Join Mark Niemann-Ross for an in-depth discussion in this video Correct information, wrong format, part of Database Clinic: SQLite.
- In this video, I'll show you how to use SQLite…to select the correct information,…but report in the wrong format.…I'll be using DB Browser for SQLite,…and I used the database we created for problem one,…and have opened it.…Let's go take a quick look at that data.…And here's the table.…You'll notice that it's still called second table,…and contains all the columns that we created in problem one.…
Let's take a look at the SQL that I've written in order…to generate the correct information, wrong format.…Now this is pretty simple SQL.…It's found in the example file searchSolution_1.sql,…and that's in the example files.…Lines one through seven are just a comment.…That's just there to identify what this file is,…and to help you understand what we're trying to do.…The meat of the SQL is lines 10 through 17,…and again this is fairly simple SQL.…
Lines 10 through 13 set up a select command,…and in the report that we create we are going to use…three columns, the County Name column,…and you can see that over here in the DB schema.…
