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';

Using bind variables in additional pl/sql code
How do you retrieve the a bind variable in the addition pl/sql
code portion of the report wizard?
I try something like
declare
v_test varchar2(40);
begin
select lastname into v_test from wvgsemp
where username = :binduser;
htp.bold('Report generated by:
'||v_test);
end;
but it say PLS-00049: bad bind variable 'BINDUSER'
However this is exactly the way I declared it in step one
of the wizard?Hi,
You cannot have bind variables in additional plsql code.
Thanks,

Regarding usage of constants while using bind variables
Hi All,
Can some one please help me out of this situation?
I wrote a query in a package in which i am using bind variables for faster execution of the query in loops.
In the above said scenario i am trying to insert a set of data into a table say 'A' by selecting from some other table say 'B'. But i also need to insert some data which is constant.
Something like this:
constant_val varchar2(1):='N';
for i in 1 .. tab.count
loop
insert into A(Col1, Col2) values (select constant_val, B.value from B where B.value = tab(i));
end loop;
I wrote the query using bind variables in the manner:
for i in 1 .. tab.count
loop
execute immediate 'insert into A(Col1, Col2) values (select constant_val, B.value from B where B.value = :1)' using tab(i);
end loop;
This compiles, but does not run ... error said is PLSQL statement not properly ended.
I also tried the option of giving constant_value in the using clause and replacing the same in query using a bind variable. It still doesnt work.
Is there someway by which i can squeeze in the constant value also. Can someone please advise me on this?
Thanks in advance,
Praveen G Sbut i was told that if i succeed
in reducing the hard parsing of queries .. i will get
better performance results .. Would i say too, at least for OLTP like systems
but if i cant or rather dont have to use it while
looping PLSQL tables and accessing data from other
tables using this data ... then what do we use it
for?? PL SQL is capable of bulk operations, so loop is less performant method to process data, however, if you can't do it bulk - for whatever reasons - do it in loop.
My remark was related mostly to dynamic sql, as shoblock already said, it seems to be no reason in your code to use dynamic sql, if you can use static...
What i not understand as well, why do you select a value from the table, if this value is already in your collection?
values (select constant_val, B.value from B where B.value = :1)' using tab(i);Best regards

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?

Using collections / Bind variables with a PL/SQL functio returning a query
I have this code, which is supposed to assign collection variables as column names
FOR i in 1 .. Collection_count -1
LOOP
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;
SELECT c002 into varholder FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;
vQuery:= vQuery || 'SUM(decode(label, ''Aware'', product_'|| i || ', ''Expert'', product_' || i || ', ''Proficient'', product_' || i || ', ''Advanced(Demo)'', product_' || i || ' )) as ';
vQuery:=vQuery || varholder || ', ' ;
END LOOP;
I've tried &P341_M1. , :P341_M1, ':P341_M1', varholder
When I try '&P341_M1' it returns the whole SUM(decode... line as the label
Basically Im having a hard time using bind variables with the PL/SQL returning a query...anybody?Ok so working through this problem more I have realized that the problem is using the for loop i as an index value
This will get a value:
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=2;
But this won't
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;
I'm in the for loop, and use the i variable in other places within this loop...Is there a reason why I can't compare seq_id to i?
My new code as follows:
FOR i in 1 .. Collection_count -1 --apex_application.g_f01.COUNT - 1
LOOP
varholder:=i;
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=2;

Using bind variables (in & out) with dynamic sql
I got a table that holds pl/sql code snippets to do validations on a set of data. what the code basically does is receiving a ID and returning a number of errors found.
To execute the code I use dynamic sql with two bind variables.
When the codes consists of a simpel query, it works like a charm, for example with this code:
BEGIN
SELECT COUNT (1)
INTO :1
FROM articles atl
WHERE ATL.CSE_ID = :2 AND cgp_id IS NULL;
END;however when I get to some more complex validations that need to do calculations or execute multiple queries, I'm running into trouble.
I've boiled the problem down into this:
DECLARE
counter NUMBER;
my_id NUMBER := 61;
BEGIN
EXECUTE IMMEDIATE ('
declare
some_var number;
begin
select 1 into some_var from dual
where :2 = 61;
:1 := :2;
end;
USING OUT counter, IN my_id;
DBMS_OUTPUT.put_line (counter || '-' || my_id);
END;this code doesn't really make any sense, but it's just to show you what the problem is. When I execute this code, I get the error
ORA-6537 OUT bind variable bound to an IN position
The error doesn't seem to make sense, :2 is the only IN bind variable, and it's only used in a where clause.
As soon as I remove that where clause , the code will work again (giving me 61-61, in case you liked to know).
Any idea whats going wrong? Am I just using the bind variables in a way you're not supposed to use them?
I'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bitCorrection. With execute immediate binding is by position, but binds do not need to be repeated. So my statement above is incorrect..
You need to bind it once only - but bind by position. And the bind must match how the bind variable is used.
If the bind variable never assigns a value in the code, bind as IN.
If the bind variable assigns a value in the code, bind as OUT.
If the bind variable assigns a value and is used a variable in any other statement in the code, bind as IN OUT.
E.g.
SQL> create or replace procedure FooProc is
2 cnt number;
3 id number := 61;

5 execute immediate

Using bind variable in dynamic where clause and concatenate with query
Hi,

ORA-01722: invalid number caused with SQL using bind variable
Hi,
Im am hoping that someone can help me resolve a problem thats only just services and is being experienced on quite a few clients.
our application uses C++ exes and makes OCI calls to the database.
what has happened in the last week or so, there has been quite a few invalid number errors being received on a prod server but strangly enough we cannot reproduct the error on our UAT system.
The sql is using bind variables and the information in the trace file shows that a number is being used for the bind variable, here is an extract from one trace file:
for some schemas, the bind variable value is some currupted value, i think:
oacdty=01 mxl=32(21) mxlc=00 mal=00 scl=00 pre=00
oacflg=03 fl2=1206001 frm=01 csi=178 siz=32 off=0
kxsbbbfp=9a8d62b8 bln=32 avl=03 flg=05
value="Â*d"
but on another schema, the value used is:
Bind#0
oacdty=01 mxl=32(32) mxlc=00 mal=00 scl=00 pre=00
oacflg=03 fl2=1206001 frm=01 csi=178 siz=32 off=0
kxsbbbfp=c5f92718 bln=32 avl=04 flg=05
value="2101"
however both produce invalid number errors.
I am relatively inexperienced as a DBA so would appreciate as much help as i can get.Could you post your sql statement that is being run.
Also post the query plan from your uat system and the one from your production system (They are likely to be different)
You can export the stats from your production system and run them in your uat system. If you do this, then the execution plans should be the same on both systems(dbms_stats) and if you have the same data you should run into the same problem on uat as in production.
The root cause of this type of problem is having a column in a table which holds values which are of different datatypes. Typically there is a condition in the where clause which indicates that for example only numeric columns should be retrieved from the column which holds multiple data types. However since the optimizer is free to rewrite the query any way it sees fit, (It does not necessarily execute in the order the sql statement is written) it does not filter this data first, and therefore you hit non-numeric data and run into the invalid number error.
You can use little techniques like using an inline view with rownum in the column list, to perform the first filter. This ensures that the inline view is executed on its own, rather than being merged (materialized) with the rest of the query.
A quick temporary solution is to use a comparison like to_char(column_name) = variable
Make sure your comparisons are correct and it doesn't negatively impact on performance of the query -

CyrylWhy are you using dynamic SQL statements? Why not just use something like this instead in your PL/SQL. I also replaced the leading // in your Xpath with just / since you start from the root node.

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@';

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'

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
Edited by: remaï on Apr 1, 2009 4:08 PMWhat 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.

ORA-06537 OUT bind variable bound to an IN position
Sir,
we have migrated our database from oracle 9i to 10g (Release 10.1.0.2.0)..
but while executing a procedure we are getting the following error
ORA-06537:OUT bind variable bound to an IN position
this same procedure is not throwing any error wen we connect the 9i database
we are giving two parameters for this procedure
in that second one is an IN OUT Parameter
another procedure which use the same parameters working properly in 10g and 9i.
we are using PowerBuilder 10 as front end
plz help me to get ride of this prob...You get that error even in 9i if the parameters to the procedure calls are not bound correctly. Check the powerbuilder application to make sure it is binding the parameter types correctly.

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,

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)
);
