form of bad bind variable error in oracle 10g

I have a created a table in oracle database 10g
create table myimage (image_id number, nom_image BLOB);

I want to insert an image and recover an image through programming (don't want to block level) in oracle 10 g shape

without using java Bean (and finely working in the two windows XP2 and Solaries)

How can I do this please can someone give me the source code to do it because I am new in oracle forms.

I need an immediate replay to this answer why because I urgently need it in my project web ERP

You can use for WEBUTIL do, but

without using java Bean (and finely working in the two windows XP2 and Solaries)

WEBUTIL also contains javabean. I don't know why you have this restriction, I would say that you do not succeed without any java bean.

Thanks for help.

Based on the declaration of the customer table you posted columns are created in lowercase. Therefore, you must use the names of column between quotation marks:

create or replace

If your DB is 11g, you can try this

CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
BEFORE
insert on "TAKEOVER_USERS"
for each row
begin
:NEW.TAKEOVER_UID:=TAKEOVER_UID.nextval;
end;

If 10g or more...

CREATE OR REPLACE TRIGGER  "TAKEOVER_USERS_T1"
BEFORE
insert on "TAKEOVER_USERS"
for each ROW
BEGIN
SELECT TAKEOVER_UID.NEXTVAL INTO :NEW.TAKEOVER_UID FROM dual;

Making my first attempt to bind variables. What I've read it really improves performance.

You do not specify bind variables by a colon ': ' prefix in PL/SQL.

The stored procedure generates a query using the string concatenation. If you remove your name from the variable of the colon you still don't use bind variables.

If you want to use bind variables you should consider the following:

1. use the DBMS_SQL package.
2. use EXECUTE IMMEDIATE with the USING clause.
3. use OPEN TO with the USING clause.

Each has different advantages/disadvantages.

If looks as if you want to pass in a dynamic list. If you are using bind variables, it will effectively address the entire list as a value surrounded by single quotes. If you really want a dynamic IN the list, you need to investigate another method.

Tom Kyte contains information about the lists into dynamic here: [how to make a variable in the list? | http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:210612357425]

You wrote trigger on the table of the student. So in the trigger, only the columns of this table must be offered for example: NEW.zip.

Since zip_id is not part of this table, the: NEW.zip_id must always generate the error.

insert into student_v (zip) values('111');

In the above statement, you can only provide the value for the column zip but not zip_id. Therefore, the: NEW.zip_id is not available in the trigger. Must extract this value in the sequence after it is created.

for example

create the test of the order;

INSERT INTO postal code

(zip,

zip_ID,

created_by,

CREATED_DATE,

Modified_By,

MODIFIED_DATE)

VALUES (: NEW.zip,)

test.nextval,

NULL,

Multiple selection with binding variable error

Hello world
I tried to put in place an array of adf multiple selection with another table, by following the tutorial (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/75-multi-parent-row-detail-views-328078.pdf), page 3.
I created all things and first of all I had an exception error, which I fixed, but now, whenever I try to select multiple lines, it won't update the table of the adf.
In this example, I choose a service line and it shows the emplooyes, but every time I try to choose another line by ctrl clicking on it, the employees table be updated.
Since I tryied to follow the tutorial, I'll put the code for the bean, I created for this purpose (it's a little different than the code given by the tutorial, but only because I had to get rid of the exception error)
I use jdeveloper Studio Edition Version 12.1.2.0.0.
Here is my code for the bean.java:
Select listen port defined for the departments table. The selected line keys are read in the reference table.
For each line, the Department ID value is read and added to a string buffer that generates a comma-delimited
List of the departmentIds. In the end, this string is passed as an argument to the link of action ExecuteWithParams
{} public void onDepartmentTableSelect (SelectionEvent selectionEvent)
variable to hold the string containing the selected set value line departmentId
StringBuffer departmentIds = new StringBuffer();
Go to the main table to read selected line keys
RicheTableau rt = selectionEvent.getSource ((richeTableau));
RKS RowKeySet = rt.getSelectedRowKeys ();
Iterator selectedRowsIterator = rks.iterator ();
memorize the current line to place it back in the end key
CurrentRowKey () rt.getRowKey = (list);
for each selected master line, determine the departmentId
int size = 0;
{while (selectedRowsIterator.hasNext ())}
size ++;
The rowKey () selectedRowsIterator.next = (list);
each value is terminated by a comma
If (departmentIds.length () > 0) {}
departmentIds.append(",");
}
take the current line
rt.setRowKey (rowKey);
JUCtrlHierNodeBinding wrappedRow = rt.getRowData ((JUCtrlHierNodeBinding));
Line rw = wrappedRow.getRow ();
/*
Number departmentId = (number) rw.getAttribute ("DepartmentId");
*/
int departmentIdInt = rw.getAttribute ("DepartmentId") (Integer);
oracle.jbo.domain.Number departmentId = new oracle.jbo.domain.Number (departmentIdInt);
departmentIds.append (departmentId.stringValue ());
}
back the foreign currency on the line
rt.setRowKey (currentRowKey);
Run the query on the detail table
BindingContext bctx = BindingContext.getCurrent ();
BindingContainer links = bctx.getCurrentBindingsEntry ();
OperationBinding executeWithParams = bindings.getOperationBinding("ExecuteWithParams");
executeWithParams.getParamsMap () .put ("departmentIds", departmentIds.toString ());
executeWithParams.execute ();
refresh the detail table
AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance ();
adfFacesContext.addPartialTarget (employeeTable);
}
}
If someone has an idea of why it isn't updated table, please answer. Any idea can help.
Thanks in advance.
Greetings,
Frederico Barracha.

Finally, I found the problem...

The problem was that I had to remove a line in the properties of my table, the property services: selectedrowkeys, because he only spent the last selected row.

Yet, I apreciate the help and I had to replace a code in the bean.java, in reason of the exception error and you had to do. Maybe I did a configuration in the wrong way and he would not.

Thanks for the help.

Kind regards

Frederico.

Bad connection variable? I'm doing a host variable.
Okay, so I said a global variable:

VARIABLE g_total NUMBER

and I want to use this variable to store the results of a stored procedure (I reduced my code to focus on the problem area):

CREATE OR REPLACE PROCEDURE my_procedure
(p_price IN m_movies.price%TYPE
p_quantity IN m_cart.quantity%TYPE)
IS
BEGIN
: g_total: = p_price * p_quantity;
DBMS_OUTPUT. Put_line ("the order total is: ' |: g_total");
END;
/

After all this, I get an error "bad bind variable g_total ' for the two lines I use it inside the procedure. What the heck is a variable binding? I use a host variable. (I think). If this has nothing to do with the fact that I can only give a very generic NUMBER data type to the host variable? Help, please!
It's not the way it will work. You cannot create choice with lie (as you saw).
You had rather code like this:
```
SQL> VARIABLE g_total NUMBER

SQL> create or replace procedure my_procedure (p_price      in     number,
                                          p_quantity   in     integer,
                                          g_total         out number)
is
begin
   g_total := p_price * p_quantity;
end my_procedure;

What is the value of your cursor_sharing parameter?

If that is CORRECT they will share the SQL area only when their texts match exactly.
You need to put STRENGTH to similar statements to share SQL or SIMILAR.

Using Bind Variable in a SELECT statement
Hello

I am trying to build my SQL query running using bind variables and in Oracle® Fusion Middleware Fusion developer Guide for Oracle Application Development Framework 11 g Release 1 (11.1.1) it is said that ' after you define bind variables, the next step is to reference them in the SQL statement. While SQL syntax allows you to bind variables to appear in the SELECT list and in the WHERE clause, you'll generally use them in this context, as part of your WHERE clause. ».

However, when I try to use bind variables in my SELECT list because I had set a type to the string of the variable variable is inserted with quotes each side for example SELECT TestTable FROM 'Service '. Is it possible to use bind variables to insert a value in my list of selection without the quotes around it?

Thanks in advance,
Tom
Hi Robinst,

I think you want to set up column name of the table that is not possible using bind variables. With the help of the bind variables you can send a value to the SQL. The String value is therefore always with inverted commas.

Kind regards

Oracle 10g and 11g reports

I recently upgraded from Oracle Forms/Reports 10 g and 11g. Oracle 10g reports saving as PDF is easily converted into a word document, however, Oracle 11 g converts not as 10 g. What is the difference and how to make the report of 11g saved in a PDF file be able to convert a Microsoft Word document itself.
Thank you

Hello

There is a "known issue" with the PDF file in 11g:

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.

The view was created with quotes around column names, so that they are case-sensitive. You need to either modify your trigger double quote column names, or rebuild the view without the quotes. Personally, I'd go with changing the display.

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.

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.
