I’m sorting out a series of SQL scripts for my company written in Oracle

  • 0

I’m sorting out a series of SQL scripts for my company written in Oracle PL/SQL. I came across an essential script with a strangely placed slash near the bottom. It is checked into CVS this way. Is this a pure syntax error or does it have some function I’m not aware of. The slightly obfuscated script:

set serveroutput on size 2000; --PL/SQL block to link ISSN in serial base on a company's ISSN text file  declare     cursor ItemCursor is         select issn is2 from web.obfuscated1 where issn is not null             union         select eissn is2 from web.obfuscated1 where eissn is not null;      cursor ItemCursor1(aIS varchar2) is         select obfuscated1_uid from web.obfuscated1 where group_num is null and issn in (             select distinct issn from web.obfuscated1 where issn = aIS or eissn = aIS                 union             select distinct eissn from web.obfuscated1 where issn = aIS or eissn = aIS         )             union         select obfuscated1_uid from web.obfuscated1 where eissn in (             select distinct issn from web.obfuscated1 where issn = aIS or eissn = aIS                 union             select distinct eissn from web.obfuscated1 where issn = aIS or eissn = aIS         );      cursor ItemCursor2(aIS9 varchar2) is         select obfuscated1_uid from web.obfuscated1 where issn in (             select distinct issn from web.obfuscated1 where issn = aIS9 or eissn = aIS9                 union             select distinct eissn from web.obfuscated1 where issn = aIS9 or eissn = aIS9         ) and group_num is null;      agroup      number(8);     processCount    number(8);      ------------------------------------------------------     -- MAIN BLOCK -----------------------------------     ------------------------------------------------- begin     processCount := 0;      agroup := null;     for itemRec in ItemCursor loop         agroup := null;         begin             select group_num into agroup from web.obfuscated1 where issn in (                 select distinct issn from web.obfuscated1 where issn = itemRec.is2 or eissn = itemRec.is2                     union                 select distinct eissn from web.obfuscated1 where issn = itemRec.is2 or eissn = itemRec.is2             ) and group_num is not null and issn is not null and eissn is not null and rownum <= 1;          exception             when no_data_found then                 agroup := null;             when others then                 agroup := null;         end;          if agroup is not null then             for itemRec2 in ItemCursor2(itemRec.is2) loop                 update web.obfuscated1 set group_num = agroup where obfuscated1_uid = itemRec2.obfuscated1_uid;                 commit;             end loop;         else             processCount := processCount + 1;             for itemRec1 in ItemCursor1(itemRec.is2) loop                 update web.obfuscated1 set group_num = processCount where obfuscated1_uid = itemRec1.obfuscated1_uid;                 commit;             end loop;             commit;         end if;     end loop;      dbms_output.put_line('Total record read: ' || processCount); exception     when others then         dbms_output.put_line('ORA' || sqlcode);         dbms_output.put_line(substr(sqlerrm, 1, 255));         dbms_output.put_line('ORA- Error during processing ' );     end; / exit;

  1. The slash has a meaning:

    Executes the most recently executed SQL command or PL/SQL block which is stored in the SQL buffer. You can enter a slash (/) at the command prompt or at a line number prompt of a multi-line command. The slash command functions similarly to RUN, but does not list the command.
