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;
