SQL Server Need to Handle NULL values inside Stuff function -


my required output should thisi have concatenate subavlues of multivalued record separator , if middle subvalue null have concatenate separator. have written following code.

select b.account_number ,b.co_code,(select case when other_officer not null ,  0 < (select count(c.account_number) efz_account_details c c.account_number = a.account_number , c.other_officer null ) isnull(b.other_officer +']',']') else null end efz_account_details     a.account_number = b.account_number     xml path(''))as acc_deb_limit efz_account_details b group account_number,co_code

this working, though subvalues of multivalued record null concatenating separator , output coming this

i display null incase subvalues null , need remove separator @ ending of string. please me in regard. in advance

i tried logic also, giving me same result

select account_number ,co_code, stuff(( select  isnull(']'+ other_officer,']') efz_account_details b.account_number = a.account_number xml path('')),1 ,1, '')  alt_account_type efz_account_details b group account_number,co_code;

i'm not sure if understood requirements, query solved problem.

select   case   when d null , c not null     isnull(a,'')+']'+isnull(b,'')+']'+ c  when d null , c null , b not null      isnull(a,'')+']'+ b  when d null , c null , b null , not null      when d null , c null , b null , null      null  else    isnull(a,'')+']'+isnull(']'+b,'')+']'+isnull(']'+c,'')+']'+isnull(d,'')+']'

end testtable;

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
