I am using SQL Server 2008 R2.
I am stuck on the following situation and I am wondering how to achieve this.
table1:
ID   Data
1     Alpha
1     Beta
1     Gamma
2     Alpha
2     beta
3     Gamma
taking the data from table one and showing it like this
Table2:
ID   Data
1    Alpha, Beta, Gamma
2    Alpha, beta
3    Gamma
