can you make your question little more elaborate? subject and content differs. given below high-level information on QVD.

QVD means Qlikview data file. Storing raw source data for later used in the Data model. When reading data from the QVD is faster in compare to other sources.

One way of generating QVD file is by storing the table data as shown below.

STORE TableName INTO FileName.qvd (QVD);

QVD's can be generated by giving STORE command as mentioned above or also by giving using Include variable.

You simple create a variable and use that variable in script to store the file.

Ex:

LET vInclude_Directory = '..\Includes\Variables.txt';

Variables.txt file can store your SET or LET functions and also the destination for storing QVD

After your table loads you use following statement

STORE FILENAME INTO $(vQVD_E_Directory)\FILENAME.QVD (qvd);

Include file can also be used for storing your DB connection.

You can use either of these

STORE FILENAME INTO your destination filder\FILENAME.QVD (qvd); <<< this one might look easy

Include file to store this destination for future use as well. <<< But this one is good too.

FYI.

QVD stores the RAW data and is encrypted file. The raw data is stored and saved into QVD for future use so that you don't have to connect to db each time you wanna load that particular file.

To use use a Data Model you need to load all the QVD's (Tables) in a qvw and then use that QVW as binary load to source qvw file.

QVD alone cannot store a Data Model, it can store one Table not all tables in single QVD. Unless you join or concatenate all tables into one, which will not make a much of Data Model.

Hi Vijay,

There is no concept of raw QVD or Model QVD in QlikView.

We have only one QlikView Data File (QVD), either it is created by Extraction Layer, Transformation Layer, Visualization Layer or created by QlikView Management Console.

We have two mode to read QVD file into QlikView, description and examples are given below,

1. Optimized mode (fastest mode): Loading data straight forward, there is no transformation or any field renaming.

productSales:

LOAD * Inline [

Product, Sales

A, 100

B, 20

C, 30

];

2. Standard mode (fast mode): Loading data with performing transformation over the fields or renaming fields.

productSales:

LOAD Product as myProductField, Sales as myProductSales Inline [

Product, Sales

A, 100

B, 20

C, 30

];

Here are the ways to Create QVD file in QlikView,

1. QVD creation by QVW

productSales:

LOAD * Inline [

Product, Sales

A, 100

B, 20

C, 30

];

STORE Product from productSales into C:\Datastore\QVD\productSales.qvd (qvd);

STORE productSales into C:\Datastore\QVD\productSales.qvd (qvd);

STORE * from productSales into C:\Datastore\QVD\productSales.qvd (qvd);

2. QVD creation by QlikView Management Console (QMC)

Inserting the QVD generation script as a task in System > Supporting Tasks > QVD Generation

Enter information in the Basics and Parameters fields, and click on Apply

Please check,

QVD

Hi Vijay ,

By using STORE command we can create QVD file.

Please use the following syntax ,

STORE table_name INTO file_name.qvd(qvd);
