HELP! With parsing Update statement

I am stuck and need help! The teacher has not gone over parsing with us and it is not on his scheduled topics list. But, I am a person that likes to scope out and learn new things. For our final project, we have to allow updates, delete and inserts into the 5 main tables of the Premiere Products database. I have done everything except for the updates. I can achieve the updates of the entities by pretty much hardcoding them and that is okay by the teacher, but I want to learn about parsing because Barbara from this site mentioned this to me.
This is what I was able to write and I am getting errors:
CREATE OR REPLACE PROCEDURE updatecust_proc (
v_cust_num IN customera.cust_num%TYPE,
v_attributetoupdate VARCHAR2 ,
v_updatedvalue VARCHAR2 )
AS
e_invalidcustnum_error EXCEPTION;
BEGIN
v_isvalidcustnum := iscust(v_cust_num);
IF (v_isvalidcustnum = FALSE) THEN
RAISE e_invalidcustnum_error;
END IF;
PARSE(
'UPDATE customer
SET' | | v_attributetoupdate | | '=' | | v_updatedvalue | |
'WHERE cust_num =' | | v_cust_num
END;
EXCEPTION
WHEN e_invalidcustnum_error THEN
DBMS_OUTPUT.PUT_LINE('Cannot be updated. Invalid customer number');
END;
Any help would be useful. I went to the Oracle help site but their examples are a little too complicated for me to understand, plus, I am not using any C code.
Thanks in advance!
Bob

I will try putting in spaces to the areas that you mentioned to me. Thanks!
I will try to explain the function just in case some other poeple don't understand what I am trying to do.
This procedure is supposed to update the CUSTOMER entity. This entity has 7 attributes and I don't want to write out 7 UPDATE statements to changes a value. Instead, I want the name of the attribute to be passed to the proceudre so that the UPDATE statement can know which attribute to use. Barbara mentioned something about parsing and I attempted to try it out, but I am getting errors. Can someone help me with the procedure. BTW, function iscust() returns TRUE if the customer number is valid, otherwise, it returns false.
Thanks,
Bob

Help with this update statement..

Hi everyone,
I am trying to update a column in a table .I need to update that column
with a function that takes patient_nbr and type_x column values as a parameter.
That table has almost "300,000" records. It is taking long time to complete
almost 60 min to 90 min.
Is it usual to take that much time to update that many records?
I dont know why it is taking this much time.Please help with this update statement.
select get_partner_id(SUBSTR(patient_nbr,1,9),type_x) partner_id from test_load;
(it is just taking 20 - 30 sec)
I am sure that it is not the problem with my function.
I tried the following update and merge statements .Please correct me if i am wrong
in the syntax and give me some suggestions how can i make the update statement fast.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);
merge into test_load a
using (select patient_nbr,type_x from test_load) b
on (a.patient_nbr = b.patient_nbr)
when matched
then
update
set a.partner_id = get_partner_id(SUBSTR(b.patient_nbr,1,9),b.type_x);
there is a index on patient_nbr column
and the statistics are gathered on this table.

Help with a update,select statement

Hi all please can you help me with a update statement i am struggling with.
I have 2 tables
Holiday and data
In the Holiday table i have columns for
Machine_ID NUMBER,
date_from DATE,
date_to DATE,
ID NUMBER
Machine column represents a type of machine, the two dates represent the start and end date of a holiday and ID represents the ID of the machines that the holiday effects (as you can have many machines that are the same, so the ID unique field to seperate them.
i.e.
996     25-DEC-08 00:00:00     27-DEC-08 00:00:00     91
996     25-DEC-08 00:00:00     27-DEC-08 00:00:00     92
100     28-DEC-08 00:00:00     29-DEC-08 00:00:00     1
100     28-DEC-08 00:00:00     29-DEC-08 00:00:00     2
In the data table i have the following columns:
DATE DATE
Machine NUMBER
SHIFT1S DATE
SHIFT1F DATE
SHIFT2S DATE
SHIFT2F DATE
CALS DATE
CALF DATE
CAP NUMBER
CALCAP NUMBER
total_hrs_up NUMBER
In here i have data for every date in the calendar. The machines are cross references with the machine in holidays table.
I run two shifts so have shift 1 start, finish. shift 2 start, finish. These are dates with times, so shift1s could be 01-01-08 09:00:00 shift1f could be 01-01-08 17:00:00.
shift2S could be 01-01-08 21:00:00 shift2f could be 01-01-08 23:59:00.
so that machine would be up between them hours of the day.
Other columns include
CALS, ,CALF = calendar start, finish, - This needs to be populated from the holiday table. currently null. So if the date is the 26 DEC and the machine is the same as what is in the holiday table then these two columns should be populated with them data
CAP is the total number of these machines i have available.
CALCAP is the no of machines the holiday affects -currently null
total_hrs_up is the number of hours this machine is up and running -currently null.
So what i need to do is populate the cals, calf calcap, total_hrs_up columns.
total_hrs_up is the important one, this needs to work out based on the two shift patterns the number of hours that the machine is available and then take off the holiday hours to give a final value.
so current data example in data is
date machine shifts shiftf shift2s shift2f cals, calf, cap, calcap, total_hrs
16-JUL-08     100 09:00:00     17:00:00     12:00:00     00:00:00               '','','',1     ,''
16-JUL-08     105 09:00:00     17:00:00     12:00:00     00:00:00               '','','',1     ,''
16-JUL-08     107 09:00:00     17:00:00     12:00:00     00:00:00               '','','',1     ,''
id like to see based on the holiday table if there is a holiday then this data is updated as such and a total_hrs machine is available populated on that date.
Any help is very much appreciated!
Thanks

Hi,
The following query does what you requested.
It makes the following assumptions:
(a) in data, shift1start <= shift1finish
(b) in holiday, hol_start <= hol_finish
(b) in data, the combination (machine, shift1start) is unique
(c) in holiday, hol_start <= hol_finish
(d) in holiday, rows for the same machine and id never have overlapping dates (including times). For example:
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 07:00:00', '26-DEC-08 09:59:59');
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 09:00:00', '26-DEC-08 09:59:59');will cause a probem. Multiple rows for the same machine and day are okay, however, if the times do not overlap, like the following:
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 07:00:00', '26-DEC-08 08:59:59');
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 09:00:00', '26-DEC-08 09:59:59');Here's the UPDATE statement:
UPDATE     data     m
SET     (     hol_start
     ,     hol_finish
     ,     no_of_available_minutes
     ) =
(     SELECT     MIN (date_from)
     ,     MAX (date_to)
     ,     (     MAX (shift1finish - shift1start)     -- Total from data
          -     ( NVL     ( SUM     ( LEAST (date_to, shift1finish)
                         - GREATEST (date_from, shift1start)
                    , 0
                    )                    -- Total from holiday
               / MAX (total_no_of_machines)          -- Average
          ) * 24 * 60                         -- Convert days to minutes
     FROM          data     d
     LEFT OUTER JOIN     holiday     h     ON     h.machine     = d.machine
                         AND NOT     (     date_from     > shift1finish
                              OR      date_to          < shift1start
     WHERE          d.machine     = m.machine
     AND          d.shift1start     = m.shift1start
);The subquery has to use its own copy of data (that is, in needs d, not m), since the subquery has to return a non-NULL number of minutes when no rows in h match m.

Need help with the session state value items.

I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?

You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Hey damien555,
Thanks for the question, I understand how frustrating this may be. It sounds like the update process may have been interrupted, and to resolve the issue, we’ll need to restore your device in recovery mode with iTunes:

Update multiple columns with single update statement..

HI all,
i am reading the columns value from different table but i want to update it with signle update statement..
such as how to update multiple columns (50 columns) of table with single update statement .. is there any sql statement available i know it how to do with pl/sql..

As I understood, may be this. Here i am updating ename,sal, comm columns all at once.
SQL> select * from emp where empno=7369;
     EMPNO ENAME      JOB              MGR HIREDATE                   SAL       COMM     DEPTNO

Bob

Now we are getting somewhere. Identifier 'PARSE' must be declared.
I again used the 'Search' link just above the forum posts and entered 'dbms_sql.parse' and got a short list of hits (as I suggested in my previous reply).
There is one with Barbara's name on it. It shows exactly how to do what you are trying to do. In particular note her code:
DBMS_SQL.PARSE
(cursor_name,
'UPDATE client SET '
| | v_column
| | ' = ' | | '''' | | v_new_data | | ''''
| | ' WHERE account_id = '
| | v_account_id,
DBMS_SQL.NATIVE);
Compare her PARSE statement to yours and you will see some major differences. The PARSE procedure is defined in the DBMS_SQL package and must be reference by DBMS_SQL.PARSE as Barbara shows.
In addition to dynamic SQL using the DBMS_SQL package Oracle 8i also supports the EXEC IMMEDIATE statement.
All of Oracle's documentation is available online via the 'Documentation' link on the left side of the OTN home page.
The 'Supplied PL/SQL Packages Reference' has a chapter for each package (including DBMS_SQL) and describes the procedures/functions in the package and how to use them.
The 'Application Developers Guide - Fundamentals' has chapters on 'processing SQL statements' and 'dynamic SQL' that go into some detail on performing dynamic sql.
Yes, Barbara's code uses a CURSOR. The DBMS_SQl package requires it and so does your code. Almost all SQL uses a CURSOR either implicitly or explicitly.
My comments are not, and were not, directed at you personally so I hope you don't take them that way.
Your latest reply has a lot of useful information in it.
1. 19/1 PLS-00201: identifier 'PARSE' must be declared. This is the explicit error message we need to help someone. We don't have to guess which error they are talking about. We can look it up in the MESSAGES manual if necessary. When someone says 'I get an error', or 'I get a PARSE error' we can only guess which error they are talking about.
In your reply you state that you looked at Barbara's code, she uses a cursor and you don't need a cursor. That is very useful information to someone trying to help you because it tells us two things: you are trying to find the answer for yourself (a lot of people just want someone to write the code for them) and it shows that you haven't made the connection between Barbara's example (which shows EXACTLY what you need to do) and your own code.
This is a public forum and I have found it useful to keep repeating certain suggestions.
For whatever reason many people still do not seem to realize that:
1. ALL of Oracle's documentation is available on-line via the 'Documentation' link on the left side of the OTN main page.
2. You can purchase (for about $50) a CD-ROM that has all of the Oracle documentation on it in both PDF and HTML format.
3. The 'search' link just above each discussion forum allows one to search any or all forums for topics, users, etc.
The above resources should be used by everyone.
Good luck!

Regex help for SQL update statement

Hello,
need help from IPS regex guru - trying to build the signature to detect SQL update statement in HTTP requests.
1) Am I correct with regex below specified as Request-Regex?
[Uu][Pp][Dd][Aa][Tt][Ee]([%]20|[+])[\x20-\x7e]+[Ss][Ee][Tt]([%]20|[+])[\x20-\x7e]+=
2) How do I make sure that it detects 'Update' in URI and Arguments only and not in the body on entire webserver response (currently looks like the case)?

1) It looks correct to me
2) Typically, the "service HTTP" engine is used to inspect requests and the "TCP string" engine is used to inspect HTTP server responses. If you only want to inspect requests, use the service HTTP engine.

Help with replicating/updating vendor master data

Hi,
Currently, we run the bbp_vendor_sync program to do the replication. It does the job of both bbpgetvd (new vendor creation) and bbpupdvd (update existing vendor).
But the problem is, we have two number ranges for vendors. One is Numeric and other one is Alpha.
Group -->AB     From 0010000000     to 0699999999
Group -->AZ     From A     to ZZZZZZZZZZ
The vendor synchronization program can consider only one number range at a time i.e.
either Numeric or Alpha. So, we have to switch the active number range
and run the program twice., first for numeric and then for alpha.
In order to avoid this, I'm looking at implementing bbp_transdata_prep which I was told would take care of this issue.
I looked around for documentation/sample code for bbp_transdata badi and couldnt find any on SAP help site or SDN.
Wondering if someone can help with the documentation/sample code and difficuly level of implementing this BADI.
Any help would be highly appreciated and suitable points would be awarded for your help.
Also, if there is another way to solve this issue without implementing transdata badi, pls. let me know.
TIA,
Seyed

Sender JDBC: help to construct Update statement

Hi,
I need help in writing a update statement to DB2 database in sender JDBC adapter.
The sender adapter picks up only few records say 10 at a time which match the Select query condition. So I would need to update only those selected "n" records and not all the records that match the Select query condition.
Select looks like :
Select * from <table> where <condition> fetch first <n> rows only.
But it is not allowing the following update
update <table> set <field> = <value> where <field> IN (Select * from <table> where <condition> fetch first <n> rows only)
The above statement errors because DB2 does not allows u201CFetchu201D statement within the update sub query.
Any pointers to a write update statement for n records is highly appreciatedu2026
~SaNvu2026

Hi Santosh,
In JDBC Sender Adapter provide the following select & update statements
Select Statement:
select * from <table> where <condition> AND ROWNUM<N (N==No.of Rows)
Update Statement:
update <table> set <field> = <value> where <field> IN (Select * from <table> where <condition> AND ROWNUM<N)
(N==No.of Rows)
And for the error you are facing is because of the server communication link failure between the two systems.
Check the connections and try to stop & start communication channels once.

Looking for some help with building insert statements...

Hi, I am using some sql to build some insert statements for me to update a set of tables in our qa environments. The scripts that I have created were working great until someone added a column to some of the tables in the qa env which in turn makes my scripts break because I was simply building the statment to do someting like this...
insert into dest_table (select * from source_table@dblink);
But now when the coumns in the tables do not match it breaks...
This is the dynamic create script I use, can anyone help or suggest a better way to be able to build update statements update to qa tables when the columns are mismatched?
spool insert.sql
select
'insert into ' || table_name || ' (select * from ' || table_name || '@prod );' || chr(10) || ' commit;'
from user_tables
where table_name in
(select * from refresh_tablesl)
any help is greatly appreciated,
Thanks.

I've checked that all the data fields are in the correct
format, and I can't see why I am getting a syntax error. Any help
on this would be appriciated

Agreed, but it looks like you already have the sql. Take the
query from the error message above and run it in your database.
Though I did notice have an extra comma between the last column and
there WHERE clause.
wALUinst = 'yes' , WHERE companyid = 33415
For the optional columns, put the commas first to prevent
errors due to trailing or too many commas
UPDATE Table
SET Column1 = 'value'
<cfif SomeValueExists>, Column2 = 'other value'
</cfif>
WHERE ID = 123
Two other things to consider: use cfqueryparam and consider
normalizing your table. Column names like Contact1, Contact2,
Contact3 ... are usually a sign its time to normalize.

Need help with understanding updates, partitions, firmware etc.

I went to update my QuickTime and in doing so was told to update my OS which included QT updates. Now I'm getting all kinds of messages about partitions, firmware etc. do not understand at all what's going on.

THIS IS MY STEP BY STEP situation with my updates:
I go to the Apple Icon and selected Software Update and it reads I have 2 items:
MacBook EFI Firmware Update 1.2
MacBook SMC Firmware Update 1.4
I select Install and then it state Installs completed successfully.
BUT THEN I recieve and new icon and this message below:
To update the SMC firmware on your MacBook:
Your computer's power cord must be connected and plugged into a working power source, or your battery must be at least 25% charged.
For more information see 'http://support.apple.com/kb/TS3499'.
1. Quit all other open applications.
2. Click Restart in the MacBook SMC Firmware Update window and wait for your computer to restart.
The SMC firmware update starts automatically. A status bar indicates the progress of the update. During the update your computer fans will run at full speed, but will return to normal once the update completes.
Important: Do not interrupt the update.
Your computer restarts automatically when the update is completed and opens the MacBook SMC Firmware Update.
3. Click OK. The SMC firmware is now up-to-date.
If these instructions appear on your screen again, the SMC firmware update was not successful. Repeat steps 2 and 3.
I follow the instructions and then I get this: (could get my image to attach but here's what it said)
the first error message heading of:
MacBook SMC Firmware Update 1.4
Your firmware could not be updated, the hard drive partition scheme may not be supported. You must be booted from a GUID partition or RAID scheme.
see http://support.apple.com/kb/HT2434 for more information (internal error 28:3)
THEN ANOTHER ONE POPS UP saying:
Your Hard Drive partition scheme is not supported, you must be booted from a GUID partition scheme.
see http://docs.info.apple.com/article.html? artnum=303609 for more information
I went to those URL and tried to understand what it was telling me but I did not understand. I can't figure, by reading thru forums, etc, if I need to do this or not and what exactly it is.
So back to just pushing a simplet update has thrown all this unknown info. my way and I have no clue what to do.
Thank you. Hope this is more clear.

Help with a update query from a subquery

Hello All,
I wanted to see if someone can help me with an update query.
I need to grab a latitude & longitude from a the same user that is in two accounts. therefore i am trying to update lat/long in a users table for one account based off of the same user in another account. I am matching the users up by phone number and last name. I tried a subquery but am having difficulty.
I was thinking of something like the following:
update users
set lat = getlat, long = getlong
inner join (select lat as getlat, long as get long from users where account_id = '1')
on phone = phone and last name = lastname
where account_id = '2' and lat IS NULL and long IS NULL
Am I going in the right direction???
Thanks in advance for any assistance!!!!

What difficulty are you having? Have you tried what you posted and get an error?
Although someone may be able to give you sql advice here, I would try posting this over at Stack Overflow as its not really related to Coldfusion.
