I have a database table TableA, which has a column 'theDate' for which the datatype in the database is DATE.
When I save a java.util.Date to 'theDate' through GORM it appears to save just the date value when I look at the data in the table by just executing select * from TableA.
However, when I run a query such as:
select * from TableA where theDate = :myDate
No results are found, but if I run something like;
select * from TableA where theDate <= :myDate
I do get results.
So it's like the Time is relevant.
My question is how do I save a Date and query for a Date ignoring the Time completely and just matching on an exact Date only?
Thanks.
note: I have also tried using sql.Date and util.Calendar but to no success.
clearTime()
You can use clearTime() before saving and before comparing to zero out the time fields:
// zero the time when saving
new MyDomain(theDate: new Date().clearTime()).save()
// zero the target time before comparing
def now = new Date().clearTime()
MyDomain.findAll('SELECT * FROM MyDomain WHERE theDate = :myDate', [myDate: now])
joda-time plugin
An alternative would be to install the joda-time plugin and use the LocalDate type (which only holds date information, no times) instead of Date. For what it's worth, I don't think I've worked on a project with dates without using the Joda plugin. It's completely worth it.
If you have date saved without clearing you could retrieve it using range, as Jordan H. wrote but in more simple way.
def getResults(Date date) {
def from = date.clearTime()
def to = from + 1
def results = MyDomain.findAll("from MyDomain where dateCreated between :start and :stop" ,[start:from,stop:to])
}
Your question may be a duplicate. See Convert datetime in to date. But if anyone has more recent information, that would be great.
If that doesn't help, you can hack it the way I might, with a BETWEEN restriction, e.g.
def today = new Date()
def ymdFmt = new java.text.SimpleDateFormat("yyyy-MM-dd")
def dateYmd = ymdFmt.format(today)
def dateTimeFormat = new java.text.SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
def startDate = dateTimeFormat.parse("${dateYmd} 00:00:00");
def endDate = dateTimeFormat.parse("${dateYmd} 23:59:59");
MyDomain.findAll("from MyDomain where dateCreated between ? and ?", [startDate, endDate])
It's definitely not pretty, but it may get you where you're going.
I figured it out.
I used DateGroovyMethods.clearTime to clear the time value before saving.
You can use the DB type date not datetime , in the filed type

In my domain I have
Time startTime
Time endTime
In my controller I need to covert the time from the view which is in a format of HH:MM to the acceptable format to submit to the domain. I have installed the plugin Joda-Time but I've come a bit stuck.
def startTime = params.startTime
def fmt_in = DateTimeFormat.forPattern("HH:mm:ss")
def fmt_out = ISODateTimeFormat.dateTime()
println fmt_out.print(fmt_in.parseDateTime(startTime))
sorry, newbie to groovy grails
After parsing for DateTime, you need to transform it to the desired type. For date and time without considering timezone I suggest you to use LocalDateTime and LocalTime.
def formatter = DateTimeFormat.forPattern("HH:mm:ss")
LocalTime time = formatter.parseLocalDateTime(params.startTime).toLocalTime()
Lets say, i have a "Book" class with field "availableOn"(as shown below).
class Book {
String availableOn;
}
The fields holds values
"All days" or
String representation of a date. For example "13/06/2012"
How can i get all Books that are available within next two days? The below code would throw an exception ("java.util.Date cannot be cast to java.lang.String")
def books = c.list(){
between('availableOn', new Date(), new Date() + 2)
}
PS : Am working on a legacy DB, and so am not suppose to change the schema :(
I think there are 2 problems which the between statement will have:
availableOn cannot be converted to a Date for comparison when its value is All days
Even when availableOn has a date value in it, it is not converted to a Date for the comparison
I'd try something along the lines of this:
def now = new Date()
def books = Book.findAllByAvailableNotEqual("All days").findAll { book ->
Date.parse('dd/MM/yyyy', book.availableOn) > now && Date.parse('dd/MM/yyyy', book.availableOn) < now+2
}
Clearly, this can be done in a nicer way (adding some methods to the domain class for example), but this should illustrate my idea...
I don't have a criteria based solution, but you can try something like this:
Book.executeQuery(
"select book from Book book where book.availableOn = :availableOn or to_date(book.availableOn, :format) between (:startDate, :endDate) ",
[availableOn:"All days", format: "dd/MM/yyyy", startDate: startDate, endDate:endDate])
The problem with my solution is that this query becomes DB dependent. to_date is an Oracle function. You may want to alter this to fit your database
You can use format on a date to get desired string format of it.
new Date().format('dd/MM/yyyy')
And your criteria would get modified to
def books = c.list(){
def todayDateStr = new Date().format('dd/MM/yyyy')
def twoDaysAfterTodayDateStr = (new Date()+2).format('dd/MM/yyyy')
or{
between('availableOn', todayDateStr, twoDaysAfterTodayDateStr)
eq 'availableOn', 'All Days'
}
}
Test if the str comparison works, otherwise other ways has to be used. Sending from phone, excuse my typos.
UPDATE
The above would fail in peculiar cases when dates are like "01/01/2013" and "07/11/2011".
Alternatively, you can use sqlRestriction but in that case it gets tightly coupled with the underlying database. Something like this can be done if Oracle db is used:
def books = c.list(){
def todayDateStr = new Date().format('dd/MM/yyyy')
def twoDaysAfterTodayDateStr = (new Date()+2).format('dd/MM/yyyy')
or{
sqlRestriction "to_date(available_on, 'DD/MM/YYYY') between to_date(todayDateStr, 'DD/MM/YYYY') and to_date(twoDaysAfterTodayDateStr, 'DD/MM/YYYY')"
eq 'availableOn', 'All Days'
}
}
I noticed that invoking service method with simple select makes MyDomain.class Date field update in DB (clears time). However enclosing the method with #Transactional(readOnly = true) doesn't update the date value.
Why the value is saved into DB?
Here is the service method
#Transactional(readOnly = true)
Date getDate()
{
Date date = null
date = MyDomain.executeQuery("select min(s.startDate) from MyDomain s where ....)[0]
print "Result: " + date
}
The object will only get updated in the database if it is somehow changed after it brought into the hibernate session (selected) and before the the session is closed (usually at the end of the method). Take a look at your object, and see how it might be modified in some way that you did not intend.
How to get last modified date of a sharepoint group.
how to get date when a user is added to a sharepoint group.
thanks for your help.

You can get the "Creation" and "Last Modified" Date through following Code:
SPList groupInformationList = SPContext.Current.Web.SiteUserInfoList;
SPListItem grpItem = groupInformationList.Items.GetItemById(group.ID); // Pass the ID of group
// OR, SPListItem grpItem = web.SiteUserInfoList.GetItemById(web.SiteGroups["group_name"].ID);
string groupCreationDate = Convert.ToDateTime(grpItem[SPBuiltInFieldId.Created]).ToString("MM/dd/yyyy hh:mm tt"); //Group Creation Date
string groupLastModifiedDate = Convert.ToDateTime(grpItem[SPBuiltInFieldId.Modified]).ToString("MM/dd/yyyy hh:mm tt"); // Group Modification Date
I do not know of an out of the box way to do this. The SPGroup and SPUserCollection classes do not contain dates. And even looking in the content database (which is unsupported), neither the Groups or GroupMembership tables have dates.
I need to update time info in a DateTime.
I get a string in the format "14" or "14:30" (for example), so I need to give it to Time parser to get the right hour. Then I need to update self.start_at which is a datetime which already has a time, but I need to update it.
self.start_at_hours = Time.parse(self.start_at_hours) # example 14:30:00
# NEED TO UPDATE self.start_at which is a datetime
I was using the change method on self.start_at but it only takes hour and minutes separated and I'm not sure what should I do.
Have you thought about doing somethings like this?
time_to_merge = Time.new
date_to_merge = Date.today
merged_datetime = DateTime.new(date_to_merge.year, date_to_merge.month,
date_to_merge.day, time_to_merge.hour,
time_to_merge.min, time_to_merge.sec)
For replacing time, the .change() method should work, like this:
my_datetime = my_datetime.change(hour: my_time.hour, min: my_time.min, sec: my_time.sec)
For adding time, try converting to seconds and then adding them:
my_datetime += my_time.seconds_since_midnight.seconds
