Re: [U2] select query..
Hi Sathya, Clearly, in basic, if you know the unique-key of a record, you don't need to select it to access its data. Do it like this : OPEN FILE.NAME TO F.FILE.NAME ELSE ... error ... KEYVALUE = READ V.RECORD FROM F.FILE.NAME, KEYVALUE THEN * OK RECORD EXIST ; V.RECORD IS LOADED WITH DATA END ELSE * KO RECORD DOESN'T EXIST ! V.RECORD IS NOT MODIFIED V.RECORD = '' END Do what you need with V.RECORD -- Now if the value you have is not the unique-key ; you need to execute a select. Do like this : OPEN FILE.NAME TO F.FILE.NAME ELSE ... error ... DATAVALUE =. .. EXECUTE 'SELECT FILE.NAME WITH FIELD.NAME = "':DATAVALUE:'"' RTNLIST LIST1 LOOP WHILE READNEXT KEYVALUE DO READ V.RECORD FROM F.FILE.NAME,KEYVALUE THEN * OK RECORD EXIST END ELSE * KO RECORD DOEN'T EXIST CONTINUE ;* GOTO NEXT READNEXT END Do what you need with V.RECORD REPEAT By extension, You can create index à "secondary-key" declaration like this : At TCL,do like this (with users logged out) >CREATE.INDEX FILE.NAME FIELD.NAME NO.NULLS >BUILD.INDEX FILE.NAME FIELD.NAME If exist, Universe "SELECT" use automatically the "index" system - I hope this help.

Re: [U2] select query..
That's what READLIST and WRITELIST are for. I've found writing the list as "MY.LIST000" to be relatively safe, when you read you would have to check for "MY.LIST000", then "MY.LIST001", etc. Sathya - as Mecki said, if you're using the @ID of the file you can do a straight read to check if it's there.

Hi Do you have wildcard characters like [] into KEYVALUE ? If not, why do you SELECT ; it's the key of file.name ; you can read directly ! Elsewhere, For performance, set a index on the @id Why do you want to use save-list/get-list ? You can work on LIST1 directly ! manu > -Message d'origine- > De : u2-users-boun...@listserver.u2ug.org [mailto:u2-users- > boun...@listserver.u2ug.org] De la part de Sathya > Envoyé : mercredi 15 mai 2013 11:45 > À : u2-users@listserver.u2ug.org > Objet : [U2] select query.. > > Hi Experts.. > > I have one issue here with fetching data from the file. > > EXECLINE = "SELECT FILE.NAME WITH @ID = \":KEYVALUE:"\" > DISPLAY EXECLINE > EXECUTE EXECLINE RTNLIST LIST1 > EXECUTE 'SAVE-LIST SOME.LIST' PASSLIST LIST1 > > LIST.NAME = "GET-LIST SOME.LIST" > sellist = '' > EXECUTE LIST.NAME RTNLIST sellist CAPTURING junk > > Here Im running a loop for a set of "KEYVALUE"s and for each run the SSELECT > statement is taking around 30 seconds.

[U2] select query..
Hi Experts.. I have one issue here with fetching data from the file. EXECLINE = "SELECT FILE.NAME WITH @ID = \":KEYVALUE:"\" DISPLAY EXECLINE EXECUTE EXECLINE RTNLIST LIST1 EXECUTE 'SAVE-LIST SOME.LIST' PASSLIST LIST1 LIST.NAME = "GET-LIST SOME.LIST" sellist = '' EXECUTE LIST.NAME RTNLIST sellist CAPTURING junk Here Im running a loop for a set of "KEYVALUE"s and for each run the SSELECT statement is taking around 30 seconds. When I want to run 1000 loops, ideally the run time will be much. Is there any easier way to do this with less time consumption.
