SQL LIKE problem

Hi.

I am trying to get some data from SQL database with this string:

strDate = CDate(mydate)
sql = "select NoRcpt from RcptMain where Dates LIKE '%@" & strDate & "%' order by NoRcpt DESC"

However nothing returns.

NoRcpt is Integer column (used as Identity)
Dates is Datetime column



There is data in that table, and number returned should be 1 but i am receving nothing so I guess the problem is in  Dates LIKE '%@" & strDate & "%'.

Please assist.

P.S. In string strDate looks like "14.11.2010" in database in Dates column that data is 14.11.2010. 0:00:00 that's why i am using LIKE. I could format database input to ignore hh:mm:ss but I will use that eventualy.

it is not good to use the like for date fields.
if you want to use like for date fields use the below.

select * from rcptmain where cast(dates as varchar)
like '%'+ cast(year(getdate()) as varchar)+'%'
and cast(dates as varchar) like '%'+ cast(month(getdate()) as varchar)+'%'
and cast(dates as varchar) like '%'+ cast(day(getdate()) as varchar)+'%'

othewise you can use the between stmnt

select * from rcptmain where dates between '2010-01-01 00:00' and '2010-01-30 23:59'

You should be using parameters, which will take care of formatting the date for SQL.
But since you are using a string literal, I think you want anything that is on that day regardless of time right?

strDate = CDate(mydate)
sql = "select NoRcpt from RcptMain where DateDiff(d, Dates, '" & Year(strDate) & "-" & Month(strDate) & "-" & Day(strDate) & "') = 0 order by NoRcpt DESC"
