-

i need access field of database table defined condition in query.i need access service_leg column , filter data column.

select  pa1.countryname, pw.serviceprovideractorwid, pa2.id, pw.orderid, pw.issorderref, po.modelcode, pw.itemid, pe1.eventcode starteventcode, pe2.eventcode endeventcode,   case    when pw.enddate < pof.retdate 'to_service'   else 'from service'   end "service_leg", pa1.roleid, pad.activitycode, pw.tat, pw.totelapse phwactivitydetail pw join phdactor pa1 on pa1.actorwid = pw.orderissactorwid join phdactor pa2 on pa2.actorwid = pw.serviceprovideractorwid join phdobject po on po.objectwid = pw.objectwid join phdevent pe1 on pe1.eventwid = pw.starteventwid join phdevent pe2 on pe2.eventwid = pw.endeventwid join phaorderflowcatch pof on pof.orderdid = pw.orderdid join phxactivitydef pad on pad.activitydefdid = pw.activitydefdid join gldcalendar gc on gc.datenum = pw.enddatenum;

thank you.

use outer sub-query achieve that.

demo:

select *   (     select      pa1.countryname,     pw.serviceprovideractorwid,     pa2.id,     pw.orderid,     pw.issorderref,     po.modelcode,     pw.itemid,     pe1.eventcode starteventcode,     pe2.eventcode endeventcode,       case        when pw.enddate < pof.retdate 'to_service'       else 'from service'       end "service_leg",     pa1.roleid,     pad.activitycode,     pw.tat,     pw.totelapse     phwactivitydetail pw     join phdactor pa1 on pa1.actorwid = pw.orderissactorwid     join phdactor pa2 on pa2.actorwid = pw.serviceprovideractorwid     join phdobject po on po.objectwid = pw.objectwid     join phdevent pe1 on pe1.eventwid = pw.starteventwid     join phdevent pe2 on pe2.eventwid = pw.endeventwid     join phaorderflowcatch pof on pof.orderdid = pw.orderdid     join phxactivitydef pad on pad.activitydefdid = pw.activitydefdid     join gldcalendar gc on gc.datenum = pw.enddatenum ) t t.service_leg > 100;

i'm trying code cyclic autocorrelation function in matlab follows: t=0:(n-1); t=t*te; i_alpha=0; tau=-n2*te:te:n2*te; alpha=-1/2:1/n:1/2; ryy_cl=zeros(length(alpha),length(tau)); alpha=alpha/te ind_tau=0; i_alpha=i_alpha+1; k=tau ind_tau=ind_tau+1; if k>0 % ryy_cl(i_alpha,ind_tau)=1/length(sig_bin_syl_mod(1:end- k))*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(1i*2*pi*alpha*t(1+k:length(sig_bin_syl_mod(1:end)))); ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(-1i*2*pi*alpha*t(1:end-k)); else ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1-k:end)).*sig_bin_syl_mod(1:end+k)).*exp(-1i*2*pi*alpha*t(1-k:end)); end end end i'm getting errors, , doesn't show expecting. according below formulae, how can fix it? the code provided incomplete, difficult confidently reproduce error. in particular, haven't de...
