Java: Error while saving date value to database(Simpledataformat)

Question

I am trying to save a date in DB but i am getting the below error. I am confused because i am sending the same format but still throwing exception:

java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss[.fffffffff]

If i am trying in SQL Developer in the below way it works fine

to_date('01/01/1900', 'mm/dd/yyyy')

Through java i tried doing as below

First Method

SimpleDateFormat format1 = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
Date myDate = format1.parse("01/01/1900 00:00:00");

Second Method

SimpleDateFormat format1 = new SimpleDateFormat("dd/MM/yyyy");
Date myDate = format1.parse("01/01/1900");

Where am i going wrong.

PS : Please before marking it as duplicate and stopping people from answering question understand i have tried something and got the error.

Answer 1

tl;dr

myPreparedStatement.setObject(
    … , 
    LocalDate.parse( 
        "01/01/1900" , 
        DateTimeFormatter.ofPattern( "dd/MM/uuuu" )
    )
)

The Answer by Just another Java programmer is correct.

Furthermore, you should not use strings to communicate date-time values with a database. Use date-time classes.

The modern way is with java.time classes, supplanting the troublesome legacy date-time classes.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec .

ZoneId z = ZoneId.of( "America/Montreal" );
LocalDate today = LocalDate.now( z );

You can parse directly from a string in standard ISO 8601 format.

LocalDate localDate = LocalDate.parse( "2016-01-23" );

Or specify each part.

LocalDate localDate = LocalDate.of( 2016, Month.JANUARY , 23 );

To parse other formats, use DateTimeFormatter class. Search Stack Overflow for many examples.

Database

If your JDBC driver complies with JDBC 4.2 or later, it should be able to pass a java.time type with PreparedStatement::setObject and fetch with ResultSet::getObject .

myPreparedStatement.setObject( … , localDate );

…or…

myPreparedStatement.setObject( … , localDate , JDBCType.DATE );

If your driver is not so enabled, fall back to using java.sql.Date . This awkward class pretends to represent a date-only value (but actually has a time component set to midnight which we are supposed to ignore). To convert to/from java.time look to new methods added to the old classes.

java.sql.Date sqlDate = java.sql.Date.valueOf( localDate );

And going the other direction.

LocalDate localDate = sqlDate.toLocalDate();

Pass to PreparedStatement::setDate .

myPreparedStatement.setDate( … , sqlDate );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date , Calendar , & SimpleDateFormat .

The Joda-Time project, now in maintenance mode , advises migration to java.time.

To learn more, see the Oracle Tutorial . And search Stack Overflow for many examples and explanations. Specification is JSR 310 .

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport .
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use… .

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval , YearWeek , YearQuarter , and more .

Answer 2

Your date pattern does not match.

Better is to use a PreparedStatement so you never will rely on string conversion.
