Can we use SQL for java language?
No. SQL stands for Structured Query Language and that in itself is a language and it is totally different from Java. However, you can use SQL queries inside Java code with the help of JDBC (Java DataBase Connectivity). But the Java compiler cannot understand/compile standalone SQL syntax unless it is used as part of JDBC.
How can you connet java with sql in java programming?
JDBC mean Java Database Connectivity. In java, using JDBC drivers, we can connect to database. Steps to connect to JDBC. 1) Load the driver, using Class.forName(DriverName); 2) Get the connection object, Connection con = Driver.getConnection(loaded driver name); 3) Create a SQL statement, Statement s = con.createStatement(); 4) Create Resultset object using the statement created above, ResultSet rs = s.executeQuery("sql statement"); Iterate the result set to get all the values from the database. Finally don't miss this 5) s.close(); 6) con.close() ;
What is marshalling and Demarshalling?
data marshalling in java means that the structured data item is flattening and converted into external representation data demarshalling is the process of convert the data back to the internal representation and rebuild the data structures.
How do you add a variable from a Java program into a database through an SQL command within the Java program?

Is learning SQL easy for a Java student?
SQL is quite unrelated to Java. It isn't exactly a programming language in the traditional sense; but rather a series of commands to get information from (and to) a database. The basics are actually quite simple; certainly simpler than learning Java.
Difference between Object-based Data Model and Record-based Data Model?
Object-based data model represents data as objects with attributes and methods, providing a way to model real-world entities in a programming language like Java. On the other hand, record-based data model organizes data into fixed-format records or tuples, typically used in databases like SQL to store and retrieve structured information. Object-based data model offers a more dynamic and flexible way to represent data compared to the rigid structure of record-based models.
What is deserialization in java?
De-serialization is the opposite process of serialization. This is the process where we convert data that has already been written out onto a stream as part of serialization into Java objects.

Sql is applicable to?

What is the difference between SQL and SQLPlus?
Structured Query Language, abbreviated as SQL, is a programming language. It is designed to manage data stored in relational databases. Various commands or operations like Select, Group by, Insert, Modify, etc, are implemented using SQL to fetch, retrieve or add data to the database. It can be used in correlation with other programming languages like Python or Java, to build applications. Any tool or application can communicate with the Oracle server using the command language SQL. Oracle SQL has numerous extensions. A SQL statement that you enter is saved in memory's "SQL buffer" and stays there until you write another SQL statement. An Oracle tool called SQLPlus identifies and sends SQL statements to the Oracle9i Server for execution. It has a built-in command language. It is a client program allowing users to enter SQL and PL/SQL commands and execute them. SQLPlus comes with the Oracle installation. It is commonly used to develop and run SQL and PL/SQL statements, scripts, and reports. SQL SQLPLus is a language used to access data from the Oracle server by talking with it. Recognizes SQL statements and sends them to the server Is based on American National Standards Institute (ANSI)-standard SQL Is Oracle's interface for running SQL statements proprietary? manipulates the database's data and table definitions. does not permit changing of database values employs a termination character to carry out directives right away. does not need termination characters and immediately carries out commands. Uses functions to perform some formatting Uses commands to format data
