在查询字符串上找不到参数

Question

I have a query string in which the parameter want this between apostrophes :

select * from myTable t
where t.name= ':name'

However when debugging the code he tells me not find the parameter :

protected bool validName(string n, NHibernate.ISession sesion){


var result= sesion.CreateSQLQuery(Queries.getQuery("queryName"))
                .SetParameter("name", n)
                .UniqueResult();

Answer 1

The Query parser should apply the sql statements for your. Try doing your query like this:

select * from myTable t where t.name = :name

I would recommend you using HQL , for sample:

var result = session.CreateQuery("from Entity t where t.name = :name")
                    .SetParameter("name", n)
                    .UniqueResult();

Where Entity is the entity that references your table (by mapping).

Answer 2

Apostrophes are used to indicate a literal string. They should and can not be used around parameter names.
