Get SQL Query from the Region Source

Question

Hi,
The below query gives me the region source code,
SELECT region_source into p_sql_stmt
FROM apex_application_page_regions
WHERE region_id = 01129836282 AND
page_id = 54 AND
application_id = 215;
Initially I use to have only the SQL region source code as mentioned below , So using the above query i use to pass the sql code to p_sql_stmt
SELECT PROJECT_ID,EMPLOYEE_ID,EFFECTIVE_DATE FROM AR_V_ADDRESS_HISTORY WHERE PROJECT_ID = :P51_PROJECT_ID
Now the changes what i did in the page region source is i am using a PLSQL return query which is mentioned below
declare
qry varchar2(32000);
begin
qry := ' SELECT PROJECT_ID,EMPLOYEE_ID,EFFECTIVE_DATE';
for c1 in ( SELECT * FROM AR_ADDRESS_TYPE)
loop
qry := qry ||
' , GET_ADDRESS_LINE_1(PROJECT_ID,EMPLOYEE_ID,' || c1.address_type_id || ' ,TO_DATE(EFFECTIVE_DATE)) "' || c1.name ||'_ADDRESS_TYPE_1"';
qry := qry ||
' , GET_ADDRESS_LINE_1(PROJECT_ID,EMPLOYEE_ID,' || c1.address_type_id || ' ,TO_DATE(EFFECTIVE_DATE)) "' || c1.name ||'_ADDRESS_TYPE_2"';
end loop;
qry := qry || ' FROM AR_V_ADDRESS_HISTORY
WHERE
PROJECT_ID = :P51_PROJECT_ID ';
return(qry);
end;
If i execute the above code in the with dbms_output.put_line in the SQL developer or TOAD it prints the sql query which i wanted, Since i am using this in a apex page i need to get the SQL code from the apex page.
Can any one please suggest me how to get this sql code using the above plsql code.
Please suggest me in this issue
Thanks

One way to get the sql statement is
Create a global variable in the package spec where your function returns sql statement and assign the final sql statement to the package spec variable before the return.
Write a wrapper function to return the stored sql statement value.
Example code below:
create or replace package xx_test_pkg as
g_sql_stmt CLOB;
function get_sql() return clob;
function get_stored_val() return clob;
end;
create or replace body package xx_test_pkg as
function get_sql return clob ..
v_sqlstmt clob;
begin
v_sqlstmt := 'select * from emp';
-- assign to global variable before returning the value
g_sql_stmt := v_sqlstmt;
return v_sqlstmt;
end;
function get_stored_val() ....
begin
return g_sql_stmnt;
end;
end;
