我正在使用 SQL Server 2008 R2 我有这样的存储过程：

CREATE PROCEDURE Get_Code_Tourne_Matin
    -- Add the parameters for the stored procedure here
@The_FA int,
@The_Jour int,
@The_Insee varchar(10)
AS
BEGIN
declare @TheCode varchar(250)


set @TheCode = case
    when exists (SELECT T_TOURNE_LABEL.LIBELLE 
                  FROM TOURNE
                  LEFT JOIN T_TOURNE_LABEL ON TOURNE.LIB_TOURNE = T_TOURNE_LABEL.NOID
                  WHERE THE_FA = @The_FA AND 
                        NO_INSEE = @The_Insee AND 
                        JOUR = @The_Jour AND 
                       (datepart(hh, LE_HEURE) between 13 and 23 or datepart(hh, LE_HEURE) between 0 and 6)) then LIBELLE
    when exists (SELECT LIBELLE
                  FROM TOURNE
                  LEFT JOIN T_TOURNE_LABEL ON TOURNE.LIB_TOURNE = T_TOURNE_LABEL.NOID
                  WHERE THE_FA = @The_FA AND 
                        NO_INSEE = @The_Insee AND 
                        JOUR = 0 AND 
                       (datepart(hh, LE_HEURE) between 13 and 23 or datepart(hh, LE_HEURE) between 0 and 6)) then LIBELLE
    else '00'


    end


RETURN @TheCode  
END

我只想归还诽谤。
找到第一个带有 3 个变量的选择，然后重新运行 libelle
else 如果找到运行带有 2 个变量的选择，然后重新运行 libelle
else retrun '00'

LIBELLE 似乎有语法错误

任何的想法 ？

我认为是这样的：

set @TheCode = COALESCE(
(SELECT TOP 1 T_TOURNE_LABEL.LIBELLE 
                  FROM TOURNE
                  LEFT JOIN T_TOURNE_LABEL ON TOURNE.LIB_TOURNE = T_TOURNE_LABEL.NOID
                  WHERE THE_FA = @The_FA AND 
                        NO_INSEE = @The_Insee AND 
                        (JOUR = @The_Jour OR JOUR = 0) AND 
                       (datepart(hh, LE_HEURE) between 13 and 23 or datepart(hh, LE_HEURE) between 0 and 6)
ORDER BY JOUR DESC), '00')

应该涵盖你所有的情况。（如果您的查询中永远不可能有两个匹配的行，一个 hasJOUR = @The_Jour另一个 has JOUR = 0，那么您可以删除TOP 1andORDER BY子句（请注意，我假设任何可能的@The_Jour值都大于 0）
