Search conditions that compare dates

You can use operators other than equals to select a set of rows that satisfy the search condition. The inequality operators (< and >) can be used to compare numbers, dates, and even character strings.

Notes

Automatic conversion to dates The SQL Anywhere database server knows that the BirthDate column contains dates, and automatically converts the string 'March 13, 1964' to a date.
Ways of specifying dates There are many ways of specifying dates. For example:
'March 13, 1964' '1964/03/13' '1964-03-13'
You can configure the interpretation of dates in queries by setting the date_order option database option.

Dates in the format yyyy/mm/dd or yyyy-mm-dd are always recognized unambiguously as dates, regardless of the date_order setting.
Other comparison operators SQL Anywhere supports several comparison operators.
