Class RANGE<T>

Range types are data types representing a range of values of some element type (called the range's subtype). Only available in Postgres. See the Postgres documentation for more details

Fallback policy: If this type is not supported, an error will be raised.

Example

// A range of integers
DataTypes.RANGE(DataTypes.INTEGER)
// A range of bigints
DataTypes.RANGE(DataTypes.BIGINT)
// A range of decimals
DataTypes.RANGE(DataTypes.DECIMAL)
// A range of timestamps
DataTypes.RANGE(DataTypes.DATE)
// A range of dates
DataTypes.RANGE(DataTypes.DATEONLY)

Type Parameters

T extends BaseNumberDataType | DATE | DATEONLY = INTEGER

Methods

`Protected`_checkOptionSupport

_checkOptionSupport(dialect: AbstractDialect): void
Override this method to emit an error or a warning if the Data Type, as it is configured, is not compatible with the current dialect.
Parameters
- dialect: AbstractDialect
  The dialect using this data type.
Returns void
Overrides ABSTRACT._checkOptionSupport
- Defined in core/src/abstract-dialect/data-types.ts:1910

`Protected`_construct

_construct<Constructor extends new () => DataTypes.ABSTRACT<any>>(
...args: ConstructorParameters<Constructor>,
): this
Type Parameters
- Constructor extends new () => DataTypes.ABSTRACT<any>
Parameters
- ...args: ConstructorParameters<Constructor>
Returns this
Inherited from ABSTRACT._construct
- Defined in core/src/abstract-dialect/data-types.ts:159

`Protected`_getDialect

_getDialect(): AbstractDialect
Returns AbstractDialect
Inherited from ABSTRACT._getDialect
- Defined in core/src/abstract-dialect/data-types.ts:108

acceptsNull

acceptsNull(): boolean
Whether this DataType wishes to handle NULL values itself. This is almost exclusively used by JSON and JSONB which serialize null as the JSON string 'null'.

Returns boolean
Inherited from ABSTRACT.acceptsNull
- Defined in core/src/abstract-dialect/data-types.ts:177

areValuesEqual

areValuesEqual(
value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>,
originalValue: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>,
): boolean
Parameters
- value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>
- originalValue: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>
Returns boolean
Inherited from ABSTRACT.areValuesEqual
- Defined in core/src/abstract-dialect/data-types.ts:169

belongsToDialect

belongsToDialect(dialect: AbstractDialect): boolean
Parameters
- dialect: AbstractDialect
Returns boolean
Inherited from ABSTRACT.belongsToDialect
- Defined in core/src/abstract-dialect/data-types.ts:291

clone

clone(): this
Returns a copy of this DataType, without usage context. Designed to re-use a DataType on another Model.

Returns this
Inherited from ABSTRACT.clone
- Defined in core/src/abstract-dialect/data-types.ts:333

escape

escape(value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>): string
Escapes a value for the purposes of inlining it in a SQL query. The resulting value will be inlined as-is with no further escaping.
Parameters
- value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>
  The value to escape.
Returns string
Inherited from ABSTRACT.escape
- Defined in core/src/abstract-dialect/data-types.ts:219

getBindParamSql

getBindParamSql(
value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>,
options: BindParamOptions,
): string
This method is called when AbstractQueryGenerator needs to add a bind parameter to a query it is building. This method allows for customizing both the SQL to add to the query, and convert the bind parameter value to a DB-compatible value.

If you only need to prepare the bind param value, implement toBindableValue instead.

This method must return the SQL to add to the query. You can obtain a bind parameter ID by calling BindParamOptions#bindParam with the value associated to that bind parameter.

An example of a data type that requires customizing the SQL is the GEOMETRY data type.
Parameters
- value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>
  The value to bind.
- options: BindParamOptions
  Options.
Returns string
Inherited from ABSTRACT.getBindParamSql
- Defined in core/src/abstract-dialect/data-types.ts:245

getDataTypeId

getDataTypeId(): string
Returns string
Inherited from ABSTRACT.getDataTypeId
- Defined in core/src/abstract-dialect/data-types.ts:97

parseDatabaseValue

parseDatabaseValue(_value: unknown): unknown
Called when a value is retrieved from the Database, and its DataType is specified. Used to normalize values from the database.

Note: It is also possible to do an initial parsing of a Database value using AbstractDialect#registerDataTypeParser. That normalization uses the type ID from the database instead of a Sequelize Data Type to determine which parser to use, and is called before this method.
Parameters
- _value: unknown
  The value to parse.
Returns unknown
Overrides ABSTRACT.parseDatabaseValue
- Defined in core/src/abstract-dialect/data-types.ts:1930

sanitize

sanitize(value: unknown): unknown
Used to normalize a value when Model#set is called. That is, when a user sets a value on a Model instance.
Parameters
- value: unknown
Returns unknown
Overrides ABSTRACT.sanitize
- Defined in core/src/abstract-dialect/data-types.ts:1934

toBindableValue

toBindableValue(
value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>,
): unknown
Converts a JS value to a value compatible with the connector library for this Data Type. Unlike escape, this value does not need to be escaped. It is passed separately to the database, which will handle escaping.
Parameters
- value: AcceptableTypeOf<T> | Rangable<AcceptableTypeOf<T>>
  The value to convert.
Returns unknown
Inherited from ABSTRACT.toBindableValue
- Defined in core/src/abstract-dialect/data-types.ts:257

toDialectDataType

toDialectDataType(dialect: AbstractDialect): this
Returns this DataType, using its dialect-specific subclass.
Parameters
- dialect: AbstractDialect
Returns this
Overrides ABSTRACT.toDialectDataType
- Defined in core/src/abstract-dialect/data-types.ts:1918

toSql

toSql(): string
Returns a SQL declaration of this data type. e.g. 'VARCHAR(255)', 'TEXT', etc…

Returns string
Overrides ABSTRACT.toSql
- Defined in core/src/abstract-dialect/data-types.ts:1972

toString

toString(): string
Returns string
Inherited from ABSTRACT.toString
- Defined in core/src/abstract-dialect/data-types.ts:261

validate

validate(value: any): void
Checks whether the JS value is compatible with (or can be converted to) the SQL data type. Throws if that is not the case.
Parameters
- value: any
Returns void
Overrides ABSTRACT.validate
- Defined in core/src/abstract-dialect/data-types.ts:1964

withUsageContext

withUsageContext(usageContext: DataTypeUseContext): this
Parameters
- usageContext: DataTypeUseContext
Returns this
Inherited from ABSTRACT.withUsageContext
- Defined in core/src/abstract-dialect/data-types.ts:339

`Static`getDataTypeId

getDataTypeId(): string
Returns string
Inherited from ABSTRACT.getDataTypeId
- Defined in core/src/abstract-dialect/data-types.ts:93

`Static`toString

toString(): string
Returns string
Inherited from ABSTRACT.toString
- Defined in core/src/abstract-dialect/data-types.ts:270
