Java/Database SQL JDBC/CallableStatement

Execute stored procedure

  
 
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
public class Main {
  static String url = "jdbc:oracle:thin:@localhost:1521:javaDemo";
  static String username = "username";
  static String password = "welcome";
  public static void main(String[] args) throws Exception {
    Class.forName("oracle.jdbc.driver.OracleDriver");
    Connection conn = DriverManager.getConnection(url, username, password);
    CallableStatement stmt = conn.prepareCall("{call CREATE_USERS (?, ?, ?, ?, ?, ?)}");
    stmt.setString(1, "a");
    stmt.setString(2, "b");
    stmt.setString(3, "c");
    stmt.setString(4, "d");
    stmt.setString(5, "e");
    stmt.setString(6, "f");
    stmt.execute();
    conn.close();
  }
}

Use CallableStmts to call a stored procedure

 
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
public class CallableStmt {
  public static void main(String[] args) throws Exception {
    String driver = "oracle.jdbc.driver.OracleDriver";
    Class.forName(driver).newInstance();
    System.out.println("Connecting to database...");
    String jdbcUrl = "jdbc:oracle:thin:@localhost:1521:ORCL";
    Connection conn = DriverManager.getConnection(jdbcUrl, "yourName", "mypwd");
    CallableStatement cstmt = conn.prepareCall("{call getEmpName (?,?)}");
    cstmt.setInt(1, 111111111);
    cstmt.registerOutParameter(2, java.sql.Types.VARCHAR);
    cstmt.execute();
    String empName = cstmt.getString(2);
    System.out.println(empName);
    conn.close();
}
