sql-server

问题 I have not been able to find a way to join 4 or more tables using outer join in MSAccess. It works in SQL Server, but not Access. I don't believe it is possible. I have tables A, B, C, D and E. I need to join the tables like so: A left outer join B A left outer join C A inner join D B inner join E Access won't let you use conventional joins in the where clause when you use LEFT/RIGHT/INNER JOINS in the FROM clause. If you do, I get very, very vague errors like "JOIN expression not supported"

问题 Here is a sample code of using the SqlDataReader : // Working with SQLServer and C# // Retrieve all rows cmd.CommandText = "SELECT some_field FROM data"; using (var reader = cmd.ExecuteReader()) { while (reader.Read()) { Console.WriteLine(reader.GetString(0)); } } EDIT : I mean I want to understand whether there is the same mechanism when retrieving data from database in a while-loop (in case of SqlDataReader ) as it does when working with the SQLite. // working with SQLite and Java if

问题 I need to shift data(columns) to left side if first columns(left side columns) have 0 value and NULL should be added in right side columns.

问题 Consider the following two tables: Project ( id, project_name) Status ( id, id_project, status_name) Where Status contains all statuses in which a Project has been. Lets say we want to query all projects for which the latest status has the name "new". The Sql query that I come up with is: SELECT q.id_project FROM status q WHERE q.status_name like 'new' AND q.id IN ( SELECT TOP 1 sq.id from status sq WHERE q.id_project = sq.id_project ORDER BY sq.id DESC ) I'm trying to replicate the above
