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

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))
