I need to use funtion optional parameters to construct an update statement in the funtion body. I have two scenarios, either both parameters are not null or the 2nd is null. Do I have to use
IF
(param2 is null)
THEN
udpate using param1 only
ELSE
update using both param1 and param2
END IF;
or is there a shortcut to do this?
I have created a simple function in database that take 2 arguments, the last one is optional.
Now i call the function in Forms 6i PL/SQL Trigger and omitt the default (optional) parameter the form builder crashes when i compile the form (CTRL + SHIFT + K)
i have tried to used both words "DEFAULT" and ":=" in the function's signature for making an optional argument.
Can we call one or more parameters inside a stored procedure call (like func_get_args in PHP) ? Example :
create or replace PROCEDURE test_proc (
val1 in varchar DEFAULT NULL,
val2 in varchar DEFAULT NULL,
val3 in varchar DEFAULT NULL,
[code]..........
I have a procedure that has a number of "optional" parameters.
procedure get_files(
file_name_in in varchar2 default 'dummy_file',
layout_in in number default 1,
client_in in number default null,
data_supplier_in in number default 99999
);
This procedure can be called with any combination of the input parameters.I can set up program(s) using the DBMS_SCHEDULER.CREATE_PROGRAM procedure using a program_type => 'PLSQL_BLOCK' like this:
begin
sys.dbms_scheduler.create_program(
program_name => 'GET_MY_FILES',
program_action => '
declare
begin
get_files( layout_in => 11111, client_in => 2222 );
end ;',
program_type => 'PLSQL_BLOCK',
number_of_arguments => 0);
end;
My question is: Can I set up programs(s) using the DBMS_SCHEDULER.CREATE_PROGRAM procedure using a program_type => 'STORED_PROCEDURE' when I have "optional" parameters? It appears that ALL of the program input parameters must be defined and there is no way to indicate that a parameters is "optional".
Just to let you know this new section in SQL*Plus FAQ wiki page: How to have optional parameters and default values in SQL*Plus_script.

How do I write the select statement ? I think it has to be executed in an anonymous PLSQL Procedure (after submit).
What is a convenient way to write the select statement ? I could imagine to use lots of IF , ELSIF, ELSE statements and in each branch (here 12 ) the whole/complet SELECT statement is written.
How to solve this problem in an elegant way ? In my opinion the CASE statement could be useful, but how to use it in the WHERE clause with this nested conditions ?

This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.

How to update above values with single update query.
I am trying to put transactions into 3 different "buckets" for each month of the year.
I am trying to figure out if the syntax for the "else" part of this code is correct... this will basically appear 12 times for each month of the year changing the value for month:
case when floor(sum(total_adjusted_net_amount)/100) < 0 and month in (01) then 0
when floor(sum(total_adjusted_net_amount)/100) > 29 and month in (01) and then 30
else when floor(sum(total_adjusted_net_amount)/100) and month in (01) end Groupin_01
I have an issue with rather complicated function.Basically it is using DBMS_SQL to execute a very long statement with many parameters (~6000 of them) and binding them with DBMS_SQL.BIND_VARIABLE. Variables are called :1,:2,...,:6000.
When this arguments set is too large - I am receiving error "ORA-00939: too many arguments for function".
Currently I am thinking about dividing the query into subqueries and executing them all with performance decrease.

I have to check some parameter values for an OID tuning I do not have sys access, I have only schema user access
Now how do I see the values of SGA_TARGET, db_cache_size etc parameter
I manage to see these var in init.ora file under /dbs folder but there are 2-3 spfile also having containing these attributes, not sure which reflect the actual.
Also can I alter also these value via schema user or do I need SYS access?
when setting up data guard, if the primary clustered database is already in archive log mode, is there a need to restart both cluster instances when we update the spfile parameters for data guard ? or we can simply add the data guard parameters to the spfile while both cluster instances are online ?

While updating a table, is it possible to get the old value of a column. I need to get it inside a PLSQL block and not in a trigger.for example :-
DECLARE
l_amountNUMBER(5) := 0;
BEGIN
UPDATECustTransactions
SETamount = 150
WHEREcust_id = 5412
RETURNING amount INTO l_amount;
DBMS_OUTPUT.PUT_LINE ( 'l_amount= ' || l_amount );
END;
By using the RETURNING clause i am getting the new updated value. I need the old value for some processing. Do i have to explicitly query it before the update stmt? Pls reply.
I am having trouble figuring out why an update statment is ignoring the primary kiy index when performing an update through the application. The index IS used when the update is run from sql*plus or other sql tools.
The statement is very simple:
update ITEM_MASTER set COST = :1 where SMARTPART_NUM = :2;
ITEM_MASTER has unique, primary key index on SMARTPART_NUM
When I use OEM and other tools, I can see the index is not used in the exlain plan, and the query has a high CPU cost due to the full table scan. The table is analyzed, lately using 100%. Table rowcount is 229768
SELECT column_name, num_distinct, num_buckets, histogram, trunc(last_analyzed) ANALYZED FROM USER_TAB_COL_STATISTICS
WHERE table_name = 'ITEM_MASTER' AND column_name = 'SMARTPART_NUM';
COLUMN_NAME NUM_DISTINCT NUM_BUCKETS HISTOGRAM ANALYZED
------------------------------ ------------ ----------- --------------- ---------
SMARTPART_NUM 198417 254 HEIGHT BALANCED 25-NOV-12
The database is Oracle Database 10g Release 10.2.0.4.0 - 64bit Production (on Windows, standard edition)
Here are parameters related to optimizer:
optimizer_dynamic_sampling integer 2
optimizer_features_enable string 10.2.0.4
optimizer_index_caching integer 0
optimizer_index_cost_adj integer 100
optimizer_mode string ALL_ROWS
optimizer_secure_view_merging boolean TRUE
We've tried rebuilding the indexes then re-analyzing, dropping stats and locking at zero, using various sample sizes; none have any impact.
We wondered if the bind variables are causing this, though in testing outside the application, we tried pl/sql and sql batches to mimic the passing of values into the binds, and all still used the index.
Other than putting a hint into SQL in the application (we'd have to ask for a customization), how can I "fix" the database to use the index? In other words, how can I make the database see that the cost of a FTS is much higher than using the index, whenever it sees these updates (either from sql or the application)? This is the simplest example, but we have 4-5 SQL updates on this and other tables that are ignoring the indexes and using full table scans, so we'd like to fix it for all.
Using Oracle 11gr2. If I call the following update statement from session A, session A will lock the row until a commit/rollback statement is issued from session A. If session B calls the same update statement and same row, session B will have to wait until the lock is released in session A. However, the application developers are speaking in terms of threads. Could it be possible that the update statement is called within the same session by multiple requests? If yes, could the case statement be evaluated without the row being locked which could lead to false results? Trying to keep this post brief. tableA has columnA (primary key, number) and columnB (number)
{update tableAset columnB = case when columnB = 3 then 4 when columnB = 4 then 5 else columnB endwhere columnA = 6;}
Could 2 requests (almost at the exact same time) in the same session evaluate columnB as 3. The desired result would be the first request sets the column to 4 and the second request sets the column to 5.
How to right justify and zero fill in oracle ?
as example input data is '1' and i want to insert '0' in front of the input data and the output will be 01 .
I have a table with 200k entries, which has ~12k unique combination of columns that I wish to assign an ID to. My real world problem is with addresses and street components (of which nulls are allowed); but this should be a reasonable example.
DROP TABLE tt;
CREATE TABLE tt AS
SELECT ROWNUM id,
CASE
WHEN MOD(ROWNUM, 107) = 0 THEN NULL
ELSE MOD(ROWNUM, 101)
END
c1,
CASE
[Code]...
Now I have 3 ways to assigned an ID (fill the SID column).
The first is congruent with the method most commonly used, but seems especially slow in this case. I think this is due to the COALESCE/TO_CHAR usage. Can this be optimized?
DECLARE
CURSOR c1 IS
SELECT a.*, sid_seq.NEXTVAL sid
FROM (SELECT DISTINCT c1, c2 FROM tt) a;
BEGIN
FOR s IN c1 LOOP
UPDATE tt d
[Code]...
The second I've made relies on the usage of a temp table, which I really don't like, but it is faster; so that is something at least.
CREATE TABLE ttt AS
SELECT a.*, sid_seq.NEXTVAL sid
FROM (SELECT DISTINCT c1, c2 FROM tt) a;
[Code]...
The third discards the sequence, and uses dense_rank. This allows us to use the ID (which might have an index, whereas c1 and c2 will not).
MERGE INTO tt d
USING (SELECT id, (SELECT COALESCE(MAX(sid), 317) FROM tt) + DENSE_RANK() OVER (ORDER BY c1, c2) sid FROM tt) s
ON (d.id = s.id)
WHEN MATCHED THEN
UPDATE SET d.sid = s.sid
The ideal solution would use the SEQUENCE, not use a temporary table and match/merge/update based on ID, and be 'fast'; but I cannot conceive of such a solution; does one exist? What would you do?
I have a table called test_renames that has two columns(new_name and old_name) and one row with the following values
NEW_NAME OLD_NAME
DRUG10 DRUG1
I have another table called SH0 that has 10,000 rows and the column of interest is called ITEM1. ITEM 1 contains the following distinct drug names:
DRUG1,DRUG2,DRUG3,DRUG4,DRUG5
Each DRUG has multiple rows associated with it.
I need to only update rows for DRUG1 and set the name from DRUG1 to DRUG10 for all rows where ITEM1 is DRUG1.
However I need to write this update statement by joining with the values in the test_renames table that contains the NEW_NAME and the OLD_NAME.
DRUG1 has 2,000 rows associated with it. The following SQL statement gives me 2,000 rows
(SELECT NVL(CHG.NEW_NAME, SH.ITEM1)
FROM test_renames CHG,sh0 sh
WHERE UPPER(SH.ITEM1) = UPPER(CHG.OLD_NAME)
AND UPPER(SH.ITEM1) IN (SELECT UPPER(OLD_NAME) from test_renames))
However when I run the following update statement, it appears that the SQL query updates all the 10,000 rows in the table instead of just touching the 2,000 rows for DRUG1. It does change all the rows for DRUG1 to DRUG10, but all the other ITEM1 values become null. What I need from the update statement is only chnage the rows for DRUG1 to DRUG10 and leave the other rows that I associated with DRUG2, DRUG3 etc. Here is my update statement.
UPDATE SH0 SH
SET ITEM1 = (SELECT NVL(CHG.NEW_NAME, SH.ITEM1)
FROM test_renames CHG
WHERE UPPER(SH.ITEM1) = UPPER(CHG.OLD_NAME)
AND UPPER(SH.ITEM1) IN (SELECT UPPER(OLD_NAME) from test_renames))
This update statement touches all 10,000 rows. I am looking to update only the relevant 2,000 rows for DRUG1.
I try to apply update statement on the button for the specific records, the command does executes if in the end i write execute_query it always asks for do u wanna save the records, yes or no. I want to remove that message. Also if i write commit it does remove that message but everytime i press the button it updates the old record fine but also adds one more entry for the same record.

My update should either add the total number of inserts per item into the TEMP_TEST_1 table's INVENTORY_CNT column i.e. existing value + count of new rows OR a full update by taking the complete row count (Grouped by item id) and update the INVENTORY_CNT column
