Oracle 中 根据值 查询 所在 表和字段
---------------------- 这里是查询 数字型字段值/*declareCURSOR cur_query IS select table_name, column_name, data_type from user_tab_columns; a number; sql_hard varchar2(2000); vv number;begin for rec1 in cur_query loop a:=0; if rec1.data_type =‘NUMBER‘ THEN a := 1; end if; if a>0 then sql_hard := ‘‘; sql_hard := ‘SELECT count(*) FROM ‘|| rec1.table_name ||‘ where ‘ ||rec1.column_name|| ‘=‘‘TYRCE0BF26AB5C586B3 ‘‘ ‘; dbms_output.put_line(sql_hard); execute immediate sql_hard INTO vv; IF vv > 0 THEN dbms_output.put_line(rec1.table_name||‘--‘||rec1.column_name); end if; END IF; end loop;end;*/
查询字符串类型:
declareCURSOR cur_query IS select a.table_name, a.column_name, a.data_type from user_tab_columns a where 1=1 and (lower(a.data_type) = ‘varchar2‘ or lower(a.data_type) = ‘char‘) and NOT a.TABLE_NAME like ‘%$%‘ and NOT a.TABLE_NAME like ‘%+%‘ and NOT a.TABLE_NAME like ‘%=%‘ ORDER BY A.TABLE_NAME ASC ; a number; sql_hard varchar2(2000); vv number; rscount number; str varchar2(2000); num number; findValue varchar2(500) :=‘R2186E3DC09B88E1AF ‘; -- 要查询的字符串值begin rscount:=0; str:=‘TRUNCATE table tmp_test‘; execute immediate str; str:=‘drop table tmp_test‘; execute immediate str; str:=‘CREATE GLOBAL TEMPORARY TABLE tmp_test (tab_name varchar2(500), col_name varchar2(500)) ON COMMIT PRESERVE ROWS‘; execute immediate str; ----使用动态SQL语句来执行 for rec1 in cur_query loop rscount:= rscount + 1; a:=0; --if rec1.data_type =‘VARCHAR2‘ or rec1.data_type=‘CHAR‘ THEN if rec1.data_type =‘VARCHAR2‘ or rec1.data_type=‘CHAR‘ THEN a := 1; end if; if a>0 then sql_hard := ‘‘; sql_hard := ‘SELECT count(*) FROM ‘|| rec1.table_name ||‘ where ‘ --||rec1.column_name|| ‘ =‘‘wu‘‘‘; ||rec1.column_name|| ‘ =‘‘‘|| findValue || ‘‘‘‘; --dbms_output.put_line(sql_hard); --dbms_output.put_line( ‘**** ‘ || rec1.table_name||‘--‘||rec1.column_name); execute immediate sql_hard INTO vv; IF NVL(vv,0) > 0 THEN dbms_output.put_line(rec1.table_name||‘--‘||rec1.column_name); str:= ‘insert into tmp_test ‘ || ‘ select ‘‘‘ || rec1.table_name || ‘‘‘ as tab_name,‘‘‘ || rec1.column_name || ‘‘‘ as col_name from dual‘; execute immediate str; str:= ‘commit‘; execute immediate str; end if; END IF; end loop; --str:= ‘select * from tmp_test‘; --execute immediate str; end;-- 运行完以后 执行/*select * from tmp_test;*/
