• length of the data type of a column

  Hello
  
  I would like to know if it is possible to find the length of the
  data type in a create table stmt.
  
  For example:
  create employee table (empno number (3), empname varchar (10));
  
  
  in the DDL above I mentioned the size of my 3 number data type.
  is there a way to retrieve this info. ?
  outside desc < table_name >?
  
  
  Thanks in advance

  SQL> create table employee(empno number(3),empname varchar(10))
    2  /
  
  Table created.
  
  SQL> select column_name

• Column data type not supported

  Hello

  I have Oracle 12 c installed in my system. I created an SP that returns a Table when I try to run it in SQL Developer, it gives me the correct results, but when I call it my DOTNET application it gives me the error-'datatype of the column unsupported. I'm trying to fill a dataset using a data adapter. To check I commented all the code in the procedure and returned the table using the code below.

  Declare
  rc sys_refcursor;
  Begin
         OPEN rc FOR SELECT 'Sayam' AS "Error" FROM dual;
         SYS.DBMS_SQL.RETURN_RESULT (rc, TRUE) ;

• XMLTable: definition of the columns data type of table

  Thank you.

  Specification of column names is required, but you can omit the declaration of data types.

  See: the function XMLTABLE SQL/XML in Oracle XML DB

  XMLTable is used with storage XML based on a schema of XMLType data type is optional. If absent, the data type is inferred from the XML schema. If Oracle > XML DB is unable to determine the right type of a node, a default type VARCHAR2 (4000) is used.

  It is an Oracle extension; in the SQL/XML standard, the data type is always required.

  Note:
  The alleged data type might change as a result of the application of a patch or upgrade of Oracle XML DB. In particular, a new set of release or patch might be able to > determine the data type when the previous version was unable to do so (and therefore not reimbursed to VARCHAR2 (4000)). To protect against such an eventuality, specify an explicit data type with the data type.

• Database application - direct incorrect column data type

  Hello all-
  
  hope you can help with this. I use the live database request in Oracle BI to send a complex query directly to our data warehouse. My problem is that the columns of results containing my measurements are converted by Oracle BI so they should be double. The conversion of integer causes decimals to round values, reading to incorrect results in my reports. I tried several tweeks to my request to allow OBIEE correct estimate on the data type, but nothing has worked.
  
  Is there a way to force OBIEE to recognize the correct data type for a column in a query request to the live database?
  
  Thanks in advance for you help!

• Timestamp for date columns data type are not imported in discoverer admin

  Hi all
  Someone you will suggest why timestamp data type columns are not imported into admin. discoverer other types of data import you correctly, but the timestamp data type columns are missed.
  
  Please let me know to change the type of data is not possible at this time.
  Thank you

  Hello
  You will be disappointed because the timestamp columns are not one of the recognized data types supported by the discoverer. He acknowledges only dates, strings and (integer and decimal) numbers.

  Maybe you could put up a view that matches the table you use, convert the timestamp in a rather ordinary date?

  Then, inside your end-user license, all you would have to do is redirect the folder to view.

• ODI 12 - problem with missing data in the store column data types

  Hello world

  We have recently installed Studio 12 on Oracle RDBMS ODI. We have created some topologies, contexts and the logical architecture. We have created the necessary templates and made reverse engineering. The strange thing is when a model data store opening, we have noticed, the data types of its attributes are not displayed and cannot be selected in the drop-down list because they do not exist yet. You can see the image below.

  

  So the mappings are not correctly executed because on the stage of the creation of work tables CREATE script was not generated correctly. (It's something like "CREATE TABLE < name > ()")

  Anyone can give an idea what could be the reason for this and how might be solved?

  Any ideas would be appreciated.

  Thank you in advance.

  There is no link between "chose an incorrect key SP2-0552: Bind variable undeclared" B0"AND"LONG tables of data type"both are different results, there are two distinct sqls are executed in the database for"# Tables with constraints of payment deferred"AND"# Tables with CLOB, BLOB, LONG, NCLOB or LONG RAW columns in all schemas.

  # - These symbols are used for each query result comment line.

  This means,

  # Tables with constraints of deferred payment. Deferred constraints can cause TRANDATA to choose an incorrect key SP2-0552: Bind "B0" undeclared variable.

  no selected line

  # Tables set with the size of > 2M line in all schemas

  no selected line

  # Tables with number primary key or a Unique Index and length 1 M column >

  no selected line

  # Tables with CLOB, BLOB, LONG, NCLOB or LONG RAW columns in all schemas

  THE DATA OWNER TABLENAME TYPE
  PR_COLLMAIN ALLOC_TEST LONG
  PR_COLLMAIN BOD_TEST LONG

  If you open this file and read 'full - DB_CheckOracle_12072011.sql' you can see the sqls separated for each control and output results.

  Finally, there are no Tables with constraints carried forward in your database that will impact Trandata.

• Subtype and data types

  Hi all
  
  We can overload subprogrammes that setting differ in the number, order, and type of family data. But impossible to overload if the parameter differs only in the void type.
  
  If I see the standard package, I get
  subtype types BINARY_FLOAT is NUMBER;
  subtype BINARY_DOUBLE is NUMBER;
  
  But I am able to overload the two procedures, we have a parameter types binary_float and binary_double other. They are of subtype of the same data type. that is the number. So, how is it possible. Also, most of the subtypes have no difference. So, why are there these number of subtypes? Oracle defines subtypes as data type with some sort of constraint on the base data type, but is valid for all? for example, smallint, and decimal.
  
  type of NUMBER is NUMBER_BASE;
  subtype of FLOAT is NUMBER;
  ACTUAL subtype is FLOAT;
  subtype 'DOUBLE PRECISION' is FLOAT;
  INTEGER subtype is NUMBER (38.0).
  subtype INT is INTEGER;
  subtype SMALLINT is NUMBER (38.0).
  DECIMAL subtype is NUMBER (38.0).
  DIGITAL subtype is DECIMAL;
  DEC subtype is DECIMAL;

  Some of those who, as a smallint, SQL ANSI data types. See table 2-6 ANSI Datatypes converted to Oracle data types in the doc of the SQL language
  http://docs.Oracle.com/CD/B28359_01/server.111/b28286/sql_elements001.htm

  Oracle allows the name of the ANSI data type to use and combines the name of the ANSI for the appropriate Oracle data type

  ANSI SQL/DS and DB2 data types

  The SQL statements that create tables and clusters allows also ANSI data types and products IBM SQL/DS and DB2 data types. Oracle recognizes the ANSI or IBM data type name that differs from the Oracle database data type name. It converts the data type for the equivalent Oracle data type, stores the Oracle data type under the name of the column data type and stores the data in the column in the data type Oracle based on the conversions listed in the following tables.

  But BINARY_FLOAT and BINARY_DOUBLE types are each defined as unique data types (see table 2-1 in this doc).

  Because they are unique Oracle data types, they can be overloaded.

• Change the length of a Table column (CHAR data type)

  Hi gurus,

  SQL > select * from version $ v

  BANNER

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

  Oracle Database 10g Release 10.2.0.3.0 - 64 bit Production

  PL/SQL version 10.2.0.3.0 - Production

  CORE Production 10.2.0.3.0

  AMT for Linux: release 10.2.0.3.0 - Production

  NLSRTL Version 10.2.0.3.0 - Production

  I need to increase the length of a CHAR of a table data type column (currently it's tank (3) and you want to change to char (4)). Here are more details on the table:-

  • Contains more than 20 million lines.
  • Table contains several indexes.
  • Table is referenced by several tables (about 60 tables) and it refers to several tables (about 3)
  • Table has 4 complex triggers. Triggers call procedures and packages.

  What I've tried so far

  
  

  1 disabled all triggers and ran ALTER statement to increase the length. It took hours and did not finish in a reasonable amount of time, even if no error, but it took more than 12 hours.

  2 tried DBMS_REDEFINITION package but it does not work with the standard version of Oracle 10 g.

  I think to try next

  I think same Optics:

  Say my name of the existing table is OLD_T1 where the length of column need to increase

  -Create a copy (with increased column length) table of OLD_T1, Say NEW_T1

  -Move data from in OLD_T1 to the new table NEW_T1

  -Lower OLD_T1 (or rename it to OLD_T1_TMP)

  -Rename NEW_T1 to OLD_T1

  -Create all indexes, triggers, constraints etc..

  I wish to confirm, if my approach is correct? Or someone has a better idea to do this?

  Please note: I know that the CHAR data type gives the problem but it is an old system and I don't have authority to change the design of database.

  Appreciate any comment/suggestion

  Thanks in advance

  > I mean, can any application break if it depends on fixed-length?

  Yes, because the code can be expected completed on the right areas.
