how to join table and retrieve necessary columns - mysql

Question

we are working on api creation using asp.net core web api and mysql as backend. i need to maintain this architecture and and also need to join table. i have tried many ways still stuck in middle.
public class CallLogs:AuditableEntity
{
public int CallTypeId { get; set; }
public virtual CallType CallType { get; set; }
public virtual ICollection<CallType> CallTypes { get; set; }
public int PatientId { get; set; }
public int AgentId { get; set; }
public string CallDuration { get; set; }
public DateTime Date { get; set; }
public int ServiceId { get; set; }
public string Message { get; set; }
//public virtual Patient Patient { get; set; }
//public virtual Service Service { get; set; }
}
this calllogs has many tables foreign key and i want to retrieve some columns from each table. so how should i retrieve? in this project we added mapper classes and response and request classes
public class CallType:AuditableEntity
{
public string Name { get; set; }
public virtual ICollection<CallLogs> CallLogs { get; set; }
}
and made service where i including the tables
private ISpecification<CallLogs> GetSpecification(Expression<Func<CallLogs, bool>>
expression = null, string sortField = "none", int sortOrder = -1)
{
if (expression == null)
expression = v => v.IsDeleted != true;
Infrastructure.Specifications.BaseSpecification<CallLogs> specification =
new
Infrastructure.Specifications.BaseSpecification<CallLogs>(expression);
//specification.IncludeExp = p => p.Include(x => x.Patient);
specification.IncludeExp = p => p.Include(x => x.CallType);
// specification.IncludeExp = p => p.Include(x => x.Service);
if (sortField != "none" && !string.IsNullOrEmpty(sortField))
specification.OrderByDescending = p => p.GetSortOrder(sortField,
sortOrder);
else
specification.OrderByDescending = p => p.OrderByDescending(p =>
p.IsActive)
.ThenByDescending(p => p.CreatedDate)
.ThenByDescending(p => p.Id);
specification.IsPagingEnabled = true;
specification.Skip = (pageNo - 1) * pageSize;
specification.Take = pageSize;
return specification;
}
and we are calling this function in the getall api
public async Task<EntityResponseModel> GetAllAsync(int pageNo = 1, int pageSize = 10)
{
var callLogsResponse = new List<CallLogsResponse>();
this.pageNo = pageNo;
this.pageSize = pageSize;
var callLogs = (await repository.FindAsync(GetSpecification())).ToList();
// .Select(s => new
// {
// Name = s.CallType.Name,
// PateintId = s.PatientId,
// AgentId = s.AgentId,
// CallDuration = s.CallDuration,
// Date = s.Date,
// ServiceId = s.ServiceId,
// Message = s.Message,
// Id = s.Id,
// IsActive = s.IsActive
// }).ToList() ;
int count = await repository.CountAsync(v => !v.IsDeleted);
var _pages = Math.Round(count / (double)pageSize,
MidpointRounding.ToPositiveInfinity);
var statusCode = 200;
callLogsResponse = _mapper.Map<List<CallLogs>, List<CallLogsResponse>>
(callLogs);
return new EntityResponseModel
{
APIResponse =
APIResponseHelper.Getinstance().ConvertToAPIResponse(callLogsResponse,
string.Empty,statusCode, Convert.ToInt32(_pages),
Convert.ToInt32(count)),
Entity = callLogs,
EntityResponse = callLogsResponse
};
}
how do i join table and column what i need?
