## search for string in entire set of tables of a db

``` sql
SET SERVEROUTPUT ON SIZE 100000

DECLARE
  match_count INTEGER;
BEGIN
  FOR t IN (SELECT owner, table_name, column_name
              FROM all_tab_columns
              WHERE owner = 'APLKN_ARCHV_SRG' and data_type LIKE '%CHAR%' AND table_name like 'TB%') LOOP

    EXECUTE IMMEDIATE
      'SELECT COUNT(*) FROM ' || t.owner || '.' || t.table_name ||
      ' WHERE '||t.column_name||' like :1'
      INTO match_count
      USING '%Schrank ganz hinten%';

    IF match_count > 0 THEN
      dbms_output.put_line( t.owner ||' --- '||t.table_name ||' --- '||t.column_name||' --- '||match_count );
    END IF;

  END LOOP;

END;
```

or, without owner:

``` sql
SET SERVEROUTPUT ON SIZE 100000
DECLARE
  match_count INTEGER;
BEGIN
  FOR t IN (SELECT TABLE_NAME, COLUMN_NAME
              FROM all_tab_columns
              WHERE data_type LIKE '%CHAR%' AND TABLE_NAME LIKE 'TB%') LOOP
 
    EXECUTE IMMEDIATE
      'SELECT COUNT(*) FROM ' || t.TABLE_NAME ||
      ' WHERE '||t.COLUMN_NAME||' like :1'
      INTO match_count
      USING 'Conclusion of Peace between Russia and Esthonia%';
 
  IF match_count > 0 THEN
      dbms_output.put_line( t.TABLE_NAME ||' --- '||t.COLUMN_NAME||' --- '||match_count );
 END IF;
 
  END LOOP;
 
END;
```
