Hello, I have a table similar to the following: id probe value 1 asdf 10 1 qwer 20 1 zxcv 30 2 asdf 40 2 qwer 50 2 zxcv 60 I would like to create a stored procedure or function that will make a view with the data as follows: 1 2 asdf 10 40 qwer 20 50 zxcv 30 60 Does anyone know how to do this? I am attempting to make a stored procedure that... 1. SELECT all distinct "id"s 2. FOR LOOP to iterate over each "id", SELECT probe, value WHERE id=<current id> 3. JOIN resulting table to table from previous iteration of the FOR loop Unfortunately, I am not sure if this is a good way to do this. And I am not familiar with stored procedure syntax. Can anyone help with this?
