nosql - IN operator in Cassandra doesn't work for table having a column with type-collection(Map or List) -


I am working on the cassandra to know how it works Some strange when using the IN operator Talked. Example:

Table: Create table test_time (name text, age, time, time, time id, "timestamp" timestamp, primary key ((name, age), time))

I have inserted some dummy data in the operator as follows: test_time to SELECT * where name = "9" and age = 81 and time IN (c7c88000-190e-11e4-8000- 000000000000, c7c88000-190e-11e4-7000-000000000000);

It worked properly.

Then, a column type was added to map . The table will look like this: create test test_time (Name text, age, time, time-time, name_age map, lit, text, interval, timestamp, timestamp, primary key ((name, age), time) / Code> On executing the same question, I found the following error: Bad request: The main part can not be restricted in the primary relationship in these relations because the query is selected by the archive

above From the examples, we can say, if the operator has any column of type collection (map or list) in the table, then it does not work.

I do not understand why this happens, please tell me if I am missing anything. thank you in advanced.

Yes ... this is a limitation, you can do the following:

  1. Select ... from where name = '9' and age = 81 and time & gt; X and time & lt; Y
  2. Select [Column Excluding Column] ... where name = '9' and age = 81 more time (...)

You can then filter the client side, or do any other query.

It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help?

There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
