sql server - Unpivot SQL statement -

- 

select    assylotno,    altlotname,    wfrnodisplay,    param.display,    param.value   emap_data unpivot  (value display in    (altlotnumber, wfrnumber, needspeedinfo, maptype, buildlist, type, productgrade,  assylotno) ) param

objective of query above have assylotno field included in display , value columns. fields exists in table emap_data, however, keep getting invalid column name field assylotno exists in emap_data.

emap_data table fields assylotno | altlotname | altlotnumber | wfrnodisplay | wfrnumber | needspeedinfo | maptype | buildlist     | type | productgrade  desired output follow: assylotno altlotname wfrnodisplay display        value ------------------------------------------------------------------ abc1231   abc123     01           altlotname     abc123 abc1231   abc123     01           wfrnumber      01 abc1231   abc123     01           needspeedinfo  y abc1231   abc123     01           maptype        12 abc1231   abc123     01           buildlist      1,2,3,4,5,6 abc1231   abc123     01           type           s abc1231   abc123     01           productgrade   c abc1231   abc123     01           assylotno      abc1231

ms sql server 2012 schema setup:

create table emap_data (   wfrnodisplay   varchar(20),   altlotname     varchar(20),     wfrnumber      varchar(20),   needspeedinfo  varchar(20),   maptype        varchar(20),   buildlist      varchar(20),   type           varchar(20),   productgrade   varchar(20),   assylotno      varchar(20) )   insert emap_data values ('01', 'abc123', '01','y','12','1,2,3,4,5,6','s','c','abc1231')

query 1:

select e.assylotno,        e.altlotname,        e.wfrnodisplay,        t.display,        t.value emap_data e   cross apply (values(altlotname,    'altlotname'),                      (wfrnumber,     'wfrnumber'),                       (needspeedinfo, 'needspeedinfo'),                      (maptype,       'maptype'),                       (buildlist,     'buildlist'),                       (type,          'type'),                       (productgrade,  'productgrade'),                       (assylotno,     'assylotno')               ) t(value, display)

results:
