Returns the specObjID of nearest photo object within @r arcmins of ra, dec |
ra, dec are in degrees, r is in arc minutes. This scalar function is used for matchups of external catalogs. It calls fGetNearestSpecObjAllEq(@ra,@dec,@r), and selects the specObjID (a bigint). This can be called by a single SELECT from an uploaded (ra,dec) table. An example: SELECT id, ra,dec, dbo.fGetNearestSpecObjIdAllEq(ra,dec,3.0) as specObjID FROM #upload WHERE dbo.fGetNearestSpecObjIdAllEq(ra,dec,3.0) IS NOT NULL
