Join Bill Weinman for an in-depth discussion in this video Flow control with CASE, part of MySQL Essential Training (2014).
…MySQL supports the standard SQL conditional expression syntax.…This is not really a function, but I'm…covering it here because it's important to understand it.…The syntax is a little cumbersome, but here's how it works.…We're going to use the scratch data base for…this, and we're going to create a little table.…We'll destroy it later.…Create table, and we'll call it booltest.…Bool for Boolean, and we'll give it two…simple columns integers, and we'll insert a couple…values into it just a one and a zero we're going to be using these as Boolean values.…
In MySQL a one is a Boolean true.…And a zero is a Boolean false.…Actually, zero is false.…And anything else is true.…But one is traditionally used for true.…And so we'll select from our booltest.…So we can see the values here.…And so, there's our table.…And it has two values in one row, a one and a zero.…We're going to use this to test our conditional expression.…So, I'm going to go ahead and create a SELECT statement here.…
And I'm going to put the body of the SELECT statement.…
