What problem does this PR solve?

  • Add support for DATE, TIME, DATETIME and TIMESTAMP
  • Fix DESCRIBE table
  • Fix constant function output
  • Fix build scripts

Issue link: #371

What is changed and how it works?

Now we have initial support for DATE, TIME, DATETIME and TIMESTAMP

Representation in characters:

  • DATE should be represented in the format "YYYY-MM-DD" or "YYYY/MM/DD"
  • TIME should be represented in the format "HH:MM:SS"
  • DATETIME should be represented in the format DATE + " " + TIME
  • TIMESTAMP is the same as DATETIME

Supported sql query statements:

example 1:
  • CREATE TABLE date1selectwhere (i INTEGER, d1 DATE, d2 DATE);
  • DESCRIBE date1selectwhere;
  • INSERT INTO date1selectwhere VALUES (11, DATE '1870-11-1', DATE '2570-1-1');
  • INSERT INTO date1selectwhere VALUES (111, DATE '6570-11-1', DATE '5570-6-21');
  • SELECT * FROM date1selectwhere WHERE d1 < d2;
  • SELECT * FROM date1selectwhere WHERE d1 = DATE '1970-1-1' + INTERVAL -100 YEAR + INTERVAL 10 MONTH;
example 2:
  • CREATE TABLE datetimeselectwhere (t TIME, dt DATETIME, ts TIMESTAMP);
  • DESCRIBE datetimeselectwhere;
  • INSERT INTO datetimeselectwhere VALUES (TIME '12:0:0', DATETIME '5570-8-31 0:0:0', TIMESTAMP '6570-12-31 12:0:0');
  • SELECT EXTRACT('year' FROM ts + (INTERVAL 1 DAY)) FROM datetimeselectwhere WHERE EXTRACT('hour' FROM t) = 12;
