Question

I’m using one of my MySQL database tables as an actual table, with times of the day as each column, and one column called day. You guessed it, in day it says the day of the week, and in the rest of the cells it says what is happening at that time.

What I want to do is only show the cells that have value in it. In my case, I’m always going to have all the rows and 2 columns full. The 2 columns are ‘day’ and ’19:00′, however in the future I might add values for ’18:00′ etc.

So, how can I only SELECT the columns and rows which have data in them? Some type of ‘WHERE: there is data’?

Thanks!

From what I gathere you are looking something along the lines of

WHERE col1 IS NOT NULL

But it would be helpful if you could elaborate more on your schema, especially if you could draw a sample table.
