sql-server-express

问题 I'm just starting out with SQL Server 2008 Express and spent the last hour or so trying out some basic queries. How does SQL scripting (correct term?) compare to general computer programming? Is writing SQL queries as involved, lengthy to learn, needs as much practice, etc. as software development?

问题 I can't find any examples on creating a SQL Server RDS instance in CloudFormation, so I took an educated guess using an example for MySQL. Here's what I came up with: { "AWSTemplateFormatVersion" : "2010-09-09", "Resources" : { "DBInstance" : { "Type": "AWS::RDS::DBInstance", "Properties": { "DBInstanceIdentifier" : "test-db", "Engine" : "sqlserver-ex", "Port" : "1433", "DBInstanceClass" : "db.t1.micro", "AllocatedStorage" : "30", "MasterUsername" : "sa", "MasterUserPassword" : "password" } }

问题 Here is my table. Price Volume ------------------ 60 0 70 10 80 0 90 0 100 40 200 40 300 40 400 0 500 50 600 60 It is ordered by Price. I need to choose all rows before two consecutive zeros in Volume column. So the result should look like Price Volume ------------------ 100 40 200 40 300 40 400 0 500 50 600 60 I really do not know where to start with this type of query. I could only think go pulling data into C# and the loading back into table. Regards, 回答1: You didn't state your DBMS so

问题 I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service.
