date

问题 I need to insert data to a given external table which should be partitioned by the inserted date. My question is how is Hive handling the timestamp generation? When I select a timestamp for all inserted records like this: WITH delta_insert AS ( SELECT trg.*, from_unixtime(unix_timestamp()) AS generic_timestamp FROM target_table trg ) SELECT * FROM delta_insert; Will the timestamp always be identical for all records, even if the query takes a lot of time to un? Or should I alternatively only

问题 I would like my online shop to be deactivated or activated for a certain period of time. When the shop is deactivated, you can see the products, but can't put them in the shopping cart. If you already have things in your shopping cart, you can't checkout and pay. Despite all this, you can see the products, but you can't buy them. Shop time would be as follows: Online: Monday to Sunday from 12 am to 22 pm Offline: the remaining time is to be deactivated Is that possible? I've already found a

问题 I am trying to get both week number and year from a date object in R. Until then, I did it separately : I used isoweek() function to extract week and year() function to extract year. So that my data.frame has 3 variables : date, week, year This is working except for beginning/end of year : for example, 2015 has 53 weeks and January 1st, 2016 belongs to the 53rd week of 2015 ... but with my code, it is such that 1/1/2016 is week 53 but year 2016 whereas I would like it to be week 53 in year

问题 Manipulating Dates causing me some issues. I've created some Java code that reads a document from a Notes DB then populates some fields in a Java Object with values from the Notes Document. The Notes Document contains a DataTime field "ExpPayDate" and I want to store it in the Java Object, but get a syntax error in the Java Editor. My code looks like this: for (int n = 1 ; n < col.getCount(); n++){ Document pDoc = col.getNthDocument(n); PaymentItem pItem = new PaymentItem(); Date pDate = pDoc
