SQL & PL/SQL :: Write A Script That Automatically Increments And Inserts Values For Already Existing Rows
Aug 21, 2012
I have a table named student_details with columns "NAME","ADDRESS","COURSE" with several rows of data already insertedI have to add one more column "ID" which increments automatically.
I tried to do this using SEQUENCE but no values got inserted for already existing rows in "ID". how to write a script that automatically increments and inserts values for already existing rows also.
I have a data in one table with 6 columns where user may be updating values in all of these 6 columns or he may enter 3 or 4 columns based on that inserts should take place, this is similar to my previous thread , i am using if condition to check column for null if its not null then i will make a insert , but is there any other easier way to do this.
insert into ot_po values ('ss-po',1,ph_sys.nextval); insert into ot_inspect_head values (inh_sys.nextval,'ss-ins',1,'ss-po',1); commit; select * from ot_inspect_item
--Now if the inspection user issues the update statement , it will delete this row --from ot_inspect_item and reinserts the values with values based on --ii_flex_01,ii_flex_02,ii_flex_03 [code]...
(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'
(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.
I have a table called "Subjects" which lists subjects to match with notations in another table I have created a simple sequence (CREATE sequence subjectid) to created the subject id for the table. But I notice that if there is a skip in the date, the sequence increments automatically when I am not even using it. It even appears to be incrementing even when I am not doing any database activity.
This is not an issue of data integrity, because the values in the subject_id column do not need to be sequential, they just need to be unique. But it really has me curious. I created another table called "keep_track" to keep track of what is happening:
I used Region, Process by to search the report which appears as shown above. Then I use Choose Auditors column to select my Auditor and copy paste it into the report under To be Audited By col. Is there a way to automate the process. I am here using a tabular form in APEX. My main aim is to assign auditors based on Region, not equal to Processed by.
I'd like to get all rows for one particular id. I have data stored in two different tables. I'd like the values to be "denormalized" such that for each unique date I want the values(washer_val, widget_val) for each id from each table to be displayed(or null if no data for that date).
I've created two different example views("tables") of my data with a "with" statement(washers, widgets). I tried to denormalize each set of data (washers_val, widgets_val) and then get all the unique dates (unique_dates). I then join the "views" and display all possible rows with their data. This is the type of output I want BUT is there an easier way to achieve it??
with washers as (select 1 id, trunc(sysdate) event_date, 1 val from dual
I want to get the values and put them into html template since i want to configure mime settings. My table's name is rawticket_voip and it has 150.000rows and 20 columns so instead of COL1, COL2 what should i write there? How can i get the spesific row's and column's value and how can integrate loops in this html?
TABLE_A ------------------------------ ID DEPT CRS ------------------------------ 1 CS CS_100 2 SCIENCE SCI_150 3 MATH MATH_400 4 HISTORY HIS_110
[Code]...
To display CRS from TABLE_A where DEPT = 'MATH' but in the following format.,
-------------------------------------------- NO DEPT CRS -------------------------------------------- 1 MATH MATH_400, MATH_550, MATH_230 --------------------------------------------
instead of., -------------------------- NO DEPT CRS --------------------------- 1 MATH MATH_400 2 MATH MATH_550 3 MATH MATH_230 ---------------------------
I have two tables which have identical schemas, one table (tbl_store) is used to hold the latest version, and the other table (tbl_store_audit) holds previous versions. When the latest record is updated, it is inserted into the tbl_store_audit table as a revision, and the updated details are used as the latest record.
For example: The latest version is held in tbl_store, however the tbl_store_audit may hold 5 records which are the past records used before changes were made - these are seen as revisions.
I want to be able to compare what has changed between each revision in the tbl_store_audit table. For example: Out of the 10 columns, the change between revision 1 and revision 2 was the size from XL to XXL. The change between revision 3 and revision 4 was the size XS to M and price 4.99 to 10.99, and so on.
Eventually i will create an APEX report that will show the user the revision number and what was changed from and to.
I seen in a previous post i need to note my oracle version: Oracle version 10.2.0.4.0
How do I limit my query to show the information from REQUEST but only where the all of the wips associated between REQUEST and WIPS are not in the SHIPPING table. For example, the SHIPPING table has all of the WIPS that have been shipped, I only want to show the REQUEST rows where all of the WIPS have not shipped.
I am an Oracle beginner and I am having some trouble with the following insert query.
I am inputting values into text boxes and then this is carried out as a trigger upon clicking a button.
INSERT INTO client VALUES(':student.txtclientid', ':student.txtclientname', ':student.clientaddress', 13564338); INSERT INTO enrolment VALUES(':student.txtclientid', ':student.lstoccurrence', null, null);
The above text boxes are all working fine as I have viewed the values using the message command. My proplem is that if i leave the fields blank it inserts ':student.txtclientname' into the row, otherwise it returns "Could not insert record"
I am trying to come up with a sql select statement that provides all rows for employees with 2 or more cities.
with sample_table as ( select 'John' name,'city' ValueType,'Toronto' Value from dual union all select 'John' name,'city' ValueType,'Vancouver' Value from dual union all select 'Susan' name,'city' ValueType,'Toronto' Value from dual union all select 'Susan' name,'city' ValueType,'Seattle' Value from dual union all select 'Susan' name,'age' ValueType,30 Value from dual union all select 'Susan' name,'city' ValueType,'Atlanta' Value from dual union all
[Code]...
NAME VALUETYPE VALUE ----------- ------------- ------------ John City Toronto John City Vancouver Susan City Toronto Susan City Seattle Susan Age 30 Susan City Atlanta David City Chicago David age 35 David Status married David City Dallas
The above code is just to describe the sample table and the desired result set. Please note that Mary is not on the result set since she has no city assigned to her. Also Julia is not on the result set since she only has one city assigned to her. The others are there because they had at least 2 cities assigned to them.
I need the sql syntax that would return this result set.
I have a large table with a few billion rows. I need to find ITEM_NAME values in ITEM_MASTER table containing " " (spaces) and replace them with other values. This has to be done within the same script. The replacement values could be any characters or numbers, but not spaces.
The whole reason for this table is testing big databases, so it does not matter what it contains. The reason I need to replace them is that this table will be dumped to a space delimited flat file and spaces within values are not acceptable.
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 two tables eim_asset and eim_asset1.I want to update the table eim_asset1 using the following update SQL (Or Logic)
update eim_asset1 set emp_emp_login = (select login from s_user where row_id in (select row_id from s_emp_per where row_id in (select pr_emp_id from s_postn where row_id in (select position_id from s_accnt_postn where ou_ext_id in (select row_id from s_org_ext where row_id in (select owner_accnt_id from s_asset where owner_accnt_id is not null)))))
It gives me the ORA error : ORA-01427:single-row subquery returns more than one row.know why I am getting it, because of the one-to-many relationship between owner accounts and their assets.

Is there a way to check in that date grouping for matching ticket_origin and ticket_destination when there may be two or more rows difference between them that does not allow me to use Lead or Lag function. Is it also possible do so without using the amount column? I also would like to identify if they are in the same area when paired (this I believe works after getting table sorted like so below then use lead lag after having the order by done) I am trying to get something like this table with results as
select to_date('8-18-2013','mm-dd-yyyy') dt, '123_' ticket_origin, '123' ticket_destination,101 startid, 101 origin, 0 destination, 'origin' objecttype, 85 amount, 100 area from dual union all select to_date('8-18-2013','mm-dd-yyyy'), '123', '123_',0, 0, 103, 'destination', 85, 100 from dual union all select to_date('8-17-2013','mm-dd-yyyy'), '124._', '124.', 105, 105, 0, 'origin', 150, 200 from dual union all select to_date('8-17-2013','mm-dd-yyyy'), '124.', '124._', 105, 0, 106, 'destination', 150, 300 from dual union all select to_date('8-17-2013','mm-dd-yyyy'), '127_', '127', 108, 108, 0, 'origin', 50, 600 from dual union all [code]...........
i have multiple inserts to make in a table that is in an Oracle database...i already try several ways to do it but it always giving erros... how to make multiple inserts at same time.
We have two databases one localdb with user rakdb and another one remotely remotedb with user rakdb .We need to be in sync with data in one table called om_item, where the users are inserting data on daily basis and the user sends us the insert script everday to run it on local databse to insert the new records in local database.I managed to create a file which records all the inserts into one text file in one directory.Can we have a scheduler to pick this text file from the specified folder and send mail using utl_mail.

I'm on 11.2 DB and need to create an audit table that will be populated by DB triggers of other tables (after Insert,Update and Delete). The triggers will only ever be inserting data into the audit table. I have read that for insert only tables, you should define the 'pctfree' as 0. Is this correct? Do I need to set any other params (like pct_used) for tables only ever being inserted into?
I want to load 10 millions records from staging table to master table.One logic must be take during the load, the logic is rows already present in master table means, we need to update corresponding rows in master table otherwise rows insert in target table.
I have been using bulk collect and forall method to load data. it shows better performance compare then cursor row by row process. As per oracle doucmentation, we cannot use SELECT statements inside FORALL condition so we could not use logic inside the forall condition.
