如何在SQL*Plus中使用begin/end运行Oracle查询？

Question

我创建了一个带有begin/end的查询块,并希望在SQL*Plus中运行它.但是如何在命令行中运行它？

实际上代码来自某个博客,它用于搜索数据库中的文本.ABC是要搜索的文本.

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 varchar2(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;

但这永远不会运行.我该如何运行代码？

Answer 1

你需要像斜线一样跟着它

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

Answer 2

你可能只需要在一行上单独使用一个"/"来使它执行.
