Question

Our chief database programmer is out this week on vacation and I’m stuck.

I have a view that’s getting created that includes the following sub-query:

select cast(cast(getdate() + i as date) as datetime) DATEVALUE 
from NumbersTable(1,100,1)

I have no idea what this does, and when I try to run it inside of Squirrel, I get:

Error: Procedure or function NumbersTable has too many arguments specified.
SQLState:  37000
ErrorCode: 8144

Here are the function creates for NumbersTable:

    CREATE FUNCTION NumbersTable (
  @fromNumber int,
  @toNumber int,
  @byStep int
) RETURNS TABLE
RETURN (

WITH CTE_NumbersTable AS (
  SELECT @fromNumber AS i
  UNION ALL
  SELECT i + @byStep
  FROM CTE_NumbersTable
  WHERE
  (i + @byStep) <= @toNumber
)
SELECT * 
FROM CTE_NumbersTable
)
;

and

CREATE FUNCTION NumbersTable (
  @fromNumber int,
  @toNumber int
) RETURNS TABLE
RETURN (
WITH T_0_THRU_15 AS (
SELECT 0 j UNION ALL
SELECT 1 UNION ALL
SELECT 2 UNION ALL
SELECT 3 UNION ALL
SELECT 4 UNION ALL
SELECT 5 UNION ALL
SELECT 6 UNION ALL
SELECT 7 UNION ALL
SELECT 8 UNION ALL
SELECT 9 UNION ALL
SELECT 10 UNION ALL
SELECT 11 UNION ALL
SELECT 12 UNION ALL
SELECT 13 UNION ALL
SELECT 14 UNION ALL
SELECT 15 
)
SELECT T1.j + (T2.j*16) + (T3.j*256) + @fromNumber i
FROM   T_0_THRU_15 T1, T_0_THRU_15 T2, T_0_THRU_15 T3
WHERE T1.j + (T2.j*16) + (T3.j*256) + @fromNumber <= @toNumber
)
;

I am running this against Microsoft SQL Server 2008 R2. The strange thing is that I believe I have run this code against this database before and it worked and I simply don’t know what to do now.

Answer 1

NumbersTable is probably a table valued function.

Try this:

select cast(cast(getdate() + i as date) as datetime) DATEVALUE  
from dbo.NumbersTable(1,100,1) 

It probably means “return the values from 1 to 100 in increments of 1”.
