what executable statements in PL/SQL mean? My objectives are:
1)Writing Executable Statements
2)Create PL/SQL executable blocks using DML and transaction control
I have to explain what exactly each is and what should come under it. what kind of statements and what should be covered under executable statements?
I have created two non base table text items(from date, to date) and if values are not entered from front end i.e. null then hadrcoded in pre_query trigger to default values.But even i enter values dynamically from front end and when ever i press fetch button ,it is taking default values i.e. it is not accepting values what i have entered.
View 6 Replies View RelatedI am working on form builder 6i. I have a header block A(Multi record block), child block B. Both are non control blocks. My requirement is, if i put the cursor in any header record, i want to auto populate corresponding child record like in master child relation.
which trigger i need to write logic to auto populate the child record.
1)How a single control file is enough to have all the transaction's SCN no for older transactions.
Eg - A transaction has the SCN 01 and after a month the new transaction's SCN is 502. Is the control file holding all those (01 to 502) SCN in it or just will have the latest SCN no (ie - 502).
[save] button can be done but how to handle [cancel] button
Master record
Transaction record 1
Transaction record 2
Transaction record 3the user does one/all of the following changes
Master record
Transaction record 1 : deleted
Transaction record 2
Transaction record 3 :edited
Transaction record 4 :new added
now the Requirement is :
when the user hits [ save ] all the records are saved
with in *new master record ID*
else
when the user hits [ ignore/cancel ] all the *Actions on transaction is rolledback*

If I look at the unformatted blocks its zero, which tells me that data is being placed into every block (pretty well compressed). But what I don't understand is why there are 102,936 blocks that are only 25-50% full? I would have expected to see some blocks that in the75%-100% full range as this index was recently dropped and rebuilt 2 months ago.
This index is on a partitioned tabled, where the 90th day and higher partitions are dropped daily.
Here is the layout of the index
CREATE INDEX T1.FEAT_IDX ON T1.FEAT

can i have more than one pl sql blocks in a function and can i use the variable of one cursor into another cursor of the same function?
View 2 Replies View RelatedI have a block of code that looks something like this, I'll write it in pseudo code to avoid pasting 100's of lines of
IF <condition> THEN
FOR record in (select query here..)
LOOP
--add data
END LOOP
END IF;
IF <condition> THEN
--do soemthing
END IF;
IF <condiiton> THEN
--do soemthing
END IF;
Now, in the 1st IF statement there is a for loop which basically builds up a tab type array - this takes at least an hour to execute based on the select query which returns 1000's of records.
The strange thing is, that my log files shows that at the time the procedure was executed, the stuff in the 2nd IF statement was executed almost straight away.. is this even possible?
If the loop in the 1st IF statement takes over an hour to finish, how is it possible for the 2nd IF statement stuff to process straight away? My log files show me that the loop in the 1st IF statement was going on for a good hour.. yet the 2nd IF statement was executed straight away.
If in a PlSQL procedures there are many DML statements which are part of the same transaction. and there are many calls to other PLSQL blocks also.
what is the best practice to use commit either after each DML statement or to use it in the End of Block?
I am interested about the fast way to access all data in physical block. what is the quick way to bring data blocks using the rowid, I found this script but soon as I can have faster access:
select * from table_name t
WHERE ROWID between 'AAAUaOAAEAAHkJiAAA' and 'AAAUaOAAEAAHkJiAA8';
where 'AAAUaOAAEAAHkJiAAA' is the last element in the block and 'AAAUaOAAEAAHkJiAA8' is the first one
my question is can retrieve all the data in one block more quick than this query.
DB: Oracle 10g R2
OS: SUSE Linux SP 1 x864
We are maintaining a DR of our Database Server(oracle 10g R2 atop SUSE SP1 Linux) using Platespin(
[URL]......
Platespin is set to replicate(block based), incremental data(delta) every 1.5 hour from Production to DR site over a 30 Mbps dedicated fiber link.
Our maximum changes of data per day(during business hours) wont exceed 300 MB. During business hours Platespin replicates at least 1 GB at every replication cycle, while during off hours it replicates 300 to 500 MB per replication cycle. We are facing this strange issue with this box only(SLES 10 SP1 + Oracle 10g R2), we have protected MS Exchange 2007 Server based workloads without this strange issue, i.e in case of Exchange only delta replicates from Production server to DR site on Platespin.
Platespin support says us that Oracle re-indexes its database for better performance, so it is possible that re-indexing causes the blocks level changes on the storage, and since Platespin works on Block level, thats why it replicates so much(even though data is not changed that much)
here is actual words of Platespin support
<snip>
I think whenever Oracle database Indexing happens, it changes almost most of the Blocks of database and Platespin replicate all those Blocks.
As you know, Platespin checks the Date/Time attribute of every blocks before replication and if Date/Time attribute changes from last replication, it considers as changed block and replicate those blocks on Platespin Appliance. So, my suggestion is just look into the Oracle server behaviour before/after Data indexing process and do needful or do some workaround to overcome this issue.

is there anything we can do at oracle level ?
I have a written a script which doesnt take any parameter. this is an anonymous block. I run my script as below: SQL> @filename.sql
I would like to convert this into a procedure which should be called in an anonymous block. run a procedure from an anonymous block.
I would also like to know how to run the same from the SQL prompt.
find the below table. The entire data is within DOCSTART and DOCEND. The data is further enclosed within BACCSTART and BACCEND. This type of block is repeatable. I have to pick up any of ABCD which is also repeatable and TOTAL(occurring once per block) and ACCNAME (occurring once per block) for each block within BACCSTART and BACCEND and form an xml like
<BACCSTART>
<TOTAL>100</TOTAL>
<ABCD>abcd</ABCD>
<ACCNAME>name</ACCNAME>
</BACCSTART>
for each such block. Presently I am using a for loop, but the performance is not up to the mark. It will have around 200 such blocks for which I have to form the xmls within 15 seconds. Presently the for loop is taking around 53 secs.
ROWNUM NAME VALUE
1 DOCSTART null
2 BACCSTART null

what empty blocks are, and how to remove them.What I'd like to do is not have empty blocks in the first place on loading a table. I load a lot of "static" tables and would like to not have any wasted space at the end, with minimal shinanigans.
I've set pctfree 0
I"ve set initial to close to the end table size
I've set next to 1M
I've set pctincrease 0
blocksize is 8k
Yet I still need to at least do an alter table deallocate unused
I have two blocks, both are multi record block. 1st block is control block and second is database block. Both the blocks have same fields(Example: Location,Location_name,Location_Type). In the first block(Control Block) I have check box. My goal is when I check the checkbox and click on add button all the records which are selected in first block should go to second block.

I came to know that there may be contention on data blocks, which may be a prime reason for degraded performance. Herewith i'm pasting my actual stats of gathered from v$waitstat. I gone through some of asktom docs and find that there may be a problem with freelist or segment space management. My data tablespace is segment space management = Manual.

i am using form6i & oracle 8i.
i have master -detail form. both are database blocks.
i have inserted values for the master block bt not for the detail record my problem is.. "user should not be allowed" to move to next record of the master block before saving the current record
We are having two data blocks as Earnings and Deductions. We need to export this to an excel in single sheet parallel [ imagine your payslip format ].
if we use normal text_io we are not able to get the result we want. so we have tried using a package called export2excel. we achieved what we want. The form is working perfectly in client server concept. When we move the same form to our Unix application server, it is not working.
I have this error. To put it simply I have two blocks.
Block1 contains two drop down list with PL/SQL statements for queries.
Block2 contains tabular form created from block wizard (I tried already in manual)
that will catch the result in Block1 queries.
Now I have a button with a trigger when-button-pressed that contains
BEGIN
INSERT INTO dummy1
VALUES ('hello',1,2,3);
COMMIT;
END;
My goal is to add into dummy1 values from :block2.item_name1, :block2.item_name2, :block2.item_name3 but to put it simply I tried these values but I received the same error.
When I run it and first things first click the button, the values will be added into dummy1 table but when I execute the block1 - dropdown list queries and try to press the button. I received the error.
I HAVE 2 BLOCKS E.G. MASTER-DETAIL AND i have created it manually then how to insert values thrugh these blocks using a button called "save" using "commit_form;" suppose form fields are
master-block:
emp_id
emp name
age
detail block:
address
city
where emp_id is primary key as well foreign key in detail table
how these values will be inserted in both tables
I have 4 blocks in my form which is basically used for travel booking for the employees in a company within India
1) Header block :- contains info abt the person who is booking the tickets for number of employees. Here i have given booking no a primary key.
2) Employee Detail :- Here the basic info of an employee is entered. Here i have taken booking number as a foreign key and then given emp_cd & booking number as a composite primary key.
3) Travel Detail :- Here the travel detail of individual employee will be entered wherein a unique trv_no will b generated 4 every single travel. Again i have taken foreign key as bkng_no frm 1st blck and emp_cd frm 2nd blck and tkn a composite primary key which comprises of bk_no,emp_cd and trv_no. this is used to maintain the uniqueness for single travel.
4) Vehicle Hotel Details :- This block is placed on different canvas for same form.It is meant for Other details in which details regarding hotel,vehicle etc booking aftr reaching the destination is entered. In this block thrs no primary key, but i hv taken the composite primary key of 3rd block as a foreign key since thr will be multiple entries for this one entire travel.
At every level there will be multiple entries for each corresponding entered record. I am able to enter one single record properly i.e. for 1 emp i am able to enter multiple travel details and his other requirements but asi try to enter more then one employee info, his travel details, other requirements i face an error stating foreign key constraint violated.Parent key not found for 3 rd level block.
How can i get the desired o/p wherein all the multiple records for every single subsequent record are stored correctly taking all the constraints in to consideration.
I am testing nested blocks, but my logic is apparently not correct.
I am running this script:
DECLARE
v_one number(1) := 1;
v_two number(1) := 2;
[Code]....
I receive the output from only one of the nested blocks:
bad
PL/SQL procedure successfully completed.
SQL>
I understand that I don't need nested blocks for the example above, but this was just a condensed version of what I'm trying to do. I think nesting blocks will be easier to read and maintain, instead of having a huge CASE statement.
How can I execute only the nested block for which the condition is true and ignore the nested blocks that follow?
Are nested blocks not the correct answer here? Should I be looking at invoking procedures/functions instead?

if i killed the SID - 1226, then those temp blocks ( 18176 blocks ) will be released and can other session use that space further ?
there is one more column - SEGBLK#
explain what is the exact meaning of this column ?
to reclaim the space, should i issue below command -
