Question

SELECT DateDiff("n", LastDate, Now()) as datediffs FROM UserLog WHERE ID = 1

When I execute this query from Query Design View (MS Access). This give me different in minutes well like this:

datediffs
---------
2826

But when I execute the same query (including static value in where condition ID = 1) from servlet like this:

strSql = "SELECT DateDiff(\"n\", LastDate, Now()) as datediffs FROM UserLog WHERE ID = 1";
recset=stmt.executeQuery(strSql);

It gives me the following error:

[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected
1.

So what wrong with me?

Write-up of comments from above.

If

SELECT TOP 5 id, lastdate FROM UserLog 

runs, then you need to look at the various other parts of your statement. For example, Now() can cause a problem if the database has lost references.

However, you report

I executed SELECT DateDiff("n", LastDate, ’20-08-2012 5:15:10 PM’)
Which did not executed. When I tried this one SELECT LastDate, NOW()
FROM … it was executed successfully. So I suspect the problem is
with Datediff() function. (–- @hims056, OP)

Which is odd, because DateDiff notmally works outside of MS Access. However, I notice that this problem is reported in Oracle Bugs. In the comments, one person mentions that in his or her case, the problem was a misnamed column, so it may be possible to use ACE, rather than Jet for the connection. Alternatively, as you say, "get datediff in minutes from Java."
