Question

我是存储过程的新手，我创建了这个光标，它将在每晚的午夜运行，如果没有停止，则翻转最后几天的记录。执行时我每次都会收到错误。我不确定是什么造成的。任何帮助将非常感激。

消息102，级别15，状态1，程序nt_rollover_charge，第38行 'nt_cursor'附近的语法不正确。

CREATE PROCEDURE nt_rollover_charge
AS
  BEGIN
      SET NOCOUNT ON;

      DECLARE @id VARCHAR(20);
      DECLARE nt_cursor CURSOR FOR
        SELECT DISTINCT log_id
        FROM   log_book
        WHERE  test_id = '3'
               AND nt_dc_status = 'FALSE'
               AND nt_current_date = 'TRUE';

      OPEN nt_cursor

      FETCH NEXT FROM nt_cursor INTO @id

      WHILE @@FETCH_STATUS = 0
        BEGIN
            UPDATE log_book
            SET    nt_current_date = 'False'
            WHERE  log_id = @id

            INSERT INTO log_book
                        (mrn,
                         fin,

            -- This is executed as long as the previous fetch succeeds.
            FETCH NEXT FROM nt_cursor INTO @id
        END

      CLOSE nt_cursor

      DEALLOCATE nt_cursor
  END

首先，您不应该使用游标，因为这会破坏使用SQL和数据库的目的，这是基于集合的操作。只需写下你的陈述：

Update Log_book set
nt_current_date = 'False'
from
Log_book inner join
Log_book L2
on L2.log_id = log_book.log_id
where
L2.test_id = '3' and  L2.nt_dc_status = 'FALSE';

INSERT INTO log_book(mrn, fin, ref_dr, tech, equip_id, hookup_id, indication,     abnormality, location_id, test_id, charged, start_date, nt_rollover_date, nt_dc_status,     nt_current_date)
SELECT  log_book.mrn, log_book.fin, log_book.ref_dr, log_book.tech, log_book.equip_id, log_book.hookup_id, log_book.indication,     log_book.abnormality, log_book.location_id, log_book.test_id, null, log_book.start_date, getdate(), 'FALSE', 'TRUE'
            FROM log_book 
inner join
Log_book L2
on L2.log_id = log_book.log_id
where
L2.test_id = '3' and  L2.nt_dc_status = 'FALSE';

至于您的实际问题，您发布的内容只有33行，但错误发生在第38行。您的存储过程结束时是否有END语句？
