Pl Dynamic sql help needed

Hello Everyone
I am using database 11g. Can someone pl suggest what are the rules for putting single quotes for dynamic sql like
1) how many single quotes before/after a sql statement .
2) Rules for putting single quotes if there exists i) a variable in the sql statement
ii) a constant for e.g 100 in the sql statment.
If you could give the answers with a simple select statement, it will be even better !!!
Thanks and regards
Gautam

Gautamwrite the SQL statement as you would for any SQL client & enclose it using Q-quote

Dynamic SQL help!

I'm trying to build a update statement with different operator which setup from a table and passed. Not sure how to build it. Please help
PROCEDURE my_update
p_id            IN NUMBER,
p_var1          IN NUMBER,
my_value        IN VARCHAR2,
my_operator     IN VARCHAR2,
x_return_status OUT VARCHAR2,
x_errors        OUT VARCHAR2
) IS
l_dynamic_string VARCHAR2(4000);
BEGIN
l_dynamic_string := table_b.col2 ||
                    rec.my_operator /* value as: "=" OR "LIKE" */ ||
                    my_value /* VALUE AS "2233" OR "900%" */
UPDATE table_b
     SET col1 = ''
   WHERE id = p_id
     AND l_dynamic_string
     AND id = (SELECT table_a.id
                 FROM table_a
                WHERE id = p_id
                  AND col_a = p_var1);
EXCEPTION
WHEN OTHERS THEN
    NULL;
END my_update;

Hi,
What you posted can probably be done without dynamic SQL. If the expression after LIKE does not conatin a wild-card, then LIKE behaves just like =. You can probably arrange things so that the query always uses LIKE.
If you need dynamic SQL, then use EXECUTE IMMEDIATE to perform it.
I think you want something like this:
PROCEDURE my_update
p_id            IN NUMBER,
p_var1          IN NUMBER,
my_value        IN VARCHAR2,
my_operator     IN VARCHAR2,
x_return_status OUT VARCHAR2,
x_errors        OUT VARCHAR2
) IS
l_dynamic_string VARCHAR2 (4000);
l_update_txt        VARCHAR2 (4000);
BEGIN
    l_dynamic_string := table_b.col2 || ' '     -- If my_operator is LIKE you'll need a space here
                                    || my_operator               /* value as: "=" OR "LIKE" */
                         || Q'< '>'
                         || my_value            /* VALUE AS "2233" OR "900%" */
                         || Q'<' >'
    l_update_txt := 'UPDATE table_b'
                || '   SET col1 = NULL'
              || ' WHERE id = p_id'
                || '   AND ' || l_dynamic_string
                || '   AND id = (SELECT table_a.id'
                 || '                     FROM table_a'
                 || '             WHERE id = p_id
                 || '               AND col_a = p_var1)';
    dbms_output.put_line (l_update_txt || ' = l_update_txt in my_update');
-- EXECUTE IMMEDIATE l_update_txt;
--     No EXCEPTION hider
END my_update;While writing dynamic SQL, it's a good idea to display the dynamic text. I used put_line to do that. Remember to comment out (or remove) the display code when testing is finished.
Notice that the EXECUTE IMMEDIATE command is commented out. Only after you've tested some, and you think l_update_txt is correct, should you un-commnet that line.
Never say "EXCEPTION WHEN OTHERS THEN NULL;"
Error messages help you, especially duting development when you're likely to have lots of coding errors.
If you really need to keep the program running after encountering certain errors, then it's okay to have an EXCEPTION block, but your use of either "WHEN OTHERS" or "THEN NULL" should be very limited, and you should not use both of them together.

Dynamic Action-help needed

Hi ,
My requirement is in dynamic Action I need to delimit all records in a Subtype of an Infotype and create New record for these records with BEGDA as ENDDA + 1 of the delimited records.
Iam able to delimit all records in the Subtype but , Iam not able to create new records.
My code for delimiting is as given below, in T588Z,
9901 2 06 801 P P9901-SUBTY='2'
9901 2 06 802 P PSYST-IOPER='MOD'
9901 2 06 803 P P9901-STATS='X'

9901 3 06 810 W P9901-ENDDA=RP50D-ZZDATE3
The above code is working fine.
My code for creating new record is as given below, even though the control is oing to the subroutine, INS statement is not working, and hence new record is not getting created.
9901 3 06 811 P SY-UCOMM='UPD'
9901 3 06 812 P PSAVE-ENDDA<>P9901-ENDDA

9901 3 06 817 W P9901-ENDDA='99991231'
Kindly help me on this.
Thanks in Advance

hi,
thankyou for all ur valuable replies.
Time constraint for this custom infotype is 2.
It is not allowing to create a new subtype record if 1 exists.
Here scenerio is
Each Subtype ,ie, Subtp 2 ad 3 has got 4 records each with distinct OBJPS field.
when STATS field of subtype 2 is changed for any 1 record in Subtype 2, corresponding record in Subtype 3 should get delimited .
And, rest of the records of Subtype 3 should get created again with new start date.
The code I have written for this is ,
9901     2          06     800           *BEG*****DEATH OF WIDOW*****************

Dynamic SQL Help - Getting Errors

Basically I have a table with employee data, and I'm trying to create a dynamic PL / SQL block that creates a new table and copies over the data from employee table to the new one.
I'm teaching myself dynamic SQL so this is practice. Please don't offer "better solutions" because I'm sure there are plenty - I'm just looking to complete the code as is so I better understand this query language.
Here is my code:
set serveroutput on size 10000
declare
cursor c is
select table_name, tablespace_name
from user_tables where table_name = 'EMP';
cursor c2 is
select table_name, column_name, data_length, data_type, data_precision
from user_tab_cols where table_name = 'EMP';
cursor c3 is
select *
from emp;
counter number(3);
counter := 0;
begin
for i in c loop
if (counter = 0) then
create table emp2;
insert into emp2 table_name, tablespace_name;
for i in c2 loop
insert into emp2 table_name, column_name, data_length, data_type, data_precision;
counter := counter + 1;
end loop;
end loop;
for i in c3 loop
insert into emp2 empno, ename, job, mgr, hiredate, sal, comm, deptno;
end loop;
end;
Here are my errors:

This is more of a presentation layer problem I would not handle it in SQL. For example if the presentation layer is SQL Plus you can use BREAK command, like this.
SQL> select * from table_a;
      CODE NAME       CITY       DEPT
         1 ABC        EA         A
         1 ABC        EA1        A
         2 BCD        EA2        A
         2 ABC        EA3        A
         3 KBC        EA         A
         3 ABC        EA         A
6 rows selected.
SQL> break on code
SQL>
SQL> select * from table_a order by code;
      CODE NAME       CITY       DEPT
         1 ABC        EA         A
           ABC        EA1        A
         2 BCD        EA2        A
           ABC        EA3        A

           ABC        EA         A

But if you still wish to do it in SQL the right way is to use ROW_NUMBER like this.

breaks cleared

Creating a byte Array dynamically.Urgent Help needed.

Hi there,
I need to create a byte Array with the values
derived from the array and then am passing this byte array
to a method.
Example :
public static void main(String[] args) throws IOException {
char chars[] = {'a','j','a','y'};
byte[] b = {
(byte) chars[0],(byte) chars[1],(byte) chars[2],(byte) chars[3],
//** Send name to a server.
sendRequest(b);
This is all right.
But here I know the size of the character array chars.
If it had more than 4 characters or less than 4,
is there a way to create the byte array dynamically based on the values in the character array?
Please can some one help me with creating a byte array on the fly?
Has anyone understood my question please?
A response is much much appreciated.

The actual problem is this.
The byte array already has some fixed values to it
and i need to append the values of the character array
to this byte array
ie
char chars[] = {'a','j','a','y'};
byte b[] = {
// Predefined values
(byte) 0x01, (byte) 0x7E, (byte)0x03
// I have to add the values from the array here
(byte) chars[0], (byte) chars[1]....
How can I add these values.? The size of the character array
can vary

Dynamic Calendar help needed

I am trying to convert a static events calendar to dynamic
and I have run
into a couple of snags that I don't seem to be able to figure
out (darned
Newbies!)
The big problem that I am having is to have the Month/Year
header display
only one time for all the events in that month.
The second problem is displaying a range of dates for one
event (...Sept
9-12)
Example:
September 2006
Sept 1 - event 1, location
Sept 9-12 - event 2, location
Sept 14-16 - event 3, location
October 2006
Oct 3-4 - event 1, location
Oct 23 - event 2, location
This is the type of calendar I'm trying to dynamisize looks
like this one
http://internationalsoaringeaglesministries.org/calendar.htm
It is not loaded with all sorts of dates so I chose to
display only dates
with events on them.
Any help would be much appreciated!!
Thanks
Dave

Re: Including Applet in JSP with Dynamic input| Help needed

Hi All,
We are into a project in Oracle Portal Server where in we want to embed a result of a standalone application in Portal page.
We can do that once we can embed the result of the standalone application which generates applet based on the input it gets from the current application's database.
If it was static we could have used jsp:plugin but, it fails in our case!
We are clueless as to how to embed an applet which will pick up the data dynamically.
Can anyone of you help me in this regard?
Thanks & Regards
Arthi

Hi Arthi,
I think this might help you to get an idea why jsp:plugin tag does not allow for dynamically called applets.
<jsp:plugin type=applet height="100%" width="100%"
archive="myjarfile.jar,myotherjar.jar"
codebase="/applets"
code="com.foo.MyApplet" >
<jsp:params>
<jsp:param name="enableDebug" value="true" />
</jsp:params>
<jsp:fallback>
Your browser does not support applets.
</jsp:fallback>
</jsp:plugin>
The plugin example illustrates a <html> uniform way of embedding applets in a web page. Before the advent of the <OBJECT> tag, there was no common way of embedding applets. This tag is poorly designed and hopefully future specs will allow for dynamic attributes (height="${param.height}", code="${chart}", etc) and dynamic parameters. Currently, the jsp:plugin tag does not allow for dynamically called applets. For example, if you have a charting applet that requires the data points to be passed in as parameters, you can't use jsp:params unless the number of data points are constant. You can't, for example, loop through a ResultSet to create the jsp:param tags. You have to hand code each jsp:param tag. Each of those jsp:param tags however can have a dynamic name and a dynamic value.
I think you can get better information if you look in to the below link

Dynamic VTI help needed!

Hi all,
I currently have an "ordinary" site-to-site VPN with static crypto maps at the spokes and a dynamic crypto map at the headend.
What I'd like to do is replace this with static VTIs at the spokes and a dynamic VTI at the headend. I don't need any of the "flash" of DMVPN, just as straight a swap as I can possibly get.
The static VTIs are no problem, but I'm really confused about how to set up the dynamic VTI at the headend. I don't see how the DVTI gets associated with an interface, and which IP address the spoke should use to initiate the tunnel.
Could anybody please post a simple (but complete) config for a DVTI hub and a SVTI spoke?
many thanks,
alec

Configuring the Cisco IOS? Server Load Balancer (SLB) feature to distribute large numbers of IP Security (IPsec) tunnels onto a Cisco 7200/7301 IPsec server farm. The server farm hubs are configured with dynamic Virtual Tunnel Interface (VTI) while the remote spokes can be configured using VTI or crypto maps (supporting single proxy).

Dynamic sort help needed

I am trying to implement a dynamic sort using pl/sql procedure
with two IN params, which tell what column to sort by
and wich direction. smth. like this
procedure getEmployees (p_dept_no in employee.dept_no%type,
p_sortBy in varchar2,
p_sortDir in varchar2
p_empl_cur in out emplCur
) is
begin
OPEN p_empl_cur
FOR
SELECT EMP_ID, F_NAME, L_NAME
FROM EMPLOYEE
WHERE DEPT_NO=p_dept_no
ORDER BY p_sortBy p_sortDir ; --> this is the part that does not work
-- I make sure that the params values are correct
-- possible p_sortBy values: EMP_ID, F_NAME, L_NAME
-- and p_sortDir: 'ASC' or 'DESC'
end getEmployees;
Thank you in advance.

Try execute immediate.
Some thing like this:
PROCEDURE GETEMPLOYEES (P_DEPT_NO IN EMPLOYEE.DEPT_NO%TYPE,
P_SORTBY IN VARCHAR2,
P_SORTDIR IN VARCHAR2
P_EMPL_CUR IN OUT EMPLCUR
) IS
BEGIN
OPEN P_EMPL_CUR
FOR
SORT_SQL := NULL;
SORT_SQL := 'SELECT EMP_ID, F_NAME, L_NAME FROM EMPLOYEE'||
' WHERE DEPT_NO=P_DEPT_NO '||
' ORDER BY '||P_SORTBY||' '||P_SORTDIR||';'
EXECUTE IMMEDIATE SORT_SQL INTO P_EMPL_CUR;
Thanks

Sql help needed

sql gurus
Oracle 11.2.0.2

Is it possible to do thru sql to get this done
pl. let me know.
I hope I have explained the problem clearly

Hi,
gl**** wrote:
... I hope I have explained the problem clearlyNo matter how clearly you explain a problem, you still ought to post CREATE TABLE and INSERT statements for some sample data, and the results you want from that data, as Hoek said. Explain how you get the results you want from that data. For example, you talk about getting rows 1 through (N/3), but you haven't said what determines the order of the rows. (In the query below, I assume it's a column called column_1.)
Simplify the problem when you can. For example, instead of having 100 to 150 rows, post a problem that involves 6 to 8 rows.
One way to do this in pure SQL is to use the NTILE function to divide the results evenly (as evenly as possible) into 3 groups, and only display one of the groups at a time, like this:
WITH   got_third     AS
     SELECT     x.*
     ,     NTILE (3) OVER (ORDER BY column_1)     AS third
     FROM     table_x x
     WHERE     ...      -- If you need any filtering, put it here
SELECT     *     -- Or list all columns except third
FROM     got_third
WHERE     third     = :third_wanted
;It would be more efficient if you generated all of the results at once, and then divided the output file into 3 parts, but an inefficient solution might be acceptable in this case.

XML SQL help needed

I am having trouble using OracleXML getXML, after
setting all the path variables in env.csh I try
java OracleXML getXML -user "user/passwd" "select a, b from blog"
but get the following error.
ORA-01019: unable to allocate memory in the user side
The same error occurs for jdk1.1.7 and jdk1.2
null

Hi Dean,
It might be something to do with connecting through oci8 to the
Oracle executable. ( I am not sure since I dont know ur
configuration etc..). BTW what release of Oracle is this?
One thing for you to try out would be to write a small java
program against the OracleXMLQuery class to see if that works.
I have attached a very simple program below:-
import java.sql.*;
import java.math.*;
import oracle.xml.sql.query.*;
import oracle.jdbc.*;
import oracle.jdbc.driver.*;
public class testXML{
public static void main(String args[]) throws SQLException
DriverManager.registerDriver
(new oracle.jdbc.driver.OracleDriver());
Connection conn = (Connection)
DriverManager.getConnection("jdbc:oracle:oci8:scott/tiger@");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select * from emp");
OracleXMLQuery qry = new OracleXMLQuery(conn,rset);
String xmlString = qry.getXMLString();
System.out.println(" OUPUT IS "+xmlString);
This code does a select from emp table available in scott/tiger
schema. U can change the login and the table names
appropriately. SEtup all the environment variables etc.. (see
release notes), save this as testXML.java, run javac to get the
class and execute it using "java testXML". If this doesnt work,
try changing the getConnection line to use the thin jdbc, such
as,
DriverManager.getConnection
("jdbc:oracle:thin:@","scott","tiger");
You can check out the JDBC documentation for how to specify
your connection for your particular setup (such as specifying
the port number etc.. if needed).
Lemme know if it works,
Murali
