问题 I have a SQL Server DB that is about 13Gb with a 1.6Gb log file. When I back it up, however, it creates a 50Gb .bak file! Why is that?

问题 I am using SQL Server Management Studio to export the results of my query to text. I would like to export the results without the character NULL being printed between delimiters.

The Web version from my host provider costs about 13$ per 2 core packs, whereas the Standard edition is right around 200$. From my standpoint, we expect our database to be around 150-200GB in size, only few tables would take up most of that space. So my only concern is would the web version of SQL Server support this large database and not cause any performance issues to the end users

问题 I have an SQL Server 2008 table with a structure similar to the following: ID int PRIMARY KEY IDENTITY(1,1) Name nvarchar(100) LongText ntext What I am trying to achieve is simple. Before inserting data inside this table, I want to encrypt the LongText using AES_192 algorithm. I am using the following SP to encrypt data: create proc sp_Encrypt_LongText @rawText ntext = null, @encryptedText nvarchar(max) output as begin OPEN SYMMETRIC KEY Encryption_Symmetric_Key DECRYPTION BY CERTIFICATE
