Number of Parameter of dynamic statement

How i can get the number of parameter tobe set of dynamic statements.
Example:
I got a string with a placeholders to be interpreted as a statement and I create a statament using the string.
"select * from MyTable where Name like :1 AND Surname like :2Â¨
Is there any way available to get the number of parameter?

No, I that's the result set... I need the number of bind variables that need to be set to avoid a "not all variables bound" error at execute time.
I realize that it is a bit tricky to get that (due to input and output vars, vars having same names, etc.), but OCI has it and I was hoping a C++ wrapper existed. And I do get a runtime error when I try to set a variable that doesn't exist, so internally the number must be known.
Thanks for trying, anyway.

Using a record as parameter in dynamic SQL

Hi,
I'm trying to pass a record (%rowtype) as parameter
to a procedure which i call from inside a dynamic statement. This doesnt seem to work however, I get the reply "not a valid sql-statement".
Apparently, Oracle does not allow for this since records are not a SQL-type but a PL/SQL-type.
Have anyone found a way around this?
(Except for the obvious to pass just the primary key and
populate the record inside the procedure).
The code looks like:
declare
v_rec employee%rowtype;
v_stmt varchar2(500);
begin
select *
          into v_rec
          from emplyee
          where rownum = 1;
v_stmt := 'some_proc ( :param )';
execute immediate v_stmt using v_rec;
end;
Any advice appreciated,
Thanks

Hi,
Here's a example of something similar which we had done for the data conversion excercise recently.
The script uses dynmanic PL/SQL block and executes it using Execute Immediate. AAnd within the dynamic PL/SQL block, a procedure Pr_Pb_Test is called which takes in %ROWTYPE as ainput parameter.
See if this helps.

Help with dynamic statement returning values into collection

create or replace type num_ntt is table of number;
create or replace type vc2_ntt is table of varchar2(30);
create or replace
package pkg
as
type rec is record(
      pk        num_ntt,
      id_batch vc2_ntt
procedure p(
      p_count in number,
      p_rt    out nocopy rec
end pkg;

By the way, I don't see why you are using dynamic SQL here. Static SQL will do just fine. And so you can literally copy Adrian's setup.

Related to using dynamic statements

Hi,
Just when defining cursors, are there any other ways, by which we can use any dynamic statements? Such as depending on different conditions, we want to have different 'where' clauses.
Thks & Rgds,
HuaMin

For a straight in-line cursor which is what I think you are requiring, the closest thing I can think of would be something like....
PROCEDURE myproc(p_x IN NUMBER := NULL, p_y IN NUMBER := NULL, p_z IN NUMBER := NULL) IS
CURSOR cur_mycursor
SELECT a,b,c,d
FROM   mytable
WHERE x = NVL(p_x, x)
AND    y = NVL(p_y, y)
AND    z = NVL(p_z, z);Obviously this is a basic example showing how you can restrict the query on just the values you supply, but you could adapt for more complex things.

Pass table name as parameter in prepared Statement

Can I pass table name as parameter in prepared Statement
for example
select * from ? where name =?
when i use setString method for passing parameters this method append single colon before and after of this parameter but table name should be send with out colon as SQL Spec.
I have another way to make sql query in programing but i have a case where i have limitation of that thing so please tell me is it possible with prepared Statment SetXXx methods or not ?
Thanks

Well, I would say (ugly as it is) String concatenation, or stored procedures.

Report to display number of items sold by state

Hello experts,
I would need a report with the following paramters:
Deliver doc number,posting date,ship to state,item number,item desc,quantity.Is it possible to have the selection for the date range?
Thanks

Hello Gordon,
This is what I noticed.
This query shows the ship to state for the order if they are not on the User defined fields on a delivery document.
Let me be more clear
This query is displaying only the customers where the ship to address is entered in the BP master data.If the ship to address is entered at the sales order level it is not displaying the ship to state.
I hope this makes sense
Thanks

Parameter with Dynamic prompt - bug encountered

I am using CRD XI release 2 (SP2) against an Oracle 10 release 2 database
I have a report fully working with a static parameter
1. But I have an issue when trying to introduce a parameter with dynamic prompts
I have a data source (PointofSale retrieving data from a database view)
I am trying to have the newPointOfSale parameter to prompt the user for values taken out of the PointOfSale source.
I set up the parameter as indicated by the Crystal RD210 Guide.
But when I run the report I am prompted for Server Name(greyed out)/user name/password(something I have never had to do for this report until introducing the dynamic parameter)
In doubt I enter these of the database user I am using as a source for this report
I get a strange error message telling me there is a problem with another datasource on the report.
'Prompting failed with the following error message: 'List of Values failure: fail to get values. [Cause of erro: The table 'DLEX_REPORT.DLEX_REPORT_RETRIEVE.AIRLEGSUMMARY_SUM' could noyt be found. UNKNOWN.RPT]'.
Error source: prompt.ddl Error code 0x8004380D
There seem to be bug with parameters and dynamic list of values in Crystal as other people seem to encounter similar issue
Is there a fix or a workaround?
2. Also I believe this forum allows to escalate bugs with SAP/business objects. Does anyone know how to do this? As this is very obviously a bug....
Thanks
Philippe

I am not sure whether this will solve your problem since you are using a different implementation of Crystal Reports , but I've received the same error using CR XI Developer Release 2 in conjunction with the Crystal Reports Server XI Release 2. My solution was to go into the Business View Manager application and fix the Data Connection object associated with the problematic Dynamic prompt by supplying a user name and password for the data connection object and setting the "Runtime Prompt Mode" property to "Never Prompt". For some dumb reason, the Crystal Reports client will publish the data connection object to the Business Views database without any login credentials associated with it. So after creating such a prompt in a report, you have perform this extra step before running the report the first time. The good news is that if you reference this dynamic prompt in other reports, it will work - so you only need to fix it when it is first created.

Create "dynamic" statements in a stored procedure

hello
in my stored procedure I need to write a statement like this:
FUNCTION myfunct (mytable IN VARCHAR2)
BEGIN
EXECUTE IMMEDIATE
'SELECT COUNT(*)
INTO myvar
FROM ' || mytable ||
'WHERE mycol = ' || currval;
In short I need to create a sort of "dynamic" statement in which the tablename (nad other...) is a variable....
but I do not guess it's ok...
How can I do?

Hi,
With dyanmic SQL, the INTO clause is part of the EXECUTE IMMEDIATE statement, not the query.
Try something like this:
CREATE OR REPLACE FUNCTION     myfunct
(       mytable       IN     VARCHAR2
RETURN     PLS_INTEGER
IS
     return_num     PLS_INTEGER;
     sql_txt          VARCHAR2 (1000);
BEGIN
     sql_txt := 'SELECT COUNT (*)'
          || ' FROM ' || mytable;
     dbms_output.put_line (sql_txt || ' = sql_txt in myfunct');
--     EXECUTE IMMEDIATE sql_txt INTO return_num;
     RETURN     return_num;
END     myfunct
/It's a good idea to develop dynamic SQL as shown above; putting the dynamic statement into a variable that can easily be displayed for debugging.
When it looks right, then un-comment the EXECUTE IMMEDAITE statement.
Before moving the code into Production, comment out (or remove) the put_line statement.

Insert 'text' in dynamic statement

Just one very simple question:
I have
insert into nn_nodes (lfdnr, layer_, type_) values (lfdnr#, 0, 'input');and want to make it to a dynamic Statement.
How must I write the 'input'?
stmt# := 'insert into nn_nodes (lfdnr, layer_, type_) values (lfdnr#, 0, 'input');'divides the String into 2 parts and gives an Error Message,
stmt# := 'insert into nn_nodes (lfdnr, layer_, type_) values (lfdnr#, 0, '||'input'||');'don't take the '
Thanks for help!

Yet better - use bind variables:
'insert into nn_nodes (lfdnr, layer_, type_) values (:x,:y,:z)'Best regards

How do the dynamic state to record image in the cell-phone?

Excuse me.How do the dynamic state to record image in the cell-phone?Or whether it has the feasibility or not?..Somebody can give me some opinions and data,please.
Thanks.

I don't understand very well what you want, but to record and image (get and snapshot) you have to create an Player, realize the player, start it and then get the snapshot. ex:
            player = Manager.createPlayer("capture://video");
            player.realize();
            VideoControl videoControl = (VideoControl) player.getControl("VideoControl");
            player.start();
            byte[] data = videoControl.getSnapshot(null);
            Image image = Image.createImage(data, 0, data.length);To find out if a device can record images you can use this:
            boolean mmapiAvailable = System.getProperty("microedition.media.version") != null;
            boolean canGetSnapshots = System.getProperty("supports.video.capture") != null;Hope that answer your question.

I found several charges on my bank account from Apple on App that is completely free. After calling the number showing on my bank statement there an automated answering that tells you to go to apple website!!! There is nobody to talk to!! Complete rip OFF
And now because I want to communicate with apple support I have to go through the hectic website and community support, this is ridiculous.
I have 5 iPhones in my account and this makes me reconsider upgrading to iPhones again.
Why Apple put a phone number in the bank transaction, if there is nobody to talk to!!!!!!
I hope someone from Apple support can answer my question.

Go to getsupport.apple.com. Or, call 1-800-MYAPPLE.
Just because an app is free to download doesn't mean that there aren't in-app purchases available.
Go to iTunes on your computer, log into the iTunes Store with your Apple ID & password, and check your purchase history. Be advised that all iTunes & App Store purchases are final.
