Hi all,

I'm trying to tweak some code in the DAL2 to use "like" in the where clause, like this:

select * from table where LastName like '%mark%'

Here's some code I copied and tweaked using a where clause to get some records but I can't figure out how to use "like" using a parameter passed in to a method:

IEnumerable t;
using (IDataContext ctx = DataContext.Instance())
{
var rep = ctx.GetRepository();
t = rep.Find("WHERE [email protected]", strLastName);
}

It works fine if the variable strLastName matches exactly but I'd like to find similiar matches too.

Thanks,
Mark

did you try to put ' around the text to compare with?

Instead of hoping we can guess why not tell us what you DID do and how it failed?

I tried no quotes, single quotes, and the % symbol did it complained about a foreign character but I just got it to work by builing the where clause dynamically like this:

string strWhere = "WHERE FirstName like '%" + strPhrase + "%'";

And using it like this:

t = rep.Find(strWhere, strPhrase);

Mark, that's exactly, how It should look like for the sql server;
rep.Find("WHERE FirstName Like '%@0%'", strLastName)
