How to Get All Rows matched + Unmatched and Unmatched Rows Column Will be null - sql

Question

I am working on an university management system. This is my database diagram
Database Diagram
I am creating a search form using this query:
SELECT Distinct
TblStudentBioData.RegNo,
TblStudentBioData.First_NameUr + SPACE(1)+ TblStudentBioData.Middle_NameUr + SPACE(1) + TblStudentBioData.Last_NameUr AS Name,
TblStudentBioData.Father_NameUr,
Ay.AcademicYearName,
Smst.SemName,
TBLCOLLEGE.CollegeName,
CID.ClassName,
TblImages.Images,
TblStudentBioData.Student_ID,
TblImages.ImageId,
Ay.AcademicYearId,
Smst.SemesterId,
TblClassSchedule.ClassSchId
FROM
TblStudentBioData
LEFT JOIN
TblStudentDetail ON (TblStudentBioData.Student_ID = TblStudentDetail.Student_ID)
OR (TblStudentBioData.Student_ID != TblStudentDetail.Student_ID)
INNER JOIN
TBLCFGSEX AS sex ON TblStudentBioData.CfgSexId = sex.CfgSexId
INNER JOIN
TBLMARITALSTATUS ON TblStudentBioData.MaritalStatusId = TBLMARITALSTATUS.MaritalStatusId
INNER JOIN
TblStudentSubAss ON TblStudentDetail.StudentDetailID = TblStudentSubAss.StudentDetailID
INNER JOIN
TblSubAss ON TblSubAss.SubAssId = TblStudentSubAss.SubAssId
INNER JOIN
TblClassSchedule ON TblStudentDetail.ClassSchId = TblClassSchedule.ClassSchID
INNER JOIN
TableClass AS CID ON TblClassSchedule.ClassID = CID.ClassID
INNER JOIN
TblImages ON TblStudentBioData.ImageId = TblImages.ImageId
LEFT JOIN
TBLCOLLEGE ON CID.CollegeId = TBLCOLLEGE.CollegeID
INNER JOIN
TBLBLOODGROUP BG On TblStudentBioData.BloodID = BG.BloodId
INNER JOIN
tableSemAssigning SA On TblClassSchedule.SemAssId = Sa.SemAssId
INNER JOIN
TblAcademicYear AY On SA.AcademicYearId = AY.AcademicYearId
INNER JOIN
TableSemester Smst On Smst.SemesterId = Sa.SemesterId
and this query gives me the output like this
In the result the 5th row is not matching row.
My question: how to show null value in non matching row's columns which I mention in the image?

Answer 1

As far as I can tell it would be like this. Anything that relates directly to TblStudentBioData MIGHT be an an INNER JOIN (I cannot tell) but everything that relates to TblStudentDetail should be a left join.
Also be careful with any where clause that you don't override these left joins.
SELECT DISTINCT /* I hate distinct, there is probably a better way */
