In execution, I have this error: ora-01006: bind variable does not exist, after analysis, I found that the problem is with the settings: 5 and: 6, I do not understand that they have the same syntax

as variables bind 1,2,3 and 4.

Than you for any suggestion.

I hope that you realize that there are 13 variable bind in your sql, not 6?

Variables are related by mail. You cannot use the same variable to link twice, they will be 2 separate bind variable.

For example, you use: 1 three times, so you must provide three arguments, in this case, three times the same value.

IN construction in the clause WHERE of VO with bind variable
Hello
With the help of JDev 11.1.1.3.0.
I have a SQL according to VO following where clause ' WHERE some_nbr IN: inSomeNbrStr'

-variable binding inSomeNbrStr is of type String.
I'm assuming that this variable linking parameter to for example. "101, 102' or '(101, 102) ' before the execution of the query might work.
"However, I get ' ORA-01722: invalid number." Other than the substitution of executeQueryForCollection() and manipulate by program the

Hello

You "MOUNT" the binding variable to get the values separated by commas.

See this article (Search Using Comma-Separated bind string for the Variable in the list) on how to achieve this.

It has been developed over 10g. But I think it will hold good for 11g as well.

Problem with the selection list dynamic LOV using bind variables
I have the following SQL to fill a selection list:

Select d, ch from
(
Select ft. FAMT_NAME d, pi. R FAM_ID_T of FAMILY_TRA ft
Join the ck list
on ck.family = ft.famt_name and ck.newseq in (: NEWSEQ_QUERY_SQL)
)

Where NEWSEQ_QUERY_SQL is a part of the application that is defined by a calculation of page and essentially returns a list of values NEWSEQ based on some parameters of the user query. For example:

Select distinct (ck.newseq) in the ck list where rownum < 20

The query above works fine with SQL Developer and returns two columns needed (display_value, return_value)

However, it returns no line, when it is used to fill the LOV to a selection list.

If I replace the: NEWSEQ_QUERY_SQL with a list of NEWSEQ hard-coded, it works:

Select d, ch from to)
Select ft. FAMT_NAME d, pi. FAM_ID_T r
of FAMILY_TRA ft join checklist ck on (ck.family = ft.famt_name and ck.newseq in ('K0242900', 'K0217200'))
) ;

I can even replace: NEWSEQ_QUERY_SQL with hard-coded SQL and it works:

Select d, ch from
(
Select ft. FAMT_NAME d, pi. R FAM_ID_T of FAMILY_TRA ft
Join the ck list
on (ck.family = ft.famt_name and ck.newseq in (select ck.newseq from the list ck where rownum < 20))
)

But if there is a connection variable (: NEWSEQ_QUERY_SQL), it doesn't.

Selection lists are driving me crazy! They seem incredibly capricious.
Hello:

You cannot link a "sql statement" that bind the value you're trying to do.
P2_FAMILY_LIST must be the SQL statement you executed for the LOV. Something like
```
select d, r from

select ft.FAMT_NAME d, ft.FAM_ID_T r from FAMILY_TRA ft
join checklist ck
on (ck.family = ft.famt_name and ck.newseq in (select ck.newseq from checklist ck where rownum < 20))

Just talking about the top of my head, since I have not tried, but...

When you use the INTO clause, you are implying that you run in a 3GL environment, in this case, PL/SQL. But if it comes to PL/SQL, you have a BEGIN and END around all the instructions. You must have:
```
String sequnceDocumentId ="BEGIN SELECT snw_doc_type_map_id_seq.NEXTVAL INTO :1 FROM DUAL; END;" ;
```

Procedure with an unknown name or the amounts of the bind variable.
Hey gurus,

I hope someone out there can point me in the right direction.

I write a PL/SQL function that receives an unknown number of bind variables in the client.
I use Apex 1.1 earpiece to set up a model of RESTful resource for a x-www-formulaires-urlencoded body POSITION.

If the client publishes the following body: * "title = M. & fname = John & lname = Smith" * "

My PL/SQL procedure automatically receives the bind variables which is placed by the following:
: title: = "M";
: fname: = "John";
: lname: = 'Smith ';.

Now my limit is that the required design uses the metadata to define the structure of data of the end-user.
So in reality the body of MESSAGE I get more like this: * "M. = 120 & 121 = John & 122 = Smith" * "

So my PL/SQL procedure receives:
: 120: = "M";
: 121: = "John";
: 122: = 'Smith ';.

I can query the metadata tables to anticipate what bind variables can be present at the execution,
but this can change depending on the resource ID with the body of the MESSAGE at the time of the request.

My first attempt was to be a loop expected elements and run an EXECUTE IMMEDIATE likes:

for c_record_items in
(select field_id in the tfields where record_id =: id) loop
EXECUTE IMMEDIATE ' begin update_item ('|: field_id |', :'|| field_id |'); end;';
end loop;

But unfortunately the EXECUTE IMMEDIATE fails because the binding variable is not declared; It requires the USING clause.
Which I can't think I can code the amount or value in...

I started dabbling in the DBMS_SQL package but I still have to think of a way I can fix this problem.

There are experts out there who can direct me in the right direction?
Very much appreciated.

I have a lot of procedures where I accumulate the number of bind variables.

My approach has been to load each variable binding in an associative array and maintain a counter of the number of bind variables.

Finally, there is a great if then elsif endif block which is actually
```
if v_binds = 0
then
     execute immediate ;
elsif v_binds = 1
then
     execute immediate  using bind_array(1);
elsif v_binds = 2
     execute immediate  using bind_array(1), bind_array(2);
elsif ...
end if;
```

Estimate of poor cardinality using Bind Variables

Hi I'm using the 11.2.0.4.0 Oracle version. I have a query that is underway for the plan of the poor execution by the estimate of poor cardinality for two tables (I've extracted and published this part only) as I mentioned below, the individual conditions for which the estimate goes bad and moving entire query execution path.

These are for two tables and currently we use BIND variable for them in our code, and I notice, its best estimate gives with literals. I need to know how to handle this scenario that I need this query to execute for all types of volumes. Is there something I can do without changing the code, as it works well for most of the execution? In the current scenario of the main query that uses those below tables providing a plan (index + nested loop) that works very well for small volume, but running for 10 hr + for large volume as ideally its going to the same regime.
And Yes, most time that this request will be hit for small volume, but killing some appearance of large volume presents the performance of the queries.

Here are the values of the variable binding.

B1 VARIABLE VARCHAR2 (32);
B2 VARIABLE VARCHAR2 (32);
B3 VARIABLE NUMBER;
B4 VARIABLE VARCHAR2 (32);
B7 VARIABLE VARCHAR2 (32);

EXEC: B2: = NULL;

In fact for literals, I did not find any section of the predicate after running the sql code with activation "set autotrace traceonly explain."

The main problem is with another large query whose cardinality is underestimated due to the presence of these table (table1, table2) with the above mentioned clause, and the query is for the analysis of index + nested with values of Bind loops and take 10 hr +, whereas with literals, its completion in ~ 8minutes with FTS + Hash Join.

Your real problem is that you try to have just a single SQL query handle all POSSIBLE thanks to the use of embedded FILTERS ' either / or ' filters in the WHERE clause. You want only a select this OPTION to run whatever filters have been selected at run time by the user or the application using it. And it would never work. You really need to SELECT different queries for different combinations of filter conditions.

Why? Think for a minute. How Oracle works internally? A SQL SELECT query gets analyzed and an execution plan is produced which is stored in the library cache and gets REUSED on all subsequent executions of this query - except in certain cases where there may exist several plans run through several cursors of the child. So with only SELECT a query you only AN execution plan in the library cache, to be used by all THE executions of this query, regardless of the value of your run-time binding variables.

Lets put another way - each library cache execution plan is associated with a SQL statement. If you want a DIFFERENT execution plan then you need run a DIFFERENT SQL statement. That's how you get a different execution plan - by running a different SQL statement. Running the SAME SQL query generally you will get the SAME execution plan every time.

In addition, because of the "either / or" filters that you use you will end up generally with a full Table Scan on each of the referenced tables. Why? Given that the optimizer must produce an implementation plan that manages all possible contingencies for all values of possible bind variables in the SELECT. If the optimizer should choose to use any index based on one of these "either / or" filters then it would only help performance when real value was provided, but it would be really bad if a NULL value was supplied. If the optimizer ends up ignoring the index because they are not always optimal for all possible input values and instead chose a plan that is "good enough" for all input values possible. That means that it will use a scanning Table full.

I hope you can see that it is precisely what is happening for you with your query. You select this OPTION to manage the different combinations of filter, which leads to the execution plan only one, which leads to scans full Table on the referenced tables in these ' either / or ' filters.

The solution? Build queries SELECT DIFFERENT when input values are NULL. How you do that? Read this article to ask Tom that tells you:

http://www.Oracle.com/technetwork/issue-archive/2009/09-Jul/o49asktom-090487.html

To sum up - when you have real value for a bind variable 'bind_var1' add the following filter to your CHOICE:

AND column_name1 =: bind_var1

When the binding variable is NULL, add the filter according to your CHOICE:

AND (1 = 1 OR: bind_var1 IS NULL)

Now, you'll have 2 queries SELECT must be performed, which have exactly the same number of variables in the same order bind, which is important. When you then run one of these variations, Oracle can analyze and optimize each one SEPARATELY, with a single execution by the SELECT query plan.

When you provide a real value, the filter is a normal 'column = value' that the optimizer can use all indexes on this column, because NULL values are not referenced.

When there is no real value, the optimizer will analyze the '1 = 1 GOLD' and realize that "1 = 1" is set to TRUE and GOLD, it is quite TRUE regardless because the binding variable is null or not. This means that the optimizer will actually REMOVE this filter, because it filters nothing because it is always TRUE. You will end up with an operating plan based on the other filters in the query, which is what you want because you have no filter on this column.

What is it - producing distinct SELECT queries to determine if you have a real value to filter or not you end up with DIFFERENT execution plans for each of them, and each of them is OPTIMAL for this particular set of filters. Now you get good performance for each variation of the performance of the SELECTION, rather than sometimes good and sometimes very bad when using SELECT only one. It is impossible to try to get multiple shots of execution 'optimal' out of a SELECT query. That's why you get mediocre performance under different bound the values of the variables.

R12 Extension with bind variables-how VO EO

Hello
I extended an APInvDistAllVO view object by adding two fields which are functions. Basically, in the invoice approval screen, I want to add two fields where the distribution of the invoice is shown.
the SQL contained in jdeveloper when you extend the VO object is different from the query, what I see in the invoice approval page by clicking on the APInvDistAllVO link. There are two bind variable: 1 = invoice_id and: 2 = line_number being added dynamically.
After the extension of the view object, the invoice distribution line is displayed as no record found. In my opinion, it is due to not having bind variables does not correct parameters being passed, and under this point of view object is an object depending on the invoice header record.
Will be very grateful if someone can provide the way forward in dealing with this situation.

Bind Variables out of use

I don't know where to post this, please point me in the right direction if necessary. It seems that binds the variables in the order that they appear in the SQL statement works very well, but bind them down causes the statement to be poorly executed. Here is the result on my machine, Win 7 Pro, JDK 1.7.0_21 against Oracle 11.2.0.3 on Linux 64.

Create table test
Insertion of temporary data
Display all data
10 50 Red
20 40 Green
30 30 Blue
10 40 Orange
20 50 yellow
70 rose 10
Selection of A = 10 and B = 50 in the order
10 50 Red
Selection in the reverse of A = 10 and B = 50
Table of drop test

Here's the code that produced these results. The difference between the declarations of the first and the second selection is simply the order, that the variables are related. Am I doing this wrong?

I don't know where to post this, please point me in the right direction if necessary. It seems that binds the variables in the order that they appear in the SQL statement works very well, but bind them down causes the statement to be poorly executed. Here is the result on my machine, Win 7 Pro, JDK 1.7.0_21 against Oracle 11.2.0.3 on Linux 64.
>
Although what do you expect to link which includes a colon in the name?
```
cs.setInt(":a", 10);
```
And the code like this
```
cs.setInt("a", 10);
```
is NOT supported. You can not bind by name using the setXXX methods.

Change your code to use syntax supported, and you shouldn't have a problem.
```
cs = c.prepareCall("select * from eric_example where a = :1 and b = :2");
cs.setInt(1, 10);
cs.setInt(2, 50);
```

>
Binding parameters named

Binding by name is not supported when using the setXXX methods. In certain circumstances, previous versions of the Oracle JDBC drivers have allowed binding variables name declaration when using the setXXX methods. In the following statement, the variable named EmpId is linked to the whole 314159.

P = conn.prepareStatement PreparedStatement
("" SELECT name FROM emp WHERE id =: EmpId "");
p.setInt (1, 314159);

This ability to set by name using the setXXX methods is not part of the specification, JDBC and Oracle does not support. JDBC drivers can throw an SQLException exception or produce unexpected results. From JDBC Oracle Database 10 g drivers, connection by name is supported by using the setXXXAtName methods.
>
You can use one of these 'previous versions' driver which seem to confirm the connection by name but these links are NOT supported, so you should not try to use them.

There is no work around. Replace the names of variables bind with an exclamation mark.

Performance tests: bind variables
When you write a SQL for the application, I want to do some performance testing of SQL before providing to JAVA developers. I understand that I need to test using bind variables, can someone guide me how do? What are the best tools out there to achieve? Please provide some guidance. Thank you!
Rinne says:
I read more about bind variable and I can test the use of bind variables. I understand that testing SQL using bind variables is a closer representation of the real world. Even when queries have large tables, the performance would be similar if I run the query using literals twice (to avoid hard analysis) compared to tests with bind variables? I am trying to understand more thoroughly the need for tests with bind variables. Why we take more time than the other? Thank you!

The main thing is that the opimizer will / can do if bind variables different optimization techniques are used or not.
There are two contradictory effects its regarding the binding settings.

Effect 1: Reuse of cursor
If the same is done again and again and again. Maybe different sessions. Then using binding settings is essential. Why? Because the same cursor can be reused, which saves a lot of time for analysis. This occurs mainly in OLTP systems. The idea behind this is that to do the same action, just for a different ID (ID in order for example) will result in an identical implementation plan.

The result: Faster analysis time and less consumption of memory, because the same cursor can be resused between different sessions.

Effect 2: Correct assumptions

According to a filter expression, some using the value of the OBC will make an assumption based on statistical data the number of rows is returned because of this expression and the value.
Speculation between a literal value and a bound value may be different. In many cases exist technical opimization (bind peeking etc.) to the same literal conjecture binded proposal.

But there are exceptions, for example a condition such as the following will result in different estimates
```
column between 10 and 20
```
```
column between :P1 and :P2
```
There are as well other effects.

Result: The CBO can make assumptions better if literals. But most of the cases the proposal is identical.

Conclusion: Literal values are useful if you do large queries where the output size depends strongly on the parameters provided, and where you run that very few of these (OLAP) queries.
Binding settings are usfull when the same execution (OLTP) need a grand plan number of queries.

bind variables and dynamic sql

Hi all

Here's my situation:

I have a query with 2 bind variable: the FROM clause also uses a variable binding!

PROCEDURE describe_columns(p_curr_tablename VARCHAR(50), p_curr_intentseq NUMBER)
   IS
      l_cur     INTEGER;
      l_query   VARCHAR (100);
   BEGIN
      l_query :=
         'select * from :table_name where ibmsnap_intentseq = :sequencenr';
      l_cur := DBMS_SQL.OPEN_CURSOR;
      DBMS_OUTPUT.PUT_LINE (p_curr_tablename);
      DBMS_OUTPUT.PUT_LINE (p_curr_intentseq);
      DBMS_OUTPUT.PUT_LINE (l_query);
      DBMS_SQL.PARSE (l_cur, l_query, DBMS_SQL.V7);
      DBMS_SQL.bind_variable (l_cur, ':table_name', p_curr_tablename);
      DBMS_SQL.bind_variable (l_cur, ':sequencenr', p_curr_intentseq);
      DBMS_SQL.DESCRIBE_COLUMNS (l_cur, g_count, g_desc_tab);
      DBMS_SQL.CLOSE_CURSOR (l_cur);
   EXCEPTION
      WHEN OTHERS
      THEN
         DBMS_OUTPUT.put_line ('DF-EXCEPTION: ' || SQLERRM);
         DBMS_OUTPUT.put_line (
            'DF-EXCEPTION: ' || DBMS_UTILITY.FORMAT_ERROR_BACKTRACE
         );

         IF DBMS_SQL.IS_OPEN (l_cur)
         THEN
            DBMS_SQL.CLOSE_CURSOR (l_cur);
         END IF;
   --         RAISE;
   END;

and the output is:

CD_B136V4_NEW
16
 select * from :table_name where ibmsnap_intentseq = :intentseq
DF-EXCEPTION: ORA-00903: invalid table name
DF-EXCEPTION: ORA-06512: in "SYS.DBMS_SYS_SQL", line 906

So is the problem that I want to use a variable binding for the name of the table?

I'd appreciate any help!
Thank you!

Identifiers cannot be used as variable bind - never. Identifiers must be "hard-coded".
in the query.

I can't put in a link for "emp" variable because I can't use a string
constant for emp.

The reason is quite simple - a bind variable query is parsed and optimized once
variables are evaluated before linking. If I could code:

Select * from: bind_x

the optimzer would not have an idea of what will come with, security (access rights)
could be evaluated and so on. We could not develop a plan for this query - not
enough information. Therefore, no variable bind for identifiers.

Report using Bind Variables
Hey everybody,

I have a little trouble to create a report. I need the FROM part of the code in order to use bind variables. I came up with this piece of code below, but im getting the following error:

Failed to parse the SQL query:
ORA-06550: line 1, column 8:
PLS-00103: encountered the symbol "" when expecting one of the following values:

begin function package pragma procedure subtype type use
form
current cursor
The symbol "" was ignored.
ORA-06550: line 2, column 24:

PLS-00103: encountered the symbol "" when expecting one of the following values:

begin function package pragma procedure subtype type use
form
course

Where can I see im wrong?

Thanks in advance,
-N.S.N.O.

Code
DECLARE
x VARCHAR2 (4000);
BEGIN
x : = x || "select *";
x : = x || "from";
x : = x || : p13_schema;
x : = x || '.ddl_log @';
x : = x || : p13_db_name;
x : = x || ' _DBAAPEX. TNTEWW. COM';
RETURN (x);
END;
AHA, but when you have changed the source, have you also changed the Type (from "SQL query" to "SQL Query-PL/SQL function return SQL Query")?
And clicked on "use generic names (analysis of query runtime only) column" option below the source code?

Not able to bind variable Fusion Dev Guide Document clearly as follows.

Dear all,

I have a problem following the merger Developer Guide specifically items link below

http://docs.Oracle.com/CD/E23943_01/Web.1111/b31974/bcquerying.htm#CHDDHIHJc

1.     (Request begins and application module is acquired)
2.  Call setWhereClause(null) to clear WHERE clause
3.  Call setWhereClauseParam(null) to clear the WHERE clause bind variables
4.  Call setWhereClause() that references n bind variables
5.  Calling setWhereClauseParam() to set the n values for those n bind variables
6.  Calling executeQuery()
7.  (Application module is released)

I actually wanted to erase all my bind variables including the binding variable that I put in the request.

SELECT Persons.PERSON_ID, 
       Persons.PRINCIPAL_NAME, 
       Persons.TITLE, 
       Persons.FIRST_NAME, 
       Persons.LAST_NAME, 
       Persons.PERSON_TYPE_CODE, 
       Persons.SUPPLIER_ID, 
       Persons.PROVISIONED_FLAG, 
       Persons.PRIMARY_ADDRESS_ID, 
       Persons.REGISTERED_DATE, 
       Persons.MEMBERSHIP_ID, 
       Persons.EMAIL, 
       Persons.CONFIRMED_EMAIL, 
FROM PERSONS Persons
WHERE Persons.PERSON_TYPE_CODE = :PERSON_TYPE_CODE_PARAM

Step 3 is where I'm having a problem. I can't find in the API on setWhereClauseParam (null) which accepts the string but
It has only setWhereClauseParam (int, String)

Not sure if I'm running on a bug in the documentation.

JDEV 11G PS5

That look like a bug in documentation for me.
The correct method to call is

setWhereClauseParams(null); //note the 's' in Params!

Interactive report Bind variable not working do not?
Hello

I'm new to APEX and try to find how to use APEX of interactive reports with bind variables. So, I created one with the following query:

SELECT i1.if_bic_code, b.bicname, count (*) NTC
OF IF_DATA i1, bic b
WHERE i1.if_bic_code = b.biccode (+)
AND i1.insert_date BETWEEN: P40_X1 AND: P40_X2
I1.if_bic_code GROUP, b.bicname

The report is supposed to show a number of comments by the bic_code (= bicname) of the IF_DATA table for the specified period.

These 2 bind variables are actually 2 Articles in the same region, with the help of a DatePicker for them. They have no initial values. Thus, the report displays initially no record. After either by using the date picker or manually enter values in these 2 points and pressing go button doesn't always display no line. Am I missing something here? It seems that the query again to the database, or the bind variables do not take the values entered for them.

TIA
Hello

If you are the Go button that appears on the interactive report action bar, you must add in page elements names that must be saved when you do this, as the page itself is not subject to (which is the normal action that saves your dates).

To do this, change the attributes of the report and go to the bottom of the page. You should see a section attributes advanced with a parameter "Page to go". In this, enter:
```
P40_X1,P40_X2
```
-C' is a list separated by commas to names of page elements that you saved when you click the Go button

Andy

on the ora-01006: there is no bind variable
