Numeric types can be divided into two categories by precision:
- Exact data types
- Integer data types: TINYINT, SAMLLINT, MEDIUMINT, INTEGER, and BIGINT.
- Fixed-point data types: DECIMAL and NUMERIC.
- Approximate data types: FLOAT, REAL, and DOUBLE PRECISIONs.
Overall, the data types supported in Distributed Relational Database Service (DRDS) are consistent with those of MySQL. For more information, see Data types in MySQL.
