Can anyone tell me ,How to insert comma values in a single column in sql server and Join them using split by comma function.

What I have tried:

ID Name Dept   Sal      Techids
 1  Abc  Mech  20000    1,2,3

Techid  Techname
   1       Abc
   2       def
   3       ghi

Don't. It's a PITA to use, and though it's simple to insert the values to start with, it rapidly descends into nastiness.
Instead, have a "linking" table:
ID Name Dept   Sal      
 1  Abc  Mech  20000    

Techid  Techname
   1       Abc
   2       def
   3       ghi

ID   DeptId   TechId
1      1        1
2      1        2
3      1        3
You then use a JOIN to combine information when you want to retrieve it.
SELECT d.*, t.TechName FROM Depts d
JOIN DeptTech dt ON d.ID = dt.DeptId
JOIN Techs t ON d.TechID = t.ID
That way, adding and removing techs is a trivial job: just delete the linking row.

Then learn to understand it - storing data in CSV in SQL is a bad idea - the code you need to use it is a true PITA. Think about it: how do you remove a TechId from a comma separated list? You can do it, but it's truly a pain. Setting up an extra table to link the the existing tables together is really far, far easier than messing with CSV values at all.
Splitting it out to rows is complex enough:
anything else becomes a total nightmare!
