So far, I have not found a clear answer to this.
I’d like to know what the equivalent is for a SQL type DATETIME and the java type, using a PreparedStatement.
But it states that SQL type “DATETIME” is the same as sql.date, but when looking at the SQL date docs (http://download.oracle.com/javase/7/docs/api/java/sql/Date.html), it says the time is truncated (all zeros).
What I want is to be able to specify a
preparedStatement.setDateTime() or some sort.
The only other way I see is using a timestamp, but that would require me to change the column type, while I cannot imagine someone else never had this problem before?
Edit: I am using MYSQL.
The java.sql package has three date/time types:
java.sql.Date– A date only (no time part)
java.sql.Time– A time only (no date part)
java.sql.Timestamp– Both date and time
You want the last one:
If you are using these types, you don’t need to call a specific setter; just use:
java.util.Date date = new Date(); Object param = new java.sql.Timestamp(date.getTime()); // The JDBC driver knows what to do with a java.sql type: preparedStatement.setObject(param);
The equivalent of MS SQL Server or MySQL DATETIME data type or Oracle DATE data type is java.sql.Timestamp.
I had a similar problem with my Mysql having SQL date and locally in my app i only had Date
I solved like this
java.sql.Date dataStartSql = new java.sql.Date(start.getTime());
After that used the setDate normally, and I used a getTimestamp to retrive the first value.
where start is a Date object.
In Java we have java.util.Date to handle both Date and Time values.
In SQL, you have commonly Dates (only dates), Time (only time) and DateTime/Timestamp (date and time).
In your Java program, usually you’ll always have java.util.Date, so each time you’re setting Dates/Times/DateTimes in PreparedStatements, always choose exactly which one you need, according to the database.
