Using BIND VARIABLES in REF CURSOR(s)

Hello I am having trouble making my pl/sql program work using bind variables.
here is a little snipit from my code:
declare
type ref_type is REF CURSOR;
ref_cursor ref_type;
summation_table varchar2(4000);
begin
summation_table := 'table_sum tsum';
open ref_cursor for
select * from :summation_table
where tsum.revenue = 1000
USING summation_table;
end;
The Error that I get is
"bad bind variable 'summation_table'"
could someone please help? I think the way 'tsum' is used could be a problem, but I don't know.

SQL> CREATE TABLE TABLE_SUM(REVENUE NUMBER(10),
2                         OTHER   NUMBER(10));

Using bind variable for ref cursors

Hi
I have a procedure that recieves a tablename in srcTable variable . A query is formed SELECT_Q with values from global varray.
Table name will be dynamic and query is to be used with a ref cursor. Since table name is not known how to make the refcursor.
tried the following.....not sure how to do it. pls help.
PROCEDURE Process1(srcTable VARCHAR2, trgTable VARCHAR2) IS
     TYPE CURSORTYPE IS REF CURSOR RETURN :x%ROWTYPE;
     REC_CUR CURSORTYPE;
     REC_CUR_DATA :x%ROWTYPE;
     DBMS_SQL.BIND_VARIABLE(REC_CUR, ':x', SourceT);
     DBMS_SQL.BIND_VARIABLE(REC_CUR_DATA, ':x', SourceT);
     COUNTi NUMBER :=0;
     SELECT_Q VARCHAR2(1000) := 'SELECT ';
BEGIN
FOR COUNTi IN 1..COLUMN_NAME_ARR.COUNT-1 LOOP
          SELECT_Q := SELECT_Q || COLUMN_NAME_ARR(COUNTi) || ',';
END LOOP;
     SELECT_Q := SELECT_Q || COLUMN_NAME_ARR(COLUMN_NAME_ARR.COUNT) || ' FROM '||SourceT;
     DBMS_OUTPUT.PUT_LINE(SELECT_Q);
-- query to be used for making cursor.
---how to make the cursor
     OPEN REC_CUR FOR Select_Q;
     LOOP
     FETCH REC_CUR INTO REC_CUR_DATA;

I'm not much clear with the first approach,so I'm thinking of to modify my procedure as below

     ORDER BY upload_date DESC ;
     alter session set cursor_sharing=exact;
END;
/Please let me know if the above modified code is fine or should I use bind variables??Also let me know better approach of both.

The correct way to do this is use an array type for the input values as in this example.

How to use bind variable

Hi,
I have the below cursor 1 which is working already.For my requirement i want to use bind variable like second cursor.But its telling Bind Variable "p_col_list" is NOT DECLARED.Please any onehelp me on this.
How to use bind variable Here.
Cursor1:
DECLARE
emp_cv sys_refcursor;
iid NUMBER := 1;
i_sql varchar2(100);
p_col_list varchar2(2000) := 'aaa,bbb,ccc,ddd';
BEGIN
i_sql := 'select '''||REPLACE(p_col_list, ',', ''',''')||''' from dual '||CHR(10) ;
dbms_output.put_line(i_sql);
OPEN emp_cv FOR i_sql ;
END;

ORA-01006 Using Bind Variables In A Dynamic SQL Contains Query

I have the following dynamic SQL query :-
declare
TYPE typ_sql IS REF CURSOR;
ltyp_sql typ_sql;
lv_sql VARCHAR2(100);
begin
lv_sql := 'SELECT arx_id FROM arx WHERE CONTAINS ';
lv_sql := lv_sql || (arx_full,''(:b1) WITHIN ui'') > 0';
open ltyp_sql FOR v_sql USING ln_id;
fetch ......
close ......
end;
When the code tries to open the cursor it gives the above error. I presume it is the way Oracle is expanding the bind variable but I cannot find anything in the docs to say why this is happening or whether you can do this or not using bind variables ( CONTAINS query ). Any help would be appreciated, thanks,
Stuart.

lv_sql || '(arx_full, :b1 || '' within ui'') > 0';

I'm having a bit of trouble creating a report. I need the FROM part of the code to use bind variables. I have come up with this peice of code below but im getting the following error:

Hey Roel and Daylocks,
After getting frustrated for a while i deleted the page and started again. I put in the exact same code and it worked just how i wanted in the first place :S
The only thing i did different is when i was creating the report region the first time around i used a normal SQL query, For Example:
select sysdate from dual;
Then i modified it to
DECLARE
x VARCHAR2 (4000);
BEGIN
x := x || 'select ';*
x := x || 'from ';
x := x || :p14_schema;
x := x || '.ddl_log@';
x := x || :p14_db_name;
x := x || '_DBAAPEX.TNTEWW.COM';
RETURN (x);
END;
Whereas on the second attempt i used the peice of code in question straight away. Its been a bit of a frustrating morning because i used a similar peice of code for a different application, nevermind tho :)
Thanks for your replys, much appreciated.

Query don't use the right index when using bind variables

Hi people !
I need some help because I have an issue with a query that don t use the right Indexes as it should
First of all, I have mainly three tables :
ORDER : Table that contains description for each Order (approximately 1 000 000 Records)
ORDER_MVTS : Table that contains the tasks made (called movements) to set up each Orders
with quantity of packages prepared for each product (approximately 10 000 000 Records)
PRODUCT : Tables that contains the products (approximately 50 000 Records)
When I launch the query with hard coded values, it brings back response very fast
because it uses the right index (ORDER_DHR_VALID) which represent the date and hour of the order
(with format 'DD/MM/YYYY HH24:MI:SS'). The selectivity for this index is good.
NB 1: I have to use the trick " >= Trunc(date) and < trunc(date) +1 " to filter on a simple date because
the index contains hour and minutes (I know it wasn't probably a bright idea at conception time).
NB 2: The index on ORDER_MVTS.PRODUCT_CODE is'nt discriminating enough because there is'nt enough different products.
It's the same for index on CUSTOMER_CODE and on MVT_TYPE so only the index on ORDER.DHR_VALID is good.
Here is the correct explain plan when I execute the query with hard coded values :
SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS'))
AND ORDER.DHR_VALID < TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS')) + 1
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = 'ADIDAS'
AND PRODUCT.CODE = 1234
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
4 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
4 TABLE ACCESS BY INDEX ROWID ORDER
777 INDEX RANGE SCAN (object id 378119) --> ORDER_DHR_VALID
2 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
30 INDEX RANGE SCAN (object id 377784) --> ORDER_MVTS_ORDER_FK
Now the problem is when the query is used in a Cursor with bind variables.
It seems like Oracle don't use index on ORDER.DHR_VALID because he can't figure out that he have
to actually filter on a short period of time (only one day).
So Oracle uses the index on ORDER_MVTS.PRODUCT_CODE which is'nt a bright idea (it takes 10 secondes instead of just one)
Here is the bad explain plan :
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
722 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
722 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
1790 INDEX RANGE SCAN (object id 377777) --> ORDER_MVTS_PRODUCT_FK
2 TABLE ACCESS BY INDEX ROWID ORDER
1442 INDEX UNIQUE SCAN (object id 378439) --> ORDER_PK
Now I have found two solutions to this problem :
1) using a Hint to force the use of index on ORDER.DHR_VALID (with /*+ INDEX(ORDER ORDER_DHR_VALID) */ )
2) Using Dynamic SQL and keeping the date hard coded (but not the other values except mvt_type)
For example :
QUERY :=
'SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) '||
AND ORDER.DHR_VALID < TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) + 1 '||
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = :CUSTOMER
AND PRODUCT.CODE = :CODE ';
These two solutions work but Number 1 is bad in theory because it uses a Hint
and Number 2 may be difficult to code.
So my question is : Does someone knows another solution to force the use of index ORDER_DHR_VALID that can be simple and reliable.
Thank you very much for support

What version of oracle you have? CBO work is different in 9i and 10g.
Usually cost based optimizer do not want to use index for >< condition with binding variables because optimizer can not use statistic to determine selectivity, and by default selectivity of <> operators is low.
(As I remember '>' selectivity by default is 5%, you have two conditions > and <, therefore resulting selectivity will be 0.05*0.05=0.0025 as two independent events, but selectivity of other conditions
ORDER_MVTS.MVT_TYPE = 'DELIVERY' or ORDER.CUSTOMER_CODE = 'ADIDAS' looks much better for CBO)
The best solution I see is do not use binding variables. Actually your query looks as searching query, which executes not so often, therefore you will not have perfomance win along of skipping execution plan creation.

You cannot avoid hard parsing - as the 1st time a SQL statement (like the SELECT or DELETE statements in your code) is encountered, it does not reside in the server's Shared Pool, and needs to be added into the pool via a hard parse.
Bind variables does not prevent hard parsing. Hard parsing happens when the SQL statement (with or without bind variables) is a brand new statement encountered by the server.
Bind variables enables the same SQL cursor to be reused, by simply changing the bind variable value.
Not using bind variables means that each SQL statement is unique and not shareable - as the value is hardcoded into the statement and cannot be changed via a bind value. This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

How to use bind variables in desc flexfields in OA pages?

Use case: In EBS 11i we have a DFF on po_vendors and one of the segment has a table validated value set that is referencing a forms variable i.e :VENDORS.VENDOR_ID. Now after upgrading to R12 this won't work as the vendor pages moved to OA framework. Is there any way to reference the vendor_id column in OA framework?

This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

Possible for Oracle to consider constraints when using bind variable?

Consider the following table with a check constraint listing the possible values of the column
create table TEST_TABLE(
my_column varchar2(10));
insert into TEST_TABLE select 'VALUE1' from dba_objects;
alter table TEST_TABLE
add constraint TEST_TABLE_CHK1
check (my_column in ('VALUE1', 'VALUE2'));
begin dbms_stats.gather_table_stats(ownname=>user,tabname=>'TEST_TABLE');END;Let's see the number of logical I/O's needed for the following SQL statements.
(The value was obtained by the delta ofselect m.value from v$mystat m, v$statname n
where name='session logical reads' and m.statistic#=n.statistic#)
If string lateral is used:
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE1';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE2';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE3';
end;
Consistent Gets: 0Oracle can eliminate the table if it knows the queried value can't satisfy the constraint. Good.
(Actually, the execution plan for the last query included the 'FILTER' operation.)
However, if bind variable is used:
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE1';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE3';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21Oracle can't eliminate the table using the constraint. I can understand that because bind variables are used, Oracle can't directly eliminate the table when generating the execution plan. However, is it possible to eliminate the table, or at least employ some shortcut in runtime? If not, will this be a performance loss compared with using values laterals when check constraint exists?
(And is it possible to use autotrace on PL/SQL block in sqlplus?)
Oracle:
     10.2.0.4 SE
     11.2.0.2 SE
OS:
     RHEL5

However, is it possible to eliminate the table, or at least employ some shortcut in runtime? I can't see how to do this. Oracle has a sqltext that has an embedded bind variable in it. And for this sqltext it has an execution plan in the shared pool that will be used irrespective of the actual bound values at runtime.
Maybe in 11G, with adaptive cursor sharing / plan bind awareness, Oracle might be smart enough to introduce a second execution plan for the VALUE3 case.
If not, will this be a performance loss compared with using values laterals when check constraint exists?Only if you submit the dumb query and search for records with VALUE3... Normally your application code would not hold/generate these queries.
Will it?
For columns whose values are bound by a CHECK constraint, one might even consider to never use bind variables, since very likely you will have few versions of queries that use these columns.
Not?

Csv no data found when using bind variables

Hi,
I have created a report, that uses 2 date variables to limit the query and rows display as they should. But clicking the csv link opens csv having one row stating 'No data found...'. If I set static values in place of variables, I get the right result. How could I use bind variables and get the right answer in csv (without coding my own function)?
Kaja

I am having the same problem.
The export link opens a new session without submitting the current page. The page item values are therefor not saved to cache before the export is undertaken.
Any report using page item bind variables in the where clause will not export correctly as the bind values are either null or those of the previous page submit.
Any ideas on how to get round this??

Using Bind Variable in a SELECT

Hi,
I'm trying to build up my SQL query at run-time using bind variables and in the Oracle® Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework 11g Release 1 (11.1.1) it says that 'After defining the bind variables, the next step is to reference them in the SQL statement. While SQL syntax allows bind variables to appear both in the SELECT list and in the WHERE clause, you'll typically use them in the latter context, as part of your WHERE clause.'.
However, when I try to use the bind variables in my SELECT list because I've had to set a type for the variable to String the variable gets inserted with inverted commas either side e.g. SELECT 'Service' FROM TestTable. Is it possible to use bind variables to insert a value into my select list without these inverted commas around it?
Thanks in advance,
Tom

OK, thanks for your response. Do you know of a way then where I can control my SELECT parameters programmatically? I'm currently trying to do it using the information in the chapter '35.9 Using Programmatic View Objects for Alternative Data Sources' from the Oracle® Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework 11g Release 1 (11.1.1). I think I'm part way there, would this be the correct way of acheiving what I want?
Cheers, Tom

Using bind variable with IN clause

My application runs a limited number of straight up queries (no stored procs) using ODP.NET. For the most part, I'm able to use bind variables to help with query caching, etc... but I'm at a loss as to how to use bind variables with IN clauses. Basically, I'm looking for something like this:
int objectId = 123;
string[] listOfValues = { "a", "b", "c"};
OracleCommand command = new OracleCommand();
command.Connection = conn;
command.BindByName = true;
command.CommandText = @"select blah from mytable where objectId = :objectId and somevalue in (:listOfValues)";
command.Parameters.Add("objectId", objectId);
command.Parameters.Add("listOfValues", listOfValues);
I haven't had much luck yet using an array as a bind variable. Do I need to pass it in as a PL/SQL associative array? Cast the values to a TABLE?
Thanks,
Nick

Trying to pass array to stored procedure in a loop using bind variable

All,
I'm having trouble figuring out if I can do the following:
I have a stored procedure as follows:
create procedure enque_f826_utility_q (inpayload IN f826_utility_payload, msgid out RAW) is
enqopt dbms_aq.enqueue_options_t;
mprop dbms_aq.message_properties_t;
begin
dbms_aq.enqueue(queue_name=>'f826_utility_queue',
enqueue_options=>enqopt,
message_properties=>mprop,
payload=>inpayload,
msgid=>msgid);
end;
The above compiles cleanly.
The first parameter "inpayload" a database type something like the following:
create or replace type f826_utility_payload as object
2 (
3 YEAR NUMBER(4,0),
4 MONTH NUMBER(2,0),
83 MUSTHAVE CHAR(1)
84 );
I'd like to call the stored procedure enque_f826_utility_q in a loop passing to it
each time, new values in the inpayload parameter.
My questions are:
First, I'm not sure in php, how to construct the first parameter which is a database type.
Can I just make an associative array variable with the keys of the array the same as the columns of the database type shown above and then pass that array to the stored procedure?
Second, is it possible to parse a statement that calls the enque_f826_utility_q procedure using bind variables and then execute the call to the stored procedure in a loop passing new bind variables each time?
I've tried something like the following but it's not working:
$conn = oci_pconnect (....);
$stmt = "select * from f826_utility";
$stid = oci_parse($conn, $sqlstmt);
$r = oci_execute($stid, OCI_DEFAULT);
$row = array();
$msgid = "";
$enqstmt = "call enque_f826_utility_q(:RID,:MID)";
$enqstid = oci_parse($conn, $sqlstmt);
oci_bind_by_name($enqstid, ":RID", $row); /* line 57 */
oci_bind_by_name($enqstid, ":MID", $msgid);
while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS+OCI_ASSOC))
++$rowcnt;
if (! oci_execute($enqstid)) /* line 65 */
echo "Error";
exit;
When I run this, I get the following:
PHP Notice: Array to string conversion in C:\Temp\enqueue_f826_utility.php on l
ine 57
Entering loop to process records from F826_UTIITY table
PHP Notice: Array to string conversion in C:\Temp\enqueue_f826_utility.php on l

e 65
PHP Notice: Undefined variable: msgnum in C:\Temp\enqueue_f826_utility.php on l
ine 68

Exiting!

Thanks for the reply.
I took a look at this article. What it appears to describe is
a calling a stored procedure that takes a collection type which is an array.
Does anyone from Oracle know if I can pass other database type definitions to a stored procedure from PHP?
I have a type defined in my database similar to the following which is not
an array but a record of various fields. This type corresponds to a payload
of an advanced queue payload type. I have a stored procedure which will take as it's input, a payload type of this structure and then enqueue it to a queue.
So I want to be able to pass a database type similar to the following type definition from within PHP. Can anyone from Oracle verify whether or not this is possible?
create or replace type f826_utility_payload as object
YEAR NUMBER(4,0),
MONTH NUMBER(2,0),
UTILITY_ID NUMBER(10,0),
SUBMIT_FAIL_BY VARCHAR2(30),
MUSTHAVE CHAR(1)
);
