I want to be master in Pl/sql

Hi..
I have good knowledge in plsql theoretically but not practically... i working on plsql from 6 months but still some times i am facing problems in logical thinking..
So can anybody tell me to improve..

Want to add a few pence to what Blue said...
A "master programming" is good in any language. You can know the ins and outs of a language to the finest degree - amaze your peers with being able not only recall every single command in the language, but also quote all its parameters, including optional ones.
And you can still be a poor programmer.
It is not about knowing the language, It is about knowing programming. Programming logic. Programming design. Modularisation.
It is about knowing what a control break is. It is about knowing not only what the statement you've coded does, but knowing WHY it is sitting there in that line of the code. Why that command? Why there in the code and not somewhere else?
And the only way you get good at this is to write code.. and write code.. and write code. Year after year after year...

I want to use the SQL Toolkit of NI and SQL Server as my databasis on a server. Do I need to install a client in each computer I want to handle the data into SQL tables or I need only a ODBC driver?

I want to use the SQL Toolkit of NI and SQL Server as my databasis on a server. Do I need to install a client in each computer I want to handle the data into SQL tables or I need only a ODBC driver?

You only need the ODBC driver on each computer. If you are distributing the SQL Toolkit app as an executable and do not install the whole toolkit on each computer, you'll need the SQL Toolkit support files. This is about a dozen files. You can get the list at http://digital.ni.com/public.nsf/websearch/b814be005f9da9258625658700550c75?OpenDocument.

I want to allocate balance qty in sql.....

Please help me…
I want to allocate balance qty in sql.....
I have data like below table and expected answer in column EDIT_UP_TO_EXEPECTED_ANS.
I want to edit data with validation of next process executed qty.
for example in row 3rd and 4th PROCESS_EXECUTE_QTY is ORDER_VRNO wise is 100 i.e.
100+0=100 and i want to allocated this qty in 1st and 2nd row i.e. 75,25 i.e. 75+25=100
because first process CUTTING of jobcard_no J113Y-1004 is 75 and next process done is 100 order_vrno wise
so i want to allocated 100 in 75,100 i.e. 75,25 total should be next process execute qty i.e. 100

i want to query oracle database from sql server can anyone tell steps 2 followed
i tried with linked servers but it is throwing errors can anyone hepl in this regard
The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction.
OLE DB error trace [OLE/DB Provider 'MSDAORA' ITransactionJoin::JoinTransaction returned 0x8004d01b].

First of all - you are in the wrong forum.
Look either for the Database general or search for Transparant / Heterogenous Gateways.

I don't have intimate knowledge of SQL Server, but to me, your code seems reasonable. I guess there is some "fine point" (a bug?) to using self referenceing foreign keys in SQL Server. It doesn't seem plausible that the error originates with the driver, unless it's a very intelligent kind of driver.
A "Gordian Knot" kind of solution to your problem is to ask whether you really need the foreign key constraint in the db schema. Is the table used by something other than your EJB? Anyway, putting logic responsible for the correct functioning of your EJB into the db schema is often a bad practice, as it makes the code harder to understand, maintain, port etc.

Master Detail dynamic sql

Hello,
I have a master table and detail table (1-n relation) like:
MASTER_TABLE(ID, FILTER_COLUMN1, FILTER_COLUMN2, FILTER_COLUMN_3); //ID is primary key
DETAIL_TABLE (ID, MASTER_ID, OTHER_COLUMN1, OTHER_COLUMN2); // ID is primary key, MASTER_ID is foreign key.
I want to write a stored procedure which takes 3 input parameters to be used to filter MASTER table.
These input parameters can be null or not null. And I want two REF CURSOR as OUT parameters.
The stored procedure is like;
TYPE T_CURSOR IS REF CURSOR;
PROCEDURE SP_GET_TAX_OFFICES(
PI_FILTER_COLUMN1 IN MASTER_TABLE.FILTER_COLUMN1%TYPE,
PI_FILTER_COLUMN2 IN MASTER_TABLE.FILTER_COLUMN2%TYPE,
PI_FILTER_COLUMN3 IN MASTER_TABLE.FILTER_COLUMN3%TYPE,
CUR_MASTER OUT T_CURSOR,
     CUR_DETAIL OUT T_CURSOR
I wrote a dynamic sql like
     master_query := 'select M.* from MASTER TABLE M WHERE 1=1 ';
IF ((PI_FILTER_COLUMN1 is not null) AND (PI_FILTER_COLUMN1 > 0)) THEN
dynamic_query := dynamic_query || ' AND M.FILTER_COLUMN1 = :1';
ELSE
dynamic_query := dynamic_query || ' AND (1 = 1 or :1 is null)';
END IF;
     IF ((PI_FILTER_COLUMN2 is not null) AND (PI_FILTER_COLUMN2 > 0)) THEN
dynamic_query := dynamic_query || ' AND M.FILTER_COLUMN2 = :2';
ELSE
dynamic_query := dynamic_query || ' AND (1 = 1 or :2 is null)';
END IF;
     IF ((PI_FILTER_COLUMN3 is not null) AND (PI_FILTER_COLUMN3 > 0)) THEN
dynamic_query := dynamic_query || ' AND M.FILTER_COLUMN3 = :3';
ELSE
dynamic_query := dynamic_query || ' AND (1 = 1 or :3 is null)';
END IF;
     OPEN CUR_MASTER FOR master_query
               USING PI_FILTER_COLUMN1, PI_FILTER_COLUMN2, PI_FILTER_COLUMN3;
with above I can get the filtered MASTER_TABLE records,
but what I also want is getting those filtered MASTER_TABLE records's child records as CUR_DETAIL.
Any help is greatly appreciated. I am sure there is some clever methods to do this.
Edited by: user10133948 on Oct 12, 2010 8:19 AM

can you just lose the dynamic sql stuff and add the variable checks to your select?
not sure what you are after but something like
SELECT M.*
FROM MASTER TABLE
WHERE (
                 (TAX_OFFICE_NO = p_TAX_OFFICE_NO AND PI_FILTER_COLUMN1 > 0)
                   OR
                   NVL (PI_FILTER_COLUMN1, 0) <= 0
       AND
                 (FILTER_COLUMN2 = p_FILTER_COLUMN2 AND p_FILTER_COLUMN2 > 0)
                   OR NVL (PI_FILTER_COLUMN2, 0) <= 0
      and ......Edited by: pollywog on Oct 12, 2010 10:50 AM

Error Message while adding Item in Item Master Data- [Microsoft][SQL Server Native Client 10.0][SQL Server]Conversion failed when converting the nvarchar value 's008 01' to data type int. (CINF)

Dear Experts
I am getting the following error message while adding item in Item Master data. I have modified the following SBO_SP_transactionNotification in SQL server after that could not able to add the item

   BEGIN
    SELECT @ERROR=1,@ERROR_MESSAGE='Please insert the price !'
END
end
-- Select the return values
select @error, @error_message
end

Hi Rathna,
Just put the SP like this, without the -- before the IF. A -- marks the line as a command therefore you need to uncomment and it will work.
IF @OBJECT_TYPE = '59' AND (@TRANSACTION_TYPE = 'A' or @TRANSACTION_TYPE = 'U')
BEGIN
   IF EXISTS(
    SELECT T0.Price FROM IGN1 T0
    where IsNull(T0.Price, '0') = '0' and T0.DocEntry = @list_of_cols_val_tab_del)
   BEGIN
    SELECT @ERROR=1,@ERROR_MESSAGE='Please insert the price !'
END
end
Hope it helps

I want to use master password but sites I had previously said not save passwords are not listed in the security section of tools/options. What do I do?

I was not using the master password provision but have decided to. There are a number of sited where I told Firefox not to save the password. I have since changed my mind and want to use the master password. There are no sites listed as exceptions in the options/tools/remember passwords for sites/exceptions.
How do I get Firefox to remember passwords for sites I had previously to it not to remember?

If it is not in the exceptions list you should be able to go to that site again and type in password and it will ask you if you want to save it.
More about it here.

1) We click on any record on department block.
2) Then we change / insert /delete record in employee block.
3) then we move to anothe department.
4) now it ask for saving the changes. THIS WE DO NOT WANT.
5) WE WANT TO SAVE CHANGES WHEN USER CLICK ON SAVE BUTTON.
6) If user make changes to various employees of various department,
we want user to cancel changes when ever user wants.
IN SHORT WHAT WE WANT IS
No record should be saved untill user press save button below.
and If user press cancel all changes made must be undo.
PLEASE DO NOT SUGGEST DO_COMMIT in clear block details,
We know that and we dont want that option.
