You should not use quotes around the parameter name.

Parameters are automatically generated for you if your TSQLQuery has a connection assigned and ParamCheck is true and you assign TSQLQuery.CommandText.

It will not generate the parameters when you assign the query to TSQLQuery.SQL.Text.

You can have the parameters generated for you by calling TSQLQuery.Params.ParseSQL:

SQLQuery2.Params.ParseSQL(SQLQuery2.SQL.Text, True);

Or you can add them yourself by calling TSQLQuery.Params.AddParameter.
