Literal Row

The Literal Row segment specifies the syntax for literal values of named and unnamed ROW data types.

For expressions that evaluate to field values within a ROW data type, see ROW constructors.

Syntax

Literal Row

Field Literal Value

Notes:


Element	Description	Restrictions	Syntax
literal_opaque_type	Literal representation for an opaque data type	Must be a literal that is recognized by the input support function for the associated opaque data type	Defined by the developer of the opaque data type
literal_BOOLEAN	Literal representation of a BOOLEAN value	Must be either `'t'` (= TRUE) or `'f'` (= FALSE) specified as a quoted string	Quoted String

Usage

You can specify literal values for named ROW and unnamed ROW data types. A ROW constructor introduces a literal ROW value, which can optionally be enclosed between quotation marks.

The format of the value for each field of the ROW type must be compatible with the data type of the corresponding field.

Important: You cannot specify simple-large-object data types (BYTE or TEXT) as the field type for a row.

Fields of a row can be literal values for the data types in the following table.


For a Field of Type	Literal Value Syntax
BOOLEAN	`t` or `f`, representing TRUE or FALSE
CHAR, VARCHAR, LVARCHAR, NCHAR, NVARCHAR, CHARACTER VARYING, DATE	Quoted String
DATETIME	Literal DATETIME
BIGINT, DECIMAL, MONEY, FLOAT, INTEGER, INT8, SMALLFLOAT, SMALLINT	Literal Number
INTERVAL	Literal INTERVAL
Opaque data types	Quoted String The string must be a literal that is recognized by the input support function for the associated opaque type.
Collection type (SET, MULTISET, LIST)	Literal Collection For information on literal collection values as variable or column values, see Nested Quotation Marks. For information on literal collection values for a ROW type, see Literals for Nested Rows.
Another ROW type (named or unnamed)	For information on ROW type values, see Literals for Nested Rows.
