SQL & PL/SQL :: Can A Procedure Be Used In Update Statement
Aug 2, 2011
PROCEDURE split_name (
full_name IN VARCHAR2,
name1 OUT VARCHAR2,
name2 OUT VARCHAR2,
name3 OUT VARCHAR2,
name4 OUT VARCHAR2,
name5 OUT VARCHAR2
)
the above is the procedure declaration. i want to use this function in updating the records in a table. this procedure is working fine in forms and it is splitting the names perfectly and i dont know how to use this in update statement as it is not returning anything like functions do.

I have to update 20 and 60 million records of a table. The update statement are
1> 20 million recs
update mycustomer set update_time=add_months(sysdate,240) where seq_num = 1;
commit;
2> 60 million recs
update mycustomer set update_time=sysdate-seq_num where seq_num <> 1;
commit;
Q1> Is there any way to improve performance
Q2> Will parallel dml improve performance
Q2> Would a pl/sql cursor make any difference in speed.

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.

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

After an Update statement, Sql%NotFound is being validated. Sql%NotFound validates to true even though a record matching the update condition is found. Because of this, the procedure execution Exits. If the Sql%NotFound is commented, then the Record gets updated. which is validating Sql%NotFound condition to True.

I have two tables have almost the same columns, how can I use merge statement to update the target table only when there is difference between source and target table. Is there any easier way not compare each column one by one? I am using Oracle 11.2
Here is the MERGE statement:
Merge into tb_trgt trgt using tb_src src
on (src.id = trgt.id)
when not matched then insert (trgt.id, trgt.nm, trgt.addr) values (src.id, src.nm, src.nm)
when matched then update set trgt.nm = src.nm, trgt.addr = src.addr
where trgt.nm <> src.nm or trgt.addr <> src.addr
;
Is there any easier way to specify the where clause in the NOT MATCHED? I don't want compare each column of the tables. Since I may have many columns in the tables.

I've seen this example numerous places, and tried to implement it, but I keep getting an "invalid identifier" error message, despite the fact that I've got the table and column specifically identified.For instance, my query reads like:
UPDATE tbl1
SET tbl1.EMPID =
(SELECT tbl2.EMPIDA FROM tbl2
WHERE LOWER(tbl1.EMAILCOL) = LOWER(tbl2.EMAILCOL2)
)
WHERE tbl2.EMPIDA IN ('Z1O435','S8M4722','M0D5156')
AND EXISTS
(SELECT tbl2.EMPIDA
FROM tbl2
WHERE tbl1.EMAILCOL= tbl2.EMAILCOL2 );
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.

I'm working on a project and I can't figure out the procedure I will need to use. I've got a sysdate field in my "Calls" table which generates a call date + time, however I need to insert a severity level of the call after a certain amount of time,
e.g. after 1 hour level turns from level 4 to level 3 and so forth until reaching level 1 after x amount of time. I know I'd need to put in an else if statement within this procedure I just can't work out how to do it with the sysdate field that has also been created.
A bit of info about the table, table name = calls, column 1 = date_time and column 2 is called severity_level

Updating multiple ROWS with different values using single statement. Requirement is to update one column in a table with the values in the other table.
Say we have 3 tables, CORPORATION,CORPORATE PROFILE and MEMBER.
Each MEMBER has CORPORATE PROFILE which in turn is associated with CORPORATION. Now I need to update MEMBER table with CORPORATION identifier for members who belong to corporations with identifiers say 'ABC' and 'DEF'.
MEMBER table contains column 'CORPIDENTIFIER '. CORPORATEPROFILE table contains MEMBERID and CORPORATIONID,this will associate a member with the corporation. CORPORATION table contains ID and CORPIDENTIFIER.
Using the below query I am getting error,ORA-01427:single-row subquery returns more than one row
UPDATE MEMBER M SET M.CORPIDENTIFIER=
(SELECT A.IDENTIFIER FROM CORPORATION A,CORPORATEPROFILE B
WHERE B.CORPORATIONID=A.ID AND B.MEMBERID=M.ID AND (A.IDENTIFIER LIKE 'ABC' OR A.IDENTIFIER LIKE 'DEF'))
Sub query in the above query returns multiple rows and hence it is throwing the error.More than one members are associated with Corporations ABC and DEF. Is there any way possible to update all the rows in single query with out iterating the result set of sub query.
