sql - R language sqldf package update table not working -


i exported data csv file r. using sqldf package udpate data. below query runs. can provide csv file dont know how attach files here :(

> sqldf("select * + ( +   + select disposition dummy_disposition, case disposition + when 'disposition'  'unknown' + when 'donate'  'eol' + when 'resale'  'eol' + when 'harvest'  'eol' + when 'intelspinoff'  'eol' + when 'scrap'  'eol' + when 'bufferfeedforward'   'active' + when 'fb'  'unknown' + when 'unknown'  'unkown' + when 'harvestresale'  'eol' + when 'returntosupplier'  'eol' + when 'icapresale'  'eol' + when 'nonemsmanaged'  'eol' + when 'buffereol'  'eol' + when 'resalescrap'  'eol' + when 'st'  'unknown' + when 'as'  'unknown' + else null end new_status, +   + *  floorstatus null ,  disposition not null +   +   + )  table1 +   new_status null")  [1] dummy_disposition new_status        ueid              date              enddate            [6] site              cfd               type              scheduleid        eventtype         [11] floorstatus       entitycode        ceid              process           supplier          [16] fa                mfgtype           disposition       comments          extra1            [21] extra2            extra3            <0 rows> (or 0-length row.names)

but when run below query doesnt run :( interesting because except update table part rest of query part of above query.

> sqldf("update set floorstatus = case disposition + when 'disposition'  'unknown' + when 'donate'  'eol' + when 'resale'  'eol' + when 'harvest'  'eol' + when 'intelspinoff'  'eol' + when 'scrap'  'eol' + when 'bufferfeedforward'   'active' + when 'fb'  'unknown' + when 'unknown'  'unknown' + when 'harvestresale'  'eol' + when 'returntosupplier'  'eol' + when 'icapresale'  'eol' + when 'nonemsmanaged'  'eol' + when 'buffereol'  'eol' + when 'resalescrap'  'eol' + when 'st'  'unknown' + when 'as'  'unknown' + else null end +    floorstatus null ,  disposition not null") error in sqliteexecstatement(con, statement, bind.data) :    rs-dbi driver: (error in statement: near "from": syntax error)

what wrong update table command? when run code in sql development studio runs fine...but prefer if code runs in r

update:

what changes need make below code????

declare @outputs table  ([day] datetime, floorstatus varchar,    quantity int)  declare @date datetime;   declare dates_cursor cursor select clndr_dt epsd.dbo.t_calendar               clndr_dt between '2008-01-01' , '2013-08-13'               order clndr_dt open dates_cursor fetch next dates_cursor @date  while @@fetch_status = 0     begin  insert @outputs        select @date [day], floorstatus, count(floorstatus) quantity graph_data        @date between [date] , enddate        group floorstatus  fetch next dates_cursor @date end close dates_cursor deallocate dates_cursor  select * @outputs

update not have from clause (see update syntax on sqlite site) , see sqldf faq #8 commonly made error of updating table in sqlite not returning table r.

Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners.
