I am using VS2008 C# and SQL2008 R2.

I would like to retrieve data from multiple columns and merge them, separating them by comma.

E.g. Data in my SQL Table Subject:

No. | CourseCode| subject |

1 | Cur001| English|
2 | Cur001| math|
3 | Cur001| Hindi|

Data I would like to display in my GridView GridView1:

No. | CourseCode| subject |

1 | Cur001 | English, math, Hindi|

how i write "SELECT" Command for this in sql2008 and C# code for GrideView

I do not understand where that "1" for "No." in the result is expected to come from - the Subject table has several different values.
By the way, your tags include C# - so why don't you do that in C# after getting the rows from the table to your program?

do not repost questions.
you already asked simillar question here ^[^]

as per basmeh Awad answer:-

select no,username,role1 +','+role2+','+role3 as ROLE from UserData

in case you need to combin a numeric data type with varchar datatype then you need to use this.

select no,username,cast(no as varchar)+','+role1 +','+role2+','+role3 as ROLE from UserData
