Is is required to check the number of rows updated in a table when the primary key of the table is used in the filter criteria of the update statement? As I know,by default it will update only one record. But if it happens to be an important transaction table and only one record is required to be updated, then is it the best practice to use the 'SQL%ROWCOUNT' check in the query, even if the update query is using primary key in filter clause.
Example:Consider Trans table with trans_id as primary key. Then: Update Trans set trans_status='pass' where trans_id=123;
I know this will update only one record. But what is the best practice? Shall I use 'SQL%ROWCOUNT' after this update to double check whether the record is updated or not?
update siebel.s_contact set marital_stat_cd = case when (marital_stat_cd = 'Casado') then 'Married' when (marital_stat_cd = 'Solteiro') then 'Single' when (marital_stat_cd = 'Divorciado') then 'Divorced' end
As you can see i forgot the else, so my update is wrong.
I thought i could rollback the update issuing the rollback statement, but when i have issue the rollback, the i query the table to confirm that the update was rollbacked and for my suprise the update is commited.
I didn�t issue the commit statement after the update and i confirmed that the auto-commit feature to worksheets is disabled, so i don�t understand whit the update was commited.
Inside procedure,I need to validate all the columns (Ex:col1 should not accept more than 40 chars) and update status(containing error or not) of these columns into another column in the same table.For this,I mentioned only 'UPDATE' statements.So 'WHERE' clause of some update statements not using Primary keys.
In that table composite primary key was created.This procedure is successfully complied & executed now.But this procedure took more than 10 mins to execute.I need to reduce the time to less than a min.
I am using the Oracle 10g and I have question related to "for Update" clause.We have the data warehouse db, so no foreign key constraint between parent and child.We process the data files every hour, the condition is If we find the row in parent table then we go and look into child tables and perform insertion (if no corresponding record is present) or updation (if one corresponding record is present) in the child table.
The problem is If I run the two process simultaneously for the same kind of data, and if no record is present in the child table then it create the duplicate in child table.My question is if I use FOR Update clause while selecting the data in parent table will it lock the child table for any insertion or updation?
Ex- We have employee table for employee 1
In my data files I have the row for employee 1, so when I run the select query on employee table I found 1 row.The I look the child table "Salary" as there is no record for emp_id =1 in this table I insert the record for this
Emp_id Salary 1 500
The problem is if both the process run at same time then I get duplicate rows in child table
Emp_id Salary 1 500 1 500
we do not want the duplicate row insertion. Can I lock the child table during first process run
I have a function that returns the total sum of an account. From reports I call the function passing the account code. The function sums the values for that specific account code and returns the value. In my function I have the following code :
where account_code = P_CODE.
Eg. The value of :P_CODE is 'CS'.
I now want to pass multiple account codes ('CS','TV',LJ') to the function. How do I change the IN clause in the function to accommodate multiple values.
I have tried using the instr function, but it does not work. eg. AND instr(o.ACCOUNT_CODES,','||P_CODE||',') > 0
I have created a Data block - 'CONTACTS' (Database data block) and has database item - 'Code', 'Descr'
The number of records displayed is set to 5.
Value When checked - 'Y' Value When Unchecked - 'N' Check box mapping of other values - 'unchecked'
The requirement is when i check one or multiple checkboxes, i should pass the 'Code' item values to the WHERE clause.
Right now whenver i am trying to do so, only the current record value is copied to the WHERE clause.
I have tried using basic loop as well as while loop but things havmt worked. Below is a basic code which will work for one record, request to guide me with muliple checkbox ticked.
IF :contacts.cb = 'Y' THEN
IF p_where is null then
p_where := :contacts.code; else p_where := p_where ||','||:contacts.code; end if; end if; p_where:= 'where code in ('||p_where||')';
Are some posibilities to exclude duplicate values do not using sql aggregate functions in main select statement? Priview SQL statement
SELECT * FROM ( select id,hin_id,name,code,valid_date_from,valid_date_to from diaries )
[Code]....
In this case i got duplicate of entry TT2 id 50513 In main select statement cant use agregate functions are even posible to exclude this value from result modifying only the QLRST WHERE clause (TRUNC need to be here)
I have a problem with Between clause used in where statement to compare two string variable.
Query is like this,
select item_code, item_deacrption from itm_master, invoce_det where im_code = item_code AND invd_item_number BETWEEN (:startNum) AND (:endNum)
Here invd_item_number is a DB field and is of type varchar2(41), and (:startNum),(:endNum) are of same type.
now invd_item_number has one value '001003002001' if we give :startNum = '001003001002' and :endNum = '001003004006'
:startNum and :endNum is composed of separate field values (ie, 1st 3 character shows color code, next 3 for catagory, next 3 for size etc). These codes are entered separately and are combined at run time.
it is still fetching the invd_item_number with value '001003002001'. (the last set of character(type code) in the :startNum is greater than invd_item_number's type code value. But it is smaller than the previous code (size code), that's why it is fetching).
But how can i get around this as i don't need that value to be fetched.
I have the following query : for :P_LEG_NUM Parameter when i am passing values like 1,2,5 as string type i am getting invalid number error... I have defined in clause for it but still it does not work.. For individual values like 2, etc it works... how can i pass comma separated values for this bind variable

I have a table called 'price' and want to update it with a table called 'update'. See workbook in the attachment.
The idea is to update the table 'price' with values from 'update' as long as the values from 'update' are different then the values in 'price' or the value in price with 'enddat' empty is not present in 'update'. you can still follow this...
Example:
Enddat for df_location 4 from 'price' is empty and df_location 4 is not present in 'update' so 'enddat' for this df_location should be filled with any date from 'update' (there is always going to be just one distinct date).
I have tried something like this:
proc sql; insert into work.price (enddat) where enddat = '' select (date) where df_location not in (select df_location from work.update); ; quit;
Well this obviously doesn't work. I'm trying to pass 2 criteria (when enddat is empty and df_location is not present in 'update') but I'm not sure where to put them...
I want to know about if I want to store previous values of a table row before updating through Forms, like in Database Trigger where we are referencing old values as :old.etc to get Values Before Update, how I can achieve this in Oracle Forms 6i or above versions.
for example: I made a form Employee to manipulate data by a user, if user update a record I want to store previous values before Commit in trigger Pre-Update with some additional information. I do not want to use a Trigger on that Table.
how can i make this script into a function or procedure which instead of user change the crime_id :=4 or 5 directly it actually can grab the id from a update statment like
UPDATE CRIME_STATUS SET CRIME_STATUS = 'open' WHERE CRIME_ID = 9; pick 9 and insert into the above statment so it runs as normal

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.
I have a large table and want to calculate just a few values. Therefore, I don't want to create a new table, I want to update the table. Here an example:
I want to calculate the VALUE_LAG with ID = 4 only (-> two values).
create table zTEST ( PRODUCT number, ID number, VALUE number, VALUE_L1 number );
[Code]..
I tried this, but obviously, windows functions are not allowed in the update statement.
update zTEST set VALUE_L1 = lag(VALUE) over (partition by PRODUCT, order by ID) where ID = 4
When I execute the query, it returns the data (approx - 40,000 rows) in 1 min.But when I try to insert this data into another table (or create a table of this data) it takes me about 2 hours.
Tried using Materialized view, its again the same the refresh takes 2 hours.Basically here, what I am trying to do is the data from the above query is used to update the values in another table.What ever the procedure I am trying it takes 2 hours.
I have two tables lets say TAB_A and TAB_B. I altered table B to include a new column from table A I wrote a merge statement as follows to merge the data
MERGE INTO TAB_AUSING TAB_BON (TAB_A.SECURITYPERSONKEY=TAB_B.SECURITYPERSONKEY)WHEN MATCHED THEN UPDATE SET TAB_A.PPYACCOUNT=TAB_B.PPYACCOUNT;
I know INSERT is for inserting new records UPDATE to my knowledge is to modify currently existing records (loosely) MERGE is one I rarely used, until this particular scenario. The code works perfectly fine, but I was wondering how could I write an update statement? Or in this scenario should I even be using an update statement?
Table LEAVE Column Type Null Description APP_NO Number(6,0) Not Null PK Leave Application Number ECN Number(6,0) Not Null FK Employee Code Number APP_Date Date Not Null Date of Application From_Date Date Not Null Date from which the leave starts TO_Date Date Not Null Date upto which the current application leave remains i.e. end of leave applied for date NO_OF_Days Number(2,0) Not Null Difference between TO_Date and From_date LEAVE_TYPE VARCHAR2(3) Not Null Can be one of SL, CL, LWP or LTA Status VARCHAR2(25) Not Null Can be one of Saved, Rejected or Approved Remark VARCHAR2(100) Nullable Reason to be put if status is rejected [code]....
What I really want to do is that when a record is inserted in the LEAVES table (an application for leave is submitted by any employee and if it is approved) then I want to update the _USED values of the corresponding LEAVE_TYPE in the LEAVEENTITLE table which holds values of types of leaves entitled to employee.
For example if 3 rows are inserted in the LEAVES table as INSERT INTO LEAVES (APP_NO,ECN,FROM_DATE,TO_DATE,APP_DATE,NO_OF_DAYS,LEAVE_TYPE,STATUS,REMARK) (1,1234,'2012-01-01','2012-01-05','2012- 01-01',5,'SL','APPROVED',null); INSERT INTO LEAVES (APP_NO,ECN,FROM_DATE,TO_DATE,APP_DATE,NO_OF_DAYS,LEAVE_TYPE,STATUS,REMARK) (2,1235,'2012-01-01','2012-01-05','2012- 01-01',5,'CL','SAVED',null); INSERT INTO LEAVES (APP_NO,ECN,FROM_DATE,TO_DATE,APP_DATE,NO_OF_DAYS,LEAVE_TYPE,STATUS,REMARK) (3,1236,'2012-01-01','2012-01-05','2012- 01-01',5,'LTA','REJECTED','Clash with the annual meet, revise dates');
Then the value of SL_USED in the LEAVEENTITLE table of record corresponding to the ECN = 1234 should be updated with +5 and naturally the SL_ UNUSED value of the record should be updated as SL_ENTITLED - SL_USED. For the APP_NO 2 and 3 none of the values in LEAVEENTITLE should be updated as the STATUS is not 'APPROVED'
I tried with the following trigger, but is compiling with a warning (not showing what the warning is)
CREATE OR REPLACE TRIGGER leaveentitle AFTER INSERT ON LEAVES FOR EACH ROW BEGIN UPDATE LEAVEENTITLE LVE SET LVE.SL_USED = SL_USED+(CASE WHEN :NEW.LEAVE_TYPE = 'SL'&& NEW.STATUS='APPROVED' THEN :NEW.NO_OF_DAYS SL_UNUSED=SL_ENTITLED - SL_USED ELSE 0 END), [code]....
I have created a form. Some of the elements are hidden such as updated_by and update_date. I have provided the default values for these attributes as pl/sql expression in the "default section" (Application->page->edit page item). I am using the Process Row process that is automatically created when a form is created.
The problem is when I click the update button, the updated_by and update_date is passed as null values which throws an error from the database.
I'm trying to update a number field on an apex page by summing up the values of multiple page items. I've tried to follow this tutorial
[URL]........
especially the "Create a Set Value Dynamic Action Using PL/SQL" part.
In the tutorial example they return an page item value P3_SAL multiplied by a multiplier they've determined by another page item's case. What I want to do is much simpler in that I just want to add up multiple page item values and then display them in a number field at the bottom of the page.
so the code I tried to use based on the tutorial is in the tab: Home >Application Builder>Application 103>Page 3>Edit Dynamic Action>Create / Edit Action
Set Type: PL/SQL Function Body
PL/SQL Function Body:
BEGIN return :P3_ITEM1+P3_ITEM2+P3_ITEM3; END;
Page Items to Submit: P3_ITEM1,P3_ITEM2,P3_ITEM3
But it gives me an error that I need to declare the identifiers, yet it works if I only use one item and I can perform any arithmetic.
I want to UPDATE the field DCR of the table TEST1 with the VALUE of the field DCR2 of the table TEST2.At the end, after the update, the table TEST1 would be like that:
