To use code snippets, type in some combination of letters and hit Alt-C. Those letters then expand into a SQL statement. By default you have sf (select * from <blank> limit 1000), and sfw (select * from <blank> where <blank> limit = 1000). But you can add your own, which is where they really shine. Use them for things you type again and again.https://tomroth.dev/sql-stats/Sat, 26 Jan 2019 00:00:00 +0000https://tomroth.dev/sql-stats/I worked with a large table, with a thousand numeric columns, and some of them were dodgy and I wanted to know which. It would help to find basic summary statistics, like the min, max and mean of each column, so let’s do that now. What to do? Link to heading I really didn’t want to do this: select min(c1), max(c1), mean(c1), min(c2), max(c2), mean(c2), min(c3) -- and so on for 1000 columns from xyz The alternate idea: write SQL, that generates SQL!
