Using Jdbc. Row. Set Objects The Java Tutorials.JDBCTM Database Access JDBC BasicsThe Java Tutorials have been written for JDK 8.Examples and practices described in this page dont take advantage of improvements introduced in later releases.A Jdbc. Row. Set object is an enhanced Result.Set object. It maintains a connection to its data source, just as a Result.Set object does. The big difference is that it has a set of properties and a listener notification mechanism that make it a Java.Beans component. One of the main uses of a Jdbc.Row. Set object is to make a Result.Set object scrollable and updatable when it does not otherwise have those capabilities.How To Use Update Query In Jdbc Driver' title='How To Use Update Query In Jdbc Driver' />This section covers the following topics You can create a Jdbc.Row. Set object in various ways By using the reference implementation constructor that takes a Result.Set object. By using the reference implementation constructor that takes a Connection object.By using the reference implementation default constructor.By using an instance of Row.Set. Factory, which is created from the class Row.Set. Provider. Note Alternatively, you can use the constructor from the Jdbc.Row. Set implementation of your JDBC driver.However, implementations of the Row.Set interface will differ from the reference implementation.VbWeb/9_10/Notes/10-databases_files/image002.jpg' alt='How To Use Update Query In Jdbc Driver' title='How To Use Update Query In Jdbc Driver' />These implementations will have different names and constructors.For example, the Oracle JDBC drivers implementation of the Jdbc.Row. Set interface is named oracle.Oracle. JDBCRow. Set.The simplest way to create a Jdbc.JDBC drivers are divided into four types or levels.The different types of jdbc drivers are Type 1 JDBCODBC Bridge driver Bridge Type 2 NativeAPIpartly Java.Eclipse and JDBC.Russell Bateman 2 March 2010 last update 21 November 2011.Row. Set object is to produce a Result.Set object and pass it to the Jdbc.Row. Set. Impl constructor.Doing this not only creates a Jdbc.Row. Set object but also populates it with the data in the Result.Set object. Note The Result.Set object that is passed to the Jdbc.Row. Set. Impl constructor must be scrollable.As an example, the following code fragment uses the Connection object con to create a Statement object, stmt, which then executes a query.The query produces the Result.Set object rs, which is passed to the constructor to create a new Jdbc.Row. Set object initialized with the data in rs.Statement. Result.Set. TYPESCROLLSENSITIVE.Result. Set. CONCURUPDATABLE.Queryselect from COFFEES.Rs new Jdbc. Row.Set. Implrs. A Jdbc.Row. Set object created with a Result.Set object serves as a wrapper for the Result.Set object. Because the Row.Set object rs is scrollable and updatable, jdbc.Rs is also scrollable and updatable.If you have run the method create.Statement without any arguments, rs would not be scrollable or updatable, and neither would jdbc.Rs. The first statement in the following code excerpt from Jdbc.Row. Set. Sample creates a Jdbc.Row. Set object that connects to the database with the Connection object con jdbc.Rs new Jdbc. Row.Set. Implcon. jdbc.Rs. set. Commandselect from COFFEES.Rs. execute. The object jdbc.Rs contains no data until you specify a SQL statement with the method set.Command, then run the method execute.The object jdbc. Rs is scrollable and updatable by default, Jdbc.Row. Set and all other Row.Set objects are scrollable and updatable unless otherwise specified.See Default Jdbc.Row. Set Objects for more information about Jdbc.Row. Set properties you can specify.Using the Default Constructor.The first statement in the following code excerpt creates an empty Jdbc.Row. Set object. public void create.Jdbc. Row. SetString username, String password.Rs new Jdbc. Row.Set. Impl. jdbc. Rs.Commandselect from COFFEES.Rs. set. Urljdbc my.Driver my. Attribute.Rs. set. Usernameusername.Rs. set. Passwordpassword.Rs. execute. The object jdbc.Rs contains no data until you specify a SQL statement with the method set.Command, specify how the Jdbc.Result. Set object connects the database, and then run the method execute.All of the reference implementation constructors assign the default values for the properties listed in the section Default Jdbc.Row. Set Objects.With Row. Set 1. 1, which is part of Java SE 7 and later, you can use an instance of Row.Set. Factory to create a Jdbc.Row. Set object. For example, the following code excerpt uses an instance of the Row.Set. Factory interface to create the Jdbc.Row. Set object, jdbc.Rs. public void create.Jdbc. Row. Set. With. Canon Mp530 All In One Printer Software . Row. Set. Factory.String username, String password.SQLException. Row.Set. Factory my. Row.Set. Factory null.Jdbc. Row. Set jdbc.Rs null. Result.

Factory implementation, com.Row. Set. Factory.Impl. my. Row. Set.Factory Row. Set.Provider. new. Factory.Alternatively, if your JDBC driver has its own Row.Set. Factory implementation, you may specify it as an argument of the new.Factory method. The following statements create the Jdbc.Row. Set object jdbc.Rs and configure its database connection properties.Rs my. Row. Set. Factory.Jdbc. Row. Set. jdbc.Rs. set. Urljdbc my.Driver my. Attribute.Rs. set. Usernameusername.Rs. set.

Set object will have the following properties type Result.Set. TYPESCROLLINSENSITIVE has a scrollable cursorconcurrency Result.Set. CONCURUPDATABLE can be updatedescape.Processing true the driver will do escape processing when escape processing is enabled, the driver will scan for any escape syntax and translate it into code that the particular database understandsmax.Rows 0 no limit on the number of rowsmax.Field. Size 0 no limit on the number of bytes for a column value applies only to columns that store BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR valuesquery.Timeout 0 has no time limit for how long it takes to execute a queryshow.Deleted false deleted rows are not visibletransaction.Isolation Connection.TRANSACTIONREADCOMMITTED reads only data that has been committedtype.Map null the type map associated with a Connection object used by this Row.Set object is nullThe main thing you must remember from this list is that a Jdbc.Row. Set and all other Row.Set objects are scrollable and updatable unless you set different values for those properties.The section Default Jdbc.Row. Set Objects lists the properties that are set by default when a new Jdbc.Row. Set object is created.If you use the default constructor, you must set some additional properties before you can populate your new Jdbc.Row. Set object with data.In order to get its data, a Jdbc.Row. Set object first needs to connect to a database.The following four properties hold information used in obtaining a connection to a database.JDBC URL for the database to which the user wants to connectdatasource.Name the name used to retrieve a Data.Source object that has been registered with a JNDI naming service.Which of these properties you set depends on how you are going to make a connection.The preferred way is to use a Data.Source object, but it may not be practical for you to register a Data.Source object with a JNDI naming service, which is generally done by a system administrator.Therefore, the code examples all use the Driver.Manager mechanism to obtain a connection, for which you use the url property and not the datasource.Name property. Another property that you must set is the command property.This property is the query that determines what data the Jdbc.Row. Set object will hold.For example, the following line of code sets the command property with a query that produces a Result.Set object containing all the data in the table COFFEES.Rs. set. Commandselect from COFFEES.After you have set the command property and the properties necessary for making a connection, you are ready to populate the jdbc.Rs object with data by calling the execute method.My.
