試試這個：

SELECT 'select * from ' || table_name || ' where ' || clause 
    FROM (SELECT DISTINCT REPLACE(stragg(column_name) 
            over(PARTITION BY table_name ORDER BY table_name), ',', 
            ' = ''__your_string__'' OR ') || ' = __your_string__' clause, 
         table_name 
      FROM user_tab_columns 
      WHERE table_name IN 
       (SELECT table_name 
        FROM all_constraints 
        WHERE constraint_type = 'R' 
        AND r_constraint_name IN (SELECT constraint_name 
               FROM all_constraints 
               WHERE constraint_type IN ('P', 'U') 
               AND table_name = '__yout_table__'))); 

另外，你必須把它包在PLSQL或循環以某種方式來執行記錄集的每一行。
