEGIN
    SELECT skill INTO v_student_skill
    FROM A1_Student
    WHERE StudentID = p_StudentID;

    SELECT skill INTO v_course_skill
    FROM A1_Course
    WHERE CourseID = p_CourseID;

    IF v_student_skill < v_course_skill THEN
        RAISE_APPLICATION_ERROR(-20001, 'Student skill level is not sufficient for this course.');
    END IF;

    SELECT COUNT(*) INTO v_enrolled_count
    FROM A1_Enrollment
    WHERE StudentID = p_StudentID AND CourseID = p_CourseID;

    IF v_enrolled_count > 0 THEN
        RAISE_APPLICATION_ERROR(-20002, 'Student is already enrolled in this course.');
    END IF;

    INSERT INTO A1_Enrollment (StudentID, CourseID)
    VALUES (p_StudentID, p_CourseID);

    COMMIT;
    DBMS_OUTPUT.PUT_LINE('Student successfully enrolled in the course.');
EXCEPTION
    WHEN NO_DATA_FOUND THEN
        DBMS_OUTPUT.PUT_LINE('Student or Course not found.');
    WHEN OTHERS THEN
        
        ROLLBACK;
        DBMS_OUTPUT.PUT_LINE('Error: ' || SQLERRM);
END EnrollStudent;
/

不完全确定为什么会出现此错误，任何帮助将不胜感激。

我将您的代码复制到 SQL Developer 工作表中，运行它并且...

Procedure ENROLLSTUDENT compiled

LINE/COL  ERROR
--------- -------------------------------------------------------------
11/5      PL/SQL: SQL Statement ignored
12/10     PL/SQL: ORA-00942: table or view does not exist
15/5      PL/SQL: SQL Statement ignored
16/10     PL/SQL: ORA-00942: table or view does not exist
23/5      PL/SQL: SQL Statement ignored
24/10     PL/SQL: ORA-00942: table or view does not exist
31/5      PL/SQL: SQL Statement ignored
31/17     PL/SQL: ORA-00942: table or view does not exist
Errors: check compiler log

程序编译完成。有错误，但编译通过。出现错误是因为我没有任何这些表。

然后我将以下代码放在我粘贴的代码之前。请注意，这是一个不完整的 pl/sql 代码块。它缺少尾随“/”。

BEGIN
  NULL;
END;

并再次运行整个过程。现在的错误是...

...
Error report -
ORA-06550: line 4, column 1:
PLS-00103: Encountered the symbol "CREATE" when expecting one of the following:
...

所以，很可能您在

CREATE OR REPLACE

之前还有一些其他不完整的陈述
