Hi,

I'm using Linq-To-Sql.

Given the following code:

casefile.cs

publicpartialclasscasefile
{
     publicstaticint getCaseId(string asCaseNumber)
  {
           int aiCaseId = -1;

     using (CMSDataContext dc =new CMSDataContext())
     {
                 aiCaseId = (from cin dc.casefile
                    where c.case_nbr == asCaseNumber
                    select c.case_id).FirstOrDefault();

        if (aiCaseId ==null || aiCaseId < 1)       
                {
                       thrownewException(String.Concat("Case Number ", asCaseNumber, " not found."));
        }
          }

  return aiCaseId;
}
}

WebFormCMSCopyCommentEvent.aspx.cs

publicpartialclassWebFormCMSCopyCommentEvent : System.Web.UI.Page
{

      protectedvoid ButtonShowRecords_Click(object sender,EventArgs e)         
            {
                    //validate CaseIds
          int aiCaseId1 =casefile.getCaseId(TextBoxCaseNo1.Text); errors here => CS0117: casefile does not get a definition for 'getCaseId'

      }
}

}

Hi,

I have one table with large data around 1mio rows but if i have a large data why taking so long for next inserting data?
Is possible increase for fast?

Regards

I have two entities in the model, Audit and Audit_Measure. They are in a many to many relationship which is reflected in the model.
i.e. Audit has a virtual ICollection Audit_Measures, and Audit_Measure has a corresponding virtual ICollectionAudits.

I am trying to return a list of Audit_Measures, for a particular Audit.

Assuming the usual try..catch..using etc, the code is:

audit_measures_in_audit = await db.Audit_Measures
                        .Where(am => am.Audits.Contains(audit))
                        .ToListAsync();

It's falling over on the 'Contains' clause with an exception:
"Unable to create a constant value of type 'CACS_GNS_Data.Models.Audit'. Only primitive types or enumeration types are supported in this context.."

I have since managed to get around it, but am not sure why I am getting the error.
Surely this is why the virtual collections exist in the model.

Thanks

Hello all,

imagine this scenario, i have a device when the user connect i call a web service and get some resutl

IEnumerable<someObject>

i insert all content into the database all works fine.

Now, we add in the back end some new object, modify, update, delete and so on ...

user make a log off, when user connect again i call again the web service and get the new IEnumerable<someObject>

I would like to know i can make a find the DIFFERENCE between these two objects ?

because i need to insert some news, and delete some old ...

I've try that, but that's work only if i have some new object IN the wsDatas

//a: get datas from db
                    var dbDatas = from db in xxx.SelectAll<someObject(true)
                                  select new { db.ProfileCode, db.ProductCode, db.CategoryCode, db.OptionCode };

//b: get data from web service
                    var wsDatas = from ws in datas
                                  select new { ws.ProfileCode, ws.ProductCode, ws.CategoryCode, ws.OptionCode };

                    // compare
                    var newDatas = wsDatas.Except(dbDatas);

of course, i can delete all datas and replace all but i would like to know how to find difference between two list of objects

thanks in advance

Hi

  I am executing sql script it is giving me error 'An unhandled exception of type System.Outofmemoryexecption' occurred in mscorlib.dll. File size is more than 10 G.B

I want to increase the session timing of my ASP.NET web App hosted in IIS 6.0. So, I changed the SessionState timing to 600 mins in web.config of the site. But it didn't work and my session times out like in an hour.(Session["myVariable"] == null)

<system.web><sessionState timeout="600"/></system.web>

Now I tried setting the Timeout value in IIS website where this application is hosted by going to website -> Properties -> Home Directory Tab -> Configuration button -> Options tab and changin it to 600 mins, still no luck. The question here says that this is for classic ASP Pages but not for ASP.NET web sites. which means that I am doing it wrong.

Then I checked the app pool under which this application runs (app Pool->Properties-->Performance tab). This says "Recycle Worker Process(in minutes)" as 10 mins. I read many questions on SO but none of them gives a clear cut answer on how to increase the session timeout on ASP.NET WebApp.

I want to know the difference between these three settings and when to use which and how do we increase the session timeout of my webApp.

I know I can use other session state methods like StateServer and SQL Server but It could be quite laborious for me to change the way each session variable is accessed. More over Session_End method doesn't fire in StateServer mode which Ia m using for some resource cleaning.

So, overall i am looking to extend the session time to 600 mins with INPROC session mode which is not working. Any pointers on that and help me understand the best option possible

Can anyone recommend some really good books or articles covering the .net entity framework and linq. The books or tutorials dont have two discuss these technologies together. I want to make sure that I could use the .net entity framework as a repository as someone suggested. Thanks !

I have the following class.

publicclassUser{publicintId{ get;set;}publicstringFirstName{ get;set;}publicstringLastName{ get;set;}publicbyte[]RowVersion{ get;set;}publicboolIsDeleted{ get;set;}}

How can I set default value for property IsDeleted using Fluent API. Method HasDefaultValue is not available. I have tried to set via constructor, the same result. In constructor I have tried false value, field still doesn't have default value. 

The solution presented below, also didn't succeed.

public bool IsDeleted { get; set; } = false;

Hello guys,

I want to make amendment to below function to accommodate filter-expression and  not sure how to achieve it. can someone help me with this?

  public static IQueryable<T> PagedResult<T, TResult>(IQueryable<T> query, int pageNum, int pageSize,
                Expression<Func<T, TResult>> orderByProperty, bool isAscendingOrder, string filterExpression, out int rowsCount)
        {
            //if (pageSize <= 0) pageSize = 20;

            //Total result count
            rowsCount = query.Count();

            //If page number should be > 0 else set to first page
            if (rowsCount <= pageSize || pageNum <= 0) pageNum = 1;

            //Calculate nunber of rows to skip on pagesize
            int excludedRows = (pageNum - 1) * pageSize;

            query = isAscendingOrder ? query.OrderBy(orderByProperty) : query.OrderByDescending(orderByProperty);

query= query.Where(????);

            //Skip the required rows for the current page and take the next records of pagesize count
            return query.Skip(excludedRows).Take(pageSize);
        }

Hello,

I want to build dynamic lambda expression like this: x=> x.ID.

From one of the posts i could so far build x => x.Id >= 3. Can someone help me toachieve x=> x.ID using code below:

var parameter = Expression.Parameter(typeof(Person), "x");
                var member = Expression.Property(parameter, "Id"); //x.Id
                var constant = Expression.Constant(3);
                var body = Expression.GreaterThanOrEqual(member, constant); //x.Id >= 3
                var finalExpression = Expression.Lambda<Func<Person, bool>>(body, param); x => x.Id >= 3

</div>

Hi,

I have a class that represents one of my tables (I used EntityFramework with Code-First):

    [Table("Logística$Sales Invoice Header")]
    public partial class Logística_Sales_Invoice_Header
    {
        [Column(TypeName = "timestamp")]
        [MaxLength(8)]
        [Timestamp]
        public byte[] timestamp { get; set; }

        [Key]
        [StringLength(20)]
        public string No_ { get; set; }

        [Column("Sell-to Customer No_")]
        [Required]
        [StringLength(20)]
        public string Sell_to_Customer_No_ { get; set; }

And when I am trying to pass a result of a query to an instance of this class, shows this error:

The data reader is incompatible with the specified 'FAMO.BaseItems.Database.urano.famNAV.Logística_Sales_Invoice_Header'. A member of the type, 'Sell_to_Customer_No_', does not have a corresponding column in the data reader with the same name.

This is my query:

SELECT a.* FROM [Logística$Sales Invoice Header] AS a INNER JOIN [Logística$Sales Invoice Line] AS b ON a.No_ = b.[Document No_] WHERE 1 = 1 AND b.Type = 2 AND a.[Bill-to Customer No_] = 'IC00029' AND b.No_ = 'XFMR2812B' AND b.[Cross-Reference No_] = '20M39' AND a.[Document Date] >= CONVERT(datetime, '02/01/2018', 103) AND a.[Document Date] <= CONVERT(datetime, '01/02/2018', 103)

Can someone help me?

    DbDataAdapter da = _dataFactory.CreateDataAdapter();
          
               DbParameter param1 = null;
              
                DataTable dt = new DataTable("USER1");
             
            try
            {
                conn.ConnectionString = _connectionString;
                conn.Open();
                string _sql1 = "SELECT * FROM USERGROUP WHERE CODE='ABC' ";
                da.SelectCommand = conn.CreateCommand();
                da.SelectCommand.CommandText = OracleHelper.FixCommandText(_sql1);
                da.SelectCommand.CommandType = CommandType.Text;

                OracleHelper.CreateParameter(ref da, ref param108, "@CODE", DbType.String, ParameterDirection.Input,_code);

                da.Fill(dt);

                if (dt._CODE = "ABC")
                {
                
                   
                  }

In above queries , the Values from usergroup is filling into dt. Now i want to check value of code inside the dt is equal to "ABC". Error is showing for  if (dt._CODE = "ABC")

Below is my case:
I have a dictionary of 1000 items as ProductDict<Upc1, Upc2> where Upc1 and Upc2 are strings which are different records in Product table. I am trying to copy properties from one object to another which are of same type. 

I don't want to do as below:
a. For loop for 1000 items
b. Linq select query to get product object for Upc1
c. Linq select query to Get product object for Upc2
d. Copy attributes from Upc2 to Upc1

Also the dictionary is one-to-one like object 'A' has to be copied to 'A1' and B to 'B1' and etc. Is there any better way to do it batches? I am using Linq sql queries.

i've  a stored procedure with not output parameters,  when i try running it, i get -1  as output, i've a delete statement inside sp, sp runs individually on sql server, but when i call from ef core it returns -1

, 

var parameters = new []{newSqlParameter("@returnVal", (object)param1),
newSqlParameter("@returnVal", (object)param2),
newSqlParameter("@returnVal", (object)param3),
    ..........};


var b = await  _stagingContext.Database.ExecuteSqlCommandAsync("exec proacName",parameters);//optionally i tried

var result =  _stagingContext.SaveChanges();

//b = -1 and c =0;

I'm using EFCore,
