ASTERIXDB-1539: add aliases for several builtin types and builtin functions. - tinyint for int8; - smallint for int16; - integer(or, int) for int32; - bigint for int64; - year_month_duration for year-month-duration; - day_time_duration for day-time-duration; - timestamp for datetime; - double precision for double;
int8, int16, int32, int64, year-month-duration and day-time-duration is going to be deprecated.
In addition, it - converts underscores to hypens for SQL++ functions; - uses "array_" prefix for builtin aggregation functions.
Use backticks instead of double quotes for delimited identifiers in SQL++.
