查询不会通过过程显示结果

使用sql server 2005 DB中的存储过程,过程有一段查询

.
.
.


if(@zipCodeList <> '')
BEGIN
    SET @zipCodeList = ''''+replace(replace(replace(@zipCodeList, ' ', ''),',',''','''),'_',' ')+''''
END 

SELECT distinct ZIPCode
from zip_table
where ZIPCode_col  IN (@zipCodeList)
AND power((69.1 * (abs(Longitude) - abs(Longitude)) * cos(abs(Latitude)/57.3)),2) +
Power(69.1 * (abs(Latitude) - abs(Latitude)), 2) <= (60 * 60)
AND more conditions 
.
.
.

调用类似

的过程
exec proc '02124, 23568'

数据库有记录,但程序没有显示任何内容,我打印了查询并打印

SELECT distinct ZIPCode
from zip_table
where ZIPCode_col  IN ('02124','23568')
AND power((69.1 * (abs(Longitude) - abs(Longitude)) * cos(abs(Latitude)/57.3)),2) +
Power(69.1 * (abs(Latitude) - abs(Latitude)), 2) <= (60 * 60)
AND more conditions

当我运行此查询时,返回正确的结果。看起来像@zipCodeList在运行时引起了一些问题,但没有给出任何错误,任何人都可以在我错误的地方帮助我。

提前致谢。

如果@zipCodeList的值为1,2,3,则执行以下代码

SELECT distinct ZIPCode
from zip_table
where ZIPCode_col  IN 
(
    SELECT PARSENAME(REPLACE(Split.a.value('.', 'VARCHAR(500)'),'-','.'),1) 'Ids' 
    FROM  
    (
         SELECT CAST ('<M>' + REPLACE(@zipCodeList, ',', '</M><M>') + '</M>' AS XML) AS Data       
    ) AS A 
    CROSS APPLY Data.nodes ('/M') AS Split(a)
)
AND power((69.1 * (abs(Longitude) - abs(Longitude)) * cos(abs(Latitude)/57.3)),2) +
Power(69.1 * (abs(Latitude) - abs(Latitude)), 2) <= (60 * 60)
AND more conditions
