A small library for encapsulating data queries through IoC.
Query parameters are passed through constructor and IoC is used to populate the arguments of the Execute method.
Example of using a query through the IQueryExecutor:
bool usDuplicate = _queryExecutor.Execute(new QueryCodeEntryDuplicate(sourceQuestionIds));Example of a query class - in this case specific to :
public class QueryCodeEntryDuplicate : NHibernateQuery<bool>
{
private readonly Guid _surveyId;
private readonly string _codeListLabel;
private readonly string _matchText;
public QueryCodeEntryDuplicate(Guid surveyId, string codeListLabel, string matchText)
{
_surveyId = surveyId;
_codeListLabel = codeListLabel;
_matchText = matchText;
}
public override bool Execute(ISession session)
{
return session.Query<CodeEntry>()
.Any(x => x.SurveyId == _surveyId
&& x.CodeListLabel == _codeListLabel
&& x.MatchText == _matchText);
}
}
