Use stored procedure for search method - asp.net

Question

I started with ASP.Net Core 2.0, I'm trying to rewrite a method GetAll by search use stored procedure. Here is method search:
public async Task<List<DepartmentTypeDto>> SearchDepartmentType()
{
EnsureConnectionOpen();
using (var command = CreateCommand("CM_DEPT_GROUP_Search", CommandType.StoredProcedure))
{
using (var dataReader = await command.ExecuteReaderAsync())
{
List<DepartmentTypeDto> result = new List<DepartmentTypeDto>();
while (dataReader.Read())
{
DepartmentTypeDto departmentTypeDto = new DepartmentTypeDto
{
GROUP_ID = dataReader["GROUP_ID"].ToString(),
GROUP_CODE = dataReader["GROUP_CODE"].ToString(),
GROUP_NAME = dataReader["GROUP_NAME"].ToString(),
NOTES = dataReader["NOTES"].ToString(),
RECORD_STATUS = dataReader["RECORD_STATUS"].ToString(),
MAKER_ID = dataReader["MAKER_ID"].ToString(),
CREATE_DT = Convert.ToDateTime(dataReader["CREATE_DT"]),
AUTH_STATUS = dataReader["AUTH_STATUS"].ToString(),
CHECKER_ID = dataReader["CHECKER_ID"].ToString(),
APPROVE_DT = Convert.ToDateTime(dataReader["APPROVE_DT"]),
AUTH_STATUS_NAME = dataReader["AUTH_STATUS_NAME"].ToString(),
RECORD_STATUS_NAME = dataReader["RECORD_STATUS_NAME"].ToString()
};
}
return result;
}
}
}
Here is the service:
public async Task<PagedResultDto<GetDepartmentTypeForView>> GetAll(GetAllDepartmentTypesInput input)
{
var filteredDepartmentTypes = _departmentTypeRepository.SearchDepartmentType();
var query = (from o in filteredDepartmentTypes
select new GetDepartmentTypeForView() { DepartmentType = ObjectMapper.Map<DepartmentTypeDto>(o) });
var totalCount = await query.CountAsync();
var departmentTypes = await query
.OrderBy(input.Sorting ?? "departmentType.id asc")
.PageBy(input)
.ToListAsync();
return new PagedResultDto<GetDepartmentTypeForView>(totalCount, departmentTypes);
}
But I get an error:
Task<List<DepartmentTypeDto>> does not contain a definition for Select
Does anyone know what I should do? I work on Asp.Net Zero.

Answer 1

I changed my search method
public IQueryable<DepartmentTypeView> SearchDepartmentType(GetAllDepartmentTypesInput input, int top)
{
try
{
var GROUP_FILTER = input.Filter;
var GROUP_CODE = input.GROUP_CODEFilter;
var GROUP_NAME = input.GROUP_NAMEFilter;
var AUTH_STATUS = input.AUTH_STATUSFilter;
var result = Context.Query<DepartmentTypeView>().FromSql($"EXEC CM_DEPT_GROUP_Search #p_GROUP_FILTER = {GROUP_FILTER}, #p_GROUP_CODE={GROUP_CODE}, #p_GROUP_NAME={GROUP_NAME}, #p_AUTH_STATUS={AUTH_STATUS}, #p_TOP={top}");
return result;
}
catch
{
return null;
}
}
and in the service, I call that function
var filteredDepartmentTypes = _departmentTypeRepository.SearchDepartmentType(input,100);
I also create new class to keep the result and don't forget to map that class with DTO class
configuration.CreateMap<DepartmentTypeView, DepartmentTypeDto>();
It works for me.
