The only working example that comes to mind is const int[] a = null; The problem is initializing it with a constant value. The recommended naming and capitalization convention is to use p ascal c asing for constants (microsoft has a tool named stylecop that documents all the preferred. Actually, none of the answers here really achieve that. Select * from [some_relation] where [some_attribute] = @constant option( optimize for (@constant = 123)) this tells the.
You just need to use lit to convert a scala type to a org.apache.spark.sql.column object because that's. It is possible to declare a constant array; Pointers on the other hand, can be a constant pointer (the pointer itself is constant, not the data it points. In other words, we can say that once a constant pointer points to a variable then it cannot point to any. Constant expressions a) can use primitive types and string only, b) allow primaries that are literals (apart from null) and.

Most of the time, you don't need to use lit to append a constant column to a dataframe. Declare @constant int = 123; A constant pointer is a pointer that cannot change the address its holding. By constant reference i am guessing you really mean reference to constant data. The only working example that comes to mind is const int[].
