FUNCTION fGetNearestObjIdEq

Returns the objId of nearest @table object within @r arcmins.

This scalar function is used for matchups of external catalogs.
It calls the fGetNearestObjEq(@ra,@dec,@r), and selects
the objId (a bigint). This can be called by a single SELECT from an uploaded
(ra,dec) table.

An example:
SELECT id, ra,dec, dbo.fGetNearestObjIdEq(ra,dec,3.0,1) AS objId FROM #upload WHERE dbo.fGetNearestObjIdEq(ra,dec,3.0,1) IS NOT NULL

Name Type Length inout pnum

@ra float 8 input 1

@dec float 8 input 2

@r float 8 input 3

@table tinyint 1 input 4

bigint 8 output 1

Name	Type	Length	inout	pnum
@ra	float	8	input	1
@dec	float	8	input	2
@r	float	8	input	3
@table	tinyint	1	input	4
	bigint	8	output	1
