Insert / update in same table

SQL> select * from test;
TT NAME
1 hi
1 re
1 go
2 rw
2 gh
2 lk
6 rows selected.
This is just a dummy table,but I would like to know how can I update the values of TT=2 to make it identical with the values of TT=1
The table should look like
SQL> select * from test;
TT NAME
1 hi
1 re
1 go
2 hi
2 re
2 go
In reality the records go into lacs

One way:
(untested)
Delete from Test where TT=2;
Insert into test t1
select 2, t2.name from test t2 where tt=1;Added where clause, just in case if there are more values for TT.

  • XML PARASE and insert /update in corresponding tables

    Hi,
    I have a XML in which master details tables 3 tables.I want to separate element and insert/update in corresponding tables dynamically.
    Table invlovled in A,B,C
    Thanks

    The easiest way to do this is along the following lines..
    (1) register an XML Schema that describes the XML you wish to process with theh database.
    (2). create a relational view for the top level elements and for each repeating element (element where maxOccurs > 1 in the XML Schema)
    (3) Use 'insert as select' or other SQL type processing to update your relational tables from the contents of the view
    It is normally recommended that you add the following annotations to the XML Schema before registering it with the database
    (1) At the schema level set xdb:storeVarrayAsTable="true".
    (2) At the complexType level set xdb:maintainDOM="fasle".
    If you search the forum you will find a lot of examples of creating relational views of XML content stored in the XML database. Typically these examples will include key words like 'create or replace view' and 'table(xmlsequence(extract' or 'xmltable'.
    Hope this helps...

  • Inserts/Updates on replicated tables Logical Standby Database ??

    Hello all,
    We have a Logical standby database on 10.2.0.5. Can you please suggest if there is a way we can do data inserts/updates on replicated tables ?
    Can this be done by doing a alter database guard none; or alter session disable|enable guard; ?? Even if it completes succesfully , will this have any effect on replication later ?

  • Insert data in same table based on some condition

    Hi. I am new to this forum.
    I have to write a stored procedure to Insert Data into a table say MYTABLE ,having structure as:
    Col1 Col2 Col3 ................ TotalInstallments CurrentInstallment PaidAmount MonthYear
    I have to insert all the data as it is in the same table(MYTABLE) except changing some fields on basis of some conditions:
    1. if PaidAmount>0 && CurrentInstallment<TotalInstallment then
    CurrentInstallment=CurrentInstallment+1
    2. In the MonthYear field I am having data in formate(month/year)ex. 01/2012, 11/2012 ....
    So I have to insert data by incrementing month and year. for example:
    if currentdata is 11/2012 then next data will be 12/2012
    But next will be 01/2013
    I have to select all the records which belongs to previous month(through MonthYear field ) and put checking & changes on each record of the selected data and then insert them into same table(MYTABLE).
    How to achive that?
    Thanks.

    Every thing is working fine but some strange result as:
    when i run my Procedure TRANSFERDATATONEXTMONTH
    1. by Passing Value as : CUSTOMERID_var ='ABX101' and MONTHYEAR_var='12/2012' it insurts 5 rows
    which is correct , since I have 5 records where CUSTOMERID='ABX101' and MONTHYEAR='12/2012' and
    new 5 rows has CUSTOMERID='ABX101' and MONTHYEAR='01/2013' (all other values are as expected)
    2. now when i again run by passing values: CUSTOMERID='ABX101' and MONTHYEAR='01/2013' it inserts 10 records(just double )
    and new records has value CUSTOMERID='ABX101' and MONTHYEAR='02/2013' (while on the basis of condition CUSTOMERID='ABX101' and MONTHYEAR='01/2013' i have in my table only 5 records)
    and all records are duplicate. Some times it inserts three times , while on condition basis it should no. What is happening?Probably, meanwhile you were trying to Insert the First time and the second time, someone did run the procedure that Inserted 5 More records for 01/2013. And, hence your Second run inserted 10 records instead of 5.
    >
    Why it is inserting double of records while i have only 5 records on given condition? Am I missing some thing?Yes, you are. You are missing your Tables, Your Dummy/Sample Data, Working Procedure/Function that can be replicated.
    Without this, we cannot simply believe on assertions that Oracle is behaving incorrectly.
    In addition to this, the GetMonthYear function, should be scrapped. It is un-necessary, when the same logic can be achieved using Oracle ADD_MONTHS function (See my previous post). And you are storing the MonthYear in a Varchar field, which ideally should be a Date field. This eradicates the un-wanted need to cast from VARCHAR - DATE - VARCHAR.

  • Using Case statement to insert,update,delete  the tables

    Hi All,
    I have to check the databse ,
    if it is developement then

    insert/update/delete values in tables;
    if it is production then

    For doing the about i am trying to write CASE statement like this
    SELECT function,

    when fun = 'developement' then insert into table1 values ('abcd','1234')
    when fun = 'staging' then insert into table1 values ('abcd','1234')
    when fun= 'production' then insert into table1 values ('abcd','1234')
    else null
    from dual
    its throughing me an error
    please help
    Thanks,

    Hi,
    You can use CASE staement any place where an expression is expected.
    For example, in:
    UPDATE  table_a
    SET     col1 = exp1
    ,       col2 = exp2
    WHERE   exp3 = exp4;all the expressions are labled lke expn.
    Note that table_a, col1 and col2 are not expressions: you must hard-code these names, or use dynamic SQL.
    So it's okay to say:
    UPDATE  table_a
    SET     col1 = CASE
                       WHEN  db = 'development'  THEN  0
                       WHEN  db = 'staging'      THEN  1
                   END
    ,       col2 = CASE
                       WHEN  db = 'development'  THEN  NULL
                       WHEN  db = 'staging'      THEN  col2
                   END
    WHERE   db != 'production';In this example:
    in the development database, col1 is set to 0 and col2 is set to NULL
    in the staging database, col1 is set to 1 and col2 is unchanged (that is, set to what it already was)
    in the production database, nothing is changed (the WHERE condition is always FALSE)

  • Problem in Master-Details  - Inserting Records to same Table

    I have 3 column of one table in master as primary key and 3 column of same table in detail as primay key. These 6 column collection as the composite primary key. when i try to insert the records in detail table it showing me Too many objects match the primary key oracle.jbo.Key Error.
    I have done the Following things:
    In HR Schema, I have created one Transient View Object for Master and Employee View Object for Details.
    I have taken EmployeeId, FirstName and LastName columns in the Master i.e., From Transient View Object and droped it as the Form.
    And I have taken E-mail, JobId, ManagerId columns in Details i.e From and droped it as the Table.
    When I entered values in master and click CreateInsert in the details record. It showing me Too many objects match the primary key errors.
    Help me out!!! for this problem.

    Hi Kumar,
    I was not in office for couple of days. Thats you couldnt reply for your earlier post. You had mentioned how can we set the value of the import parameter.
    What i wanted to tell you is not to set the value for that Binary_flag, but that flag influences the data download in ASCII FORMAT.
    You just try this: Try attaching a file through CL_CRM_DOCUMENTS~CREATE_WITH_TABLE. Before read the contents of a file into SAP using GUI_DOWNLOAD and read it in ASCII mode. Now when you try to pass this to Ascii internal table of the method specifing the MIME type, it will attach the document to the opportunity, but the document content will be still in ASCII.
    If you try to download this file using GET_WITH_TABLE, then you can see BINARY_FILE is not set to 'X' and the content gets downloaded to Ascii internal table.
    This is my observation.
    I think when attaching documents in Opportunities by default, it reads the file in Binary mode. Because when i tried to attach a file directly in Opportunity transaction, and tried the method GET_WITH_TABLE, the BINARY_FLAG was set.
    Hope now you understood, why i was mentioning that BINARY_FLAG influences the download of content in binary and Ascii format.

  • Interfaces used for insert/update data in tables

    for providing security the procedures are not allowed to directly insert/update the values in tables.some one suggested that use interfaces for this .i want infomation about this interfaces. how this works and how to use

    An interface is an intermediate set of procedures/functions that do the job for you.
    You haven't explained what it is you're trying to achieve exactly, but here's an example scenario.
    We don't want to allow our developers to query, or write to the tables directly so they are set up with certain database users that have no permissions granted on the tables for such things.
    Instead they have been granted permission to call procedures and functions belonging to another schema, and it is those procedures and functions that do the required table access and/or pass information/data back or write to the tables.
    The developers have to write their applications to call these procedures to do any access to the tables. This means that they are limited to the functionality provided by these interface procedures so, if there is internal auditing or columns of data etc. on the tables then it may be that they can't access this data, but only the "user facing" data.
    The interface can also ensure that data meets certain requirements before being written to tables, allowing for business or technical level restrictions to be implemented.

  • Concurrency when inserting in the same table

    Hi,
    I have a report used by several users and in this record there is a sentence to insert in a z table. My question is, what happens whether two or more users are inserting records in that table at the same time?  There is a concurrency problem, isn't there?
    How does SAP manage this issue? or, what must I do in this case?
    Thanks in advance.

    As SAP applications are accessed by many end users at same time, SAP has concept called LOCKING of particular tables involved in the transaction.
    You can achieve your requirement as below
    Go to t-code SE11, and create a lock object for your Ztable
    Now, system create 2 function modules - 1 for locking ENQUEUE_* & other for un-locking DEQUEUE_*  ( search for function module in SE37 )
    Before saving data to ZTABLE, call function module ENQUEUE_* to lock the table for writing data, if locking fails, means there is somebody already working on it, hence you can display error message
    After Save action, you can unlock the table by using FM ... DEQUEUE_*
    Note: you can lock and unlock event during DISPLAY/CHANGE mode if your requirement requires.
    Hope this helps you.
    Regards,
    Rama

  • Ruleframe + Updates in same table on different records

    I have following problem :
    Change event with DML for one column in one record have to result in an update of different records in same table
    if business rule is validated, I get a problem in the cg$AUS trigger, No data found.
    In the business rule (on after row triggering level), I call a procedure, which do the updates on the same table.
    What do I do wrong. Do I have to start a new transaction for this ?
    I hope someone can help me.
    Regards
    Jo-an

    Jo-an,
    You definitely don't have to start a new transaction, you should just use the tapi upd procedure to perform the update, as described in the Headstart User's Guide.
    Could you try again and report back if you still have the problem?
    kind regards,
    Sandra

  • Fetch Insert / Update Query From Table Trigger

    Hi everyone !,
    I have a situation, is there any way where I can get insert/update query by before-insert / after insert trigger when a user inserts/updates any row in the table.
    Plz....help me....champs.....

    That was a nice thing but it works only on some oracle 9i with DML statements.
    On database versions 9.2.0.1 to 9.2.0.6 ora_sql_text works and returns the calling text for dml triggers, where as starting from 9.2.0.7 the behavior has changed and returns NULL.
    Cause
    This issue had surfaced from 9.2.0.7.0 patchset. After discussions in Bug 4171597 which was closed as a duplicate of Bug 4230721 it was concluded that it was the expected behavior i.e ORA_SQL_TXT should return null when dml triggers are used.
    ORA_SQL_TXT is a "System defined event attribute" and is supposed to work only with "System triggers". This is also what the Documentation says - "Application Developers Guide : Fundamentals(9.2)
    Chapter 16 Working with System events".
