Hi,
i have two variables which are not passed in sql right now i want to get rid of that variables and pass them direct to sql how can i do that



v= DATE_STRING(CURRENT_JULIAN()-7, YYYYMMDD);

UserVar.DELTA_EndTime = STRING_concat(
     substr(v,1,4), '-',
     substr(v, 5,2), '-',
     substr(v,7,2), ' ',
     CURRENT_TIME())

UserVar.DELTA_StartTime is
select starttime from aaSTG_DELTA_TIMESTAMPS
where PROCESSKEY = 'Export Responses to MII'
with ur;

sql is

WHERE (((aa.new.GEO IN ('aa', 'bb')
                 AND (aaSTG_MATCHES.MATCH_TIMESTAMP >=
                         UserVar.DELTA_StartTime))
               AND (aaSTG_MATCHES.MATCH_TIMESTAMP < UserVar.DELTA_EndTime))
             AND (aaSTG_MATCHES.MATCH_TYPE <> 'cc')))

I want to replace the varaible

currently WHERE (((aa.new.GEO IN ('aa', 'bb')
                 AND (aaSTG_MATCHES.MATCH_TIMESTAMP >=
                         UserVar.DELTA_StartTime))
               AND (aaSTG_MATCHES.MATCH_TIMESTAMP < UserVar.DELTA_EndTime))
             AND (aaSTG_MATCHES.MATCH_TYPE <> 'cc')))

wants

WHERE (((aa.new.GEO IN ('aa', 'bb')
                 AND (aaSTG_MATCHES.MATCH_TIMESTAMP >=
                         select starttime from aa.STG_DELTA_TIMESTAMPS
where PROCESSKEY = 'Export Responses to MII'))
               AND (aaSTG_MATCHES.MATCH_TIMESTAMP < UserVar.DELTA_EndTime))
             AND (aaSTG_MATCHES.MATCH_TYPE <> 'cc')))

you want to use dynamic sql then?
something like
set var = 'WHERE (((aa.new.GEO IN ('aa', 'bb')
                 AND (aaSTG_MATCHES.MATCH_TIMESTAMP >= ' ||
                         UserVar.DELTA_StartTime || '))
               AND (aaSTG_MATCHES.MATCH_TIMESTAMP < UserVar.DELTA_EndTime))
             AND (aaSTG_MATCHES.MATCH_TYPE <> 'cc')))'

execute immediate var

Hi Sam,

The end time is built from the current Julian date and current time.  Current Timestamp should be a suitable substitute and not require the hoops that the code is jumping through.

The start time is read from the database (aaSTG_DELTA_TIMESTAMPS).  Simply substituting that query into the filter is equivalent to computing a variable and using the var.

WHERE (((aa.new.GEO IN ('aa', 'bb')
  AND (aaSTG_MATCHES.MATCH_TIMESTAMP >= (SELECT starttime FROM aaSTG_DELTA_TIMESTAMPS
                                         WHERE PROCESSKEY = 'Export Responses to MII')))
  AND (aaSTG_MATCHES.MATCH_TIMESTAMP < current_timestamp))
  AND (aaSTG_MATCHES.MATCH_TYPE <> 'cc')))

Open in new window


Does that solve things?
