# String types

The string type is declared with the keyword `STRING` and is used to store a sequence of characters.

## Length limits

GQL imposes different length limits on strings depending on the context:

- Property strings: Strings stored as node or edge properties are limited to 65,535 bytes.
- Runtime strings: Strings in runtime contexts, such as expression evaluation and function return values, are limited to 2³²−1 bytes (approximately 4 GB).

Strings must be enclosed in single quotes (`'`) or double quotes (`"`).

## Declaration example

````
'''
CREATE GRAPH TYPE IF NOT EXISTS person AS  
    { NODE Person 
        ( { 
            id INT64 PRIMARY KEY,  
            is_adult BOOL DEFAULT TRUE,  
            name STRING DEFAULT 'John Doe',  
            hobbies LIST<STRING> DEFAULT ['reading', 'swimming'], 
            birthday DATE DEFAULT DATE('1990-01-01') 
        } ) 
    }
'''

````

In the preceding example, the property `name` is of the string type (`STRING`) with a default value of `John Doe`.
