Is there a way to create multiple triggers in one script?

Question

I am trying to create multiple triggers with only uploading one script into an Oracle DB / APEX workspace, and running it once.

Here is a brief script compared to th

Answer 1

Add a forward slash on a new line after each trigger to execute the command in the buffer:

create trigger...
...
end;
/

Answer 2

Put a slash '/' as the first character on a blank line between each trigger statement. This is the SQL*PLUS equivalent of 'go'.

Answer 3

Yes we can execute multiple procedure/trigger/function in single script using the FORWARD SLASH / inside the sql file.

Like below:

create or replace trigger "BI_TEC_ROLES"   
      before insert on "TEC_ROLES"               
      for each row  
    begin   
      if :NEW."ROLE_ID" is null then 
        select "TEC_ROLES_SEQ".nextval into :NEW."ROLE_ID" from dual; 
      end if; 
    end; 

/
    create or replace trigger "BI_TEC_STATUSES"   
      before insert on "TEC_STATUSES"               
      for each row  
    begin   
      if :NEW."STATUS_ID" is null then 
        select "TEC_STATUSES_SEQ".nextval into :NEW."STATUS_ID" from dual; 
      end if; 
    end; 

/

   create or replace trigger "BI_TEC_SUBS"   
      before insert on "TEC_SUBS"               
      for each row  
    begin   
      if :NEW."SUB_ID" is null then 
        select "TEC_SUBS_SEQ".nextval into :NEW."SUB_ID" from dual; 
      end if; 
    end; 

/

Then oracle will consider it as new statement/block.

Answer 4

Place a forward slash

/

between the two statements on a separate line.

Oracle will then accept it as a new statement
