[Mono-list] problem about "like"

[billow dragon]

hi,guys:

Now i am in this situation:I want to use the cause "like",i wrote:
string commd = "select * from buyerinfo where BuyerName like '%?blurName%'";
MySqlParameter para = new MySqlParameter("?blurName", MySqlDbType.VarChar,
45, "BuyerName");
para.Value = blurName;

It didn't work.
I changed that like this:
string commd = "select * from buyerinfo where BuyerName like
'%"+"?blurName"+"%'";
MySqlParameter para = new MySqlParameter("?blurName", MySqlDbType.VarChar,
45, "BuyerName");
para.Value = blurName;
 or:
blurName="'%"+"blurName"+"%'";
string commd = "select * from buyerinfo where BuyerName like ?blurName";
MySqlParameter para = new MySqlParameter("?blurName", MySqlDbType.VarChar,
45, "BuyerName");
para.Value = blurName;
or:
string commd = "select * from buyerinfo where BuyerName like '%?blurName%'";
MySqlParameter para = new MySqlParameter("?blurName", MySqlDbType.VarChar,
45, "BuyerName");
para.Value = blurName;

It also didn't work, when executed ,It returned nothing ,which definitely
wrong.
Any advise will be appreciated,thx!
