Exception in thread "main" com.datastax.driver.core.exceptions.InvalidQueryException: Unknown definition referenced in PRIMARY KEY

Question

I am trying to create tables in Cassandra using JAVA API.

This query works perfectly and creates the table.

String query = "CREATE TABLE IF NOT EXISTS TopQuery1(term text , "
            +"year text , "
            +"month text , "
            +"day text , "
            +"hour text , "
            +"count counter,"
            +"PRIMARY KEY (\"term\", \"year\", \"month\", \"day\", \"hour\" ));";

But when I execute the following query it throws an error.

String query = "CREATE TABLE IF NOT EXISTS TopQuery2(term text , "
            +"year text , "
            +"month text , "
            +"day text , "
            +"hour text , "
            +"dayOfYear int , "
            +"weekOfYear int , "
            +"ProductCount int , "
            +"count counter,"
            +"PRIMARY KEY (\"term\", \"year\", \"month\", \"day\", \"hour\", \"dayOfYear\", \"weekOfYear\", \"ProductCount\"));";      

This is the error :

I seriously don't understand what I am missing.

Answer 1

Column names are case-insensitive by default, unless you enclose them in double quotes.

When you define the column you don't use quotes, so it's called dayofyear:

+"dayOfYear int , "

But in your primary key definition you use quotes, so it's looking for a column called dayOfYear:

+"PRIMARY KEY (... \"dayOfYear\" ...)";

Either use quotes everywhere or nowhere (depending on whether case sensitivity matters).
