The following code gives me an invalid column name error for all the fields that I am trying to alter in the temporary table. It works fine if instead I write the table.

From other posts I have tried to change UPDATE #temp_polelbyregion with UPDATE y but I still have the same error messages

ALTER TABLE #temp_polelbyregion ALTER COLUMN REGION varchar(100)
ALTER TABLE #temp_polelbyregion ADD [Coordinate] float null
ALTER TABLE #temp_polelbyregion ADD [Street] float null
ALTER TABLE #temp_polelbyregion ADD [Block] float null
ALTER TABLE #temp_polelbyregion ADD [Postcode] float null
ALTER TABLE #temp_polelbyregion ADD [City] float null
ALTER TABLE #temp_polelbyregion ADD [County] float null
ALTER TABLE #temp_polelbyregion ADD [Cresta] float null
ALTER TABLE #temp_polelbyregion ADD [State] float null
ALTER TABLE #temp_polelbyregion ADD [Country] float null
ALTER TABLE #temp_polelbyregion ADD [None] float null
ALTER TABLE #temp_polelbyregion ADD [KnownCON] float null
ALTER TABLE #temp_polelbyregion ADD [KnownYB] float null
ALTER TABLE #temp_polelbyregion ADD [KnownHGT] float null
ALTER TABLE #temp_polelbyregion ADD [KnownOCC] float null

UPDATE #temp_polelbyregion

    ) x INNER JOIN #temp_polelbyregion y ON x.REGION = y.REGION AND x.ACCGRPID = y.ACCGRPID
