# Properties

# arrayOid

• Readonly arrayOid: number

If typarray is not 0 then it identifies another row in pg_type, which is the array type having this type as element.

Inherited from: Type.arrayOid

Defined in: pg-structure/base/type.ts:53

# category

• category: TypeCategory

An arbitrary classification of PostgreSQL data types that is used by the PostgreSQL parser to determine which implicit casts should be “preferred”. See related doc here (opens new window)

Inherited from: Type.category

Defined in: pg-structure/base/type.ts:98

# classOid

• Readonly classOid: number

Object identifier of PostgreSQL class (pg_catalog.pg_class) for the Entity

Inherited from: Type.classOid

Defined in: pg-structure/base/type.ts:56

# comment

• Optional Readonly comment: undefined | string

Comment of the database object defined in database including {@link DbObject#commentData comment data}.

# Accessors

# commentData

Data which is extracted from database object's comment. Data is extracted from text between special case-insensitive tag (default: [pg-structure][/pg-structure]) and converted to JavaScript object using JSON5 (opens new window). Token name can be specified by using commentDataToken arguments. For details of JSON5 (opens new window), see it's web site: https://json5.org (opens new window).

# Example

// "Account details. [pg-structure]{ extraData: 2 }[/pg-structure] Also used for logging."
table.comment;               // "Account details. [pg-structure]{ extraData: 2 }[/pg-structure] Also used for logging."
table.commentWithoutData;    // "Account details.  Also used for logging."
table.commentData;           // { extraData: 2 }
table.commentData.extraData; // 2

Defined in: pg-structure/base/db-object.ts:102

# commentWithoutData

• get commentWithoutData(): undefined | string

Description or comment of the database object defined in database. If comment contains {@link DbObject#commentData comment data}, it is removed.

# Example

// "Account details. [pg-structure]{ extraData: 2 }[/pg-structure] Also used for logging."
table.commentWithoutData;    // "Account details.  Also used for logging."

Returns: undefined | string
