如何使用Java在Oracle中插入自定义日期时间？

Question

Hi i have a column (type date).I want to insert custom date and time without using Preparedstatement .i have used

String date = sf.format(Calendar.getInstance().getTime());
String query = "Insert into entryTbl(name, joinedDate, ..etc)  values ("abc", to_date(date, 'yyyy/mm/dd HH:mm:ss'))";
statement.executeUpdate(query);

but am getting literal doesnot match error. so even tried with "SYSDATE" .Its inserting only date not time.So how to insert the datetime using java into oracle?please any one help..

Answer 1

It is strongly recommended to use PreparedStatement to counter potential SQL injection attacks, instead of building raw SQL queries to interact with the database.

That said, you can specify the value for date column as a string in yyyy-MM-dd HH:mm:ss format as well:

SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String date = sf.format(Calendar.getInstance().getTime());
String query = "INSERT INTO entryTbl(name, joinedDate, ..etc.,)  values ('abc', '" 
    + date + "', ...etc.,)";
statement.executeUpdate(query);

Answer 2

I think yyyy/mm/dd HH:mm:ss should be updated as : YYYY/MM/DD HH:MI:SS TZH:TZM and use to_timestamp -- documentation here

 String query = "INSERT INTO entryTbl(name, joinedDate, ..etc.,) "+
           "values ('abc', "+
           "TO_TIMESTAMP('"+dateString+"', 'YYYY/MM/DD HH:MI:SS TZH:TZM'), etc.,)";
