How do DATETIME values work in SQLite?

Question

I’m creating Android apps and need to save date/time of the creation record. The SQLite docs say, however, \"SQLite does not have a storage class set aside for storing dates

Answer 1

One of the powerful features of SQLite is allowing you to choose the storage type. Advantages/disadvantages of each of the three different possibilites:

• ISO8601 string

  • String comparison gives valid results
  • Stores fraction seconds, up to three decimal digits
  • Needs more storage space
  • You will directly see its value when using a database browser
  • Need for parsing for other uses
  • "default current_timestamp" column modifier will store using this format

• Real number

  • High precision regarding fraction seconds
  • Longest time range

• Integer number

  • Lowest storage space
  • Quick operations
  • Small time range
  • Possible year 2038 problem

If you need to compare different types or export to an external application, you're free to use SQLite's own datetime conversion functions as needed.
