问题 Tried calling the new column I made in my database via Razor, throwing an error in a different file. I am completely unsure what any of this means. Server Error in '/' Application.

Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Invalid column name

问题 In a previous question I wanted to know how I can use SQL to JOIN different XML elements based on an identifier. I was provided with several nice solutions as you can see here. Now I am in the process of adapting this solution to my actual data. Unfortunately I stumbled upon a new obstacle that was not present in the minimum viable example I provided in the linked question. In my actual data I also have several child elements of the same name. See the element <subElement> in the following

问题 I have a .bat (Windows command) file that includes invocations of SQLCMD and other commands. (Of course SQLCMD is sending my T-SQL code to SQL Server.) I want to detect certain conditions in the SQL code, and conditionally exit the entire batch file. I've tried various combinations of RAISERROR, THROW, and deliberate division by 0 (I'm not proud) along with various command line switches on SQLCMD and handling of errorlevel in the .bat file. I tried the answer to 5789568 but could not get it
