Split function in SQL Server 2008

Question

I have Table1 with columns like this:

+--+------+
|ID|Name  |
+--+------+
|1 |MSSQL |
+--+------+
|2 |MySQl |
+--+------+
|3 |Oracle|
+--+------         


        

Answer 1

You are asking for a split function but you do not have to split your values to get the result you want.

This query builds the comma separated names list in a correlated subquery using the for xml trick to concatenate values. It uses like to figure out what values to use from Table1 for each row in Table2.

select (
       select ', '+T1.Name
       from Table1 as T1
       where ','+T2.Databasename+',' like '%,'+cast(T1.ID as varchar(10))+',%'
       for xml path(''), type
       ).value('substring(text()[1], 3)', 'varchar(max)') as Databasenames
from Table2 as T2
