u sql - Create a View with the identifier as a variable on u-sql -


i create view using u-sql. name of view can defined @ compile time using declare function.

visual studio throws syntax error when try use variable in create view statement.

is there workaround this?

u-sql not support dynamic u-sql @ point although if feel important missing feature post feature request here:

https://feedback.azure.com/forums/327234-data-lake

it looks there similar request can vote here.

as workaround, generate u-sql dynamically run script separately either manually or using 1 of sdks eg using powershell, .net. simple example:

//dynamic u-sql declare @viewname string = "dbo.vw_yourviewname";  // create dynamic u-sql @usql =          select *          ( values             ( "use database yourdatabase;"),             ( string.format("drop view if exists {0};", @viewname)),             ( string.format("create view if not exists {0} extract col1 int, col2 string, col3 string, col4 string, col5 string \"/input/input44.txt\" using extractors.csv();", @viewname))              )  x (usql);   // output statements in correct sort order output @usql "/output/dynamic.usql"  using outputters.text(delimiter:' ', quoting:false);

other examples of dynamic u-sql (or more precisely, u-sql generated dynamically) here , here.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
