> Parameters added to an HQL query are jumbled in the resulting SQL. I have created a simple test case that demonstrates this problem using the BasicClassFixture:
> [Test]
> public void TestHQL()
> {
>     var bc = InsertBasicClass(1);
>     using (var session = OpenSession())
>     using (var trans = session.BeginTransaction())
>     {
>         var hql = "from BasicClass bc where (bc.StringProperty = :prop) and (bc.StringMap[:key] = :value)";
>         bc = session.CreateQuery(hql)
>             .SetParameter("prop", "string property")
>             .SetParameter("key", "keyZero")
>             .SetParameter("value", "string zero")
>             .UniqueResult<BasicClass>();
>         Assert.NotNull(bc);
>         session.Delete(bc);
>         trans.Commit();
>     }
> }
> The generated SQL is:
> exec sp_executesql N'select basicclass0_.id as id16_, basicclass0_.char_p as char2_16_, basicclass0_.class_p as class3_16_, basicclass0_.cinfo_p as cinfo4_16_, basicclass0_.dtm_p as dtm5_16_, basicclass0_.shrt_p as shrt6_16_, basicclass0_.int_p as int7_16_, basicclass0_.lng_p as lng8_16_, basicclass0_.flt_p as flt9_16_, basicclass0_.str_p as str10_16_, basicclass0_.ticks_p as ticks11_16_, basicclass0_.tf_p as tf12_16_, basicclass0_.yn_p as yn13_16_, basicclass0_.priv_fld as priv14_16_ from bc basicclass0_, bc_stmap stringmap1_ where basicclass0_.id=stringmap1_.bc_id and stringmap1_.strm_idx = @p0 and basicclass0_.str_p=@p1 and stringmap1_.str_val=@p2',N'@p0 nvarchar(4000),@p1 nvarchar(10),@p2 nvarchar(4000)',@p0=N'string property',@p1=N'keyZero',@p2=N'string zero'
> This query returns no rows when it should return exactly one. This is because @p0 and @p1 have been swapped.
