Question

I am having trouble including an XML namespace in the following table-valued function. I need this namespace in order to perform an xpath join. The issue seems to be my use of the WITH method, but this syntax is required when I execute the query in straight SQL.

The exact error reads:

“Incorrect syntax near ‘default’. Expected ID or QUOTED_ID.”

Does anyone know the exact syntax for including an XML namespace in this T-SQL table-valued function body? Here is the T-SQL code:

USE [Context]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[GetStuff]()
RETURNS @X TABLE(
  DisplayName NVARCHAR(250) NULL,
  StandardCode NVARCHAR(250) NULL
)
--WITH RETURNS NULL ON NULL INPUT
AS      
BEGIN

DECLARE @MyTempTable  TABLE ( 
  DisplayName NVARCHAR(250) NULL,
  StandardCode NVARCHAR(250) NULL
);

;WITH XMLNAMESPACES (default 'http://www.mynamespace.org/someSchema')

INSERT INTO @MyTempTable (DisplayName, StandardCode)
    SELECT Distinct OI.DisplayName, OI.StandardCode
    FROM db..Actor B
    JOIN db..Part DP ON B.Id = DP.Id
    JOIN db..Intent OI ON OI.StandardCode = DP.XML.value('(/US/California/Orange/LA/Pizza)[1]','nvarchar(max)')
    JOIN db..Status PS ON B.Id = PS.Id
    WHERE PS.StandardCode in ('Happy','Employed')
    AND OI.Active = 1
    ORDER BY OI.DisplayName

  RETURN;

  END

I don’t think this solves the syntax error, but you are creating a second table variable for nothing. This:

ALTER FUNCTION [dbo].[GetStuff]()
RETURNS @X TABLE(
  DisplayName NVARCHAR(250) NULL,
  StandardCode NVARCHAR(250) NULL
)
--WITH RETURNS NULL ON NULL INPUT
AS      
BEGIN

DECLARE @MyTempTable  TABLE ( 
  DisplayName NVARCHAR(250) NULL,
  StandardCode NVARCHAR(250) NULL
);

;WITH ... INSERT @MyTempTable ...

Should be:

ALTER FUNCTION [dbo].[GetStuff]()
RETURNS @X TABLE(
  DisplayName NVARCHAR(250) NULL,
  StandardCode NVARCHAR(250) NULL
)
--WITH RETURNS NULL ON NULL INPUT
AS      
BEGIN

;WITH ... INSERT @X ...
