Two PLSQL statements with begin and end, run fine separately but not together?

Question

Just wondering if anyone can help with this, I have two PLSQL statements for altering tables (adding extra fields) and they are as follows:

-- Make GC_NAB fi         


        

Answer 1

Yes, you need a slash / on the line after each end;.

Answer 2

one can achieve in two ways

1) run the two blocks separately in pl/sql file.

2) in main block you can run two sbu-blocks in this way :

begin  // main block
      begin 
       .....   [pl/sql commands]
       ......
      end
      begin   
      .......  [pl/sql commands]
      .......
      end
end // main ends

Answer 3

Oracle can take one SQL statement or PL/SQL anonymous block at a time. (Unlike SQL Server that can except a batch at a time.) So, you have a couple of options.

1. Wrap the two anonymous blocks within another anonymous block:

   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. Tell the tool you are using to submit the PL/SQL to Oracle to send the two block seperately. How to do this will be tool specific. In SQL*PLUS, a / on a line by itself will accomplish this:

     -- 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;
     /
