Conditional join in Mysql select statement -


Text after "

I have two tables tbl_studentapplicationdetails and tbl_studentqualification ... my second table I have student ID and qualification ID ... Now I want to join two tables to get the list of students with my qualifications ...

Note: Some students There can be two or three qualifications .... and my question is 

  select specific t1.dStudent_id, t1.dStuFirstname, t1.dStuLastName, t1.dgender, t1.dfatherName, t1 .dOcupation, t1.dAddress, t1 DContactNumber, t1 internally as tbl_studentapplicationdetails as t2.dmarks as SSLC, t3.dmarks as HSC, t4.dmarks on T3.dQualification = '2' as t3 left t3.dQualification = '1 Joining the 'tbl_studentqualification' joining the T2 tbl_studentqualification on tbl_studentqualification to join tbl_studentqualification as t4.dQualification = T4 as the '7'

and my Tbl_studentqualification is

Edit: I want to select all REC two eligibility students Orders for students having three qualifications ....

As of now, your joining less Understand because you are not joining the eligibility table with application details. Given that you want to separate the student ID, you will only get one line per student.

If I understand what you want, so if you one Student line qualification (1,2, 7) of each type, so you'd rather ( I hope it is correct) should try this way: 

  dStudent_id, dStuFirstname, dStuLastName, dGender, dFatherName, dOcupation, dAddress, dContactNumber, Q1. As Dimsiars SSLC, q2.d as Marcus HSC, q7.d brands leave as related Tielbi_stidentpplifikeshn as Diplomo LEFT JOIN tbl_studentqualification q1 ON (q1.dStudent_id = dStudent_id and q1.dQQ = 1) two q2 at (q2.dStudent_id = join as dStudent_id) and q2.dQualification = '2') Left q7 on join tbl_studentqualification (q7.dStudent_id = dStudent_id and q7.dQualification = '7')

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
