问题 I want to output all the possible combination in two tables without using cartesian join or cross join. Is this possible? 回答1: I want to output all the possible combination in two tables without using cartesian join or cross join. Is this possible? By a strict definition level, it is not possible. Why? Because the definition of a Cartesian product is exactly what you describe (the term "Cartesian join" is not often used but is a synonym for "Cartesian product"). Hence, any method that you use

问题 I have an wpf app that creates a database to file. Just uses (LocalDB)/v11.0 in the connection string not .SQLExpress. If i go in project properties and go to publish tab and click on Application files, i tell it to Exclude SQlServer.Dmf.dll and yet when I publish it still ask for that dll. Why is this?

问题 As a follow up on insert control characters in nvarchar or varchar from SQL script? : What is the difference between the 0x prefixed hexadecimal constants and the decimal ones in the below SQL script? It looks like the 0x prefixed ones don't deliver integers. I'm probably in for another duh moment this evening, so please enlighten me (: select char(0x64) charx64, char(0100) char100, nchar(0x64) ncharx64, nchar(0100) nchar100, char(0x6564) charx6564, char(025956) char25956, nchar(0x6564)

问题 Following query correctly displays all current/prospective customers' record regardless of whether an order was placed by him/her or not. But the YesNO alias of the SELECT statement below is always returning 1 even when in some cases o.OrderID is null (i.e., when a perspective customer has not placed an order yet). Why? I think the CASE statement below is correct (as shown in this response as well). I'm using SQL Server 2012 . NOTE : Please keep in mind that although the OrderID is a PK it

问题 I have a pair of linked SQL servers: ServerA and ServerB. I want to write a simple INSERT INTO SELECT statement which will copy a row from ServerA's database to ServerB's database. ServerB's database was copied directly from ServerA's, and so they should have the exact same basic structure (same column names, etc.) The problem is that when I try to execute the following statement: INSERT INTO [ServerB].[data_collection].[dbo].[table1] SELECT * FROM [ServerA].[data_collection].[dbo].[table1] I
