Declares a date value in ANSI DATE format in an expression.

ANSI DATE literal is the preferred format for date constants. All date operations accept this format.

DATE 'string'

string

A 10-character string enclosed in apostrophes in the following form:

YYYY-MM-DD

YYYY represents year. The valid range is 0001 through 9999, inclusive. You must specify all four digits.
MM represents month. The valid range is 01 through 12, inclusive. You must specify both digits.
DD represents day. The valid range is 01 through 31, inclusive, constrained by Gregorian calendar definitions. You must specify both digits.

Date literals consist of the word DATE followed by a character string literal. This character string specifies the date value.

The year, month, and day components of the string literal must be separated by hyphens.

Spaces and new line characters are not allowed in a literal except after the keyword DATE.

DATE

The following example selects all classes from the Classes table that start on January 6, 1998.

SELECT *
FROM CLASSES
WHERE startdate = DATE '1998-01-06';
