• 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.)

• convert the varchar2 data type to the data number type

  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;

• create a view with the double data type

  I have Windows XP with 10g 10.2.0.1.0
  
  I need to create a view of the double and with the type of data, such as NUMBER (5.2), NUMBER or VARCHAR2 (20).
  such as:
  create see test (view_test varchar2 (20)) as (select view_test from double)
  
  
  Help, please. Thanks in advance.

  It seems a little strange, but you can do something like this with the CAST function:

  SQL> create view dual_view as
    2  select cast(null as number(5,2)) col1
    3        ,cast(null as date)    col2
    4        ,cast(null as varchar2(30)) col3
    5  from   dual;
  
  View created.
  
  SQL> desc dual_view

  Don't be stupid.

  If you do not want to use BLOBs then, or you can use the ordimage.

  It uses ordsys.ordsource for the storage of the image data type. This is a user defined Type of data in advance and has a property called LocalData that stores the actual image. And what is its data type? BLOB OBJECT.

• DLL for LabWindows/CVI 8.0 with the bool data type

  Hello

  I want to use a new SWIR camera in LabWindows/CVI 8.0 (Windows XP 32bits).

  The company delivered with the camera produced a 32-bit dll by using Microsoft Visual C++ 2010. The .dll and .lib and .h files include a working SDK/API (some functions with the bool data type)

  Compilation-online syntax error, variable Boolean is not a data type in LabWindows/CVI 8.0

  Generate the import of DLL-online syntax error library

  I tried to convert bool char (typedef unsigned char bool => no more syntax error but the functions does not work.)

  What can I do?

  Martin

  Hello again, Naumann!

  Microsoft Visual C++ 2010 represents Boolean using 1 byte, as stated by MSDN: https://msdn.microsoft.com/en-us/library/tf4dy80a(v=vs.100).aspx

  I guess that you import C++ functions using the syntax for extern "C". Otherwise, because of the C++ name mangling wouldn't you able to bind C++ library against your code CVI.

  You can also specify how you import C++ functions?

  In addition, because you have not described the problem as a corruption of heads or runtime error, I guess the C++ library function is called correctly the CVI. That said, I tend to believe that the problem is not really in the mechanism of interaction of C/C++, but in the C++ library. If you would start calling a dummy C++ function returning an integer from a simple CVI application that should work, because redefine bool in CVI 1 byte must ensure that settings are correctly transferred onto the stack.

  If you need to create a wrapper function of C++ that is not using bool and calls the C++ function, I expect to return the same result.

  Maybe you are missing a few prior initialization steps required? The provider of the camera also comes all example code?

  Best regards!

• Convert a varchar2 data type Date

  Hi guys,.
  
  Can someone help me convert a Varchar2 data type in the data type Date?
  
  I have a query and my column is a varchar2 data type.
  I want to just that convert the Varchar2 in a DATE, because I met
  problem in my query. I want to do the day1 day10 transaction.
  
  Ex:
  Day 1 = January 1, 2010
  Day10 = January 10, 2010
  
  table.record_date varchar2 (12)
  
  SELECT column1, Column2
  table
  where record_date between? and?
  
  How can I set the record_date between day1 and day10 since record_date is of type varchar?
  
  Thank you.
  
  Laetitia

  Lala,

  If the data in the database are in the format MM-DD-RR , then you must use the same format when you convert back to this day.

  So change the query to

  SELECT COLUMN1, COLUMN2 FROM TABLE WHERE TO_DATE(RECORD_DATE, 'MM-DD-RR') BETWEEN TO_DATE('01-JAN-2010') AND TO_DATE('10-JAN-2010')
  

  Kind regards

• For the complex data type, how to generate the Dll with compatible interface to C/C++

  Hello

  I used the Labview FPGA module to develop test equipment. Now, I need to write a driver that is to be a Dll with compatible interface to C/C++ for this equipment. So that my client who is familiar with C/C++ can call the driver without any study on labview. But I had a few problem on how to convert labview for C/C++ data complex data type. To clearly explain to my question, I have attached a simple example. (see attachment) I try to generate a Dll for the attached example VI and get the the function prototype at the head of the files as below:

  ' void OpenFpgaReference (LStrHandle * RIODevice, TD1 * errorIn, LVRefNum * FPGAVIReferenceOut, TD1 * errorOut).

  As you have known, the type of data "LStrHandle * RIODevice" and "LVRefNum * FPGAVIReferenceOut" Labview data format are. C/C++ do not have this kind of data type and can not reconige it. As a result, I can't call the Dll of C/C++ programming language. How to convert these two data type of labview for the C/C++ compatible data format, and then build the Dll? Anyone know about this?

  The answer is really apprecaited! Thank you in advanced.

  As I found in the following article:

  LVRefNum is the name of resource of LabVIEW VISA or refnum, and "it is impossible to convert LabVIEW VISA name of resource or refnum VISession valid ID."
  This means that external code modules can not access & control the session VISA which is open by labview. But for my purposes, I will not attempt to access this VISA extenal code(C/C++) session. I just hope that save this session VISA in the external code once I opened it in Labview dll; and pass it to the labview dll when needed. While I have not need to login again when I need to control the device. Is it possible to do?

  A LVRefNum is really just a single int32 value. Its meaning is useless for other environments than those who created it so that you Michael not any what in C/C++ caller but pass it back to other functions in your DLL, but this often isn't a problem at all.

  You can take the following statement of the LabVIEW extcode.h headers and add them to your delabviewed header files to make it work in such a way.

  #define Private (T) typedef struct T # _t {void * p ;} * T}

  Private (LVRefNum);

  The LStrHandle you must set a standard C string instead in your export DLL and document what is the size of the string buffer should have if it is an output parameter.

  TD1 error clusters should also be divided into their parameters (C compatible) separate for all items or just to the left of suite entirely.

  Please resolve.

  HIGH_VALUE datatype is LONG. You may not use for a long TIME in WHERE clause expressions. You need to loop through the partitions by selecting HIGH_VALUE and then comparing. Secondly, there is no need to select double to calculate expressions. For example:

  Select to_char (add_months (trunc (sysdate, 'MM'),-1), 'YYYYMM') | ' 00' in the double last_mnth_var;

  should be replaced by

  last_mnth_var: = to_char (add_months (trunc (sysdate, 'MM'),-1), 'YYYYMM') | ' 00'.

  and there is no need to add_months here:

  last_mnth_var: = to_char (trunc (sysdate, 'MM') - 1, "YYYYMM"). ' 00'.

  But the main question is simply ALTER TABLE MODIFY PARTITION COMPRESS allows compression but does not compress. You must issue ALTER TABLE MOVE PARTITION COMPRESS:

• 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.

  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.
