How can I write code that uses schemas returned by one query to run another

Question

I need to use the data returned by this SQL
Select owner
From dba_tables
Where tablename = 'TRANSACT';
To run the following SQL for every schema in the database:
Select $vschema, count(*)
from $vschema..transact;
Where I am using $vschema as a variable to hold owners returned by the first statement.
I have tried using 1 cursor, 2 cursors, 1 coursor and an execute immediate command and either my code fails or I get a message that it ran successful but I cant see the data that I want returned by the second query.

Answer 1

I don't actually want to get the count on the transact table for each schema I just used that as an example to simplify... Maybe the code that I have written so far would be better... Here is one attempt:
SET SERVEROUTPUT ON SIZE 1000000
SET VERIFY OFF
DECLARE
v_schema Varchar2(50);
v_chgdate DATE;
v_debits NUMBER(14,4);
v_amount NUMBER(14,2);
/* First cursor */
CURSOR get_schemas (v_schema OUT char) IS
SELECT DISTINCT t.owner
FROM sys.dba_tables t
WHERE t.table_name = 'GERCVLOG'
ORDER BY t.owner;
/* Second cursor */
CURSOR get_stats (v_schema IN char) IS
SELECT MAX(g.chgdate),
SUM(g.debits),
SUM(g.totalamt)
FROM &&v_schema..gercvlog g
WHERE g.chgdate >= '01-Jan-07' or
g.chgdate = (SELECT MAX(g1.chgdate)
FROM &&v_schema..gercvlog g1);
BEGIN
/* Open first cursor*/
OPEN get_schemas (v_schema OUT char);
LOOP
FETCH get_schemas INTO v_schema;
EXIT WHEN get_schemas%NOTFOUND;
dbms_output.put_line('Schema: '||v_schema);
OPEN get_stats (v_schema IN char);
LOOP
FETCH get_stats INTO v_chgdate, v_debits, v_amount;
FETCH get_schemas INTO v_schema;
EXIT WHEN get_stats%NOTFOUND;
dbms_output.put_line('Latest Import: '||v_chgdate);
dbms_output.put_line('Total Debits: '||v_debits);
dbms_output.put_line('Total Dollars: '||v_amount);
dbms_output.put_line('______________________________');
END LOOP;
CLOSE get_stats;
END LOOP;
CLOSE get_schemas;
END;
