• ORA-00936: missing expression when adding virtual column

  I am having this error when you add virtual column am in database 11 g

  Adding a column of Table virtual: example, the following statement adds a copy of the hr.employees table a column named income , which is a combination of salary more commission. Wages and the commission are NUMBER columns, so the database creates the virtual column as a NUMBER same column if the data type is not specified in the statement:

  CREATE TABLE emp2 AS SELECT * FROM employees; ALTER TABLE emp2 ADD (income AS (salary + (salary*commission_pct)));

• Addition of virtual column: ORA-12899: value too large for column

  I am using Oracle 11g, OS Win7, SQL Developer
  
  I'm trying to add the virtual column to my test table, but get ORA-12899: value too large for column error. Here are the details.
  Can someone help me in this?
  

  CREATE TABLE test_reg_exp
  (col1 VARCHAR2(100));
  
  INSERT INTO test_reg_exp (col1) VALUES ('ABCD_EFGH');
  INSERT INTO test_reg_exp (col1) VALUES ('ABCDE_ABC');
  INSERT INTO test_reg_exp (col1) VALUES ('WXYZ_ABCD');
  INSERT INTO test_reg_exp (col1) VALUES ('ABCDE_PQRS');
  INSERT INTO test_reg_exp (col1) VALUES ('ABCD_WXYZ');

  ALTER TABLE test_reg_exp
  ADD (col2 VARCHAR2(100) GENERATED ALWAYS AS (REGEXP_REPLACE (col1, '^ABCD[A-Z]*_')));
  
  SQL Error: ORA-12899: value too large for column "COL2" (actual: 100, maximum: 400)
  12899. 00000 -  "value too large for column %s (actual: %s, maximum: %s)"
  *Cause:    An attempt was made to insert or update a column with a value
             which is too wide for the width of the destination column.
             The name of the column is given, along with the actual width
             of the value, and the maximum allowed width of the column.
             Note that widths are reported in characters if character length
             semantics are in effect for the column, otherwise widths are
             reported in bytes.
  *Action:   Examine the SQL statement for correctness.  Check source
             and destination column data types.
             Either make the destination column wider, or use a subset
             of the source column (i.e. use substring).

  When I try to, I get the correct results:
  

  SELECT col1, (REGEXP_REPLACE (col1, '^ABCD[A-Z]*_'))
  FROM test_reg_exp;

  Thank you.

  Yes, RP, it works if you give col2 size > = 400.

  @Northwest - could you please test the same w/o having a clause of regex in col2?
  I have a doubt about using a REGULAR expression in this case Dynamics col.

  Refer to this (might help) - http://www.oracle-base.com/articles/11g/virtual-columns-11gr1.php
  Below excerpt from above link... see if that helps...

  Notes and restrictions on the virtual columns include:

  The indexes defined on the virtual columns are equivalent to a function-based index.
  Virtual columns can be referenced in the updates and deletions WHERE clause, but they cannot be manipulated by DML.
  The tables containing virtual columns may still be eligible for result caching.
  Functions in expressions must be deterministic when the table is created, but can then be recompiled and non-deterministic without for as much invalidate the virtual column. In such cases, the following steps must be taken after the function is recompiled:
  Constraint on the virtual column must be disabled and re-enabled.
  On the virtual column indexes must be rebuilt.
  Materialized views that access the virtual column must be fully refreshed.
  The result cache must be flushed if the virtual column acceded to the request (s).
  Statistical table must be regathered.
  The virtual columns are not supported for the organized and external object in index, cluster or temporary tables.
  The expression used in the virtual column definition has the following restrictions:
  It cannot refer to another virtual column by name.
  It can refer to the columns defined in the same table.
  If it refers to a deterministic user-defined function, it cannot be used as a partitioning key column.
  The result of the expression must be a scalar value. It cannot return that an Oracle supplied the data type, a type defined by the user, LOB or LONG RAW.

  Thanks a lot for the update of this old question
  After reading the link, I think I should ignore this error and accept him as ORA-01402

  The information that you have asked me to check me do not have an understanding of the different error types.

  Coskan,

  I didn't know this is an old thread that somehow got updated by someone else.

  Regarding your question: you're right that the output of the script is not really that useful.

  I have just run on 10.2.0.4 and in general, it seems that the output of USER_UPDATABLE_COLUMNS is incorrect regarding the views of join using the WITH CHECK OPTION.

  For example although the location_id from the TEST_V_2 column appears as non-editable (probably because of the rule that "the columns used in the join expression" cannot be modified in a join view when you use the WITH CHECK OPTION) I can run successfully your insert if statement I choose a location_id less than 2000.

  It seems that summed up the difference if you join more than two tables, you'll always get the error "ORA-01733" when you try to insert in the join with the enabled OPTION CHECK view. For example to add a third table TEST_V_2 which does not change the original view, but simply joined meaning for example COUNTRIES to LOCATIONS, will show the same behavior to throw an ORA-01733, however it works fine when the omission of the WITH CHECK OPTION.

  So overall, I tend to say it is really a limitation of the implementation and it is not actually an ORA-01402 but looks like Oracle is simply trying to tell you: Amendment No. INSERT in this possible view. Updates however seem to work, at least I can find some examples of work.

  There seems to be other restrictions of implementation with the WITH CHECK OPTION in place even when the only membership as two tables, for example when trying to join the COUNTRIES and PLACES but by selecting only in PLACES and by using a filter on the COUNTRY_ID predicate fails with ORA-01733 when this predicate is applied to the COUNTRY. COUNTRY_ID but it works if this predicate is applied to PLACES. COUNTRY_ID.

  I could imagine that Oracle has quietly added some of these restrictions with each patch set due to the angle of the case/adverse reactions encountered. I saw this for other features, too.

  Kind regards

  Its simple you used SEPARATE in your first view inline. And so you cannot use columns for UPDATE.

  Hello

  Review the syntax for virtual columns in the manual of the SQL language:
  http://download.Oracle.com/docs/CD/E11882_01/server.112/e26088/statements_7002.htm#sthref5146

  You want something like this (showing only the relevant columns):

  CREATE TABLE DTPartInv
  (
       partinv_instock          INTEGER          NOT NULL
  ,     partinv_reorder          INTEGER          NOT NULL
  ,     partinv_flag           VARCHAR2 (1)      AS ( CASE
                                          WHEN  partinv_instock < partinv_reorder
                                         THEN 'X'
                                            ELSE 'O'
                                      END
                                   )
  );
  
  INSERT INTO DTPartInv (partinv_instock, partinv_reorder) VALUES (100, 100);
  

  Announcing the column names until the VALUES of Word key is a good idea in any case, and it is needed when you have virtual columns.

• Interval partitioning using the key of the virtual column

  Hi guys

  I have a series of tables that I propose to the partition.

  Each table has a year and a period (equivalent to a month) and I intend using those as my partition keys - year as the partition and the period as the subpartition.

  The distribution will be actually:

  2015

  001

  002

  ...

  012

  2016

  001

  002

  ...

  012

  etc...

  I would use range partitioning for the year, because it would make the maintenance of the partition a breeze.  Only one problem - the field is of type varchar, and is not modifiable as its legacy applications that have become bigger than Ben Hurr and more tangled than a Ben Hurr size flat spaghetti.

  It is hence the idea of virtual column between in game - I could create a virtual column in these tables to convert the field to digital and then partition on it instead.

  My question-if the year of origin varchar column is included in the where clause of a query, is the optimizer based on CSSTidy smart enough to realize that the virtual column used for the partition key is based on this column and use pruning of partition to improve performance?  Or queries must refer to the virtual column to make it work?  Also, the virtual column should be indexed to make it work?

  Thanks in advance.

  Hello

  Reason is the primary key of the table that is assigned prodid, mgrid, but you try to create the foreign key columns separately.

  Try which follows and this should work:

  CREATE TABLE QUALITYCHECK (
    prodid number (4) CONSTRAINT NN_ALLOCATION_prodid NOT NULL,
    mgrid number (4) CONSTRAINT NN_ALLOCATION_mgrid NOT NULL,
    weekno number (2),

• json_list to varchar/string to use in the virtual column

  Hello Experts,

  Environment:

  Database Oracle 12 c Enterprise Edition Release 12.1.0.2.0 - 64 bit Production

  PL/SQL Release 12.1.0.2.0 - Production

  I have the following function that returns JSON_LIST.

  {code}

  CREATE OR REPLACE FUNCTION GENERATE_JSON (STRING2CONVERT IN VARCHAR2)

  RETURN JSON_LIST

  DETERMINISTIC

  IS

  RET json_list;

  V_ERROR VARCHAR2 (31000);

  BEGIN

  RET: = json_dyn.executeList (STRING2CONVERT);

  RET. Print;

  RETURN RET;

  EXCEPTION WHEN OTHERS THEN

  V_ERROR: = SQLERRM;

  RETURNS A NULL VALUE.

  END;

  -test the query see the output in the output of DBMS

  SELECT GENERATE_JSON (' select ' |) Chr (39) | ' AJ' | Chr (39) |' like c_name,' | Chr (39) | ' BOY ' | Chr (39): ' c_type, like '

  || Chr (39) | ' HUMAN '. Chr (39): ' as c_category,' | Chr (39) | ' TEST SUBJECT ' | Chr (39) | 'as c_desc from dual')

  FROM DUAL;

  
  

  {code}

  
  

  The SQL query above in the DBMS output output

  [{

  "C_NAME": "AJ."

  "C_TYPE": "BOY."

  "C_CATEGORY": "HUMAN."

  'C_DESC': 'GUINEA PIG '.

  }]

  
  

  Question: How can I have it return the same structure of String (varchar).
  

  
  

  Why would I want to convert JSON_LIST to string?

  So that I can use this call to service as part of a virtual column in a table to store Json and have a constraint to enforce structureof Json.

  
  

  If this is not the right way?

  Kindly share how I can take a few columns in the same table, convert to json format and store in a virtual column in the same table and enforce the Json structure?

  
  

  Thank you

  Why you use double?  Why not just

  UPDATE tab1

  SET of notes = REPLACE (notes, v_note2)

  WHERE file_id = 1

• I want to change the table with the expression of dangerousness of the virtual columns with her, need advice

  Hi all

  Here is the structure of the table with two expression of virtual columns associated highlighted, now I want to delete these expressions with virtual columns (but must keep my VIRTUAL columns as it is).

  Is it possible the alter or I need to raise the table, make a new structure and copy content back to newly structured table... Pleae help!

  CREATE TABLE TEST_COL)
