Inserting date from java to Oracle DB

Question

I was trying to insert a value into one of the columns with DATE datatype in Oracle DB through java.

Tried with the below

insertSurveyQuery.append("cast(to_date('12/31/8888', 'MM/dd/yyyy' )as date), ");

OP in Oracle DB:

DEC-31-88

but i want the date to be stored like 12/31/8888.

Any of your help is appreciated!

-Thanks!

Answer 1

This is how your SQL client display dates. You can alter this format by using:

alter session set NLS_DATE_FORMAT='MM/dd/yyyy';

Internally (in DB) DATE is stored numerically so it doesn't have any format.

Answer 2

If you have many users accessing your application, then you could do the following in Java code

Date newDate = new SimpleDateFormat("mm/dd/yyyy").parse(myDate);

and use newDate in insert or update statement.

By doing this you do not need to change client settings.

Answer 3

First you have to create table in the format of

create table t1
(
ename varchar(20),
address varchar(20),
hire_date date,
salary number(5),
dob (we enter as 'dd-mm-yyyy')
);

In which you will have to give the date column as dd-mm-yyyy type then you can set data as you want.

Answer 4

Oracle doesn't support the format of DD/MM/YYYY. If you want to store the date time or time stamp you have to use DD-MM-YYYY format.

In direct insert query:

  SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy' 'hh:mm:ss a");  
     String date = "01-01-1900 01:00:00 AM";

In Procedure :

create or replace 
PROCEDURE insertDATE(
        DATE_PARAM IN VARCHAR2,
         )
IS
 BEGIN 

 INSERT INTO CUSTOMER("DATE")
  VALUES (TO_TIMESTAMP(DATE_PARAM,'DD-MM-YYYY HH:MI:SS AM'));
  COMMIT;
  END;
