Literal Collection
Use the Literal Collection segment to specify values for a collection data type. For the syntax of expressions that return values of individual elements within a collection, see Collection Constructors.
Syntax
Usage
You can specify literal collection values for SET, MULTISET, or LIST data types.
To
specify a single literal-collection value, specify the collection
type and the literal values. The following SQL statement
inserts four integer values into a column called set_col that
was declared as
SET(INT NOT NULL)
: INSERT INTO table1 (set_col) VALUES (SET{6, 9, 9, 4});
Specify
an empty collection with an empty pair of braces ( { } ) symbols.
This example inserts an empty list into a column list_col that
was declared as
LIST(INT NOT NULL):
INSERT INTO table2 (list_col) VALUES ('LIST{}');
A pair of single ( ' ) or double ( " ) quotation marks can delimit the collection. Double quotation marks are not valid, however, in databases where delimited identifiers are enabled, except to delimit SQL identifiers.
If you are passing a literal collection as an argument to an SPL routine, make sure that there is a blank space between the parentheses that surround the arguments and quotation marks that indicate the beginning and end of the literal collection.
