Generate proper report when data is not in database [Telerik] - sql

Question

I'm generating telerik report for
"Number of students by level of education, field and sex"
Here the SQL query that I'm using to create this report
SELECT
[tbl_hec_ISCED].[ISCED_ID],
[tbl_hec_ISCED].[ISCED_Level],
[tbl_hec_Programme].[ISCED_ID] AS 'tbl_hec_ProgrammeISCED_ID',
[tbl_hec_Programme].[Programme_ID],
[tbl_hec_Programme].[Specialisation_ID_Number],
[tbl_hec_specialisation].[Rank_ID_Number],
[tbl_hec_specialisation].[Rank_Title],
[tbl_HEI_student].[Programme_ID] AS 'tbl_HEI_studentProgramme_ID',
[tbl_HEI_student].[Gender]
FROM ((([tbl_HEI_student]
FULL OUTER JOIN [tbl_hec_Programme]
ON [tbl_HEI_student].[Programme_ID] = [tbl_hec_Programme].[Programme_ID])
FULL OUTER JOIN [tbl_hec_specialisation]
ON [tbl_hec_Programme].[Specialisation_ID_Number] = [tbl_hec_specialisation].[Rank_ID_Number])
FULL OUTER JOIN [tbl_hec_ISCED]
ON [tbl_hec_Programme].[ISCED_ID] = [tbl_hec_ISCED].[ISCED_ID])
WHERE ([tbl_HEI_student].[Gender]='Male' or [tbl_HEI_student].[Gender]='Female') and ([tbl_hec_ISCED].[ISCED_Level]='5' or [tbl_hec_ISCED].[ISCED_Level]='6'or [tbl_hec_ISCED].[ISCED_Level]='7'or [tbl_hec_ISCED].[ISCED_Level]='8')
I'm getting null report since some values are not in database. I attached picture of it ,
HERE that view
I want generate report when there is no data in database. like below which means zero values for null rows.
HERE the expected report output
How can I overcome this challenge

Answer 1

My suggestion is to use document merging functionality using a template with all the report layout already set up as well as value placeholders (fields) that will be replaced by calculated values.
I'm using Aspose.Words library in my projects, but I'm sure there are others out there maybe even Telerik Reporting. This is very simple functionality so any reporting tool that can do complex stuff must be able to do this as well.
Here's some example code for Aspose. Other libraries will have different implementation.
using Aspose.Words;
void GenerateDocument(string templateFilePath, Dictionary<string, object> fieldNamesAndValues)
{
// This is our document object
Document output = null;
// Obtain the template file
if (File.Exists(templateFilePath))
{
// If the template file is successfully located, use this template
output = new Document(templateFilePath);
}
// Merge the provided values into the appropriate fields of the template
output.MailMerge.Execute(fieldNamesAndValues.Keys.ToArray(), fieldNamesAndValues.Values.ToArray());
// Save the document into a stream as PDF
MemoryStream stream = new MemoryStream();
doc.Save(stream, SaveFormat.Pdf);
// You can then do whatever with the stream:
// save it or push it to the browser for download
}
Using your expected result as an example, let's assume these are the names of your placeholders (fields) for the first row:
MALE_EDUCATION_ISCED5, MALE_EDUCATION_ISCED6, MALE_EDUCATION_ISCED7
You can then generate your report like so:
Dictionary<string, object> fieldsAndValues = new Dictionary<string, object>();
fieldsAndValues.Add("MALE_EDUCATION_ISCED5", calculatedValue1);
fieldsAndValues.Add("MALE_EDUCATION_ISCED6", calculatedValue2);
fieldsAndValues.Add("MALE_EDUCATION_ISCED7", calculatedValue3);
// and so on for other fields
GenerateDocument("~/Templates/Report.docx", fieldsAndValues);
