How To Rewrite MSSQL Update Statement To Work In Oracle
Dec 29, 2011
How do I write this MSSQL statement so it works in Oracle?
update b1
set b1.b1_app_status = r3.application_status
from conv_app_status_update a, statyp r3, b1perm b1
where a.spc = r3.serv_code
and a.task_des = r3.r3_act_type_des
and a.task_status =r3.r3_act_stat_des
and a.process_code = r3.r3_process_code
and r3.application_status is not null
and a.spc = b1.serv_code
and a.id1 = b1.id1
and a.id2 = b1.id2
and a.id3 = b1.id3

The following script doesnt work.
DELETE
FROM PSPROJECTITEM I
WHERE I.PROJECTNAME = 'TEMP1'
and (I.OBJECTTYPE between 79 and 84
or (I.OBJECTTYPE = 58
and I.OBJECTID1 = 104
[code]...
It gives the following error:

I have been asked to rewrite the following update statement without using the hint BYPASS_UJVC.
l_new_CFT_ID CASHFLOW_TYPE.CFT_ID%TYPE;
if (l_Record > 0) then
-- since at least 1 loan was found with the old type, process the actual update
update /*+BYPASS_UJVC*/ (
select
cfa.CFA_CFT_ID
[code]......
I think I am supposed to be using the Merge statement but I am not sure on how to go about it.

I must create an INSERT trigger, on an Oracle table, which will do an insert into my MS-SQL 2000 DB table.
The tables are exactly the same in this case and I desire to insert the entire row that was just insterted into the Oracle table into the MS-SQL table.
I understand how to create an ODBC connection between the DB servers, I just can't seem to understand the trigger syntax.

I am trying to compare records in a table in both Oracle and MSSQL database against a single standard dataset in my test case. However, I'm getting different results for each when I sort using a "order by".
select COL1 from TABLE1 order by COL1
In MSSQL, I get:
COL1
=====
A
A.
A++
A++.
In ORACLE, I get:
COL1
=====
A
A++
A++.
A.
I mean, oracle result some what makes sense, because "." has bigger ascii value than "+". But is there anyway to make the ORACLE sort order look exactly like MSSQL result?

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.

I was working on an applications program It is written in PL/SQL . It is running on an oracle 8i database It was not written by me but now I am responsible of it. I made some changes to database tables for this years regulations. Everything was working fine but yesterday I have recompiled two of the packages for some regulations and one of the procedures was stopped working.
It is called 'sayfa2'. Packages names are 'aday1' and 'aday2'. They both have a procedure called sayfa2 and both of them don't work now. They gave me no compilation errors. All I did is I have copied the original code from toad and compiled it at sqlplus I have changed nothing except some texts inside html tags. I couldn't guess what is wrong.
It actually converts to html pages. All procedures are working fine except sayfa2. aday1 is for to fill information and submit but when I click submit button it gives an error:
The requested URL /pls/kon/aday1.sayfa1 was not found on this server. Oracle HTTP Server Powered by Apache/1.3.19 Server at ...
There is also a problem with Turkish characters they don't appear correctly.
Below is sayfa2 and I also added aday1 package could you have a look at it .
PROCEDURE sayfa2(stuid VARCHAR2,tckimlik VARCHAR2, ad VARCHAR2, ad2 VARCHAR2, soyad VARCHAR2,
sex VARCHAR2, mdurum VARCHAR2, bad VARCHAR2, aad VARCHAR2,
dyer VARCHAR2, dgun VARCHAR2, day VARCHAR2, dyil VARCHAR2,
nil VARCHAR2, nilce VARCHAR2, nkoy VARCHAR2, cilt VARCHAR2,
asira VARCHAR2, sira VARCHAR2, asuba VARCHAR2, kang VARCHAR2, agorev VARCHAR2,

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.

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 have a table TEMP_TEST_1 to be loaded with multiple rows which contains the available items for a store with their sequence numbers. I also have another table TEMP_INV_1 which holds a column for inventory count of the items, and this column is to be updated after loading the first table TEMP_TEST_1.
The table TEMP_TEST_1 is updated through all possible channels in OLTP. So while updating the inventory, which is the best way. 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
--------------------------------------------------------------------------------
-- Initial setup SQL's, TEMP_TEST_1 is updates on OLTP through multiple channels
--------------------------------------------------------------------------------
CREATE TABLE TEMP_TEST_1 ( ITEMID NUMBER ( 4 ),
INVENTORY_CNT NUMBER ( 2 ) );
CREATE TABLE TEMP_INV_1 ( ITEMID NUMBER ( 4 ),
ITEMSEQ NUMBER ( 5 ) );
INSERT INTO
[code].......
--------------------------------------------------------------------------------
-- Inserts for new items in the store
--------------------------------------------------------------------------------
INSERT INTO
TEMP_INV_1
VALUES
( 1,
11 );
INSERT INTO
TEMP_INV_1
