SQL查詢語句--errno 934

xueyu_net

執行如下SQL：

select unique efa08,efa17,efaconf,pmc03 from
efa_file,outer pmc_file
where efa08=pmc01 and efa02='1Pe-A20043'
and efaconf='Y' and efa26<>'5'
and efa23='Y'
   934: 對於遠端系統的連接已不再正確.

若將SQL 更改一下就可以執行

select unique efa08,efa17,efaconf,pmc03 from
pmc_file,outer efa_file
where efa08=pmc01 and efa02='1Pe-A20043'
and efaconf='Y' and efa26<>'5'
and efa23='Y'

請指教！謝謝！
