Is it possibel add partitions an existing table that does not have any partions? If so what would the syntax look like. I have been racking my brain trying to do it. Probably long enough were I should have just created a new table with partitions and loaded the data too it. Now I am just curious
There is no ALTER TABLE....PARTITION BY HASH/RANGE/ETC syntax, you will have to create the table from scratch

Hi All,
I need to get the "Creation Script" of the existing table using c# and without using SMO dlls (is it possible? I don't know).
I.e. In SQL Management Studio -> right click on any table -> Script table as -> Create To - > open in the new query editor window. This will give you the schema of the table with the constraints of the table.
For E.g. In Northwind database, for the table "Categories", I would like to get it as show below
USE [Northwind]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Categories](
[CategoryID] [int] IDENTITY(1,1) NOT NULL,
[CategoryName] [nvarchar](15) NOT NULL,
[Description] [ntext] NULL,
[Picture] [image] NULL,
CONSTRAINT [PK_Categories] PRIMARY KEY CLUSTERED
[CategoryID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
I would like to get the same schema using c#. Please help.
Thanks & Regards,
Kalai.SMO is the easiest way to get this. This is what Management Studio uses. If you can't use SMO, get a Profiler trace of the queries that SMO executes when generating the script and execute the same using ADO.NET.

How can I convert an existing table to IOT
Hi,
My Oracle version is 10.2.0.4
Below is my structure of my test_table .
It has 1141580 rows.
I want to convert this into index Organized table. It has no secondary indexes.
How can I convert an existing table to IOT.
CREATE TABLE test_table (
Column1 NUMBER NOT NULL,
Column2 DATE NOT NULL,
Column3 VARCHAR2(100) NOT NULL,
Column4 VARCHAR2(8) NULL,
Column5 VARCHAR2(40) NOT NULL,
Column6 VARCHAR2(3) NULL,
Column7 NUMBER NOT NULL,
Column8 NUMBER NULL,
Column9 VARCHAR2(32) NULL,
ALTER TABLE test_table
ADD CONSTRAINT test_table_pk2 PRIMARY KEY (
Column1,
Column2
USING INDEX
STORAGE (
INITIAL 30720 K
ALTER TABLE test_table
ADD CONSTRAINT test_table_cons1 FOREIGN KEY (
Column1
) REFERENCES test_table2 (
Column1
/alter table doesn't allow to change the organization of a table.
So the logical answer to your question is
You can not
and your question
redundant.
As most other questions here.
So the answer should have been
- create a new table
- insert all rows
- drop the old table
- rename the new table
Oracle is not about rocket science.
Oracle is about reading documentation and using brains.
If you do that, maybe, one day, you will be a bigboy.
If you keep asking redundant questions you will remain a littleboy.

How to create a table from an existing table with new column
Hi !
Please help me.
I want to create a table from an existing table with data and add two new column to the new table.
What will be the syntax?craete table new_table as select a.*, 'somevalue' new_col1, 'somevalue'
new_col2 from old_table a;Also there is a pitfall - newly created table will accept column type and precision from the select statement, so further you can be needed to modify columns
if you want to have VARCHAR2 instead of CHAR for example:
SQL> create table new_dept as select dept.*, 'New data' new_col from dept;
Table created.
SQL> desc new_dept
Name Null? Type
DEPTNO NUMBER(2)
DNAME VARCHAR2(14)
LOC VARCHAR2(13)
NEW_COL CHAR(8)
SQL> alter table new_dept modify (new_col varchar2(8));
Table altered.
SQL> desc new_dept
Name Null? Type
DEPTNO NUMBER(2)
DNAME VARCHAR2(14)
LOC VARCHAR2(13)
NEW_COL VARCHAR2(8)Rgds.
Didn't see michael's post - it reflects the fix for this problem using CAST.

How to add a new data element for existing table filed(Primary key field)
Hi Experts,
How to add a new data element for existing table field(Primary key field)
For this filed ther is no foreign key relation ships and even check table.
while activating table it is giving message like below.
can you help any one to solve this and wil steps to add new dataelement for existing primary key filed of a table.
Check table (NAMING SPACE/TABLE NAME(EX:/TC/VENDOR)) (username/19.02.10/03:29)
Primary key change not permitted for value table /TC/VENDOR
Check on table /TC/VENDOR resulted in errors
Thanks
RaviHi,
Easiest way is to download the table eg into an Excel table (if possible) or text table. Drop the table from the database. Build your table with the new key field. Build the database table again and fill it.
You can do it also over the database into a new table. Drop the old one. Build the enhanced one and fill it. Afterwards drop your (temporary) table.
Maybe there are other ways, but this works.
Success,

Loading data from .csv file into existing table
Hi,
I have taken a look at several threads which talk about loading data from .csv file into existing /new table. Also checked out Vikas's application regarding the same. I am trying to explain my requirement with an example.
I have a .csv file and I want the data to be loaded into an existing table. The timesheet table columns are -
timesheet_entry_id,time_worked,timesheet_date,project_key .
The csv columns are :
project,utilization,project_key,timesheet_category,employee,timesheet_date , hours_worked etc.
What I needed to know is that before the csv data is loaded into the timesheet table is there any way of validating the project key ( which is the primary key of the projects table) with the projects table . I need to perform similar validations with other columns like customer_id from customers table. Basically the loading should be done after validating if the data exists in the parent table. Has anyone done this kind of loading through the APEX utility-data load.Or is there another method of accomplishing the same.
Does Vikas's application do what the utility does ( i am assuming that the code being from 2005 the utility was not incorporated in APEX at that time). Any helpful advise is greatly appreciated.
Thanks,
AnjaliHi Anjali,
Take a look at these threads which might outline different ways to do it -
File Browse, File Upload
Loading CSV file using external table
Loading a CSV file into a table
you can create hidden items in the page to validate previous records before insert data.
Hope this helps,

Add a new field to existing Table
Hi , We want to add a new field to existing table from ECC and populate historical data .
We have already extracted data from ECC to VBAK Table . We have to add a new field - Incoterms in HANA . This field exists in ECC .
Please guide.Hi Vicky,
I dont think you can add new fields to the condition table once you have activated the condition table.
SAP says you can only make limited changes to the condition table, like changing the description, fast entry screen, header and footer fields, but not able to add new fields to the table, and I think that is the correct approch or else for the same table you will have two sets of condition records.
Please refer to the below link:
http://help.sap.com/saphelp_erp60_sp/helpdata/en/de/7a8534c960a134e10000009b38f83b/frameset.htm
What you can do is create a new condition table with additional field and assign this table before the currently used table in the access sequence.
Hope this helps.

User-defined field in existing table
Hello,
I would like to know if it is possible to add a user-defined field in an existing table.
Actually, I would like to add a combobox with other types of partners than vendors, customers and leads and add a user-defined field in the OCRD table.
Thank you
Regards,
ThibaultHello,
Your answers help me a lot !
My code is working, i.e. when I create a new BP and choose another type in my comboBox, the information is saved.
When I search a BP who has this type, SAP find the good BP.
But, I don't see where the data is stored, I don't see anything which make the difference between 2 BP with 2 different types in the OCRD table.
So, where SAP can make the difference?
Thank you
Regards,
Thibault

Implications of adding new key fields to existing table
Hi All,
I have searched forum regarding this. But didn't find exact answer.
We are planning to add new key fields to existing Ztable. I want to know the implications of this.
I have checked the where used list of table and found no impact. Only one point is making me to think again and again.
If we add key fields to existing table then we have to adjust the table from SE14 to activate it. But this adjustment doesn't ask for TR.
So if i release my TR, entries in other systems will also be adjusted accordingly??? Business is OK with the new fields values to be blank for existing entries.
Thanks,
Vinod.Yes the data in transported systems will also be adjusted. If this table contains too much data make transport at late hours because it will take long and table can't be used while it's adjusted. In this adjustment process data is copied to a temporary table and moved back to original table using move-corresponding command after key added. There will data loss if you remove a key or key fields field length but in your case it shouldn't be a problem.

Datapump : How to append data in an existing table
Hello Everyone,
We are new to Datapump.
We try to extract data from one user/schema and to append it into another user/schema.
First we tried Tt use the parameter table_exists_action=append during the importation but we receive this error (but the rows are appended):
ORA-39152: Table "XXXXX"."YYYYY_ZZZ" exists. Data will be appended to existing table but all dependent metadata will be skipped due to table_exists_action of append
Which I don't expect since the utility have been told to, indeed, append data.
Next we tried to use CONTENT=DATA_ONLY on exportation and importation but the importation never end.
How can we append data into a table's user/schema without having an error?
Best regards.
CarlIGNORE=Y during the import.it does the same operation. if the table already exists,it ignores and proceed with importing/appending data to the tables. same way, they do have indexes=n and constraints=n option.
both export/import have equivalent options for fitering to our requirement and datapump has one step above classic import in which you can filter upto metadata object as well. -
How to insert columns in an existing table?
iv read the tutorial in this site http://www.w3schools.com/sql/sql_alter.asp but it is not for SQL Server 2000 DB.
Im using SQL Server 2000 DB. how do i insert column in an existing table?
i tried to execute the code (String query) below but it doesn't wrk:
For data type char:
String query = "ALTER TABLE [dbo].["+tablename+"] ADD [columnname] [char] (60) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL";
For data type int:
String query = "ALTER TABLE [dbo].["+tablename+"] ADD [columnname] [int] NOT NULL";________________________
is what's wrong with the code?Best solution would be to look up the exact syntax from the SQL Server 2000 documentation. The tutorial you have there teaches the ANSI Standard SQL. It is surprising that SQL Server 2000 (Microsoft right?) doesn't comply with that (especially since they list it in as one of the ones the tutroial was made to demonstrate).
I would double and triple check your sintax, whatch your error logs to make sure something else isn't preventing you from changing, and making sure you are logged in to the DB as a user who has the ability to alter tables. -
