Question

How can I specify the length of string input parameters of a stored procedure in Nhibernate mapping files.

this is my mapping contents

<sql-query name="Sp_News" resultset-ref="NewsPackResultSet" cacheable="false">

    <query-param name="SearchString"       type="System.String" />
    <query-param name="StartDate"          type="System.DateTime" />

          exec dbo.Sp_News:SearchString,:StartDate

</sql-query>

When the length of SearchString parameter is more than 4000 characters, the Nhibernate Truncates that parameter values. How can i solve this limitation?

any help would be appreciated.

Found this question and also found the answer:

IQuery query = session.GetNamedQuery("Sp_News");
query.SetParameter("SearchString", longString, NHibernateUtil.StringClob);

NHibernateUtil.StringClob is the key 🙂
