• ALTER table - column required

  Hey guys, quick question. I have a table that is created and that you just want to make one of the columns is required. What is this done by following these steps:
  
  ALTER TABLE < my_table >
  ALTER COLUMN < my_column > MANDATORY
  
  If this isn't the case, could someone guide me on how to do it.
  
  Thank you.

  There is no LIMIT to the 'free' version  If you read the error message he said THAT was not a valid identifier.  Just to show you that I tried your erroneous statement

  ALTER TABLE hf_altertest ADD COLUMN state2 CHAR(2);
  

  and here is the indicator error message in SQL +.

• ALTER Table Add column not null, no default

  I want to add two columns in a table with not null, and the default value 0 for two columns
  Can I write everything in a single statement or do I have to divide the declaration
  I tried, but didn't work
  
  ALTER table DWSODS01. DWT00301_ORD_DTL_OMS add)
  COMB_ORD_FLG NUMBER (5.0) default null, 0

  How can I change the code?

  user10390682 wrote:
  OK, so if it is NOT NULL, while there should be a value.

  Yes.

  So, when I set these two columns as NOT NULL will only future data must be NON NULL.
  What of the old and present data if I defined as NOT NULL

  NOT NULL mean value of eachcolumn + line (current or future) _ must not be null. That's why always adding NOT NULL column to a non-empty table fails - the column value for existing lines will be NULL which does NOT violate the constraint nullability. If you add the NON NULL column with a default value, the column will be added and all lines existing column value will be defined by specified default (0 in your case). As a result Oracle will be able to settle forced to null for this newly added column from the value of this column in all the existing lines will be not not null (0 in your case).

• Quick question: alter table, alter column NOT NULL...

  Hey all,.
  
  If I change 3 populated (they have data) columns in a table with about 300 million of NULL lines that is NOT NULL:
  
  alter table blah
  change (col1, col2, col3 NOT NULL NOT NULL, NOT NULL);
  
  ... about cela "will take a long time?
  
  I know that it is a question REALLY of high level, but I wonder how long it should consume (a few minutes or several minutes - looking for an approximate answer as well). The table has 10 columns, if that helps.
  
  Hardware specifications are not relevant... I am looking for a basic response.

• Generate the DDL - change is a new column and I want to generate an alter table.

  All, morning
  
  I searched and searched all over the Data Modeler and I can't find this option... but I found it easily in the designer.
  I hope you can help me.
  
  V3.0.0.665 SQL Developer Data Modeler.
  
  I added a new column to a table, and when I generate the DDL I wish it were an alter table add column rather than a table to create.
  This feature is in the designer, so I think it would be in the Data Modeler.
  
  Just in case my description isn't clear, here are the high level steps, then it is clear.
  
  1 create logic model
  2. create the relational logic.
  3. create the physical relationship.
  4 generate the DDL and run in the database. At this point, I'm going to production with my system, and all right.
  5. at this point, we have an enhancement request. For the model, it will be a new column in a table.
  6. update of the logic model.
  7. relational update logic
  8 physical update of relational
  9 generate the DDL. Here, I would have generate it know that it needs to generate an alter table add column and does not create the table.
  This is something I do a lot as all my models are in production. I can't find how to do this step to get data Modeler to generate the altar.
  Designer done exceptionally well.
  
  Quite often, it is more than a single column. Changes can be many and made over time and at the time of generating the DDL you remember not every single amendment. To have the tool discover these changes for you and generate the appropriate DDL is a feature that I consider as very high.
  
  I hope that is clear and you can help me.
  
  See you soon
  Chris...

  Hi Chris,

  you need to compare your model on database - database relational model even import and use the option 'swap target' - in this case 'expressions of alter' against the database will be generated.
  You can watch demonstrations here http://www.oracle.com/technetwork/developer-tools/datamodeler/demonstrations-224554.html
  It would probably be more useful http://download.oracle.com/otn_hosted_doc/sqldev/importddl/importddl.html
  Sooner or later your changes will require the table to be recreated, and you will need to backup your data - you can consider using the 'Advanced DDL' option - script is generated that will land your table content (including LOBs) to the system of files accessible from the database and restore after changes. Well not try directly on the production system :).

• ALTER TABLE SHRINK the SPACE COMPACT takes a long time

  Hello
  I run:
  ALTER TABLE TOM. TAB1 SHRINK SPACE COMPACT;
  ALTER TABLE TOM. TAB1 SHRINK SPACE WATERFALL;

  
  The "ALTER TABLE TOM. Tab1 SHRINK SPACE COMPACT"was completed in 2 hours, but"ALTER TABLE TOM. Tab1 SHRINK SPACE WATERFALL"is still underway after 8 hours, less than the size of the table TAB1 and index:

  NOM_SEGMENT... GB
  TAB1................................. 166
  IDX01................................ 83
  SYS_C00......................... 42
  IDX02............................. 142
  IDX03.............................. 66
  IDX04............................. 122

  
  Why 'SHRINK the SPACE COMPACT' takes a lot of time?
  Is it possible to check how much time should I take?

  Thanks in advance!

  Running

  ALTER INDEX TOM. TAB1_IDX03 SHRINK SPACE COMPACT;

  ALTER INDEX TOM. TAB1_IDX03 SHRINK SPACE;

  set is useless, as does 'SHRINK the SPACE' that means "SHRINK SPACE COMPACT" and much more (see the quote from the Doc Oracle Hemant).  2, 'SHRINK the SPACE' is the operation that will take more time.  So if 'SHRINK the SPACE' is what you wanted (reclaim space) and you can afford to wait, run 'SHRINK the SPACE' only.

  "SHRINK the COMPACT SPACE" is a part of the work that 'SHRINK the SPACE' is only.  Generally, use you it when time is at a premium: you run SHRINK SPACE COMPACT a weekday evening (because SHRINK the SPACE does not fit in one night and accrue hourly) and you run SHRINK SPACE on the weekend to finish following the recovery of your space.

  Regarding the fact that the entire segment or a partition after another, I have no experience - I both of their time and test methods.  Perhaps running several sessions at the same time on different partitions would save time (but be more heavy on the CPU and storage).

  Also note that SHRINK the AREA generates a lot of REDO (keep an eye on the free space of your ARCHIVELOG destination).  With your data volume, I would expect dozens (or even hundreds) of gigabytes of roll forward must be generated.

• ALTER TABLE RETRACTABLE is possible online?

  RDBMS Version: 11.2.0.4

  Platform: Oracle Linux 6.4

  We have a database of CARS of Production 2 nodes very critical. To recover the space, we want to cut some large tables. The first table we'll shrink is a 300 GB, which is not partitioned with no LOB table.

  Here are the steps that we'll run.

  Step1.alter mytable table allow the movement of the line;

  Step2.alter mytable table shrink space compact;

  Step3.alter mytable table shrink space;

  Step4.alter table mytable disable the movement of the line;

  STEP 5. COLLECT STATISTICS of the table (because the RETRACTABLE table will cancel all the sliders in the shared pool)

  The steps above will take at least 10 hours to complete a 300 GB table. We would like to know if all of these steps can be done online. That is to say. We do not want the SHRINK command to lock the table and prevents the table to be modified (any DML) by the application

  Doc below said this can be done online. But, MOS DOC 1357878.1 said that it is not and you must use the DBMS_REDEFINITION package if you want to do it online.

  https://docs.Oracle.com/CD/E18283_01/server.112/e17120/schema003.htm

  The MOS article you are talking about is not correct. Outside the DOF at the end of a SHRINK lock when the high tide is shifted, SHRINK the SPACE is an online operation. DBMS_REDEFNITION is actually worse because you have DDL locks at both the beginning and the end. However, in both cases, it is the DDL that is blocked by other operations DML (and not the other way around) so that your users will have no problem. If the narrowing or the redefinition is blocked, you can suspend the database for a few seconds. I described how to do here,

• Online syntax to create Foreign key with Alter Table statement

  I am a pretty meticulous reader. That being said, from the 4 texts that I read to start to learn SQL, I do not remember and do more that probably not, find a syntax online for the creation of a CF with the statement alter table.

  Just something I thought while I was reading.

  Is there a such syntax?

  And if so someone can give me direction on my code?

  ALTER table emp4 change employee_id key foreign employees of references (employe_id);

  It gives me the option error invalid alter table.

  Any idea would be appreciated.

  Thank you.

• alter table drop column

  Hi all

  I create a simple table like this:

  create table x (a number, b varchar2 (20));

  ALTER table x modify a primary key constraint a_pk;

  insert into x values (1, 'first row');

  insert into x values (2, 'second row');

  commit;

  Then:

  SQL > select * from x;

  A AND B

  ---------- --------------------

  1 first row

  2 second row

  Then I run these commands:

  SQL > alter table drop column x.

  Modified table.

  SQL > select * from x;

  B

  --------------------

  first row

  second row

  Question: Why am I able to remove this column when a PRIMARY KEY for the table? I do not use the key words of CONSTRAINT CASCADE with the DROP COLUMN clause...

  I have Mr. Steve O'Hearn here saying this in his book 'Certified Expert Guide exam 1Z0-047:

  CREATE TABLE ORDER_RETURNS

  (NUMBER OF ORDER_RETURN_ID,

  NUMBER OF CRUISE_ORDER_ID

  DATE OF CRUISE_ORDER_DATE,

  CONSTRAINT PK_OR PRIMARY KEY (ORDER_RETURN_ID));

  .. We can not remove the column the table ORDER_RETURNS that

  is subject to the constraint PRIMARY KEY (ORDER_RETURN_ID)... The reasons are:

  ORDER_RETURN_ID is the PRIMARY KEY of this table...

  Isn't this correct?

  No - it's NOT correct - the book is bad.

  You could have just tested the FULL example in the book to verify that the statement is wrong.

  http://weirdoootamee.yolasite.com/resources/Oracle%20sql%20expert.PDF

  See page 432

  CREATE TABLE CRUISE_ORDERS
  (NUMBER OF CRUISE_ORDER_ID,
  ORDER_DATE DATE,
  PK_CO (CRUISE_ORDER_ID, ORDER_DATE) PRIMARY KEY CONSTRAINT);

  CREATE TABLE ORDER_RETURNS
  (NUMBER OF ORDER_RETURN_ID,
  NUMBER OF CRUISE_ORDER_ID
  DATE OF CRUISE_ORDER_DATE,
  CONSTRAINT PK_OR PRIMARY KEY (ORDER_RETURN_ID).
  FOREIGN KEY CONSTRAINT FK_OR_CO
  (CRUISE_ORDER_ID, CRUISE_ORDER_DATE)
  REFERENCES CRUISE_ORDERS (CRUISE_ORDER_ID, ORDER_DATE));

  create two tables - add data, if you want.

  Then try to delete the primary key column and see what happends

  ALTER table drop column order_return_id order_returns;

  The best way to learn is to actuall TRY of THINGS.

  Try it with your own table, but the FIRST thing that you should try was the real example of the book.

• ALTER table add constraint vs alter table change

  Hello

  could someone explain why we have two different statements when you add a constraint on an existing table?

  If I need to add a primary key constraint to a column from an existing table that I use:

  ALTER table tab1 add the key primary constraint tab1_id_cst (id)

  But if I want to add a NOT NULL constraint, the same syntax does not work, I need to use alter table change instead

  Why?

  Thank you!

  Hello

  The constraint not null is a constraint inline, average, it applies to the column level. So in order to change anything at the column level you must use "ALTER TABLE CHANGE" only.

  Remaining constraint is forced to outline, which are part of the table definition. The table definition can be modified by "ALTER TABLE... ADD '.

  In the framework of the above mentioned constraints, those are the two columns level constraints and table except constraint NOT NULL value. Change column level, you must use the syntax

  and for the level of the table, you need to use the respective syntax.

  Kind regards

• ALTER TABLE with the column NULL time consuming

  Hello

  I have a table with nearly 2 million documents (about 10 GB size table) when I perform the following change statement its run fast

  ALTER TABLE tbl_1 ADD (DEFAULT col_4 NUMBER 100 NOT NULL);

  but when I do not give the NOT NULL in the alter its taking a long time to complete this i.e tbl_1 of ALTER TABLE ADD (NUMBER col_4 by DEFAULT 100); once I do the column as NOT NULL.

  Can someone explain why is it happening like that regarding the execution point.

  Thanks in advance.

  I can reproduce the effect in 11.2.0.1 - but not in 12.1.0.1.

  drop table tbl_1;

  create table tbl_1

  as

  Select rownum id

  , lpad ('* ', 50,' *') padding

  of the double

  connect by level<=>

  ALTER TABLE tbl_1 ADD (NUMBER col_4 by DEFAULT 100);

  --> slow in 11.2.0.1; fast 12.1.0.1

  ALTER TABLE tbl_1 ADD (DEFAULT col_4 NUMBER 100 NOT NULL);

  --> Quick 11.2.0.1 and 12.1.0.1

  A SQL trace for two operations (11g) shows that the altar slow (without the constraint explicit non-null) made explicit (and tedious) update of any row in the table:

  Update 'TBL_1"set"COL_4"= 100

  call the query of disc elapsed to cpu count current lines

  ------- ------  -------- ---------- ---------- ---------- ----------  ----------

  Parse        1      0.00       0.02          0          1          0           0

  Run 1 11,63 33.56 8336 1016125 2053531 1000000

  Fetch        0      0.00       0.00          0          0          0           0

  ------- ------  -------- ---------- ---------- ---------- ----------  ----------

  Total 2 11,63 33,58 8336 1016126 2053531 1000000

  The other trace file does not contain the explicit Update. I guess in the optimized case that oracle stores somewhere that col_4 has the value 100 and updates only the line of the block after completing DML operations. But that's just a guess.
