ORACLE表名與列名小寫轉成大寫


批量將表名變為大寫

begin
   for c in (select table_name tn from user_tables where table_name <> upper(table_name)) loop
       begin
          execute immediate 'alter table "'||c.tn||'" rename to '||c.tn;
       exception
          when others then
             dbms_output.put_line(c.tn||'已存在');
       end;
   end loop; 
end;

批量將空間內所有表的所有字段名變成大寫  此方法可能導致溢出

begin   
  for t in (select table_name tn from user_tables) loop
      begin
         for c in (select column_name cn from user_tab_columns where table_name=t.tn) loop
             begin
                execute immediate 'alter table "'||t.tn||'" rename column "'||c.cn||'" to '||c.cn;
             exception
                when others then
                   dbms_output.put_line(t.tn||'.'||c.cn||'已經存在');
             end;
         end loop;
      end;
  end loop; 
end;

  將特點表PROPERTY_INFO的所有列名小寫變大寫

begin
for c in (select COLUMN_NAME cn from all_tab_columns where table_name='PROPERTY_INFO') loop
begin
execute immediate 'alter table PROPERTY_INFO rename column "'||c.cn||'" to '||c.cn;
exception
when others then
dbms_output.put_line('PROPERTY_INFO'||'.'||c.cn||'已經存在');
end;
end loop;
end;
