Dynamic SQL query Multiple rows based on table names linked in another table

P: 1
I have a sql 2008 R2 problem that I’ve tried to accomplishing using dynamic sql but, no luck yet.
Expand|Select|Wrap|Line Numbers
  1. Create Table Events (
  2. PKID    int  Not Null,
  3. TimeStamp Datetime,
  4. EventID        int,
  5. Eventdata     int)
  7. Create Table Eventdatalookup(
  8. Event    int,
  9. DataLookupTableName         varchar(100))
  11. Create Table TypicalEventDesc1(
  12. EventData     int
  13. EventDataDesc        varchar(100)
  14. Create Table TypicalEventDesc2(
  15. EventData     int
  16. EventDataDesc        varchar(100)
Im wanting to create a stored procedure that will lookup the description of the event id and event data in table Events based on a table name in another table. I have found examples of dynamic sql that will return the Desc for one row but there will be many many rows returned in this query.

Events.EventID--- EventDataLookup.Event
The DataLookupTableName Contains the name of the table from which the Events.EventData can be tied to TypicalEventDesc1.EventDataDesc or tied to TypicalEventDesc2.EventDataDesc

Is what I’m wanting to do even possible?

It's possible. The real question is why is the event data split across multiple tables when they should be in one table?
