To PLSQL-sætninger med start og slut, kører fint hver for sig, men ikke sammen?

Oracle kan tage én SQL-sætning eller PL/SQL anonym blok ad gangen. (I modsætning til SQL Server, der kan undtage en batch ad gangen.) Så du har et par muligheder.

1. Pak de to anonyme blokke ind i en anden anonym blok:

   begin
     -- Make GC_NAB field for Next Action By Dropdown 
     begin 
     if 'VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')>0 then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10, ))'; 
     elsif ('VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')=0) or 
       'VARCHAR2' = 'VARCHAR2' then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10))'; 
     else 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2)'; 
     end if; 
     commit; 
     end; 
     -- Make GC_NABID field for Next Action By Dropdown 
     begin 
     if 'NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')>0 then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER(, ))'; 
     elsif ('NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')=0) or 
       'NUMBER' = 'VARCHAR2' then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER())'; 
     else 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER)'; 
     end if; 
     commit; 
     end;
   end;
   

2. Fortæl det værktøj, du bruger til at sende PL/SQL til Oracle, om at sende de to blokke separat. Hvordan man gør dette vil være værktøjsspecifikt. I SQL*PLUS, en / på en linje i sig selv vil opnå dette:

     -- Make GC_NAB field for Next Action By Dropdown 
     begin 
     if 'VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')>0 then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10, ))'; 
     elsif ('VARCHAR2' = 'NUMBER' and length('VARCHAR2')>0 and length('')=0) or 
       'VARCHAR2' = 'VARCHAR2' then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2(10))'; 
     else 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NAB VARCHAR2)'; 
     end if; 
     commit; 
     end; 
     /
     -- Make GC_NABID field for Next Action By Dropdown 
     begin 
     if 'NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')>0 then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER(, ))'; 
     elsif ('NUMBER' = 'NUMBER' and length('NUMBER')>0 and length('')=0) or 
       'NUMBER' = 'VARCHAR2' then 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER())'; 
     else 
       execute immediate 'alter table "SERVICEMAIL6"."ETD_GUESTCARE" add(GC_NABID NUMBER)'; 
     end if; 
     commit; 
     end;
     /
