SQL & PL/SQL :: Specifying INTO Inside Execute Immediate?
Jun 29, 2011
The following code works
set serveroutput on
declare
a int;
begin
execute immediate 'select employee_id from employees where first_name=:ab' into a using 'Donald' ;
dbms_output.put_line(a);
end;
but this one doesn't
set serveroutput on
declare
a int;
begin
execute immediate 'select employee_id into :1 from employees where first_name=:2' using a,'Donald';
dbms_output.put_line(a);
end;
Am I not allowed to specify a bind variable with an into clause inside execute immediate ?

I have a dynamic query which i want to run till it return zero records.
I am using WHILE loop for that but it is giving compilation error:
The query is
execute immediate ' Delete from tbl_archive_trade_list
where deal_id in (
select deal_id from tbl_archive_trade_list where trade_id in (
select trade_id from ' || main_trade_group_table || ' where tradegroup_id in (
select tradegroup_id from ' || main_trade_group_table || ' a , tbl_archive_trade_list b
[Code]...
I want to run this Query in While loop till the above command return 0 records.
I tried giving the above statement inside WHILE loop but it is failing.
Without the WHILE loop the above statement works fine and executed properly.

Requirement is to build procedure where it has 10-12 input variables but some of them (input variables) may at times be NULL.Based on this, i thought of getting into EXECUTE IMMEDIATE but this would just return rows i mean DML stmt for EXECUTE IMMEDIATE.Also, on the requirment is all parameters are present then result set be based on range on start and end date.

I'm working with old code that uses dbms_sql.execute to build/execute dynamic sql. In our case, the user can select varying columns(I think up to 20) with different where conditions as needed.
After building the sql, here's an example
WITH ph AS
(SELECT ph.* FROM po_header ph WHERE 1 = 2),
pf AS
(SELECT DISTINCT pf.order_id, pf.fund
FROM po_fau pf, ph
WHERE 1 = 1
AND ph.order_id = pf.order_id
[code]....
Where table records for
po_header = ~567746
po_fau = ~2153570
and PK "order_id" is a NUMBER(10) not null and a snippet of the code looks like
nDDL_Cursor := dbms_sql.open_cursor;
dbms_sql.parse(nDDL_Cursor, sSQLStr, 2);
FOR x IN 1 .. nCols LOOP
sCols(x) := '';
dbms_sql.define_column(nDDL_Cursor, x, sCols(x), 100);
END LOOP;
nError := dbms_sql.execute(nDDL_cursor);
why when the "execute" statement is fired off the elapsed time takes ~4.5 seconds but If I change "1 = 1" above to "1 = 2" it takes ~.2 seconds. If I run the above query interactively it takes ~.2 seconds. Shouldn't the above query when joining
ph.order_id = pf.order_id
return zero rows back instantly or does the "dbms_sql_execute" do some other type of parsing internally that takes cpu time.

We can execute dynamic sql using both execute immediate and ref cursor..But what is the difference between the two and performance-wise which is better?

I have a cursor returning some value.
for each value returned by the cursor i need to traverse through 31 rows(1 row per day * no of days in the month).
E.g. if cursor returns service_name as xyz then for xyz there can be 31 rows(service may not be used on some days)
I need to go to all of them and take some values and move them to a flat file. how should that be done?

I have an application written in Pl SQL Oracle which suppose to send email using utl_smtp. For users that are using Exchange Server 2010 Windows the hyperlinks inside the email are correctly but for users that have a Postfix version installed on a Debian 5 Linux mail server the hyperlinks contains some extra spaces. I think that the CRLF that I'm using inside my code to create the MIME message is not ok interpreted.

im calling an api inside a cursor.. for the first loop in a cursor , the api works well. however, for the rest of the loops the api doesn't give any error, but it doesn't insert any row to the table.
if i called the same api for every single value in a cursor seperately the api would insert all rows.

I can't understand the following cursor declaration (inside the DECLARE of a PL/SQL block)
CURSOR c_emps IS
SELECT emp_large_ot(empno, ename, job, mgr,hiredate, sal, comm, deptno) FROM emp_large;
emp_large_ot is an object type created as
CREATE TYPE emp_large_ot AS OBJECT
( empno NUMBER
, ename VARCHAR2(10)
, job VARCHAR2(9)
[code]...
and emp_large is similar to the standard emp table

I have a DML Statement inside a procedure and i use a cursor variable to get the values checked as below . I have attached my procedure not completely but the declaration part and the DML statement part.
The issue is my procedure is not inserting the records at all. It selects the values and then inserts accoringly but its not selecting because of the cursor reference R_LOC.LOCATION_GID.
when i hard code the value in the DML statemnt for the R_LOC.LOCATION_GID, the rows are inserted as expected. So i guess the way the procedure executes the value is not correct.
Modifying my select part which uses cursor variable R_LOC.LOCATION_GID under Insert statement.
select d.servprov_gid, d.depot_gid, replace(d.appointment_time,'':'') appmt_time, d.'||v_day_to_use||' DayUsed
from tesco_fresh_templates t, tesco_fresh_templates_d d, location_refnum r
where t.set_id= d.set_id
and d.depot_gid=r.location_gid
AND D.SERVPROV_GID=''R_LOC.LOCATION_GID''
and r.location_refnum_qual_gid=''TESCO.IVS SCHEDULING''
and (r.location_refnum_value=''YES'' or r.location_refnum_value=''Y'')
and t.default_set=''Y''

I need to sort values inside a column. Data in column is concat with '|' (pipe). There could be 1 to many values in one column.
The order of the rows is not relevant here.
Test case:
-------------
create table t1 (col1 varchar2(100));
insert into t1 values ('H302|H411|H317|H314|H312');
insert into t1 values ('H315|H410|H400|H318');
insert into t1 values ('H226|H400|H331|H318|H317|H315|H310|H301');
insert into t1 values ('H301');
commit;
select col1 from t1;
COL1
----------------------------------------
H302|H411|H317|H314|H312
H315|H410|H400|H318
H315|H318
H301
H226|H400|H331|H318|H317|H315|H310|H301
Need is this:
COL1
----------------------------------------
H302|H312|H314|H317|H411
H315|H318|H400|H410
H315|H318
H301
