Go Up to Specifying Data Types
InterBase supports four character string data types:
- A fixed-length character data type, called
CHAR
(<n>) orCHARACTER
(<n>), where <n> is the exact number of characters stored. - A variable-length character type, called
VARCHAR
(<n>) orCHARACTER
VARYING
(<n>), where <n> is the maximum number of characters in the string. - An
NCHAR
(<n>) orNATIONAL CHARACTER
(<n>) orNATIONAL CHAR
(<n>) data type, which is a fixed-length character string of <n> characters which uses the ISO8859_1 character set. - An
NCHAR VARYING
(<n>) orNATIONAL CHARACTER VARYING
(<n>) orNATIONAL CHAR VARYING
(<n>) data type, which is a variable-length national character string up to a maximum of <n> characters.
