Date literals are formatted
YYYY.MM.DD
or alternatively
{^YYYY-MM-DD}
DateTime Literals can be constructed with the followin syntax:
{^YYYY-MM-DD HH:MM:SS}.
Examples:
2000.01.01
2012.02.29
2015.09.25
// foxpro date and datetime literals
{^2019.02.28}
{^2020.02.29 23:59:59}
Date and DateTime literals are supported in all dialects. In the Core dialect, both date and datetime literals will be translated to a DateTime value. In the other dialects, the Date literals are translated to a Date value.
Of course you can also use runtime functions to construct a literal, such as STOD("20150925") or ConDate(2019,9,25), but a literal is more efficient.
