How to run Oracle query with begin/end in SQL*Plus?

I have created a query block with begin/end and want to run that in SQL*Plus. But how can I run it in the command line?

Actually the code is from some blog and it is used for searching text in the database. ABC is the texts to be searched.

set serveroutput on size 1000000
declare
TYPE QueryCurType is REF CURSOR;
query1 QueryCurType ;

cursor c1 is select owner,table_name from dba_tables where owner not in ('SYS','SYSTEM') and table_name not like '%$%';
cursor c2(t1 varchar2) is select column_name from dba_tab_columns where table_name=t1 and DATA_TYPE in ('NVARCHAR2','VARCHAR2','CHAR');
temp_var varchar2(3000);
query va开发者_运维百科rchar2(3000);

begin
for tab1 in c1 loop
  for col in c2(tab1.table_name) loop
    query:='select '||col.column_name||' from '||tab1.owner||'.'||tab1.table_name||' where '||col.column_name||' like "ABC"';
    --dbms_output.put_line('executing..'||query);
    open query1 for query;
    loop
      fetch query1 into temp_var;
      if concat('a',temp_var) != 'a' then
      dbms_output.put_line('Found String: "'||temp_var||'"# Column:'||col.column_name||'# Table:'||tab1.table_name);
      end if;
      exit when query1%NOTFOUND;
    end loop;
  end loop;
end loop;
end;

but this never gets run. How can I run the codes?

You need to follow it with a slash like

begin
  dbms_output.put_line('Hello World');
end;
/

You probably just need a "/" on a line by itself at the end to make it execute.
