#Ibm db2 data studio tutorial drivers#
You may not be able to play the video format WebM as it needs additional drivers to play the videos. There is a mute/sound on button under the video. The video will not play until the you click on it. The given top answer was for the time (6 years ago) the best solution as requestAnimationFrame was not widely supported (if at all) but requestAnimationFrame is now standard across the Major browsers and should be used instead of setTimeout to reduce or remove dropped frames, and to prevent shearing. There is currently no reliable method that can determine a videos frame rate unless you know the video frame rate in advance you should display it at the maximum display refresh rate possible on browsers. Using setTimeout will also introduce video shearing created because setTimeout can not be synced to the display hardware.
It uses the setTimeout and a rate of 33.333.ms which setTimeout will round down to 33ms this will cause the frames to be dropped every two seconds and may drop many more if the video frame rate is any higher than 30. The previous answers by user372551 is out of date (December 2010) and has a flaw in the rendering technique used. A mute function (under the video click mute/sound on to toggle sound) and some error checking to catch IE9+ and Edge if they don't have the correct drivers. The demo below has some minor differences to the example. The minor differences are to do with onload events and the fact that you need to render the video every frame or you will only see one frame not the animated frames.
However, the XmlDocument data needs to be first added using () method after it is converted to String using InnerXml method.Displaying a video is much the same as displaying an image. The CID value can be concatenated to theCommandText string. Once XmlDcoument object containing customer info data has been created by CreateCustXML() method, we can now insert the data into the table. The Example shows insert of new customer CID and INFO into the CUSTOMER table. The creation of INFO XML data is done by a separate CreateCustXML() method as shown below In this case, Sample CUSTOMER table was not created with identity column. An identity column that is defined as generated by default gives an application a way to explicitly provide a value for the identity column. You should utilize identity column, which provides a method for DB2 database to automatically generate a unique numeric value for each row in a table.Īn identity column that is defined as generated always prevents the overriding of values in an SQL statement. Since CID is the primary key and thus needs to be unique, we issue a simple query against the CUSTOMER table’s CID column to obtain the current MAX value, then add one to generate the new CID.įor the primary key CID generation, we used MAX()+1 but this is not ideal way to generate the key. The HISTORY column information is not required. Inserting new Customer Information requires creation of data for CID (customer ID) and INFO (customer information).

NET data provider public static DB2Connection ConnectDb(String alias, String userid, String password ) NET Data Provider using System.Xml Ĭonnecting to the DB2 database using.
NET Data Provider using System using System.Data using 2 //needed for IBM DB2. The namespaces shown in below are required for given samples: If passed database alias is null, it will establish default connection to the SAMPLE database.Ĭonnection is established by first creating DB2Connection object and passing the connection string to the constructor: DB2Connection conn = new DB2Connection(connectString) The ConnectDb() method will return DB2Connection Object once connection has been established using the three parameters (db alias, userid, and password) required for the connection string. NET data provider is implemented in ConnectDb() method. The connection code to IBM DB2 database using DB2. In the following set of samples, each task has been presented as a separate method.Įstablishing the connection to the databaseĮstablishing connection to the database is the essential first step. The primary key consists of CID (customer ID) column. The CUSTOMER table in the SAMPLE database has three columns= as defined in Table. In this section, we provide sample C# application codes, which utilize IBM DB2.NET Data provider to demonstrate inserting new customer data into the Connection Object customer table as well as updating and deleting existing customer information in the SAMPLE database.
