• How to use a collection type of variable binding to execute dynamic statement

  Hello
  
  We have a case where we copy selective data from A to B schema of schema in an oracle database. The copy is obtained using
  run immediately 'insert'. target_schema |'. TableA select * from '. from_schema |'. where a.id table (select test_id of ' | from_schema |'.) Table c); " ;
  
  It works very well it takes an average of 10 seconds to copy around 14 paintings. We have an obligation to bring this time to 2 seconds. An observation was the clause
  "Select test_id of ' | '. from_schema |'. Table c"in the statement sql preceding repeats for many inserts. So, we thought bulk get this set of codes of practice and use a vatiable bind to collection for the immediate run clause type. Any suggestions on how to achieve this?
  
  Thank you

• How to get information about the types within a user defined package

  Hi all

  the req's, want to build a script dynamically using data dictionary
  so if possible, I take the name of the type within the package specification.

  Let me rephrase - is there a data dictionary to get information on the type defined by the user within a package specification

  Best approach will be to have a standard in the definition of data types.

  Have a process to follow the object definitions in the package if it is mandatory.

• Data Modeler: how to create and use the collection type

  Hello
  essentially of departure I don't understand how (for example) create and use the data based on the type of data varray type.
  
  Please notify.
  Thank you
  Andrew

  Hi André,.

  You can create new types of collection (varray/table) in two ways:
  (1) in the browser - find 'Types of data' > 'Types of Collection' node menu dropdown - there just 'create new collection type' it
  (2) in the types of data model diagram - you can create collection "some type structured" or collection of references to the it - use 'new Collection... '. "tool and click first on sight structured type and after the structured type that will contain the collection - new attribute is added to the latter and if there is none this type of collection already didn't set the new collection type are created and you can change it later.

• Question about the Type of SQL equivalent Collection Oracle

  (1) I read documentation collections oracle, can I know why the 'STORE AS' clause is used only when creating the table, but not when the object creation?

  Table:

  CREATE TYPE CourseList AS TABLE OF VARCHAR2(64);
  CREATE TABLE department (
    name     VARCHAR2(20),
    director VARCHAR2(20),
    office   VARCHAR2(20),
    courses  CourseList)
    NESTED TABLE courses STORE AS courses_tab;
  

  Object:

  CREATE TYPE CourseList AS TABLE OF VARCHAR2(10)  -- define type
  CREATE TYPE Student AS OBJECT ( -- create object
     id_num  INTEGER(4),
     name    VARCHAR2(25),
     address VARCHAR2(35),
     status CHAR(2),
     courses CourseList)  -- declare nested table as attribute
  

  (2) also can I know what is the difference between OBJECT & RECORD?

  My understanding is that the OBJECT is entity sql where you create and store data in this document, while the RECORDING is PLSQL entity where you group different types of data elements in one?, hope you can give me an example to better understand.

  Thank you.

  Fix. The column of the course are (similar to an array) collection type. This requires a "nested table" for this column store the list of the values in this column.

  This approach however is an exception to the rule - as it flies in the face of robust and sound design mathematically, relational.

  (2) also can I know what is the difference between OBJECT & RECORD?

  A record is similar to a struct in C/C++. A record contains one or more fields/variables. It's a basic structure for the creation of a 'container of variables' and by the way this container between code units, as oppose to pass individual variables. It is also the basis for the creation of intelligent data structures in structured programming. For example an IP socket structure is a unique smart container consisting of items/variables such as socket, protocol family and type, flags address and so on.

  It is a standard feature in most (if not all) of the structured programming languages - C / C++ and Pascal, Cobol and Visual Basic. PL/SQL is based on the Ada language - and like other members of language (including Pascal), PL/SQL uses the word registration reserve to set a record structure.

  Objects are created in Oracle using the "create or replace type... as object'clause. The correct term is an object oriented class. This differs from a record as a class has data and code. Unlike a record that counts only data.

  Given in a class are called properties. The code of a class is called methods. There are different types of member methods and methods such as the static class constructors, destructive methods.

  Oracle class object is defined using SQL. (Methods) code of this class is set using PL/SQL.

  The classes also supports features like inheritance. Allowing a child class extend the implementation of the parent class. This is not supported by a record structure, beyond a structure that contains another structure as a field attribute. Classes supports the substitution in a child class, the methods of the parent class. As records are composed only of data and not code, there is nothing like ito feature for structures Records.

  Yes, it's a typo. I also tried with "STOP_STAT_RES", but the result is the same.

  What are you talking about? Without doubt, one of the two generates a compile exception because the data type is incorrect...

  Monica wrote:
  STOP_STAT_RES is a collection of number abd the data types Date.

  Do you mean that you have created a user-defined type (e.g. CREATE TYPE >) which has attributes NUMBER and DATE? And that STOP_STAT_RES is a collection of such user-defined? Can you post the this user-defined type declaration?

• How to access objects collection

  How to access the collections of objects for example ReportSections report? I can access ReportSection, but not his collection...

  Reference: http://www.ni.com/pdf/manuals/372844e.pdf

  Maybe you don't understand exactly what section of the report is. According to the help:

  Use this class objects to store, update and transfer reports. You typically use the ReportSection objects to avoid creating copies of a report that the report is transferred between the generator of reports, process, Report and ReportView control object models. You can create a new ReportSection object by calling the Report.NewReportSection method. ReportSection objects can contain other ReportSection objects.

  As a general rule, a process template creates and updates the ReportSection object and assigns to the report object by setting the Report.ReportSection property.

  It has a sub-property called ReportSubsections , which specifies a reference to the ReportSections object, which is a collection that contains a list of child ReportSection objects to the current object. Looking at this object, it's a list of items that you can index through to get each.

  How do you manage file types in windows 7? There was a tab for it under XP folder options. If I can't solve the problem I will downgrade to xp and back to windows 7.

  Tab file types has been removed in Windows Vista & Windows 7 and replaced by "default programs". If you need to customize the type of file to a higher level associations (for example, the addition or the change of a supplementary verb in a class file), you need to maybe use a third-party tool or change the registry manually.

• How can I change the type of image file to download on a site like walmart or walgreens for printing?

  How can I change the type of image file to download on a site like walmart or walgreens for printing?

  In general, they will accept the image in the format, that it was taken (if it was taken by the majority of cameras or cell phones).  But if so, you have a few options.

  The most simple and integrated solution is Microsoft Paint.  Yes it is from the 1980s, but it still works and changes of a good job for a time.  Just to right click on the photo file, choose open with and choose paint.  Then go to file > save as and save this return as the file type you want it to be (like PNG or BMP or JPG, quality declining in the JPG option).

  If you need more options like changing the quality he uses during conversion, another free option (of the very very many) is Paint.NET, an open source free image editing program. http://www.dotPDN.com/downloads/PDN.html

  There are also programs that can do it in bulk, so you can highlight 300 photos and do convert them all at once.  You can do this for free or with tools like Photoshop.
