Question

declare
user_id number(10);

begin
    if(P10_USER_TYPE = 'FACULTY') then
        user_id := :P10_BORROWER_FACULTY;
        insert into LMS_BOOK_ISSUE(BOOK_ISSUE_ID,BOOK_ID,BORROWER_ID,ISSUED_BY,BORROWED_FROM_DATE,BORROWED_TO_DATE,BORROWER_TYPE,BOOK_RT_STATUS) 
        values (LMS_BOOK_ISSUE_SEQ.nextval,**;P10_BOOK_NAME,user_id, 1, :P10_BORROWED_DATE,:P10_FACULTY_RET_DATE,'FACULTY',1** );

    update LMS_BOOK_DETAIL set BOOK_NO_OF_COPIES_CURRENT = BOOK_NO_OF_COPIES_CURRENT-1 where BOOK_ID=:P10_BOOK_NAME;

    else
        user_id := :P10_STUDENT;

我没有你的表格，所以我无法测试它，但是 - 页面项目应该在他们的名字前面用 冒号 引用，而不是分号.

DECLARE
   user_id  NUMBER (10);
