Get result of Database.SqlQuery - sql

I´ve a MVC 5 Project in VS 2013 with ODP.net Connection to an oracle database and entity framework 6.
I also have a view in my database which holds all information I need for my select call. I need to get all the information out of the database and display it on the webpage. I get the right number of elements in my list, but they are all empty.
I´ve read that my objects have to contain the correct names of the elements, but that isn´t working.
public class HomeController : Controller
{
public ActionResult Index()
{
using (var context = new DatabaseEntities())
{
var result =
context.Database.SqlQuery<MyEntity>(
"SELECT (case when HERKUNFT = 'AVZ' then ANLA_NR else LAG_NR end) \"LagerAnlage\", " +
"STO_NR \"Standort\", " +
"ART_NR \"Artikelnummer\", " +
"ART_KBEZ || '\n' || ART_BEZ1 || '\n' || ART_BEZ2 \"Artikelbezeichnung\", " +
"SN \"SN\", " +
"TO_CHAR(DTZUGANG, 'DD.MM.YYYY') \"Zugangsdatum\", " +
"TO_CHAR(DTABGANG, 'DD.MM.YYYY') \"Abgangsdatum\", " +
"WERT \"WertStk\", " +
"MENGE \"Stk\" " +
"FROM view_useravz " +
"WHERE user_cd = 'USERNAME' " +
"ORDER BY DTZUGANG");
var list = result.ToList();
}
return View();
}
}
class MyEntity
{
public string LagerAnlage;
public string Standort;
public string Artikelnummer;
public string Artikelbezeichnung;
public string SN;
public string Zugangsdatum;
public string Abgangsdatum;
public string WertStk;
public string Stk;
}

I don´t know why, but now I got an Error and was able to find a solution.
I chose the wrong types in my Class. When i set WertStk and Stk to int everything worked.

Select where string contains substring using Panache

I'm currently trying to implement the function "Load all X where X.name contains y" using a Ms SQL-Server and the Panache-Repositories.
I know the SQL-Query "SELECT * FROM X WHERE X.name LIKE '%0y%'" works, but I can't get it to work using the Panache-Query.
I've tried
#ApplicationScoped
public class XRepository implements PanacheRepository<X> {
public List<X> listWhereLike(String like) {
return list("name like ?1", "%" + like + "%");
}
public List<X> listWhereLike(String like) {
return list("name like %?1%", like);
}
public List<X> listWhereLike(String like) {
return list("contains(name, ?1)", like);
}
}
but none of them work.
They either throw an exception because of the unexpected character '%' or '(' or they simply return an empty list.
What am I missing?
This is the solution , you just need to put the pattern in a String before adding it to the query;
public List<X> listWhereLike(String like) {
String searchInput = "%" + like + "%";
return list("name like ?1", searchInput );
}

Created Entity using plugin has no valid Entity.Id Value

I have managed to execute the statement to create an entity successfully without any errors, but the id of the entity remains as default 00000000-0000-0000-0000-000000000000. In CRM, the created entity did not appear too.
I have not included all fields in the entity, and only inputting 1 field for testing.
Is it due to some mandatory fields not being filled, that is causing the above false positive that the entity is created?
Below is my code snippet:
Call CreateCase(row)
foreach (DataRow row in caseTable.Rows)
{
Entity caseEntity = helper.GetCasebyID((string)row[Excel.ID]);
if (caseEntity == null)
{
caseEntity = CreateCase(row);
}
}
CreateCase(row):
private Entity CreateCase(DataRow row)
{
Entity caseEntity = new Entity("new_case");
if (!(string.IsNullOrEmpty(row[Excel.sourcename].ToString().Trim())))
{
caseEntity.Attributes[Case.sourcename] = row[Excel.sourcename];
}
helper.GetOrganizationService().Create(caseEntity);
Logger.Info(caseEntity.LogicalName + " " + caseEntity.Id + " created. ");
//output: case 00000000-0000-0000-0000-000000000000 created.
}
Helper class:
public class Helper
{
private OrganizationServiceProxy _proxy;
private IOrganizationService _org;
public IOrganizationService GetOrganizationService()
{
if (_org == null)
{
var credential = new ClientCredentials();
credential.Windows.ClientCredential.Domain = ConfigurationManager.AppSettings["Domain"];
credential.Windows.ClientCredential.UserName = ConfigurationManager.AppSettings["Username"];
credential.Windows.ClientCredential.Password = Decrypt(ConfigurationManager.AppSettings["Password"]);
Uri organizationUri = new Uri(ConfigurationManager.AppSettings["OrganizationUri"]);
Uri homeRealmUri = null;
_proxy = new OrganizationServiceProxy(organizationUri, homeRealmUri, credential, null);
_proxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
_org = new OrganizationService(_proxy);
}
return _org;
}
}
You should not use the same object to check if record created or guid is available.
Below line in your code return Guid datatype and not subset of object.
helper.GetOrganizationService().Create(caseEntity);
Also when you create a record, Try to add atleast Primary name attribute value.
In your case it shall be new_name
So you should have your code as
Guid newlyCreatedCaseRecord = helper.GetOrganizationService().Create(caseEntity);
Logger.Info(caseEntity.LogicalName + " " + newlyCreatedCaseRecord + " created. ");
You could also fetch newly created Record from Database as Entity object.
Guid newlyCreatedCaseRecord = helper.GetOrganizationService().Create(caseEntity);
Entity newlyCaseEntity = helper.GetOrganizationService().Retrieve("new_case",newlyCreatedCaseRecord , new ColumnSet(true));
Logger.Info(newlyCaseEntity .LogicalName + " " + newlyCaseEntity.Id + " created. ");
Note: There can be Typo in code, try validating in Visual studio.

ArchUnit case insensitive name matching

I'm trying to setup tests with Arch Unit to test my naming conventions, following the official examples.
It seems ArchUnit's naming assertions are case sensitive, which is bothering me.
I want to test that no classes in the package domain.service contains the word service.
Given a class domain.service.FileSystemService:
This test passes:
#ArchTest
val domain_service_should_not_have_names_containing_service: ArchRule =
noClasses()
.that().resideInAPackage("..domain.service..")
.should().haveSimpleNameContaining("service")
This test fails:
#ArchTest
val domain_service_should_not_have_names_containing_service: ArchRule =
noClasses()
.that().resideInAPackage("..domain.service..")
.should().haveSimpleNameContaining("Service")
Am I missing something? Is there a way to make ArchUnit's comparisons case insensitive?
If you don't want to use haveNameMatching as proposed in the comments you can also create your own ArchConditions.
public static ArchCondition<JavaClass> containName(String namePart) {
return new NameContains(namePart);
}
private static class NameContains extends ArchCondition<JavaClass> {
private String namePart;
NameContains(String namePart) {
super("contain '" + namePart + "' in the name");
this.namePart = namePart;
}
#Override
public void check(JavaClass javaClass, ConditionEvents events) {
boolean containsName = javaClass.getSimpleName().toLowerCase().contains(namePart.toLowerCase());
String message;
if (containsName) {
message = createCheckMessage(javaClass, "contains '" + namePart + "' in the name");
} else {
message = createCheckMessage(javaClass, "does not contain '" + namePart + "' in the name");
}
events.add(new SimpleConditionEvent(javaClass, containsName, message));
}
}
// taken from com.tngtech.archunit.lang.conditions.ArchConditions
public static <T extends HasDescription & HasSourceCodeLocation> String createCheckMessage(T object,
String message) {
return object.getDescription() + " " + message + " in " + object.getSourceCodeLocation();
}
You can use it like this:
rules.add(noClasses().that().resideInAPackage("..domain.service..").should(containName("Service")));

Entity Framework select column values with group by

I want to get column values with group by. My tables are like this:
Table1
Id
Material
Length
Table2
Id
Name
Type
....
..
.
I can get plain sql query in a function.
public GetValues(tableName, columnName){
string sql = "select " + columnName + " from " + tableName + " group by " + columnName;
}
Is possible doing this via Entity Framework?
Create your table in EF with code first. A simple lambda group by looks like:
List<MyRecord> myTable = new List<UserQuery.MyRecord>();
var items = myTable.GroupBy(t => t.MyColumn);
public class MyRecord
{
public int MyRecordID { get; set; }
public string MyColumn { get; set;}
}
The EF equivalent is, using the entity you created would be:
MyEntities dbContext = new MyEntities()
using dbContext
{
var items = dbContext.MyTable // .. then a suitable lambda expression
}

Creating a multi-table SQL database in android

I'm trying to create a multi-table database for my android application. I'm following the suggestion given on this site http://androidforbeginners.blogspot.com/2010/01/creating-multiple-sqlite-database.html for doing it. I keep on getting the error below. The error seems to be cause by the onCreate of the databaes tables.
If you look at my onCreate in the the DBHelper class I have two commented out. This allows it to work no matter which one is left uncommeted.
There has to be a way to create a multi-table database because a single table in a database almost defeats the purpose of having a database.

I know I'm late,but i think it may help others reading this post.
I had the same problem and it's about spaces,be very careful when you're writing SQL queries about spaces.For example in the code above,you can notice that there's no space in the end :
KEY_OFFICERBADGE + "text not null"
So basically,you have declared a column with no type.
Hope it helped.
Put a Log statement in your open() method when you catch the SQLiteException to see if ticketDBHelper.getWritableDatabase() is failing and subsequently calling ticketDBHelper.getReadableDatabase(), which as the name implies, opens the database as read-only.
I have written a multi table app which works fine. Sounds like you may have a problem opening the existing db file for writing. I would suggest deleting that from your emulator/device, incrementing the version number and rerunning the app. My open method is pasted here.
public DbAdapter open() throws SQLException {
mDbHelper = new DatabaseHelper(mCtx);
mDb = mDbHelper.getWritableDatabase();
return this;
}

I have found a solution to the problem but not a direct answer on this site.

Why using a abstract class to create the databases the extending that class works I can't figure out for the life of me because it seems I'm doing the same thing in my one class up above. None the less it works as far as I've played around with it.
