How to create a table in Oracle using JDBC?
You can create a table in a database using the CREATE TABLE query.
Syntax
CREATE TABLE table_name( column1 datatype, column2 datatype, column3 datatype, ..... columnN datatype, PRIMARY KEY( one or more columns ) );
To create a table in a database using JDBC API you need to −
Register the Driver: Register the driver class using the registerDriver() method of the DriverManager class. Pass the driver class name to it, as parameter.
Establish a connection: Connect ot the database using the getConnection() method of the DriverManager class. Passing URL (String), username (String), password (String) as parameters to it.
Create Statement: Create a Statement object using the createStatement() method of the Connection interface.
Execute the Query: Execute the query using the execute() method of the Statement interface.
Following JDBC program establishes connection with Oracle database and creates a table named DISPATCHES −
Example
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class CreateTable_Oracle {
public static void main(String args[]) throws SQLException {
//Registering the Driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
//Getting the connection
String oracleUrl = "jdbc:oracle:thin:@localhost:1521/xe";
Connection con = DriverManager.getConnection(oracleUrl, "system", "password");
System.out.println("Connection established......");
//Creating the Statement
Statement stmt = con.createStatement();
//Query to create a table
String query = "CREATE TABLE DISPATCHES("
+ "ProductName VARCHAR (20) NOT NULL, "
+ "CustomerName VARCHAR (20) NOT NULL, "
+ "DispatchDate date, "
+ "DeliveryTime timestamp, "
+ "Price INT, "
+ "Location varchar(20))";
stmt.execute(query);
System.out.println("Table Created......");
}
}Output
Connection established...... Table Created......
In oracle you can get the list of tables using the query/command −
Select * from tab;
If you verify the list of tables in the database using this, you can observe the newly created table in it as −
