Built-in data types
Supported by ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The SQL standard and most RBDMS agree on a set of well-known primitive data types with a different set of names and variations. These include the following groups of types:
- Numeric integers: TINYINT, SMALLINT, INTEGER, BIGINT
- Numeric floats: REAL, DOUBLE, FLOAT
- Numeric decimals: NUMERIC, DECIMAL
- Strings of fixed length: CHAR
- Strings of variable length: VARCHAR, CLOB
- Binary strings of fixed length: BINARY
- Binary strings of variable length: VARBINARY, BLOB
- Temporal data types: DATE, TIME, TIMESTAMP
In addition to the above primitives, there are also a few more specialised data types that are frequently seen in RDBMS, including:
