Transaction isolation and reading from multiple tables on SQL Server Express and SQL Server 2005
问题 I have a database with a main table (lets call it Owner) and several sub tables with holdings (like Cars, Books etc). For example: Owner has columns: owner_id, name Cars has columns: owner_id (foreign key), brand Books has columns: owner_id (foreign key), title, author My program should calculate statistics like How many BMW owners also owns a Harry Potter book using various third party libraries. I want to read all rows from all tables at the same time and then do the analysis in non-sql
