Comma Separated Values in Bind Variable

Hello

I'm on Oracle9i Enterprise Edition Release 9.2.0.6.0 - Production.I use in query

select * from employees where first_name in ('Ajay','Ajay5')

It gives me two rows as it should. Now, I want to pass these values as a bind variable.

select * from employees where first_name in :1

Now when I run the query and make its contribution as a ('Ajay', 'Ajay5'). It gives me no line.

Is their any way to do this. Let me know if you have any questions

Thank you
AJ

The research of a column with comma separated values with ora-text
I use the Oracle 11 g 2 XE and Oracle Text to a web search engine.

I've now created and text indexed a CLOB keywords column that contains words separated by spaces. This allowed me to expand the search, as Oracle Text returns the rows that have one or more keywords that are stored in this column. The contents of the column are visible to the user and serves to 'expand' the search. This does not work as expected.

But now I need support several words or even sentences. With the current configuration, Oracle Text will only search for each keyword. How should I store the phrases and configure Oracle text so that it will search entire sentences (exact match is better, but the partial match is fine too)?

Example of content column of two lines (values separated semicolon):
"Hello, Hello; y at - it anyone out there? Nope; »
"the just; basic facts; »
I found a similar question: looking for a column with values separated by commas, except that I need a solution for Oracle 11 g with it's freetext search.

Possible solutions:
1st solution: I thought to redraw the DB as follows. I would like to make a new array of keywords (pkID NUMBER, nonUniqueID NUMBER, singlePhrase VARCHAR2 (100 BYTE)). And I want to change the column previous keyword to KeywordNonUniqueID, holding the ID (instead of a list of values). At the time of the research I had INNER JOIN with the new keyword table. The problem with this solution is that I will get several lines containing the same data except for the sentence. I guess this will destroy the ranking?

2nd solution: is it possible to store sentences as an XML in the column key of origin and somehow say Oracle text to search for in the XML?

3rd solution: separate individual phrases with spaces, but replace the spaces in sentences with the underscore or something (making a single word). If a phrase "why Hello there, Johnny!" is saved as "Why_hello_there, _Johnny!

4th solution?:

Note that, generally, there is a lot of sentences (less than 100), nor that they will be long (one sentence will be up to 5 words).

Also note that I am currently using CONTAINS, and needs some of its operators, to my full-text searches.
When you talk about "phrase", do you mean "a list of words separated by a comma other sentences?

Isn't that the definition of "sentence" used by Oracle Text, where it simply means "a list of words in the order defined."

If I understand your requirement, you want to have data such as:

"aa bb cc dd".
"aa ee dd ff.

and give priority to the first on the second if someone looking for "dd".

First, to conduct research in the comma separated list, you should look for in a section. You can either explicitly define sections of field such as
AA bb cc dd
Or you can use the PHRASE special section and set the sentence delimiters correctly. This is done with the attribute BASIC_LEXER punctuation

Then you have the number you want to find only words where they are the only words in the section. That's the same problem, I address in the last post of this forum entry:
Contains: match exactly

Our solution will be substantially the same, some surrounding text with special markers, and then prioritize a phrase search with these special markers each side of the word.
We need to do a treatment some additional, although, as we need to surround each "sentence" (in your terminology) with special markers. I did it by surrounding the text with "XX1"... Condition2"then by replacing every comma with"Condition2, XX1"as part of a MULTI_COLUMN_DATASTORE:
```
drop table names;
create table names (id number primary key, text varchar2(50));

insert into names values( 1, 'just and kind, kind and loving' );
insert into names values( 2, 'just, kind' );

exec ctx_ddl.drop_preference  ( 'mylex' )
exec ctx_ddl.create_preference( 'mylex', 'BASIC_LEXER' )
exec ctx_ddl.set_attribute    ( 'mylex', 'PUNCTUATIONS', ',' )

exec ctx_ddl.drop_preference  ( 'mcds' )
exec ctx_ddl.create_preference( 'mcds',  'MULTI_COLUMN_DATASTORE' )
exec ctx_ddl.set_attribute    ( 'mcds', 'COLUMNS', '''XX1 ''||replace(text, '','',''XX2, XX1'')||'' XX2''' )

exec ctx_ddl.drop_preference  ( 'mywl' )
exec ctx_ddl.create_preference( 'mywl', 'BASIC_WORDLIST' )
exec ctx_ddl.set_attribute    ( 'mywl', 'SUBSTRING_INDEX', 'YES' )

create index namesindex on names(text)
indextype is ctxsys.context
parameters( 'datastore mcds wordlist mywl' )
/

select score(1),id,text from names where contains( text, '

  
    
       XX1 kind XX2 
       kind
    
  

', 1) > 0
order by score(1) desc
/
```
Output of this is:
```

     52         2 just, kind
      2         1 just and kind, kind and loving

MB of Pass value to bind variable Groove
Hello world. my version is 11.1.2.2

I have a bean managed on the basis that contains two components of input (ex: name of user, pswd)
I'm moving the input value to a query of VO that have variables bind with Groove. as adf.context.current...
If it is possible, what is the expression to access the value of the bean components managed?

THX
Just follow this
(1) for the vo, generate the VOImpl and when you create, select the variable bind method also
(2) has the VOimpl who take a parameter, set the varialbe bind using the method and run the query method
(3) expose this method as a customer interface
(4) in the pagedefinition file, create an action method and select this method and have a binding method
(5) of the managed bean, use the following code to execute the method
```
OperationBinding operation = bindings.getOperationBinding("operation_name");
         operation.getParamsMap().put("parameter_name", parameterValue); /// this will be u r bind variable parameter
         operation.execute();
         if (operation.getResult() != null) {
                  Boolean result = (Boolean) operation.getResult(); // cast to the expected result type
        }
```

Using 'text field contains comma-separated values' on a parameter of %
Hello

I use a parameter that has more than one value to be entered, separated by commas. I checked the box 'text field contains values separated by commas' for the parameter and set the sql code by using the operator 'in' so that the column will look in the multiple input values (e.g. family name in (: surname_par)). However, as passing multiple values parameter must also be able to manage %'s. As the sql uses the 'in' operator, BI Publisher brings back an error because % is supposed to bring all family names and not people with a last name of %. Is there a way to get around this?

Thank you
If you try to pass multiple values separated by commas and in addition also takes the query to return the data when the user types just in '%', then you could write something like this in your query:

Select * from table_name
where ((1 = DECODE (: surname_par, '%', 1, 0)) OR family name in (: surname_par))

I hope this helps. Please award points if helpful/correct.

If you need to more digits cos you're numbers are bigger, so you need to change the regular expression to pad with more than 0 (inbetween the \2 \1) and cut to the required length or replace the {noformat} {10} {noformat} with the number of digits required.

How do I see the bind variable values in the output of statspack
Hi all.

Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64 bit Production
PL/SQL Release 9.2.0.4.0 - Production

Run sprepsql.sql to get full sql and explain the plan of the hash value.
SQL returns with bind variable: 1: 2: 3, etc.
How can I know what are the values for bind variables in order to connect and run them in test db?

Thanks for your help.
You can't get the values to bind to StatsPack (AFAIK).

You have to draw a session that is running this / these SQLs (s) to capture the lie.
Or query V$ SQL_BIND_CAPTURE for the SQL when it runs.

Bind variables in Plsql
Since plsql automatically converts the variables in the where clause and the clause values in bind variable. So what is the difference between the two statements below?

create table t (number);

1)
declare
x number: = 109;
Start
Insert values into t (x); - plsql will make this variable as a variable binding, and provide the value of x in run mode.
exception when others then
dbms_output.put_line (SQLERRM);
end;

2)
declare
x number: = 109;
Start
immediately execute "insert into values t (: B1)" using x. -the user has explicitly used bind variable.
dbms_output.put_line (SQLERRM);
end;
[EDIT: after further testing, I redesigned my original explanation because Rahul referenced below.]

((1) SQL static, 2) is the dynamic SQL code. Static SQL is parsed to less than dynamic SQL statements.

As you make these calls in PL/SQL anonymous blocks and not in the stored procedures, there will be some analysis every time. Analysis of the static SQL will do less work than the analysis of the dynamic SQL, but both will avoid "hard" analysis which adds the execution plan to the shared pool.

Histograms and bind variables

Hi guys,.
When a SQL using bind variables histograms afftect the excution plan how?

For example
There is a table 'TEST' a column a number, varchar2 (100) b, c. tank (100).
100000 rows in this table and the 90000 column rows a value is 1, the other value is 2-10 by 100rows.

Now this column a histogram and a btree index only has on a;

Here is sample code
number of a_v var;
exec: a_v: = 10;

Select * from test where a =: a_v.

The plan of the excution is full table scan.

If I don't use of variable binding. It will scan the index.

I remember that a document mentioned that "do not use histograms using bind variables.

But why?

I disabled same bind variable peeking?

Thank you guys. Looking forward to your response.

Longfei Wei says:
Thanks Centinul this article is useful for me, but it is not explained why histograms do not work well with bind variables.

Thanks again.

Longfei,

Jonathan Lewis article is very good - another look at this article. Histograms peuvent work with bind variable, but the end result is usually not the desired result. Bind variables are used to reduce the number of different execution plans. The histograms are used to find what is supposed to be the best execution plan for the predicates provided and in the case of the bind variables, those are peeked from the bind variable values. Thus, if you have a histogram on a column and for hard analysis of a SQL statement and the most common value in this column is presented in the binding variable - this execution plan is considered by the optimizer to be the 'best' execution plan for the bind variable values provided. Suppose now that instead the less popular value in the column is specified - the optimizer peut produce a very different for the same SQL statement execution plan, which is optimized for the less popular value (this can be a scan of the index systematic range, rather than a full table scan). Now suppose the execution plan may not change when change of variable values bind - if you have a single popular value and many unpopular values, if the analysis lasts is performed with the popular single value, you might find that all subsequent runs of this SQL statement to perform full table scans, even if only a few rows in the table are selected.

Here's a quick test on the Oracle 11.2.0.2 database to demonstrate:

CREATE TABLE T1 (
  C1 NUMBER,
  C2 NUMBER,
  C3 VARCHAR2(300));

INSERT INTO
  T1
SELECT
  *
FROM
  (SELECT
    ROWNUM C1,
    DECODE(MOD(ROWNUM,100),99,99,1) C2,
    RPAD('A',300,'A') C3
  FROM
    DUAL
  CONNECT BY
    LEVEL <= 1000000)
ORDER BY
  C2;

CREATE INDEX IND_T1_C2 ON T1(C2);

EXEC DBMS_STATS.GATHER_TABLE_STATS(OWNNAME=>USER,TABNAME=>'T1',CASCADE=>TRUE,METHOD_OPT=>'FOR ALL INDEXED COLUMNS SIZE 254')

The foregoing has created a table with 1 000 000 lines where 99% of the lines have a value of 1 in C2 and 1% have a value of 99, and lines are inserted with a perfect setting in cluster factor because of the ORDER BY clause. A histogram has been created on the indexed column.

Let's try a test, we'll search a unpopular value 2 for the connection variable:

VARIABLE N1 NUMBER
EXEC :N1:=2

SELECT /*+ GATHER_PLAN_STATISTICS */
  C1,
  C2
FROM
  T1
WHERE
  C2 = :N1;

no rows selected

SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR(NULL,NULL,'ALLSTATS LAST'));

SQL_ID  c7su63uw7nch6, child number 0

------------------------------------------------------------------------------------------------------------

Predicate Information (identified by operation id):

   2 - access("C2"=:N1)

Thus, there is no selected row, the optimizer predicts that 5 957 lines would be returned and a path to the index has been selected. Path of this index would also be appropriate for the value of the bind variable 1? We will continue the trial, this time by choosing the 99 for the binding variable value:

EXEC :N1:=99
SET TIMING ON

  C2

  T1

Once more, the optimizer predicts 5 957 lines could be found even if 10,000 rows have been retrieved. Note also that the number of children is always 0. We will continue the trial, this time with the bind variable value of 1:

EXEC :N1:=1

SET AUTOTRACE TRACEONLY STATISTICS

  T1

The foregoing is the execution plan for CHILD_NUMBER 2 - notice that this time he reports 990 000 recovered lines, it's the execution that was used - adaptive cursor sharing plan do not have take effect and force the re-evaluation of the implementation plan - implementation plan has NOT been changed for a full table scan. That's the risk you take if you allow histograms on columns that have an uneven distribution of values and bind variables are used in the WHERE clause that refers to the column.

read the value of the variable binding
Hello

I was debugging a java application and in the process, I wanted to know what values the request as a bind variable. So, I checked v$ sql_bind_capture and activated the trace on the session. Unfortunately the data type is TIMESTAMP, so the view did not show a value and I got the trace was a memory dump that is not helpful for me:
```
 Bind#1
  oacdty=180 mxl=11(11) mxlc=00 mal=00 scl=00 pre=00
  oacflg=03 fl2=1000000 frm=01 csi=873 siz=0 off=24
  kxsbbbfp=fffffd7ffdb6fbd0  bln=11  avl=07  flg=01
  value=
Dump of memory from 0xFFFFFD7FFDB6FBD0 to 0xFFFFFD7FFDB6FBD7
FFFFFD7FFDB6FBD0 0D0B6C78 00010101                    [xl......]
```
Is there a function/method to convert a timestamp or at least vice versa?
Just run this little test:
```
SQL> CREATE TABLE t (c1 TIMESTAMP);

Table created.

SQL> INSERT INTO t VALUES (TRUNC(SYSTIMESTAMP));

1 row created.

SQL> COMMIT;

Commit complete.

SQL> SELECT TO_CHAR(c1) FROM t
  2  UNION
  3  SELECT DUMP(c1) FROM t;

TO_CHAR(C1)
--------------------------------------------------------------------------------
13-NOV-08 00.00.00.000000
Typ=180 Len=7: 120,108,11,13,1,1,1
```
Convert decimal to hex you gives 78, 6 C, 0, 0 D, 01, 01, 01 what byte order accountant reverse is the same as your memory dump. So I think the bind value is 00:00:00:000000 November 13, 2008.

Not very well how to recover of the hexagon directly at the time, but I do not know someone knows!

In fact, Google has been very helpful... take 100 on the first two decimal values: 120-100 = 20; 108-100 = 08, to give you the year: 2008. Then 11 and 13 are the month and day. The rest is hour + 1 minute + 1, the second + 1. So just convert your hex decimal and you should be able to discern the value!

How can I pass a value to a variable binding in a report query?

I did a query of report to print a PDF report, with a dinamyc source query that has a connection variable, like this:
SELECT EMPNO, EMPNAME, EMPDEPT
FROM EMP
WHERE EMPNO =: PARAMETER;
I want to call the report print directly from a page, by using the url print showed by apex:
f? p = & APP_ID.:0 : & SESSION. : PRINT_REPORT = MYREPORT
How can I pass the value of the variable binding: PARAMETER using this URL?

I don't think you can use the url parameter passes in a report query.

the binding variable: PARAMETER must be a page element or an element of the application.

use the "include session information and application" in the defination of report query to bind the value when the report is run

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}

How to set the value of the variable bind in VO on page load?

Hello, I use JDeveloper 11.1.2.3.0.
I created a VO in my application that uses a variable binding in the where clause. I want to put the value of this variable on the loading of the page automatically.
I read that I can do this through setNamedWhereClauseParam()... but I can't find out where and how to use it.
Can anyone help please?

You can put in different places:

AppModuleImpl,

ViewObjectImpl,

ViewRowImpl

Just him export the customer interface and use whenever you want

Get the value of the bind variable in backing bean class VO Impl
Hello

I have a VO that includes a bind "pOrgId" variable, the VO has a java VO Impl class that includes:

/**
* Returns the value of the variable to pOrgId.
value of the variable * @return for pOrgId
*/
public {getpOrgId() number
return (Number) ensureVariableManager () .getVariableValue ("pOrgId");
}

So it is possible to obtain the value is concluded by the binding variable using this class in a backing bean? (I tried to import the VOImpl class in the bean to support, but getpOrgId is not available?).

(JDEV 11.1.2.3.0)

Concerning
Carl
Hello

When you create a ViewObjectImpl class, none of these options is to generate the getter/setter for bind variable. Create a client class interface and expose the get method for the variable binding. Now, you can reference the method since a binding method in the ADF, which you then access a managed bean by calling
```
  BindingContext bctx = BindingContext.getCurrent();
  BindingContainer bindings = bctx.getCurrentBindingsEntry();
  OperationBinding oper = (OperationBinding) bindings.get("name of the method binding");
  Object returnVal = oper.execute();
```
