A quick and easy way to do this is to extract the number of days or weeks that have taken place since the start of each respective period (“Current” and “Previous”) using some of the same SQL logic that was used in the initial block setup. Redshift is a one of the most popular data warehousing solution, thousands of companies running millions of ETL jobs everyday. Non-compliant dialects of SQL, such as Transact-SQL, are forced to resort to proprietary functions like DATEADD() and DATEDIFF() in order to work with dates and times, and cannot handle more complex data types at all. You could export and import data, but another option is to create a linked server from SQL Server to Redshift. General Information 1. I had to solve a similar problem recently on Redshift where I only had read access and thus needed a purely SQL-based solution (no stored procedures) to getting a row for every hour in a date range as a starting point for my result set. This book also contains all of the SQL you need to query it with ease. Postgres datediff. Another quick Data Analysis eXpressions (DAX) update, given that I’ve been playing about with PowerPivot again this week. I'm not sure why you've felt the need to divide abc by 1.
