public enum SysDataType
extends Enum<SysDataType>
implements PlasmaEnum

This generated Enumeration represents the domain model enumeration SysDataType which is part of namespace http://org.plasma/sdo/mysql/5_5 as defined within the Configuration.

* Generated SDO enumerations embody not only logical-name literals but also physical or instance names, which are often shorter (possibly abbreviated) and applicable as a data-store space-saving device. Application programs should typically use the physical or instance name for an enumeration literal when setting a data object property which is constrained by an enumeration.

SMALLINT

public static final SysDataType SMALLINT

A small integer. The signed range is -32768 to 32767. The unsigned range is 0 to 65535.

Holds the logical and physical names for literal SMALLINT.

MEDIUMINT

public static final SysDataType MEDIUMINT

A medium-sized integer. The signed range is -8388608 to 8388607. The unsigned range is 0 to 16777215.

Holds the logical and physical names for literal MEDIUMINT.

INT

public static final SysDataType INT

A normal-size integer. The signed range is -2147483648 to 2147483647. The unsigned range is 0 to 4294967295.

Holds the logical and physical names for literal INT.

INTEGER

public static final SysDataType INTEGER

This type is a synonym for INT.

Holds the logical and physical names for literal INTEGER.

BIGINT

public static final SysDataType BIGINT

A large integer. The signed range is -9223372036854775808 to 9223372036854775807. The unsigned range is 0 to 18446744073709551615. SERIAL is an alias for BIGINT UNSIGNED NOT NULL AUTO_INCREME NT UNIQUE. Some things you should be aware of with respect to BIGINT co lumns: All arithmetic is done using signed BIGINT or DOUBLE values , so you should not use unsigned big integers larger than 9223372036854775807 (63 bits) except with bit functions! If you do that, some of the last digits in the result may be wrong because of rounding errors when converting a BIGINT value to a DOUBLE. MySQL can handle BIGINT in the following cases: When using integers to store large unsigned values in a BIGI NT column. In MIN(col_name) or MAX(col_name), where col_name refers to a BIGINT column. When using operators (+, -, *, and so on) where both operand s are integers. You can always store an exact integer value in a BIGINT colu mn by storing it using a string. In this case, MySQL performs a string-to-number conversion that involves no intermediate double-precision representation. The -, +, and * operators use BIGINT arithmetic when both op erands are integer values. This means that if you multiply two big integers (or results from functions that return integers), you may get unexpected results when the result is larger than 9223372036854775807.

Holds the logical and physical names for literal BIGINT.

DECIMAL

public static final SysDataType DECIMAL

A packed ?exact? fixed-point number. M is the total number of digits (the precision) and D is the number of digits after the decimal point (the scale). The decimal point and (for negative numbers) the ?-? sign are not counted in M. If D is 0, values have no decimal point or fractional part. The maximum number of digits (M) for DECIMAL is 65. The maximum number of supported decimals (D) is 30. If D is omitted, the default is 0. If M is omitted, the default is 10. UNSIGNED, if specified, disallows negative values. All basic calculations (+, -, *, /) with DECIMAL columns are done with a precision of 65 digits.

Holds the logical and physical names for literal DECIMAL.

DEC

FIXED

public static final SysDataType FIXED

These types are synonyms for DECIMAL. The FIXED synonym is available for compatibility with other database systems.

Holds the logical and physical names for literal FIXED.

FLOAT

public static final SysDataType FLOAT

A small (single-precision) floating-point number. Permissible values are -3.402823466E+38 to -1.175494351E-38, 0, and 1.175494351E-38 to 3.402823466E+38. These are the theoretical limits, based on the IEEE standard. The actual range might be slightly smaller depending on your hardware or operating system. M is the total number of digits and D is the number of digit s following the decimal point. If M and D are omitted, values are stored to the limits permitted by the hardware. A single-precision floating-point number is accurate to approximately 7 decimal places. UNSIGNED, if specified, disallows negative values. Using FLOAT might give you some unexpected problems because all calculations in MySQL are done with double precision

Holds the logical and physical names for literal FLOAT.

DOUBLE

public static final SysDataType DOUBLE

A normal-size (double-precision) floating-point number. Permissible values are -1.7976931348623157E+308 to -2.2250738585072014E-308, 0, and 2.2250738585072014E-308 to 1.7976931348623157E+308. These are the theoretical limits, based on the IEEE standard. The actual range might be slightly smaller depending on your hardware or operating system. M is the total number of digits and D is the number of digit s following the decimal point. If M and D are omitted, values are stored to the limits permitted by the hardware. A double-precision floating-point number is accurate to approximately 15 decimal places. UNSIGNED, if specified, disallows negative values.

Holds the logical and physical names for literal DOUBLE.

DOUBLE__PRECISION

public static final SysDataType DOUBLE__PRECISION

These types are synonyms for DOUBLE. Exception: If the REAL_AS_FLOAT SQL mode is enabled, REAL is a synonym for FLOAT rather than DOUBLE.

Holds the logical and physical names for literal DOUBLE_PRECISION.

DATE

public static final SysDataType DATE

A date. The supported range is '1000-01-01' to '9999-12-31'. MySQL displays DATE values in 'YYYY-MM-DD' format, but permits assignment of values to DATE columns using either strings or numbers.

Holds the logical and physical names for literal DATE.

DATETIME

public static final SysDataType DATETIME

A date and time combination. The supported range is '1000- 01-01 00:00:00' to '9999-12-31 23:59:59'. MySQL displays DATETIME values in 'YYYY-MM-DD HH:MM:SS' format, but permits assignment of values to DATETIME columns using either strings or numbers.

Holds the logical and physical names for literal DATETIME.

TIMESTAMP

public static final SysDataType TIMESTAMP

A timestamp. The range is '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC. TIMESTAMP values are stored as the number of seconds since the epoch ('1970-01-01 00:00:00' UTC). A TIMESTAMP cannot represent the value '1970-01-01 00:00:00' because that is equivalent to 0 seconds from the epoch and the value 0 is reserved for representing '0000-00-00 00:00:00', the zero TIMESTAMP value. Unless specified otherwise, the first TIMESTAMP column in a table is defined to be automatically set to the date and time of the most recent modification if not explicitly assigned a value. This makes TIMESTAMP useful for recording the timestamp of an INSERT or UPDATE operation. You can also set any TIMESTAMP column to the current date and time by assigning it a NULL value, unless it has been defined with the NULL attribute to permit NULL values.

Holds the logical and physical names for literal TIMESTAMP.

TIME

public static final SysDataType TIME

A time. The range is '-838:59:59' to '838:59:59'. MySQL displays TIME values in 'HH:MM:SS' format, but permits assignment of values to TIME columns using either strings or numbers.

Holds the logical and physical names for literal TIME.

YEAR

public static final SysDataType YEAR

A year in two-digit or four-digit format. The default is four-digit format. YEAR(2) or YEAR(4) differ in display format, but have the same range of values. In four-digit format, values display as 1901 to 2155, and 0000. In two- digit format, values display as 70 to 69, representing years from 1970 to 2069. MySQL displays YEAR values in YYYY or YYformat, but permits assignment of values to YEAR columns using either strings or numbers.

Holds the logical and physical names for literal YEAR.
