Understanding Object Field Types

For Liferay DXP 7.4 U24+

Object fields represent database columns that store specific types of data for an Object. Fields can be added to both custom and system Objects and can only store one type of data.

Liferay provides a user-friendly name for each field type, which corresponds to a specific data type in the back-end. When making Headless API calls that include fields, you must use the back-end data type names:

Field Types (UI)	Data Type (HEADLESS)	Description
Attachment	Relationship > Long	Stores jpeg, jpg, pdf, and png files no larger than 100 MB
Boolean	Boolean	Stores true or false values
Date	Date	Stores date values
Decimal (previously Double)	Double	Stores a decimal number value that supports fractional portions
Integer	Integer	Stores an integer up to 9 digits in length
Long Integer (previously Long)	Long	Stores a large integer up to 19 digits in length
Long Text (previously Clob)	Stores a text box value that supports up to 65,000 characters; when configuring this field type, you can limit the number of characters allowed
Picklist	String	Stores a Picklist string value
Precision Decimal (previously BigDecimal)	BigDecimal	Stores a high-precision decimal number without rounding
Relationship	Long	Stores the numeric ID for all related Object entries
Rich Text	Clob	Stores text with advanced formatting tools and media elements (e.g., images, videos, audio)
Text (previously String)	Stores simple text values up to 280 characters; when configuring this field type, you can limit the number of characters allowed
