SQL2000 参数太长了,该如何解决

SQL2000 参数太长了
Declare @Command Varchar(2000) 
SET @PN80=''''+@PN80+''''
SET @PN80=replace(@PN80,',',''',''')
SET @Command='SELECT Customer,PN80,PN AS PN52,Dosage as Usage,Flow,Line,Hours,OutPutQty FROM HOURSSMT WHERE PN80 IN ('+@PN80+')'
EXEC(@Command)

这个@PN80有时候会非常的长，也就是字符串很长，这条SQL语句就报错了，不知道有什么解决办法呢，

------解决方案--------------------
Declare @Command Varchar(8000) SET @PN80=''''+@PN80+''''
SET @PN80=replace(@PN80,',',''',''')
SET @Command='SELECT Customer,PN80,PN AS PN52,Dosage as Usage,Flow,Line,Hours,OutPutQty FROM HOURSSMT WHERE PN80 IN ('+@PN80+')'
EXEC(@Command)


------解决方案--------------------

MSSQL2000不能那么写，的分开
@PN80 VARCHAR(MAX)
set @PN80=''
2008当中可以你那么写

给他设为varchar(max)试试，不够的话就换类型
