Call Oracle Stored Procedure using JDBC CallableStatement

Calling stored procedure is same as calling stored function as mentioned in previous post. In this example we will perform INSERT, UPDATE, DELETE on Account table. Code snippets to show you how to call a Oracle stored procedure via JDBC CallableStatement, and how to pass IN parameters from Java to stored procedure.

1) Stored Procedure

A stored procedure in Oracle database. Later, calls it via JDBC.



create or replace procedure spAccount(p_acode number,p_aname varchar,
p_obalance number,p_descflag varchar)
IS
begin

--INSERTING METHOD
  IF p_descflag = 'I' THEN
    insert into account values (p_acode,p_aname,p_obalance);
  END IF;
  --UPDATING METHOD
  IF p_descflag = 'U' THEN
    update account aa set aa.acct_name = p_aname,
    aa.obalance = p_obalance
    where aa.acct_code = p_acode;
  END IF;
    --UPDATING METHOD
  IF p_descflag = 'D' THEN
     delete from account aa where aa.acct_code = p_acode;
  END IF;

  commit;
end spAccount;




2) Calls Stored Procedure via CallableStatement

The Account class contains:-
i)   Oracle JDBC Connection method
ii)  Insert, Update, Delete methods
iii) Setter and Getter methods
iv)  Perform Insert, Update, Delete method through stored procedure using CallableStatement  


import oracle.jdbc.pool.*;
import java.sql.*;

public class Account{

private OracleDataSource ODS;
private Connection CN;

private int Acode;
private String Aname;
private double Obalance;
private String descflag;

 public Account(){
 
 try{
 ODS = new OracleDataSource();
 ODS.setUser("adf");
 ODS.setPassword("adf");
 ODS.setURL("jdbc:oracle:thin://@127.0.0.1:1521:XE");
 CN = ODS.getConnection();
 }
 catch (Exception ex)
 {
  System.out.println("oops!"+ex.getMessage());
 }
}

 public void setAcode( int a1){
  Acode = a1;
 }

 public int getAcode(){
  return Acode;
 }

 public void setAname( String a1){
  Aname = a1;
 }

 public String getAname(){
  return Aname;
 }

 public void setObalance( double a1){
  Obalance = a1;
 }

 public double getObalance(){
  return Obalance;
 }

 public void setdescflag( String a1){
  descflag = a1;
 }

 public String getdescflag(){
  return descflag;
 }

 public void addAccount(){
 
 if (descflag == "I"){
 try{
 CallableStatement SQLPROC = 
                        CN.prepareCall("{ call spAccount(?,?,?,?)}");
 SQLPROC.setInt(1,Acode);
 SQLPROC.setString(2,Aname);
 SQLPROC.setDouble(3,Obalance);
 SQLPROC.setString(4,descflag);
 SQLPROC.executeUpdate();
 }
 catch (Exception ex){
 System.out.println("Oops! "+ ex.getMessage());
 }
 }
 }
 
 public void editAccount(){
 if (descflag == "U") {
 try{
 CallableStatement SQLPROC = 
                        CN.prepareCall("{ call spAccount(?,?,?,?)}");
 SQLPROC.setInt(1,Acode);
 SQLPROC.setString(2,Aname);
 SQLPROC.setDouble(3,Obalance);
 SQLPROC.setString(4,descflag);
 SQLPROC.executeUpdate();
 }
 catch (Exception ex){
 System.out.println("Oops! "+ ex.getMessage());
 }
 }
 }

 public void delAccount(){
 if (descflag == "D"){
 try{
 CallableStatement SQLPROC = 
                        CN.prepareCall("{ call spAccount(?,?,?,?)}");
 SQLPROC.setInt(1,Acode);
 SQLPROC.setString(2,Aname);
 SQLPROC.setDouble(3,Obalance);
 SQLPROC.setString(4,descflag);
 SQLPROC.executeUpdate();
 }
 catch (Exception ex){
 System.out.println("Oops! "+ ex.getMessage());
 }
 }
 }

}

3) Drive Class


public class driveclass{


 public static void main( String expsp[] ){ new driveclass();}

 driveclass(){
 Account act = new Account();
 act.setAcode(3);
 act.setAname("Multan Branch Account");
 act.setObalance(15000.12);
 act.setdescflag("I");

 act.addAccount();
 act.editAccount();
 act.delAccount();
 }
}

Done. When above JDBC example is executed, a new record will be inserted into database via stored procedure "spAccount". Change the Flag "U" to update and "D" to delete the records from the database.

How to Create Packages in Oracle Database using TOAD for Oracle

Image
What are Packages in Oracle Database A package is a group of procedures, functions, variables and SQL statements created as a single unit. It is used to store together related objects. A package has two parts, Package Specification and Package Body. Package Specification Package Specification acts as an interface to the package. Declaration of types, variables, constants, exceptions, cursors and subprograms is done in Package specifications. Package specification does not contain any code. Package Body Package body is used to provide implementation for the subprograms, queries for the cursors declared in the package specification.

How to create a Simple Scheduler Job in Oracle Database using Toad

Image
Scheduler is a process which runs programmed jobs at scheduled times. This process wakes up at the specified time and runs automatically. The basic elements of the scheduler are: Jobs Schedules Programs A job specifies what needs to be executed and when. A program is a collection of metadata that will be executed by the scheduler. It contains the name of the program (a procedure or an executable, the type of the program (pl/sql block, shell script etc). A schedule specifies when and how many times a job is executed. 1. Login to the database using Toad, and create a Scheduler Job as follows;
