New users of QlikView will often create a new QlikView file (utility or QVW (QlikView Worksheet)) by way of navigating to file | New from the QlikView toolbar. This command opens the choose information supply wizard, wherein the user might also browse to a domestically saved Excel document and follow the wizard steps to extract that statistics into the brand new QVW. The simple steps for connecting QlikView to a database are: Driving force set up of a supported database, configuring ODBC (if the use of an ODBC driver), and connecting it via the QlikView Script Editor dialog. Installing Drivers As with every facts extraction device, it's far important to have item Linking and Embedding Database (OLE DB) or Open Database Connectivity (ODBC) hooked up on the computer or server so one can get right of entry to a database. The type of connection is determined by using the database to that you are connecting. Microsoft windows comes pre-mounted with several OLE DB/ ODBC drivers. For different database connections, you need to go to an appropriate database supplier site’s down load segment to get the state-of-the-art ODBC connection driving force for that database. OLE DB drivers are maximum typically used to hook up with Microsoft access databases, and this motive force is generally established with the Microsoft windows operating device. Many OLE DB connectors also are available for other Relational Database control systems (RDBMS) consisting of PostgreSQL, DB2 and Firebird, among others. OLE DB is mentioned to be superior to an ODBC connection for QlikView programs (speed, connectivity, performance), so take into account using OLE DB if possible. An smooth manner to check whether or not the pc already has the OLE DB connector hooked up is from within QlikView. In QlikView, navigate to record | Edit Script. in the Script Editor conversation’s statistics tab, pick OLE DB in the drop-down list and click connect. The records link properties dialog should appear if an OLE DB driving force is set up. If a driver isn't always set up, you'll acquire an mistakes message indicating that the OLE DB driver is not established and a connection can not be made to the database. In realistic use, maximum databases (except Microsoft access) connect thru the maximum widely used ODBC connection drivers to be had. though each 32-bit and sixty four-bit ODBC drivers can be used with QlikView, when putting in a brand new ODBC connection driver, select the right type to paintings along with your model of QlikView. if you are the usage of the 32-bit QlikView application, deploy the 32-bit driving force handiest. in case you are the usage of the 64-bit model of QlikView, you can use both the 32-bit or 64-bit ODBC driver. If the database you are connecting to is a 64-bit database (and you're connecting from a 64-bit QlikView model), make sure to use the 64-bit ODBC driving force so that you can gain pace and performance from the sixty four-bit connection. Test if your laptop or server already has the favored driver mounted by way of navigating to the windows control Panel (start | Settings | manipulate Panel). in the control Panel, open the executive tools panel, then discover the records resources ( ODBC) icon, and locate the ODBC motive force in the machine DSN tab. click on upload in the ODBC facts supply management conversation field. In case you can not discover the facts sources icon, look for ODBC on top of things Panel to display the executive gear window. If you could’t find the administrative gear window, it is probably that no OLE DB/ODBC drivers are hooked up yet, and you have to go to the RDBMS dealer down load website so that it will deploy the essential driving force. If you have installed the right vendor ODBC driving force on the pc or server with the intention to be running QlikView queries, continue the setup by means of configuring the ODBC DSN statistics. Configuring ODBC connection relying on what type of driver you are the use of (32 bit or 64 bit), navigate and open the correct administrative setup tool to configure your ODBC connection: The 32-bit model of the Odbcad32. exe file is positioned at %systemdrive% windows System32 The 64-bit version of the Odbcad64. exe record is placed at %systemdrive% home windows SysWoW64 The ODBC data source Administrator dialog displays and allows you to pick the database to apply with QlikView. to add a brand new connection, navigate to the system DSN tab inside the ODBC information supply Administrator conversation, pick out add, then choose the ODBC driving force for the database to that you are connecting (take into account, in case your RDBMS isn't always indexed, you have to install a driver for it). After selecting the favored ODBC motive force, click on finish. A conversation for the selected database driver is displayed that permits you to enter the call of your information source and other connection parameters. click on on the ok button when you finish getting into the relationship records, and the brand new database connection name is displayed in the device DSN tab. Connecting to the database from QlikView QlikView can connect with maximum of the popular databases like MySql, square Server, Oracle, Postgress etc. it is able to fetch statistics and desk structures into QlikView environment and save the results in its reminiscence for similarly analysis. the steps to connect with any of those databases involve creating an ODBC connection using a DSN after which the usage of this DSN to fetch the statistics. as soon as the DSN information has been created, continue putting in the connection in QlikView, the use of the QlikView Script Editor. Open a QlikView record and access the Script Editor (via navigating to document | Edit Script, or with the aid of retaining Ctrl + E). inside the Script Editor conversation’s facts tab, select ODBC from the drop-down listing and click on on join (if the driving force hooked up 64 bit, deselect the pressure 32 bit checkbox). select the database name within the hook up with information supply dialog and click on good enough. input a password for the records source if triggered. once related, word that QlikView inserts a join statement within the script, together with ODBC connect to [DATABASE NAME; DBQ =DBNAME];. From this factor, the database is attached to QlikView and you may now create choose statements to start constructing your script. if you are not linked to the database while moving ahead, you'll be triggered for the facts supply again. inside the Script Editor window, press enter a few times to enhance to the next line after the connect assertion, and click on at the pick button to choose the database tables. be aware that even as you may connect to multiple databases in a QlikView report, simplest one database is connected at a time. each successive connect declaration disconnects the previous connection. you could additionally use the Disconnect command to explicitly terminate the maximum contemporary database connection. inside the next bankruptcy, we can hold building the QlikView script. Supported Databases QlikView helps the most commonplace databases, and any database that makes use of ODBC or OLE DB connections, inclusive of the most common database structures: Oracle, MS get admission to, MS sq. Server, Teradata, PostgreSQL, MySQL, DB2, Sybase, Netezza, and Informix. Connectors also are available thru the QlikView Expressor device, which adds ETL functionality. QlikTech additionally offers connectors to a number of software as a provider (SaaS) programs, along with J.D.Edwards, SAP, and sales pressure (extra Licensing prices apply). A connector to Informatica (ETL) is likewise available for buy. 1/3-party connectors to LinkedIn, facebook, Twitter, and others also are available for purchase. This concludes the object on a few factors concerning how to connect to ODBC/ OLE DB facts assets using QlikView.
