I think it’s my WordPress Theme that’s making them do that. I also know the result images are really small, I apologize. Rather than updating the data per each example, I did transformations inline to help you understand what is going on. In the examples below, I am comparing the same customer from stage (dbo.stgTblCustomer) and target (dbo.tblCustomer) tables. The only recommended ones from Microsoft are SHA2_256 and SHA2_512. It’s important to note that there are deprecated, but still working, algorithms used: MD2, MD4, MD5, SHA, and SHA1. The T-SQL function used in the examples below will be HASHBYTES(). Algorithm examples are MD2, MD5, SHA, and SHA_256.Ī hash value can vary in the way it looks, depending on the algorithm you use. If that doesn't suit you, our users have ranked more than 25 alternatives to SQL. The best Mac alternative is DBeaver, which is both free and Open Source.
SQL Server Management Studio is not available for Mac but there are plenty of alternatives that runs on macOS with similar functionality. To generate a hash value, a hash function or algorithm is used.Ī hash function or algorithm defines the process of how a hash value is created. SQL Server Management Studio Alternatives for Mac. In a nutshell, it’s a string (hash value) that defines some data (like a string letters). What’s a Hash Value?įirst of all, what is a hash value? Microsoft defines a hash value as ‘…a numeric value of a fixed length that uniquely identifies data’. Or if you just want to read this blog, that’s cool too. I’m coming from a data warehousing perspective on this because there may be a need to switch the process of where row-by-row processing happens this is more evident when processing 100k records where type 1 or 2 attributes occur. The one reason I would say is to help with performance. You may ask why there is a need to generate a hash value to compare records when comparing fields would suffice.
