问题 I currently have a legacy database (SQL 2005) that generates hash strings for tokens. It does it like this... DECLARE @RowID INT DECLARE @hashString VARCHAR(128) SET @RowID = 12345 SET @salt= 0xD2779428A5328AF9 SET @hashBinary = HASHBYTES(('MD5', @salt + CAST(@RowID AS VARBINARY(30))) SET @hashString = sys.fn_varbintohexstr(@hashBinary) If I execute this, I my hash string looks like this: "0x69a947fd71b853485007f0d0be0763a5" Now, I need to replicate the same logic in C# so I can remove the

问题 Go easy on me, this is my first question ;) I've spent a lot of time looking, but I haven't found what I'm looking for. I've got an intranet based reporting tool (VB.Net + ASP.Net Integrated Windows Authentication) that looks up users and managers from a SQL Server 2005 table to roll up the reporting to manager level.

The values of these attributes is unique. I want to pivot this table and get the following output - Id Atr1 Atr2 Atr3 A1 A1V1 A1V2 A1V3 A2 A2V1 A2V2 A2V3 How do I do this ?

问题 Is there a simple way to insert multiple rows and increment a particular field, using SQL Server 2005?

For instance, consider the following table and data... CREATE TABLE #TEMPTABLE ( [PKID] INT IDENTITY, [FKID] INT, [MYTEXT] VARCHAR(10), [SEQUENCE] INT ) INSERT INTO #TEMPTABLE ([FKID], [MYTEXT],

问题 I've got a person table that contains an error code field that can contain multiple error codes (001, 002, 003...). I know that's a schema problem but this is a vendor application and I have no control over the schema, so I have to work with what I've got. There is also a Error table that contains ErrorCode (char(3)) and Descript (char(1000)). In my query the Person.ErrorCode is joined to the Error.ErrorCode to get the value of the corresponding description. For person records where there is
