Character data types

Character data types are used to store strings of letters, numbers, and other symbols.

SQL Anywhere provides two classes of character data types and some domains defined using those types.

  • CHAR, VARCHAR, LONG VARCHAR   Character data stored in a single- or multibyte character set, often chosen to correspond most closely to the primary language or languages stored in the database.

  • NCHAR, NVARCHAR, LONG NVARCHAR   Character data stored in the UTF-8 Unicode encoding. All Unicode code points can be stored using these types, regardless of the primary language or languages stored in the database.

  • TEXT, UNIQUEIDENTIFIERSTR, XML   Domains based on other character data types.
