Question

Scenario is, database is in the maintenance phase. this database is not developed by ours developer. it is an existing database developed by the ‘xyz’ company in sql server 2000. This is real time database, where i am working now. I wanted to write the stored procedure which will retrieve me the records From date1 to date 2.so query is :

Select * from MyTableName
Where colDate>= '3-May-2010' and colDate<= '5-Oct-2010' and colName='xyzName'

whereas my understanding I must get data including upper bound date as well as lower bound date. but somehow I am getting records from ‘3-May-2010′ (which is fine but) to ’10-Oct-2010’

As i observe in table design , for ColDate, developer had used ‘varchar’ to store the date. i know this is wrong remedy by them. so in my stored procedure I have also used varchar parameters as @FromDate1 and @ToDate to get inputs for SP. this is giving me result which i have explained. i tried to take the parameter type as ‘Datetime’ but it is showing error while saving/altering the stored procedure that “@FromDate1 has invalid datatype”, same for “@ToDate”.

situation is that, I can not change the table design at all. what i have to do here ? i know we can use user defined table in sql server 2008 , but there is version sql server 2000. which does not support the same.
Please guide me for this scenario.

**Edited**

I am trying to write like this SP:

    CREATE PROCEDURE USP_Data  
    (@Location varchar(100),
    @FromDate  DATETIME,
    @ToDate DATETIME) AS

    SELECT     *
    FROM         dbo.TableName
    Where   CAST(Dt  AS DATETIME) >=@fromDate and  CAST(Dt  AS  DATETIME)<=@ToDate  and Location=@Location
    GO

but getting Error: Arithmetic overflow error converting expression to data type datetime. in sql server 2000
What should be that ? is i am wrong some where ? also

(202 row(s) affected) is changes every time in circular manner means first time sayin 
(122 row(s) affected)
run again saying 
(80 row(s) affected)
if again 
(202 row(s) affected)
if again 
(122 row(s) affected)

I can not understand what is going on ?

Answer 1

Can you CAST() or put a view on this table and convert all the dates to DateTime values? I can’t remember if 2000 supported index views, but based on your varchar values (dd-mmm-yyyy), it’s going to be a nightmare to try and select date rages (possible, by parsing but a pain) with those values.
