I have to compare the IEnumerable data from UI and the IEnumerable data from SQL Server 2008 and have to insert/update the new elements from UI to DB and delete the elements from DB based on UI data.
I am having Distribution_X_ListType table in DB as:
DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
1 2 84528 NULL NULL
1 3 NULL 8051 NULL
1 5 NULL NULL 319
I am having an interface in a project as follows:
public interface IDistributionList : IEntity
{
string Name { get; set; }
bool ActiveFlag { get; set; }
...........................
...........................
IEnumerable<IDistributionListType> ListTypes { get; set; }
}
The another interface is:
public interface IDistributionListType
{
int? DistributionID { get; set; }
int ListTypeID { get; set; }
int EmployeeNumber { get; set; }
int DepartmentID { get; set; }
int LocationID { get; set; }
}
In another project I am having Save function as follows:
public int Save(IDistributionList distributionList)
{
SqlDataReader reader = null;
int rowsaffected = 0;
try
{
sqlcommand = new SqlCommand("spGetDistributionListTypeByID", con);
sqlcommand.CommandType = CommandType.StoredProcedure;
sqlcommand.Parameters.AddWithValue("@Distribution_ID", distributionList.ID);
reader = sqlcommand.ExecuteReader();
while (reader.Read())
{
????Value Should be stored in an IDistributionListType variable,say IDistributionListTypeFromDB
}
????IDistributionListType from function parameter(Lets say from UI) should be compared with the above IDistributionListTypeFromDB data.
????Insert/Delete should be done in DB by comparing the data.
}
}
Let the value of IDistributionListType from UI:
DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
1 2 84528 NULL NULL
1 5 NULL NULL 64
Let the value of IDistributionListType from DB:
DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
1 2 84528 NULL NULL
1 3 NULL 8051 NULL
1 5 NULL NULL 319
I need to update the DB with the data from UI. I am having two more SPs as :
spInsertUpdateDistributionListType - Insert/Update Distribution_X_ListType table based on DistributionID and listtypeID
spDeleteDistributionListType - Delete Distribution_X_ListType table based on DistributionID and listtypeID
I don't know how to code in ???? areas. Anybody please helpout. Thanks in advance.
