  Hi All,

  I am having an experiment with passing tables as parameters into Functions. I have a table type set-up as follows

  CREATE TYPE MainProd AS TABLE

  (

  Year VARCHAR(4)

  ,ID 1 INT

  ,ID 2 INT

  ,hours INT

  )

  GO

  I have a function that uses the MainProd as a read only type.

  When I try to use the function I find I have to first declare a variable with this type, an example

  DECLARE @P MainProd

  Then call the function in SQL using the @P variable after inserting table values into @P

  SELECT * FROM [dbo].[MyBestProd] (@P) AS X

  Can I simply not write the SQL in the function parameter instead of having to use the @P parameter?

  I tried

  SELECT * FROM [dbo].[MyBestProd] ([my sql statement here]) AS X

  but it did not like it.

  Thanks

  Eliza

  I agree that passing in a subquery for the TYPEd table instead of having to predefine the table would be nice but as you have ascertained, SQL doesn't support it (at least not SQL 2008).

  My thought question: Have you ever been told that your query runs too fast?

  My advice:
  INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
  The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
