Decimal precision can go to 24 places for a FLOAT. DOUBLE(M,D) A double precision floating-point number that cannot be unsigned. You can define the display length (M) and the number of decimals (D). This is not required and will default to 16,4, where 4 is the number of decimals...

FLOAT(p)A floating point number. MySQL uses thepvalue to determine whether to use FLOAT or DOUBLE for the resulting data type. Ifpis from 0 to 24, the data type becomes FLOAT(). Ifpis from 25 to 53, the data type becomes DOUBLE() ...
3.1.2Additional PL/SQL Constants for BINARY_FLOAT and BINARY_DOUBLE The SQL data typesBINARY_FLOATandBINARY_DOUBLErepresent single-precision and double-precision IEEE 754-format floating-point numbers, respectively. BINARY_FLOATandBINARY_DOUBLEcomputations do not raise exceptions, so you must check the...
JDBC 类型FLOAT基本上与 JDBC 类型DOUBLE相同。我们同时提供了FLOAT和DOUBLE,其目的是与以前的 API 实现一致。但这却有可能产生误导。FLOAT代表一个有 15 位尾数的“双精度”浮点数。 对应的 SQL 类型FLOAT,其定义由 SQL-92 给出。SQL-92 标准将FLOAT的精度留给实现去决定。但事实上,所有支持FLOAT类型的主流数据...
[5] 根据实现,SQL_FLOAT的精度可以是 24 或 53:如果为 24,则SQL_FLOAT数据类型与 SQL_REAL 相同;如果为 53,则SQL_FLOAT数据类型与SQL_DOUBLE相同。 [6] 在 ODBC3.x中,SQL 日期、时间和时间戳数据类型分别SQL_TYPE_DATE、SQL_TYPE_TIME和SQL_TYPE_TIMESTAMP;在 ODBC2.x中,数据类型SQL_DATE、SQL_TIME...
OceanBase的MySQL模式兼容MySQL 5.7的绝大部分数据类型,包括数值类型(如INT、BIGINT、FLOAT、DOUBLE等)、日期和时间类型(如DATETIME、TIMESTAMP等)、字符串类型(如CHAR、VARCHAR等)以及其他复杂数据类型(如ENUM、SET、JSON等)。此外,OceanBase还支持空间数据类型,这在某些特定应用场景中非常有用。 OceanBase 数据库支持的...
