In below code, if(_drone["CODE"] =="zen") inside the for loop is not working,eventhough _drone["code"] contain zen.
Only those records with value zen .nedd to be added to_dr (_abc.rows.ans(_dr)
public DataTable InitInGroup(DataTable _dtdoctor, string _Folio, string _IsCom = "No", string _CODE = "")
{
DataTable _abc = GetDoc("~", "~", "~", "~");
if (_dtdoctor != null)
{
foreach (DataRow _drone in _dtdoctor.Rows)
{
if (_drone["CODE"] == "zen"
Edit
Not working with the one you mentioned .As above another scenario stated below.I want to compare the session value with the database value
foreach (DataRow dr28 in _DTU_ABC.Rows)
{
string ss = HttpContext.Current.Session["ADMIN"].ToString();
IF (dr28[_CODE].ToString == ss)
{
cmd28.Parameters.Clear();
OracleHelper.CreateParameter(ref cmd28, ref param28, "#NUMBER", DbType.String, ParameterDirection.Input, dr28["Number"].ToString());
OracleHelper.CreateParameter(ref cmd28, ref param28, "#SITECODE", DbType.String, ParameterDirection.Input, dr28["CODE"].ToString());
cmd28.ExecuteNonQuery();
}
}
_drone["CODE"] returns an object. Try this instead:
if (_drone["CODE"].ToString() == "zen")

I'm new to this and this is my first question.
So far I have this, but it takes a long time to get the record:
public string BuscarPedimento(string patente, string pedimento2, string aduana)
{
using (var context = new DataStage3Context())
{
DsPedimentos pedimento = context.DsPedimentos.FirstOrDefault(p => (p.Patente == patente & p.AduanaDespacho == aduana & p.Pedimento == pedimento2));
if (pedimento == null)
return "";
else
return Convert.ToString(pedimento.Id);
}
}
I am trying to build a search predicate in code that compares two fields in Sitecore and I am getting a strange error message. Basically I have two date fields on each content item - FirstPublishDate (the date that the content item was first published) and LastPublishDate (the last date that the content item was published). I would like to find all content items where the LastPublishDate falls within a certain date range AND where the LastPublishDate does not equal the FirstPublishDate. Using Linq here is my method for generating the predicate...
protected Expression<Func<T, Boolean>> getDateFacetPredicate<T>() where T : MySearchResultItem
{
var predicate = PredicateBuilder.True<T>();
foreach (var facet in myFacetCategories)
{
var dateTo = System.DateTime.Now;
var dateFrom = dateTo.AddDays(facet.Value*-1);
predicate = predicate.And(i => i.LastPublishDate.Between(dateFrom, dateTo, Inclusion.Both)).And(j => j.LastPublishDate != j.FirstPublishDate);
}
return predicate;
}
Then I use this predicate in my general site search code to perform the search as follows: the above predicate gets passed in to this method as the "additionalWhere" parameter.
public static SearchResults<T> GeneralSearch<T>(string searchText, ISearchIndex index, int currentPage = 0, int pageSize = 20, string language = "", IEnumerable<string> additionalFields = null,
Expression<Func<T, Boolean>> additionalWhere = null, Expression<Func<T, Boolean>> additionalFilter = null, IEnumerable<string> facets = null,
Expression<Func<T, Boolean>> facetFilter = null, string sortField = null, SortDirection sortDirection = SortDirection.Ascending) where T : SearchResultItem {
using (var context = index.CreateSearchContext()) {
var query = context.GetQueryable<T>();
if (!string.IsNullOrWhiteSpace(searchText)) {
var keywordPred = PredicateBuilder.True<T>();
// take into account escaping of special characters and working around Sitecore limitation with Contains and Equals methods
var isSpecialMatch = Regex.IsMatch(searchText, "[" + specialSOLRChars + "]");
if (isSpecialMatch) {
var wildcardText = string.Format("\"*{0}*\"", Regex.Replace(searchText, "([" + specialSOLRChars + "])", #"\$1"));
wildcardText = wildcardText.Replace(" ", "*");
keywordPred = keywordPred.Or(i => i.Content.MatchWildcard(wildcardText)).Or(i => i.Name.MatchWildcard(wildcardText));
}
else {
keywordPred = keywordPred.Or(i => i.Content.Contains(searchText)).Or(i => i.Name.Contains(searchText));
}
if (additionalFields != null && additionalFields.Any()) {
keywordPred = additionalFields.Aggregate(keywordPred, (current, field) => current.Or(i => i[field].Equals(searchText)));
}
//query = query.Where(i => (i.Content.Contains(searchText) || i.Name.Contains(searchText))); // more explicit call to check the content or item name for our term
query = query.Where(keywordPred);
}
if (language == string.Empty) {
language = Sitecore.Context.Language.ToString();
}
if (language != null) {
query = query.Filter(i => i.Language.Equals(language));
}
query = query.Page(currentPage, pageSize);
if (additionalWhere != null) {
query = query.Where(additionalWhere);
}
if (additionalFilter != null) {
query = query.Filter(additionalFilter);
}
query = query.ApplySecurityFilter();
FacetResults resultFacets = null;
if (facets != null && facets.Any()) {
resultFacets = facets.Aggregate(query, (current, fname) => current.FacetOn(i => i[fname])).GetFacets();
}
// calling this before applying facetFilter should allow us to get a total facet set
// instead of just those related to the current result set
// var resultFacets = query.GetFacets();
// apply after getting facets for more complete facet list
if (facetFilter != null) {
query = query.Where(facetFilter);
}
if (sortField != null)
{
if (sortDirection == SortDirection.Ascending)
{
query = query.OrderBy(x => x[sortField]);
}
else
{
query = query.OrderByDescending(x => x[sortField]);
}
}
var results = query.GetResults(); // this enumerates the actual results
return new SearchResults<T>(results.Hits, results.TotalSearchResults, resultFacets);
}
}
When I try this I get the following error message:
Server Error in '/' Application.
No constant node in query node of type: 'Sitecore.ContentSearch.Linq.Nodes.EqualNode'. Left: 'Sitecore.ContentSearch.Linq.Nodes.FieldNode'. Right: 'Sitecore.ContentSearch.Linq.Nodes.FieldNode'.

Exception Details: System.NotSupportedException: No constant node in query node of type: 'Sitecore.ContentSearch.Linq.Nodes.EqualNode'. Left: 'Sitecore.ContentSearch.Linq.Nodes.FieldNode'. Right: 'Sitecore.ContentSearch.Linq.Nodes.FieldNode'.
Source Error:
Line 548: FacetResults resultFacets = null;

Line 551: }
Line 552: // calling this before applying facetFilter should allow us to get a total facet set
From what I can understand about the error message it seems to not like that I am trying to compare two different fields to each other instead of comparing a field to a constant. The other odd thing is that the error seems to be pointing to a line of code that has to do with aggregating facets. I did a Google search and came up with absolutely nothing relating to this error. Any ideas?
Thanks,
Corey
I think what you are trying is not possible, and if you look at this that might indeed be the case. A solution that is given there is to put your logic in the index: create a ComputedField that checks your dates and puts a value in the index that you can search on (can be a simple boolean).
You will need to split your logic though - the query on the date range can still be done in the predicate (as it is relative to the current date) but the comparison of first and last should be done on index time instead of on query time.
i have a single textbox named Keywords.
User can enter multiple strings for search.
How this is possible in mvc3?
I am using nhibernate as ORM.
Can i create criteria for this?
Edited Scenario
I have partial view to search job based on following values:
Keywords(multiple strings), Industry(cascading dropdown with functional area )//working well ,FunctionalArea//working well
Loaction(multiple locations), Experience//working well
In Controller i am retrieving these values from form collection.
What datatype should i use for keywords and location (string or string[] )?
public ActionResult SearchResult(FormCollection formCollection)
{
IList<Jobs> JobsSearchResultList = new List<Jobs>();
//string[] keywords = null;
string location = null;
int? industry = 0;
int? functionaArea = 0;
int? experience = 0;
string keywords = null;
if (formCollection["txtKeyword"] != "")
{
keywords = formCollection["txtKeyword"];
}
//if (formCollection["txtKeyword"] != "")
//{
// keywordAry = formCollection["txtKeyword"].Split(' ');
// foreach (string keyword in keywordAry)
// {
// string value = keyword;
// }
//}
......retrieving other values from formcollection
....
//Now passing these values to Service method where i have criteria for job search
JobsSearchResultList = oEasyJobsService.GetJobsOnSearchExists(keywords,industry,functionaArea,location,experience);
return View(JobsSearchResultList);
}
In Services i have done like:
public IList<EASYJobs> GetJobsOnSearchExists(string keywords, int? industryId, int? functionalAreaId, string location, int? experience)
{
IList<JobLocation> locationlist = new List<JobLocation>();
IList<Jobs> JobsList = null;
var disjunction = Expression.Disjunction();
ICriteria query = session.CreateCriteria(typeof(Jobs), "EJobs");
if (keywords != null)
{
foreach (string keyword in keywords)
{
string pattern = String.Format("%{0}%", keyword);
disjunction
.Add(Restrictions.InsensitiveLike("Jobs.keywords", pattern,MatchMode.Anywhere))
.Add(Restrictions.InsensitiveLike("YJobs.PostTitle",pattern,MatchMode.Anywhere));
}
query.Add(disjunction)
.Add(Expression.Eq("EASYJobs.Industry.IndustryId", industryId))
.Add(Expression.Eq("Jobs.FunctionalArea.FunctionalAreaId", functionalAreaId))
.Add(Expression.Eq("Jobs.RequiredExperience", experience)));
}
else
{..
}
JobsList = criteria.List<Jobs>();
}
Problems i am facing are:
In controller if i use string[],then Split(',') does not split the string with specified separator.It passes string as it is to Service.
2.In services i am trying to replace string with %{0}% ,strings with spaces are replaced/concat() here with given delimeter.
But the problem here is It always return the whole job list means not giving the required output.
Pleas help ...
As long as you have a delimiter you can break the input into pieces on you should be able to create an or expression with the parts. You can use a disjunction to combine an arbitrary number of criteria using OR's.
var criteria = session.CreateCriteria<TestObject>();
Junction disjunction = Restrictions.Disjunction();
var input = "key words";
foreach (var keyword in input.Split(" "))
{
ICriterion criterion = Restrictions.Eq("PropertyName", keyword);
disjunction.Add(criterion);
}
criteria.Add(disjunction);
Multiple keywords with special characters or extra spaces are replaced with single space with Regex expressions.
And then keywords are separated with Split("").
Its working as required....
if (!string.IsNullOrEmpty(keywords))
{
keywords = keywords.Trim();
keywords = System.Text.RegularExpressions.Regex.Replace(keywords, #"[^0-9a-zA-Z\._\s]", " ");
keywords = System.Text.RegularExpressions.Regex.Replace(keywords, #"[\s]+", " ");
if (keywords.IndexOf(" ") > 0)
{
string[] arr = keywords.Split(" ".ToCharArray());
for (int i = 0; i < arr.Length; i++)
{
if (!string.IsNullOrEmpty(arr[i]))
{
criteria.Add(Restrictions.Disjunction()
.Add(Expression.Like("EASYJobs.keywords", arr[i], MatchMode.Anywhere)));
}
}
}
else
{
criteria.Add(Restrictions.Disjunction()
.Add(Expression.Like("EASYJobs.keywords", keywords, MatchMode.Anywhere)));
}
}
While looking though some code of the project I'm working on, I've come across a pretty hefty method which does
the following:
public string DataField(int id, string fieldName)
{
var data = _dataRepository.Find(id);
if (data != null)
{
if (data.A == null)
{
data.A = fieldName;
_dataRepository.InsertOrUpdate(data);
return "A";
}
if (data.B == null)
{
data.B = fieldName;
_dataRepository.InsertOrUpdate(data);
return "B";
}
// keep going data.C through data.Z doing the exact same code
}
}
Obviously having 26 if statements just to determine if a property is null and then to update that property and do a database call is
probably very naive in implementation. What would be a better way of doing this unit of work?
Thankfully C# is able to inspect and assign class members dynamically, so one option would be to create a map list and iterate over that.
public string DataField(int id, string fieldName)
{
var data = _dataRepository.Find(id);
List<string> props = new List<string>();
props.Add("A");
props.Add("B");
props.Add("C");
if (data != null)
{
Type t = typeof(data).GetType();
foreach (String entry in props) {
PropertyInfo pi = t.GetProperty(entry);
if (pi.GetValue(data) == null) {
pi.SetValue(data, fieldName);
_dataRepository.InsertOrUpdate(data);
return entry;
}
}
}
}
You could just loop through all the character from 'A' to 'Z'. It gets difficult because you want to access an attribute of your 'data' object with the corresponding name, but that should (as far as I know) be possible through the C# reflection functionality.
While you get rid of the consecutive if-statements this still won't make your code nice :P
there is a fancy linq solution for your problem using reflection:
but as it was said before: your datastructure is not very well thought through
public String DataField(int id, string fieldName)
{
var data = new { Z = "test", B="asd"};
Type p = data.GetType();
var value = (from System.Reflection.PropertyInfo fi
in p.GetProperties().OrderBy((fi) => fi.Name)
where fi.Name.Length == 1 && fi.GetValue(data, null) != null
select fi.Name).FirstOrDefault();
return value;
}
ta taaaaaaaaa
like that you get the property but the update is not yet done.
var data = _dataRepository.Find(id);
If possible, you should use another DataType without those 26 properties. That new DataType should have 1 property and the Find method should return an instance of that new DataType; then, you could get rid of the 26 if in a more natural way.
To return "A", "B" ... "Z", you could use this:
return (char)65; //In this example this si an "A"
And work with some transformation from data.Value to a number between 65 and 90 (A to Z).
Since you always set the lowest alphabet field first and return, you can use an additional field in your class that tracks the first available field. For example, this can be an integer lowest_alphabet_unset and you'd update it whenever you set data.{X}:
Init:
lowest_alphabet_unset = 0;
In DataField:
lowest_alphabet_unset ++;
switch (lowest_alphabet_unset) {
case 1:
/* A is free */
/* do something */
return 'A';
[...]
case 7:
/* A through F taken */
data.G = fieldName;
_dataRepository.InsertOrUpdate(data);
return 'G';
[...]
}
N.B. -- do not use, if data is object rather that structure.
what comes to my mind is that, if A-Z are all same type, then you could theoretically access memory directly to check for non null values.
start = &data;
for (i = 0; i < 26; i++){
if ((typeof_elem) *(start + sizeof(elem)*i) != null){
*(start + sizeof(elem)*i) = fieldName;
return (char) (65 + i);
}
}
not tested but to give an idea ;)
I'm using Linq to return data from an XML file to a DataTable and that works. But now I'm trying to modify the code to loop through the DataTable. I created a custom class to model the data and have a List in my model. When I loop through the DataTable to display records it displays System.Collections.Generic.List`1[System.String] instead of the actual data. I'm not sure what to search to find the answer.
Snippet:
foreach (DataRow row in tbl.Rows)
{
myList = row["myList"] + ", " + myList;
}
The myList column is the List. I hope this makes sense.
Edited:
public static DataTable LINQToDataTable<T>(IEnumerable<T> varlist)
{
DataTable dtReturn = new DataTable();
// column names
PropertyInfo[] oProps = null;
if (varlist == null) return dtReturn;
foreach (T rec in varlist)
{
// Use reflection to get property names, to create table, Only first time, others will follow
if (oProps == null)
{
oProps = ((Type)rec.GetType()).GetProperties();
foreach (PropertyInfo pi in oProps)
{
Type colType = pi.PropertyType;
if ((colType.IsGenericType) && (colType.GetGenericTypeDefinition() == typeof(Nullable<>)))
{
colType = colType.GetGenericArguments()[0];
}
dtReturn.Columns.Add(new DataColumn(pi.Name, colType));
}
}
DataRow dr = dtReturn.NewRow();
foreach (PropertyInfo pi in oProps)
{
dr[pi.Name] = pi.GetValue(rec, null) == null ?DBNull.Value :pi.GetValue
(rec,null);
}
dtReturn.Rows.Add(dr);
}
return dtReturn;
}
hobbiesList = (List<string>)row["hobbies"];
foreach (var item in hobbiesList)
{
hobbies.Add(item.ToString());
}
hobby = string.Join(", ", hobbies.ToArray());
hobbies.Clear();
I had to do the above to get it to work. I then add hobby to my output array.
