Procedure to Search Entire Database:

    CREATE or REPLACE PROCEDURE SEARCH_DB(SEARCH_STR IN VARCHAR2, TAB_COL_RECS OUT VARCHAR2) IS
      match_count integer;
      qry_str varchar2(1000);
      CURSOR TAB_COL_CURSOR IS 
          SELECT TABLE_NAME,COLUMN_NAME,OWNER,DATA_TYPE FROM ALL_TAB_COLUMNS WHERE DATA_TYPE in ('NUMBER','VARCHAR2') AND OWNER='SCOTT';
          BEGIN  
            FOR TAB_COL_REC  IN TAB_COL_CURSOR
            LOOP
              qry_str := 'SELECT COUNT(*) FROM '||TAB_COL_REC.OWNER||'.'||TAB_COL_REC.TABLE_NAME|| 
              ' WHERE '||TAB_COL_REC.COLUMN_NAME;
               IF TAB_COL_REC.DATA_TYPE = 'NUMBER' THEN
                      qry_str := qry_str||'='||SEARCH_STR; 
               ELSE
                       qry_str := qry_str||' like '||SEARCH_STR; 
               END IF;
                       --dbms_output.put_line( qry_str );
                EXECUTE IMMEDIATE  qry_str  INTO match_count;
                IF match_count > 0 THEN          
                   dbms_output.put_line( qry_str );
                  --dbms_output.put_line( TAB_COL_REC.TABLE_NAME ||' '||TAB_COL_REC.COLUMN_NAME ||' '||match_count);     
                    TAB_COL_RECS := TAB_COL_RECS||'@@'||TAB_COL_REC.TABLE_NAME||'##'||TAB_COL_REC.COLUMN_NAME;
                END IF; 
          END LOOP;
     END SEARCH_DB;    

Execute Statement

  DECLARE
    SEARCH_STR VARCHAR2(200);
    TAB_COL_RECS VARCHAR2(200);
    BEGIN
      SEARCH_STR := 10;
      SEARCH_DB(
        SEARCH_STR => SEARCH_STR,
        TAB_COL_RECS => TAB_COL_RECS
      );
     DBMS_OUTPUT.PUT_LINE('TAB_COL_RECS = ' || TAB_COL_RECS);
     END;

Sample Results

Connecting to the database test.
SELECT COUNT(*) FROM SCOTT.EMP WHERE DEPTNO=10
SELECT COUNT(*) FROM SCOTT.DEPT WHERE DEPTNO=10
TAB_COL_RECS = @@EMP##DEPTNO@@DEPT##DEPTNO
Process exited.
