We allow aliases that can be used interchangeably with the primary data types. However, while these aliases can be used, they will be mapped to their corresponding primary data types during data processing.Here, we’ll discuss the numeric data type aliases:
The DOUBLE alias is used to define DOUBLE PRECISION floating-point numbers. For example:
CREATE TABLE DoubleExample ( measurement DOUBLE,);-- Functionally the same as the previous tableCREATE TABLE DoubleEquivalent ( measurement DOUBLE PRECISION,);
When you use DOUBLE, it’s stored and treated as DOUBLE PRECISION.
