ORA-01006: there is no bind variable

Hello

I'm trying to shoot an insert that inserts data into a table from another table based on certain conditions.
But I get this error.

declare
v_c1 varchar2(10):='a1';
date_c2 varchar2(15):='12-aug-2012';
begin
strquery:='insert into tab1 select from tab2 where tab2.c1='':x'' and tab2.c2='':y''';
execute immediate strquery using v_c1,date_c2; ------------BIND VARIABLE date_c2 does not exist
end;

Review your dynamic sql code:

SQL> set serveroutput on
SQL> exec dbms_output.put_line('insert into tab1 select from tab2 where tab2.c1='':x'' and tab2.c2='':y''');
insert into tab1 select from tab2 where tab2.c1=':x' and tab2.c2=':y'

PL/SQL procedure successfully completed.

SQL>

Can't you see you just bind variables? All I see are strings ": X"and": there '." Change:

 strquery:='insert into tab1 select from tab2 where tab2.c1='':x'' and tab2.c2='':y''';

strQuery: ='insert into select tab1 tab2 where tab2.c1 =: x and tab2.c2 =: y';

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.

Thank you
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;" ;
```

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.

Hi AJ

He worked after changing the style of bind.

Thank you very much.

Oracle.ManagedDataAccess gives ORA-01006 if there is bind variables in the comments, but only on the lines.

When I go from ODP.NET to the ODP.NET managed some of my questions begins to throw errors missing bind variable.
I reproduced with a simple example that uses a variable called liaison: unitName
It's the example SQL:
SELECT
: unitName
Of
DOUBLE
Now, if I add a comment at the beginning of the SQL like this:
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
It works, but if I have a variable binding in a comment that is located on a number of the 'same' line, I get ORA-01006:
This causes the error:
-First line comment
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
Kind regards
-Tommy

I was able to reproduce this problem. I filed Bug 19433348 on your behalf.

The circumstances in which the bug occurs are fairly easy to get around.

(1) remove the colon in the second commented line.

(2) add a space between the '\n' and ' - '.

If you are one of those things, you won't encounter the bug behavior.

is there an order to the bind variable in v$ SQLTEXT_WITH_NEWLINES?

so as you can see from the output of the order of the table v$ and order, I entered bind variables are reversed. Is this always the case or it is not consistent?

I guess it's just a matter of curiosity, right? All that matters is to connect the variable ends up in a good position. Anyway, as far as I KNOW, Oracle creates a bind variable in the order, and therefore depends on the analysis from left to right or from right to left. And we don't know how to change the order in the different versions of Oracle.

Bind Variables and using the keyword

In my dynamic SQL, I use the same variable in several places in my query. Is there a way to avoid rewriting the same value multiple times in the list of arguments to bind? It is something like that - only pseudo code.

DECLARE
tSQL VARCHAR2(99)
pVal INT := 2;

BEGIN
tSQL := 
           'SELECT * ' ||
           '  FROM dual ' ||
           ' WHERE col1 =: iVal ' ||
           '   AND col2 IN (SELECT col2 ' ||
           '                  FROM dual  ' ||
           '                 WHERE col1 =: iVal) ' ||
           ' UNION ' ||
           ' SELECT * ' ||
           '   FROM dual ' ||
           '  WHERE col1 =: iVal';

EXECUTE IMMEDIATE tSQL 
USING pVal, pVal, pVal;  -- Is there a way to avoid having to rewrite the same bind variable argument three times since the value is the same?

END;

Is there a way to avoid having to rewrite the same argument three times bind variable as the value is the same?

Etbin wrote:
http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/dynamic.htm#BHCHIHEJ says:
Placeholders are associated with bind variable in the USING clause of position, and not by name.

Concerning

Etbin

The exception to this rule is if the SQL statement is an anonymous block or a call statement. In this case, the repetition of the names of the placeholder is significant.

http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/dynamic.htm#CHDFHEAG

For example, the following will fail with ORA-01008: not all variables

declare
 v_cnt number;
begin
  execute immediate 'select count(*) from dual where 1 = :B1 and 2 > :B1'
  into v_cnt using 1;
  dbms_output.put_line(v_cnt);
end;

However, the following will succeed because the SQL code is in fact an anonymous block:

begin
  execute immediate 'declare
                       v_cnt number;
                     begin
                       select count(*)
                       into v_cnt
                       from dual
                       where 1 = :B1 and 2 > :B1;
                       dbms_output.put_line(v_cnt);
                     end;'
  using 1;
end;

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);
B5 VARIABLE NUMBER;

EXEC: B2: = NULL;
EXEC: B3: = 0;

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.

Estimates of cardinality for index range scan with bind variables

Oracle 11.2.0.4

I am struggling to explain that the cardinality estimates for a scan of the index systematic range when using the bind variable.

Consider the following query:

SELECT /*+ INDEX(t1) */ *
FROM   t1
WHERE  source_id <= ?;

Cardinalities for the INDEX RANGE SCAN and ACCESS of the TABLE are the same for different literal predicates, for example, source_id < = 5:

------------------------------------------------------------------------------------
| Id  | Operation                   | Name | Rows  | Bytes | Cost (%CPU)| Time     |
------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT            |      |    50 |   350 |    12   (0)| 00:00:01 |
|   1 |  TABLE ACCESS BY INDEX ROWID| T1   |    50 |   350 |    12   (0)| 00:00:01 |
|*  2 |   INDEX RANGE SCAN          | IX1  |    50 |       |     2   (0)| 00:00:01 |
------------------------------------------------------------------------------------

Predicate Information (identified by operation id):
---------------------------------------------------

   2 - access("SOURCE_ID"<=5)

If a variable binding is used instead of a literal, the overall selectivity is 5%. However, why the optimizer based on CSSTidy gives a cardinality estimated 11 for the scan of the index systematic range? As with the predicates literal, surely the cardinalities of the index range scan and access table should be the same?

------------------------------------------------------------------------------------
| Id  | Operation                   | Name | Rows  | Bytes | Cost (%CPU)| Time     |
------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT            |      |    50 |   350 |     5   (0)| 00:00:01 |
|   1 |  TABLE ACCESS BY INDEX ROWID| T1   |    50 |   350 |     5   (0)| 00:00:01 |
|*  2 |   INDEX RANGE SCAN          | IX1  |    11 |       |     2   (0)| 00:00:01 |
------------------------------------------------------------------------------------

Predicate Information (identified by operation id):
---------------------------------------------------

   2 - access("SOURCE_ID"<=TO_NUMBER(:A))

Unit test code:

CREATE TABLE t1
( id NUMBER
, source_id NUMBER
);

CREATE INDEX ix1 ON t1 (source_id);

INSERT INTO t1
SELECT level
     , ora_hash(level,99)+1
FROM   dual
CONNECT BY level <= 1000;

exec DBMS_STATS.GATHER_TABLE_STATS(user,'T1')

EXPLAIN PLAN FOR
SELECT /*+ INDEX(t1) */ *
FROM   t1
WHERE  source_id <= 5;
SELECT * FROM TABLE(dbms_xplan.display);

EXPLAIN PLAN FOR
SELECT /*+ INDEX(t1) */ *
FROM   t1
WHERE  source_id <= :a;
SELECT * FROM TABLE(dbms_xplan.display);

There are various places where the optimizer uses an assumption, and lie unpeekable (and of Villa "unknowable value") introduced guess.

For unpeekable binds the conjecture for column<= {unknown}="" is="" 5%="" for="" table="" access="" (hence="" 50="" rows="" out="" of="" 1,000),="" but="" it's="" 0.009="" for="" index_column=""><= {unknown},="" which="" means="" i="" was="" expecting="" to="" see="" 9="" as="" the="" row="" estimate="" on="" the="" index="" range="">

I just ran some quick tests, and EXPLAIN the PLAN seems to just use 0.011 selectivity in this case (in different versions of Oracle) although if we do the bind variable unpeekable at run time (and sample dynamic block etc.) optimization for execution is 0.009%.

Update: and this is a very old reference to the 0.009 (and 0.0045 for ' between the ' when it is applied to a clue: cost based Oracle - access Chapter 4 single B-tree )

Bind Variables on the view objects child definition

JDeveloper 12 c
I have an interesting question. I have a view (AisWebModulePrivsVO) object that uses a bindvariable hardcoded in the view object.
SELECT * FROM SYS. DBA_ROLE_PRIVS where DEALER =: bvUserName
If I put this in the request module I can programmatically set the variable binding (view object contains the getter/setter for the binding variable).
AisWebModulePrivsVOImpl voTest = am.getAisWebModulePrivsVI ();
voTest.setbvUserName ("ARAWLS");
voTest.executeQuery ();
System.out.println ("test reports:" + voTest.getRowCount ());
and get the correct number of records based on return on the user and database roles. If it works.
What does NOT work, it is when this display object is a recording of 'the child' to another display object (as specified by a link between the two and by setting the object from a point of view as one child of the other in the module of the application).
AppModule looks like this:
CgRefCodesVO
AisWebModulePrivsVO
In this case, I have a view called cgRefCodeVO parent object. There is a link between this and the AisWebModulePrivsVO. The relationship works.
AISMenuAppModuleImpl m = ADFUtils.getApplicationModuleForDataControl (appMod) (AISMenuAppModuleImpl);
CgRefCodesVOImpl cgRefVO = am.getCgRefCodes1 ();
AisWebModulePrivsVOImpl modsVO = am.getAisWebModulePrivs1 ();
modsVO.setbvDBUserName ("ARAWLS"); This doesn't seem to work here...
cgRefVO.executeQuery ();
All lines rs = cgRefVO.getRowSet ();
RS. Reset();
While (rs.hasNext ()) {}
CgRefCodesVORowImpl CgRefRow = rs.next ((CgRefCodesVORowImpl));
System.out.println ("RvLowValue:" + CgRefRow.getAttribute ("RvLowValue"));
RowIterator aisModulesRowIter = CgRefRow.getAisWebModulePrivs ();
System.out.println ("number of children:" + aisModulesRowIter.getRowCount ());
}
The code compiles and runs. She translates: "County of the child: 0" for each row returned by the
I also tried:
VM VariableValueManager = modsVO.ensureVariableManager ();
vm.setVariableValue ("bvDBUserName", "ARAWLS");
And:
modsVO.setNamedWhereClauseParam ("bvDBUserName", "ARAWLS");
and (of https://community.oracle.com/message/2746551#2746551 ( )
@Override
protected void executeQueryForCollection (Object, object, Object [] object2, int i) {}
I coded everything hard to see if it would work.
setNamedWhereClauseParam ("bvDBUserName", "ARAWLS");
super.executeQueryForCollection (object, object2, i);
}
and from there, I changed around the order to execute the objects in view. https://community.oracle.com/message/10632314#10632314
How can I set the variable binding in the object view child?
Thank you
Stuart

It is an interesting example how ADF works up to a certain point... then you need to start to make cuts to modify its behavior as you wish.

I decided that it was just easier to delete 'the child' parent (in the app module) and create a view of criteria on this subject for what would basically query the records to get the same results, like a child.

Perhaps not as elegant, but so much easier.

Thanks for your help.

Bind variables in SPARQL WLS jena queries

Hi all
We read about the possibilities of support of jena to bind the variables in the documentation (http://docs.oracle.com/cd/E11882_01/appdev.112/e25609/sem_jena.htm#RDFRM248). The problem has been addressed in the next section on 14 June 2014 (Bind Variables in SPARQL queries). However, we are facing other problems.
We use:
* WLS 12.1.3.0.0
* adapter jena 2.11.1.
* Joseki 3.4.4.
* ARQ 2.9.2.
We try to run the following query on the stop of joseki.
PREFIX foaf: http://xmlns.com/FOAF/0.1/ >
PREFIX vcard: http://www.w3.org/2001/vCard-RDF/3.0# >
PREFIX ORACLE_SEM_FS_NS: http://Oracle.com/Semtech#no_fall_back, ODS = 6, ALLOW_DUP = T, s2s >
PREFIX ORACLE_SEM_HT_NS: http://Oracle.com/Semtech#monitor >
PREFIX ORACLE_SEM_UEAP_NS: http://Oracle.com/Semtech#f$ RDFVID % 20 to (?) >
PREFIX ORACLE_SEM_UEPJ_NS: http://Oracle.com/Semtech#f $RDFVID >
PREFIX ORACLE_SEM_UEBV_NS: http://Oracle.com/Semtech#1264839720472151591 >
SELECT? f? g
WHERE
{graph? g {? vcard:N p? vn.}}
? VN vcard:Family? f.
? FOAF:title p 'Sen'.}
}
However, the result that we get back does not use the variable binding. It returns the entire list without UEAP/UEPJ/UEBV.
Is there something that I missed in the documentation or should I define some variables for the use of bind variables?
Kind regards
Max

Hi Max,.

Can you please define the following JVM property to the WLS and restart the middle range?

-Doracle.spatial.rdf.client.jena.allowAP = true

This configuration is only necessary when running a variable binding based SPARQL query from a web service endpoint.

Let me know if this can help,

Bind variables and dates

I am writing a process to delete records based on dates.

Here is the chart:

Column name	Data type	Nullable	Default	Primary key
ID	NUMBER	NO.	-	1
CT_NAME	VARCHAR2 (100)	Yes	-	-
CT_CATEGORY	VARCHAR2 (100)	Yes	-	-
BASE_PTS	NUMBER	Yes	-	-
PROD_PTS	NUMBER	Yes	-	-
REF_PTS	NUMBER	Yes	-	-
START_DATE	DATE	Yes	-	-
END_DATE	DATE	Yes	-	-
CREATED_ON	DATE	Yes	-	-
CREATED_BY	VARCHAR2 (50)	Yes	-	-
UPDATED_ON	DATE	Yes	-	-
UPDATED_BY	VARCHAR2 (50)	Yes	-	-

start_date and end_date are the fields of date key.

The query will remove the dates with specific start and end dates. The question I have, is that I get a ORA-01858: a non-digit character was found here where was waiting for a digital error while the query is running.

remove from ct_point_values

where start_date =: P4_START_DATE_V

and end_date =: P4_END_DATE_V

If I run the query in the sql window, no problem:

remove from ct_point_values

where start_date =' 01 / 01/2014 '

and end_date = 31 December 2014"

Find the query with the works of values hard-coded. Links to fail. I tried casting and to_char to_date variations with no luck.

One thing that I notice, is that when I go to enter my bind variables in the sql workshop, the fields are pre-populated with this:

1 & amp; #x2F 1 & amp; #x2F; 2014

12 & amp; #x2F 31 & amp; #x2F; 2014

01/01/2014 and 31/12/2014. I found that the only element relates to this suggests that this is a possible bug:

SQL Bind Variables workshop - Date issues

Any thoughts on how to address this issue, or is it really a bug?

I run on Apex 4.2, 11g.

Thank you!

Hello

I guess that these dates come from elements on the page to which the user can select a range of dates.

These fields have a custom format mask?

What seems to be the case for me, is that these fields have an explicit format mask (for example: DD/MM/YYYY) but the default database/session format mask is something different (e.g. DD-MON-YYYY).

I suppose also that the issue in the SQL workshop isn't something related.

default values for VO bind variable

Hi all
I have a VO with bind variable year and month
These variables have values as:

year:
cannot import
DF = new SimpleDateFormat("yyyy")
DF.format (ADF. CurrentDate)
month:
cannot import
DF = new SimpleDateFormat ("MM")
DF.format (ADF. CurrentDate)
I have a table in my application this VO-based. I added these two variables as a counter entry number and a command button (ExecuteWithParams)
The table is delivered with these variables dafult (2014 & 2). That's ok. Problem is that default values are not in the number of counters during the loading of the page.
When I enter the new values (2014 & 1) and click the button, the new values to come and there is no problem...
JDev version is 11.1.2.4
Thank you...

I find the solution as:

In the pageDefinition file > binaries > ExecuteWithParams1_p_year > DefaultValue value as value: #{MyBean.year}

ORA-01006: there is no bind variable
