Hi,
I am a datawarehouse consultant working on the front end of the warehouse. I work with B.I tools. I do not actually do any coding in sql but would love to start off with some simple queries.( I am in a position to write some simple queries and definetly can intrepret even big queries)
My problem is that I never got a chance to write queries and so I would love to start off writing queries on a dummy database of some online tutorial. My basic needs are writing subqueries and writing queries involving multiple joins.
I have checked some online tutorials but they just go over some basic stuff. I want to know if there is any free online tutorial out there which can give me some comprehensive training in sql queries.
Any help would be greatly appreciated.
Thanks,
