SQL
Text Type Values
Values of the text type are character strings, also known as string values or simply strings. At runtime, string values are constructed in one of the following ways:  
* referencing columns whose declared or implied type is the text data type
* [string literals](#docs:sql:data_types:literal_types::string-literals)
* [casting](#docs:sql:expressions:cast::explicit-casting) expressions to a text type
* applying a [string operator](#docs:sql:functions:char::text-functions-and-operators), or invoking a function that returns a text type value
