Oracle-procedure om tabelnamen en bijbehorende telling weer te geven

Ik weet niet zeker wat hier precies de vereiste is, maar u kunt de volgende benadering gebruiken om het aantal records uit elke tabel op te halen.

SQL> -- This is sample data
SQL> WITH SAMPLE_DATA(TNAME) AS
  2  (SELECT 'CUSTOMERS' FROM DUAL UNION ALL
  3  SELECT 'INTERVAL_TAB' FROM DUAL)
  4  -- Your query starts from here
  5  SELECT TABLE_NAME,
  6         TO_NUMBER(
  7         EXTRACTVALUE( XMLTYPE(
  8         DBMS_XMLGEN.GETXML('select count(*) c from ' || U.TABLE_NAME)
  9         ), '/ROWSET/ROW/C')) COUNT
 10    FROM USER_TABLES U JOIN SAMPLE_DATA S ON S.TNAME = U.TABLE_NAME;

TABLE_NAME           COUNT
--------------- ----------
CUSTOMERS                1
INTERVAL_TAB             0

U kunt de weergave als volgt genereren:

-- DIT SECTIE BIJGEWERKT

CREATE OR REPLACE VIEW V_CHECK_RECORDS_AUS AS
SELECT TABLE_NAME,
       TO_NUMBER(
           EXTRACTVALUE( XMLTYPE(
                   DBMS_XMLGEN.GETXML('select count(*) c from ' 
                      || U.TABLE_NAME || ' WHERE oe_name=''BUL''')
               ), '/ROWSET/ROW/C')) NUM_ROWS
  FROM USER_TAB_COLUMNS U JOIN GD_TABLE_ORDER S ON S.TABLE_NAME_AUS = U.TABLE_NAME 
 WHERE U.COLUMN_NAME = 'OE_NAME';

Op dezelfde manier kunt u andere weergaven genereren.

-- Verdere update

CREATE OR REPLACE VIEW V_CHECK_RECORDS_AUS AS
SELECT TABLE_NAME,
       CASE WHEN U.COLUMN_NAME IS NOT NULL THEN TO_NUMBER(
           EXTRACTVALUE( XMLTYPE(
                   DBMS_XMLGEN.GETXML('select count(*) c from ' 
                      || U.TABLE_NAME || ' WHERE ' || U.COLUMN_NAME || '=''BUL''')
               ), '/ROWSET/ROW/C')) 
         ELSE 0 END NUM_ROWS
  FROM GD_TABLE_ORDER S LEFT JOIN USER_TAB_COLUMNS U 
  ON S.TABLE_NAME_AUS = U.TABLE_NAME AND U.COLUMN_NAME = 'OE_NAME';
