SQL & PL/SQL :: Update Statement With Join Only Update Matching Rows
Aug 17, 2010This 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.

SQL CASE STATEMENT With Wildcard Character
Feb 2, 2010I am very new to Oracle APEX and having difficult with a SQL statement in a report page. I have the following sql code in the page region source.
Essentially, there are two drop down lists connected with the report. I want the first one (:P2_Retailer_ID) to be mandatory, i.e., the user has to select a value from the list, but the second one (:P2_JOBTYPES) to be optional.
So, if the user leaves :P2_JOBTYPES as "No Job Type Chosen" then the SQL returns all records where the retailer ID = P2_RETAILER_ID whereas, if the user also selects a value for P2_JOBTYPES then the SQL returns all records matching both on Retailer ID and Job Type.
However, for some reason, if the user leaves P2_JOBTYPES as "No Job Type Chosen" then no records are returned as it appears to be taking the '%' as a literal value rather than a wildcard.
SELECT * FROM RETPERFFW
Where "Retailer_No"= :P2_RETAILER_ID
AND (CASE
WHEN :P2_JOBTYPES <> 'No Job Type Chosen'
THEN :P2_JOBTYPES
ELSE '%'
END )LIKE "Job_Type_Schema"
PL/SQL - Generate Update DML With Special Character?
Dec 1, 2010I have a pl/sql question about interpreting special characters in pl/sql. I am generating an update statement and get an invalid character when the customer name has an ampersand in it (&). I�m now generating the update statement to include the customer name cut up with concatenation characters surrounding the ampersand, for example �CSCP-C�||�&�||�E�. However, pl/sql is still not executing the update.
Here is the code.
SET PAGES 2000;
SET LINES 200;
SET SERVEROUTPUT ON;
SET VERIFY OFF;
spool update_table.log ;
[code]....
The RESULTS follow. Of course, I can copy this statement and execute in sqlplus without a problem.

SQL & PL/SQL :: Get Old Value Of Column In Update Statement
Sep 17, 2007While 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.
PL/SQL :: Index Ignored While Using Update Statement?
Nov 26, 2012I 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.
PL/SQL :: Row Locking During Update Statement?
Aug 9, 2013Using 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.
Spatial :: Convert Multi-line To Simple Line
Feb 13, 2013Oracle Database 10g Enterprise Edition Release 10.2.0.4.0
We are processing spatial data from another source to display in our GIS environment. The data is a set of multi lines. The gtype is 2006. A typical geometry looks like:
SDO_GTYPE 2006
SDO_SRID 31370
SDO_POINT.X NULL
SDO_POINT.Y NULL
SDO_POINT.Z NULL
SDO_ELEM_INFO (1,2,1, 7,2,1)
SDO_ORDINATES (105094.84, 195084.96,
105094.54, 195080.22,
105094.84, 195084.96,
105094.84, 195084.96,
105094.68, 195082.47 )
Now, this is not an actual multiline... it's just encoded as a multi line, but if you look at the coordinates you'll see that the end point of the first line is the same as the beginning of the second line (105094.84, 195084.96).
A better way to encode this geometry would be:
SDO_GTYPE 2002 <---
SDO_SRID 31370
SDO_POINT.X NULL
SDO_POINT.Y NULL
SDO_POINT.Z NULL
SDO_ELEM_INFO (1,2,1)
SDO_ORDINATES (105094.84, 195084.96,
105094.54, 195080.22,
105094.84, 195084.96, <---
105094.68, 195082.47 )
Is there a standard function in Oracle that does this conversion for me? Or do I have to write my own :)
SQL & PL/SQL :: Update Statement By Joining 2 Tables
Mar 24, 2012I 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.

But I'll keep getting flagged at the tbl2.EMPIDA column reference. I have not tried this in SQL Plus, just in TOAD, but it seems to repeatedly fail.I have had to dump records to standalone Access tables and link back to perform the updates.
