问题 I have been using SQL Server CE for a while. In that database the table names were like UserPosts , UserProfile . But after my upgrade from SQL Server CE to SQL Server the names are edited to dbo.UserPosts , dbo.UserProfile . And also the names of columns are wrapped in square brackets like: [UserProfile] . Why is this bracket used? 回答1: Brackets are used to surround names in SQL Server (they server the same purpose as double quotes). For names that consist of alphanumeric characters and

问题 I have a stored procedure that I need to convert to a standard query. Since I'm using SQL Server Compact, no stored procedures. Here is my stored procedure: declare @colu nvarchar (max) , @hour int set @hour = DATEPART(HH, GETDATE() ) select @hour select @colu = case when @hour=24 then '[12:00AM(00:00)]' enter code here when @hour >12 and @hour <24 then '['+ convert(varchar,@hour-12) +':00PM('+ convert(nvarchar ,@hour) +':00)]' when @hour=12 then '[12:00PM(12:00)]' when @hour <12 and @hour >9

问题 An earlier problem with this query was resolved here but now this query: ...fails with: Why? It worked once (it was the fix for the earlier question linked to above).
