SQL Server Reporting Service - Reference another dataset?
开发者_开发知识库I have two datasets in a SQL Server 2008 reporting services report. I need to attach a WHERE clause to the second one that will contain a value from the first one. How should I write that second query?
If I understand what you are asking, you should run a SUB query within the where clause.
SELECT title FROM books WHERE author_id IN (SELECT id FROM authors);
