Parameterizing an SQL IN clause?

Anonymous User285417-Apr-2013
Hi All!

How do I parameterize a query containing an IN clause with a variable number of arguments, like this one?

select * from Tags 
where Name in ('ruby','rails','scruffy','rubyonrails')
order by Count desc
In this query, the number of arguments could be anywhere from 1 to 5.

I would prefer not to use a dedicated stored procedure for this (or XML), but if there is some fancy SQL Server 2008 specific way of doing it elegantly, I am open to that.

Thanks in advance!

Hi Chintoo!

select * from Tags
where '|ruby|rails|scruffy|rubyonrails|'
like '%|' + Name + '|%'
So here's the C# code:

string[] tags = new string[] { "ruby", "rails", "scruffy", "rubyonrails" };
const string cmdText = "select * from tags where '|' + @tags + '|' like '%|' + Name + '|%'";

using (SqlCommand cmd = new SqlCommand(cmdText)) {
   cmd.Parameters.AddWithValue("@tags", string.Join("|", tags);
}
