What are the Different Data Types in BigQuery?
BigQuery supports a variety of data types including Bytes, Boolean, Decimal, Float, Timestamp, Integer, and Struct. Each data type has its own unique characteristics and uses. For instance, Bytes represent variable-length data in raw bytes, not Unicode characters, while Boolean can be TRUE or FALSE, or NULL.
- Bytes: This data type represents variable-length data in raw bytes, not Unicode characters. Strings and bytes are separate and cannot be used interchangeably.
- Boolean: Boolean values can be TRUE or FALSE, or NULL. They are commonly used when exporting data from applications or other software solutions.
- Decimal: Decimal uses 16 Bytes for storage and can represent decimal figures accurately, making it an ideal choice for financial and accounting applications.
How Does BigQuery Handle Float and Timestamp Data Types?
Float is an exact data type in BigQuery, with FLOAT64 being an approximate data type. On the other hand, Timestamp refers to an absolute point in time, and BigQuery interprets any timezone information and represents the time internally as a UTC timestamp.
- Float: In BigQuery, FLOAT64 is an approximate data type, while NUMERIC may be a better match for FLOAT type.
- Timestamp: This data type refers to an absolute point in time. BigQuery interprets any timezone information and represents the time internally as a UTC timestamp.
What is the Role of Integer and Struct Data Types in BigQuery?
Integer represents signed 64-bit integers and is used for whole numbers, both positive and negative. Struct, on the other hand, has attributes in Key-value Pairs, and multiple attributes generally have discrete values of their own in each record.
- Integer: This data type represents signed 64-bit integers, and is used for whole numbers, both positive and negative.
- Struct: Struct has attributes in Key-value Pairs, and multiple attributes generally have discrete values of their own in each record.
Does BigQuery Support JSON Data Format?
Yes, BigQuery supports JSON, a data format widely used in BigQuery. JSON is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.
