Oracle查詢數據庫中某用戶下知足某些條件的表的記錄數

首先創建一個計算函數
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
create or replace function count_rows(table_name in varchar2,
                              owner in varchar2 default null)
return number
authid current_user
IS
   num_rows number;
   stmt varchar2(2000);
begin
   if owner is null then
      stmt := 'select count(*) from "'||table_name||'"';
   else
      stmt := 'select count(*) from "'||owner||'"."'||table_name||'"';
   end if;
   execute immediate stmt into num_rows;
   return num_rows;
end;
而後經過計算函數進行統計
select table_name, count_rows(table_name) nrows from user_tables

where table_name not in('IPRTT_SUB_POLICY','DC_SR_SUB_POLICY','TTIPR_POLICY','XWZ_POLICY','WZ_POLICY',
 'W_POLICY','IPTTC_COVERAGE_INFO','CYBTTC_COVERAGE','IPC_MO_CYB_TIMEPOINT','CYBTTC_COVERAGE_TEMP',
 'IPC_TEMP_CYB','IPC_TEMP_CYBWZX','CYBTT_SUB_POLICY','CYBCYBC_COVERAGE_REL','INSURANCES','IPCASUAL','IPCCYBCYB_COVERAGE_REL',
 'IPCOUNTERS','IPCYB_R_SUB_POLICY','IPTEST','SPERRORLOG','TEST','ITTPR_MONEYIN_INFO','IPSUB_POL_ID','IPDC_R_SUB_POLICY'
 ,'IPB_B_CALC_MDL','IPS_LOAN_RULE3')
 and  table_name not like'%TMP%'
獲取要統計的值

 

而後用UE比較

 

或者 select t.table_name,t.num_rows from user_tables t
查看記錄數，可是這種不許確。
仍是以爲上面的本身寫函數實現好些

declare
v_tName varchar(50);
v_sqlanalyze varchar(500);
v_num number;
v_sql varchar(500);
cursor c1 
is
select table_name from user_tables;
begin
open c1;
loop
fetch c1 into v_tName;
if c1%found then

v_sqlanalyze :='analyze table  '||v_tName||'  estimate statistics';
execute immediate v_sqlanalyze;
v_sql := 'select NUM_ROWS  from user_tables where table_name =upper('''||v_tName||''')';

execute immediate v_sql into  v_num;
dbms_output.put_line('表名： '||v_tName||' 行數： '||v_num);
else
exit;
end if;
end loop;
end;
