• Insert/update the column with the clob data type

  Hi all

  ORCL Version: 11g.

  I have a table with the clob data type.

  Test12

  (col1 clob);

  I'm trying to insert/update to update the column with more than 4000 characters.

  But due to the limitation of tank 4000, I could not Insert/Update.

  Need your help in resolving this issue.

  THX

  Rod.

  The limit of 4000 characters is incorrect.  That pertains only to the varchar2 data type.  A clob can hold more than 4 G.

  Here is an example that shows how to insert it, I found...

  Otherwise, here is a way 'dirty' to do.

  insert into your_table (COLA, COLB)

  values

  (PRIMARY_KEY, PART 1 OF DATA)

  ;

  Update your_table

  Define COLB = COLB | PART 2 OF BIG DATA

  where COLA = PRIMARY_KEY;

  Update your_table

  Define COLB = COLB | PART 3 OF BIG DATA

  where COLA = PRIMARY_KEY;

  .. and so on...

  I don't know that I personally recommend the second style...  But he could do the job.

  I'm looking to create a table based on another table that having the column long data type. Throw the error ORA-00997: illegal use of the LONG data type

  
  I tired it

  How to get there?

  I'm looking to create a table based on another table that having the column long data type.

  You really don't want to do that.

  LONG data type has been deprecated for some time now, use CLOB.

  The TO_LOB() function will do the conversion on the fly:

  create table abc_long_dummy

  select ag

  By the way I couln t understand what were you thinking when you explain to no.

  I missed you NVARCHAR2 column and thought it was VARCHAR2. When you declare the semantics of VARCHAR2 column length is specified explicitly or implicitly. Explicitly suffixing length with BYTE or CHAR and implicitly when you specify the length of the right itself. Then length is based on the value NLS_LENGTH_SEMANTICS session. So let's assume you generate table create statement (and it seems that you is, based on column_name |) » '|| DATA_TYPE | » ('|| ( data_length|') ' ). Then it does not matter if use use data_length or char_col_decl_length. It will be regadless semantics implied length of what you use. Therefore, when you run create table instructions column length will be interpreted as bytes if current NLS_LENGTH_SEMANTICS byte value. But same length is interpreted as the characters if current NLS_LENGTH_SEMANTICS a char value. As you can see, in order to generate create table statement we use explicit semantic length column, otherwise create table statement can produce lengths of different column in the source table.

• Largest number of digits for the NUMBER data type?

  What length more of a NUMBER that Oracle will "support"?

  The documentation says the following:

  Limitations of the data type says:

  «Can be represented in a comprehensive precision 38 digits»

  NUMBER of Data Types says:

  "Oracle guarantees portability of numbers with precision of up to 20 digits of base-100, which equals 39 or 40 decimal digits according to the position of the decimal point."

  I realize account that if I define a column as simply NUMBER, I can insert numbers with a size up to 126 characters.  However, Oracle seems to maintain only the first 40 digits in MOST cases.  The largest number of digits, it seems to allow is 40 before it begins to be replaced by 0.

  With numbers that have more than 40 figures, Oracle will sometimes replace all numbers according to the 38th numbers with a 0 and sometimes replace 0 after the digit 39th or 40th.

  Therefore, what is the largest number of digits, can be trusted to safely store Oracle?

  This is the code I used for this testing process.

  create the table max_num (num number);

  declare

  number of l_x;

  Start

  for x in 1.200

  loop

  l_x: = x;

  insert into max_num values (rpad (1, x, 1));

  end loop;

  exception

  while others then

  dbms_output.put_line ('STOP: ' | l_x);

  dbms_output.put_line (SQLERRM);

  end;

  /

  Select num, length (replace (num, 0)) of max_num;

  What length more of a NUMBER that Oracle will "support"?

  You have already given your own answer. If 'length': the maximum number of digits is written the doc gives you the answer:

  999... (38 9's) x 10 value maximum¹²⁵

  The 38/39/40, hereinafter referred to as the doc means "significant digits". This is why rounding or truncation occurs if you provide more significant digits of 38/39/40.

  Oracle stores the numbers internally in a binary format 21 bytes using a documented structure in the doc of the OIC in the section 'NUMBER'.

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e10646/oci03typ.htm#i423684

  Oracle database stores the values of the NUMBER data type in a variable length format. The first byte is the exponent and is followed by 1 to 20 mantissa bytes. The high bit of the exponent byte is the sign bit; It is defined for positive numbers, and it is cleared for negative numbers. The lower 7 bits represent the exponent, which is a number of base-100 with an offset of 65.

  This article from doc continues to show you how to convert the internal format to the real value.

  An additional byte of 1 is used for all types of data to store the length; That's why you often see docs saying numbers can take 22 bytes.

• How to use the LOB data type?

  correct syntax is

  Where is a name of the / columns LOB, not the name of the segment. Moving type LOB data will move its indexes as well.

• The wrong data type on bind variable

  We are testing framework entity with ODP.NET and linq to entities and have a little problem.
  
  We run a simple linq to entities statement with a variable binding and our problem is that the column in the oracle database is the CHAR type framework but entity sends the binding as NVARCHAR2 variable. This causes the oracle do not use the index on the column and a full table scan is performed.
  
  Entities are generated from the database.
  
  LINQ:
  public string Name (string value)
  {
  var object = (from s in ctx3. TABLE
  where s.COLUMN1 is value
  Select s.COLUMN2). ToList();
  Returns the object [0]. ToString();
  }
  
  Is there a way to set the data type for a variable binding when you use linq?
  
  Published by: 872217 on March 13, 2012 04:42

  Because the .NET string is in Unicode, by default, NVARCHAR2 is used in the binding of parameter to string variables.

  EntityFunctions.AsNonUnicode (of use) should be able to say ODP.NET you want to treat a non-Unicode string.
  In this case, VARCHAR2 should be used for the link.
  I hope this will save for you table scan when there is no conversion data more.

  using System.Data.Objects;

  public string Name (string value)
  {
  var object = (from s in ctx3. TABLE
  where s.COLUMN1 is EntityFunctions.AsNonUnicode (value)
  Select s.COLUMN2). ToList();
  Returns the object [0]. ToString();
  }

  Please let me know if it works for you.

• Cannot save the types of collection with the correct data type (structure type)

  Hi all!
  
  I am beginner in using the Data Modeler (SQL Develeoper Version 3.0.04 build HAND - 04.34)
  
  I tried to define types of structured data type type collection.
  
  for example
  Types of structure: StruA (for example, Integer, Float) and StruB (e. g. whole, Timestamp, Double, Double)
  Types of collections: TabA should collect the types of StruA and TabB should collect the types of StruB.
  
  create or replace TYPE TabA IS TABLE OF StruA;
  create or replace TYPE TabB IS TABLE OF StruB;
  
  It is possible to select the correct data type in the 'Collection Type properties' dialog box.
  
  The data type is installed to unknown after the registration and the reopening of the design. I see that the correct type has been entered in the xml file associated with the type of collection:
  < dataTypeDescr class = "oracle.dbtools.crest.model.design.datatypes.CollectionType$ DataTypeWrapper" >
  65677BBB-FB68-963C-552D-3F98E528520B < type > < / type >

  < / dataTypeDescr >
  
  File name of the structured type is 65677BBB-FB68-963C-552D-3F98E528520B.xml
  
  On the display of the design or generation DDL lose again this information.
  Is - this poor handling or a bug in the Data Modeler?
  Can anyone help? THX

  can someone help me
  
  Thank you

  You have changed your original post, so now I see that you get the invalid number.

  This is why you should always avoid the varchar columns to store numbers or dates...

  Since your table source contains a nonnumeric value, you can write a pl/sql to convert data and see what records are false:

  SQL> insert into a (col1,col2) values ('xxxx','2345');
  
  1 row created.
  
  SQL> select * from a;
  
  COL1     COL2
  -------- --------
  1234     2345
  xxxx     2345
  
  2 rows selected.
  
  SQL> create table b (col1 number(19), col2 number(19));
  
  Table created.
  
  SQL> set serverout on
  
  SQL> declare
    2  cursor c is
    3  select * from a;
    4  begin
    5    for r in c loop
    6     begin
    7       insert into b values (to_number(r.col1), to_number(r.col2));
    8     exception
    9       when invalid_number then
   10        dbms_output.put_line('Row rejected: col1='||r.col1||' col2='||r.col2);
   11     end;
   12    end loop;
   13  end;
   14  /
  Row rejected: col1=xxxx col2=2345
  
  PL/SQL procedure successfully completed.
  
  SQL> select * from b;

• convert the money data type in a decimal format 2.

  What is the best way to convert the money data type in a decimal 2 format in ms sql 2005 for use in my applications.

  This?

  CAST (tr.depositReceivedAmount AS decimal (10, 2))

  I respectfully disagree with the idea that you must change the query column a type of 'money' data to something else.

  In most database servers, "«argent» Silver" is a data type that is designed to provide a very homogeneous behaviour with regard to the arithmetic accuracy.  In Microsoft Access, the representation is a the whole scale.  MS SQL Server, it is obviously similar.  Ditto Oracle and others.

  You like that the money data type in the database for this clarification, because "hell has no fury like an accountant looking for a bad penny."   The column of database storage formats are designed to satisfy the accountants, and it's a good thing.

  Meanwhile, you also want to take care as to exactly how you are dealing with values.  There are several points where the district could take place.  You don't have available the strongest possible manipulation of the floating of the data types in ColdFusion.  You also are somewhat at the mercy of any interface software can be between you and that SQL server, you can use.  "It is correct to all about values , but not several times."

  I suggest to round the value just before the display and user input must be two decimals.

  Then, you may need to do some things at the end of SQL server.  For example, when you update a value in the table, you may need to use logical server to explicitly truncate the value to two decimal places, as well as an update of "$ 34,56" explicitly updates the column "$34,5600.."  (This kind of thing should happen in the context of SQL Server).  You know that the user entry has exactly two significant digits, but maybe (maybe not...)! SQL server may not know this.  You want to ensure that the stored server internally represents exactly two digits, when the origin of a user input value.

  Do not err on the side of "convenience" or "which seems." good on the screen  (If you do, get ready get telephone communications of the accountants, always at inappropriate times of the night.)

• 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?
