INTEGER data type The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. INTERVAL data type The INTERVAL data type stores a value that represents a span of time. INTERVAL types are divided into two classes:year-month...
The first stage in creating a histogram is to "bin" the data range, or divide it into a series of intervals, and then count how many values fall into each interval. The bins are often defined as a series of discrete intervals that don't overlap. The bins must be close together and ...
