varbinary

问题 I need to store binary files in a varbinary(max) column on SQL Server 2005 like this: FileInfo FileInfoId int, PK, identity FileText varchar(max) (can be null) FileCreatedDate datetime etc. FileContent FileInfoId int, PK, FK FileContent varbinary(max) FileInfo has a one to one relationship with FileContent.

问题 I have a table in which the userpassword field have varbinary datatype, So I'm confused that in which form should I save the data into userpassword field because when I save varchar data it gave me error. 回答1: A varbinary column can store anything. To store a string in it, you'd have to cast it to varbinary : declare @t table (id int identity, pwd varbinary(50)) insert into @t (pwd) values (cast('secret' as varbinary(50))) But for a password, a varbinary column usually stores a hash of some

问题 I was reading on internet these statements about SQL Server data types: VARBINARY(MAX) - Binary strings with a variable length can store up to 2^31-1 bytes. IMAGE - Binary strings with a variable length up to 2^31-1 (2,147,483,647) bytes. Is there a really big technical difference between VARBINARY(MAX) and IMAGE data types? If there is a difference: do we have to customize how ADO.NET inserts and updates image data field in SQL Server? 回答1: They store the same data: this is as far as it goes

问题 I am saving files (any type ) in a SQL table, using a varbinary(max) , I find out that the max usage of this datatype is 8000, but what does the 8000 mean?

I start testing and the maximum file that I can store is 29.9 MB. If I choose a larger file a get a SQLException. String or binary data would be truncated. The statement has been terminated. 回答1:

问题 I'm having a very particular performance problem at work! In the system we're using there's a table that holds information about the current workflow process. One of the fields holds a spreadsheet that contains metadata about the process (don't ask me why!! and NO I CAN'T CHANGE IT!!) The problem is that this spreadsheet is stored in an IMAGE field in an SQL Server 2005 (within a database set with SQL 2000 compatibility). This table currently has 22K+ lines and even a simple query like this:

问题 I have a table with a VARBINARY(MAX) field (SQL Server 2008 with FILESTREAM ) My requirement is that when I go to deploy to production, I can only supply my IT team with a group of SQL scripts to be executed in a certain order.
