I have an application connected to Oracle 11g that sends its own querys to the db based on what the user is clickng on. The applicaiton is connected via one user id and I was wondering, is there a way that I can capture the tiem each query starts, the sql itself, and the amount of time it took to fetch the data?

There are several stages for sql processing in 10g2 database concept document.The following stages are necessary for each type of statement processing:
■ Stage 1: Create a Cursor
■ Stage 2: Parse the Statement
■ Stage 5: Bind Any Variables
■ Stage 7: Run the Statement
■ Stage 9: Close the Cursor
Optionally, you can include another stage:
■ Stage 6: Parallelize the Statement
Queries (SELECTs) require several additional stages, as shown in Figure 241:
■ Stage 3: Describe Results of a Query
■ Stage 4: Define Output of a Query
■ Stage 8: Fetch Rows of a Query
Stage 3: Describe Results of a Query The describe stage is necessary only if the characteristics of a query's result are not known; for example, when a query is entered interactively by a user. In this case, the describe stage determines the characteristics (datatypes, lengths, and names) of a query's result.
Stage 4: Define Output of a Query In the define stage for queries, you specify the location, size, and datatype of variables defined to receive each fetched value. These variables are called define variables. Oracle performs datatype conversion if necessary.
I still don't understand what's Stage 3: Describe Results of a Query and Stage 4: Define Output of a Query.
after running some TPC-C performance benchmarks on oracle 11g/r2 the following results for average transaction time vs user load were found:
Userload 1 : 60ms
Userload 2 : 55ms
Userload 3 : 25ms
Userload 4 : 25ms
Surely these should be the other way wound, transaction time increasing as the number of users does?
what may have caused this? or are the user loads too small to be representative
I'd like to know if it is possible to track DML actions issued on a specific table by a specific user, for example , i tried :
AUDIT SELECT on SCOTT.DEPT by HR by ACCESS;
I get an error, where is my syntax error ?
i want to know if it's possible to do it without trigger ?
i cant find any oracle specific methods for chunking data -if i had returned rows of numbers, how could i chunk them into ranges?
View 2 Replies View RelatedI have one inline view query which shows exec\ fetch : 2 sec\ 19 sec It gives 500 rows as final out put, when i give rownum<100 it shows exec\ fetch : 1 sec\ 000 sec, and i cannot use this rownum< 100 alternative as this is inline subquery of big query.
What does this exec and Fetch time is?
How to improve fetch time, (esp with sub-query) ?
I am currently doing a project where i need to write a stored procedure which will be doing the following-
i)it will retrieve multiple columns from multiple tables in a single database(through join) based on certain conditions
II)then it will store the entire data in a certain field(File_data) of staging table
inside file_data a header and a trailer will be present with the records.also the field values will be pipe separated and a new record will start in a new line.
So,the data inside the file_data of staging table will look like this-
H|v1000
transdate|ordnmb|deposite_amt|order_status....
12-nov-09|123456|23.8|C...
4-dec-07|234567|67.7|R...
..........
7-jan-04|567890|54.7|x.....
T|234(record count)
i did this formatting using java, but my project leader wants me to do the formatting using SP,and wants me to use staging table.
creating Oracle SQL query to fetch the information using PIVOT option.We are populating audit table using triggers. For every update, there will be two rows into audit table, one row with all OLD values and another with all NEW values. Also every updated is uniquely identified by Sequence No. Example for phone audit is mentioned below :
CREATE TABLE test_audit_phone
(
emplid VARCHAR2(10),
seqno NUMBER,
action VARCHAR2(3),
office NUMBER,
mobile NUMBER
);
Insert some rows into table.
INSERT INTO test_audit_phone VALUES ('100',1,'OLD',1111,9999)
/
INSERT INTO test_audit_phone VALUES ('100',1,'NEW',2222,9999)
/
INSERT INTO test_audit_phone VALUES ('100',2,'OLD',2222,9999)
/
INSERT INTO test_audit_phone VALUES ('100',2,'NEW',2222,8888)
/
Table will look like the following :
SQL> SELECT * FROM sysadm.test_audit_phone ;
EMPLID SEQNO ACT OFFICE MOBILE
---------- ---------- --- ---------- ----------
100 1 OLD 1111 9999
100 1 NEW 2222 9999
100 2 OLD 2222 9999
100 2 NEW 2222 8888
Now we have to present data in different format. For each field, display OLD and NEW values in column format.
EMPLIDFIELDOLDNEW
----- ------ ---- -----
100OFFICE11112222
100MOBILE99998888
Challenges :
1) Make pivoting with old and new values
2) For each field we have to show old and new values
3)if old and new values are same, dont show in report.

i create form in which first block is non database having 2 items from_date and to_date and one button is there.when i click on button i.e when button pressed new window is open having new database block

my problem is that when i click on button i fetch only one record
i want to fetch records of emp whose hiredate between 1 sep to 30 sep of any year. i am using the below query but it show me wrong results.
select * from tran where to_char(timestamp,'DD-MM') between '01-SEP' and '30-SEP'
I am using toad to output the details of the database. (I need these details in a format which i can then import into excel) However, When I run sporadic individual records through my query, the results come back correct and as expected. But when I run the full data set through my query a lot of the records have different values than what they do when run individually!
Ive spent all day on this script and its really a hack of various other cursors and scripts brought together. Its driving me mad as my code doesn't seem to be wrong (since the results are correct when a single record is run) yet there must be something wrong as my full data set does not return correctly!
i want to fetch the data in my form from table, by using item_code.
eg when i write the item_code its value get matched in same table and fetch the another
columns by item_code.
I have a form on a table that allows me to edit, delete, or create records. If I choose to edit a record from the report the form get populated correctly and edits or deletes work fine. My problem is when I choose to create a new record. I get a blank form which is what I want, but once I fill it out and click the create button, the automated row fetch fires again and gives me a no data found error. How do I get it to not fire when the create button is pressed?

I've got a query running a select count (*) over a table. The default plan takes in the order of 15 minutes to return, a hinted plan to use a different index takes 3 minutes to return.
Unfortunately I cant get at the index stats and a few other areas which I suspect may be key here.When running autotrace against the two queries I see fairly different values as one would expect.
Query
select count (*) from fulfilmentitem bfi where created >= sysdate-30 AND bfi.status = 'FA' AND bfi.fulfilmentmethod = 'D'
Slow run
PLAN_TABLE_OUTPUT
-----------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)|
----------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | 1 | 15 | 33119 (1)|
| 1 | SORT AGGREGATE | | 1 | 15 | |
|* 2 | TABLE ACCESS BY INDEX ROWID| FULFILMENTITEM | 12525 | 183K| 33119 (1)|
|* 3 | INDEX RANGE SCAN | IDX_FULFIL_METHODSTATUS | 250K| | 1786 (1)|
----------------------------------------------------------------------------------------------
[code]....
IDX_FULFIL_METHODSTATUS is across FULFILMENTMETHOD & STATUS in that order.
IDX_BFI_CREATED is on CREATED and is approx 70% of the size of the other index
The row counts estimated in the explain plan are out, the count(*) comes in at 32.8k rows.As you will have seen, the fast run shows a pretty significant consistent get increase compared to the slow run and a decent though not dramatic physical read drop.
My uncertainty is around if these changes in consistent get/phys read values would typically be enough to suggest the real time improvements I'm observing or if other (albeit perhaps temporary) factors are involved. It is a prod OLTP environment so the data will be rapidly changing and that may be a factor.
I know it can never be an exact science without intimately knowing the hardware/current loads etc but I also know that there's enough experience on these boards to have a loose handle on if the time shifts between queries are likely (or not) to be reflective of the stat changes or if those differences alone shouldn't (or typically wouldn't account) for it.
I'm thinking about instructing the query to ignore its original plan but am hesitant to do so without being a little more confident that it's not just a timing thing or something other than the change of index approach which may be causing the improvement. the autotrace stat changes observed I couldn't put my hand on heart say "yup - that change is good, ignore the default index all the time for this job".
