i have program fails intermittently in complex query.

the error reads:

system.data.sqlclient.sqlexception: cannot fetch row ole db provider "msdasql" linked server "linkedserver".

the query looks this:

    select replace([job-no],'m0','') keytaskid,                                                      dbo.sfget_uniquetaskid([client-code],replace([job-no], 'm0', ''), 0, [trade-code]) hmsuniquetaskid,                                                      [latest-priority] prioritycode,                                                      [keyproperty] keyproperty,                                                      replace([job-no],'m0','')  keyjob,                                                      [job-type] tasksubtype,                                                      convert(varchar(6),[maint-officer]) officer,                                                      left(forename + ' ' + surname, 50) officername,                                                      [job-no] + '  ' + left(rtrim(replace([text-line], ';', char(13))), 480) description,                                                      dbo.sfget_formatteddate([target-date],0) duedatetime,                                                      [current-stage-code] currentstagecode                                                 openquery(linkedserver, '                                               select distinct                                                      "rm-job"."job-no",                                                      "rm-job"."client-code",                                                      "rm-job"."latest-priority",                                                      "rm-job"."trade-code",                                                      "rm-job"."job-type",                                                      "rm-job"."target-date",                                                      "rm-job"."maint-officer",                                                      "rm-job"."text-line",                                                      "rm-job"."current-stage-code",                                                      "rm-job"."place-ref",                                                      "ih_officer".forename,                                                      "ih_officer".surname                                                 "pub"."rm-job"                                                 left outer join "pub"."ih_officer"                                                   on ("ih_officer"."officer-code" = "rm-job"."maint-officer")                                                 "rm-job"."job-type" = ''gass''                                                  , "rm-job"."job-status" = 06                                                  , "rm-job"."contractor" = ''nwh001'' ') ibstasks                                                inner join [svsextract].[dbo].property prop                                                   on ibstasks.[place-ref] = prop.usercode

i have been testing manually using sql server management studio. occassionally fails works ok.

i @ loss how can debug error cannot reproduce @ will.

any suggestions?

i'm not proficient in sqlclients , progress myself but: progress knowledgebase might give solution!

this entry instance describes similar error, if version mentioned might older 1 use? (always post version when asking openedge - there's lots of older installations out there , progress has evolved quite bit during last couple of years).

the knowledgebase best searched using google:

search instance: site:knowledgebase.progress.com msdasql , you'll 48 results.
