I cant find the difference between the date/time types, arent all of them the same? also should I parse them as int or string? TIME Type TIME
The time data type. The format is yyyy-MM-dd hh:mm:ss, with both the date and time parts maintained. Mapped to java.sql.Time. The binary representation is an 8 byte long (the number of milliseconds from the epoch), making it possible (although not necessarily recommended) to store more information within a TIME column than what is provided by java.sql.Time. Note that the internal representation is based on a number of milliseconds since the epoch (which is based on a time in GMT), while java.sql.Time will format times based on the client's local time zone. Please note that this TIME type is different than the TIME type as defined by the SQL 92 standard in that it includes year, month, and day components. As such, it is not in compliance with the JDBC APIs. As the underlying data is still stored as a long, only the presentation of the value is incorrect. Example: TIME DATE Type DATE The date data type. The format is yyyy-MM-dd hh:mm:ss, with both the date and time parts maintained to a millisecond accuracy. Mapped to java.sql.Date. The binary representation is an 8 byte long (the number of milliseconds from the epoch), making it possible (although not necessarily recommended) to store more information within a DATE column than what is provided by java.sql.Date. Note that the internal representation is based on a number of milliseconds since the epoch (which is based on a time in GMT), while java.sql.Date will format dates based on the client's local time zone. Please note that this DATE type is different than the DATE type as defined by the SQL 92 standard in that it includes a time component. As such, it is not in compliance with the JDBC APIs. As the underlying data is still stored as a long, only the presentation of the value is incorrect. Example: DATE TIMESTAMP Type TIMESTAMP The timestamp data type. The format is yyyy-MM-dd hh:mm:ss[.nnnnnnnnn]. Mapped to java.sql.Timestamp with an internal representation of the number of nanos from the epoch. The binary representation is 12 bytes: an 8 byte long for the epoch time plus a 4 byte integer for the nanos. Note that the internal representation is based on a number of milliseconds since the epoch (which is based on a time in GMT), while java.sql.Timestamp will format timestamps based on the client's local time zone. Example: TIMESTAMP UNSIGNED_TIME Type UNSIGNED_TIME The unsigned time data type. The format is yyyy-MM-dd hh:mm:ss, with both the date and time parts maintained to the millisecond accuracy. Mapped to java.sql.Time. The binary representation is an 8 byte long (the number of milliseconds from the epoch) matching the HBase.toBytes(long) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead. Example: UNSIGNED_TIME UNSIGNED_DATE Type UNSIGNED_DATE The unsigned date data type. The format is yyyy-MM-dd hh:mm:ss, with both the date and time parts maintained to a millisecond accuracy. Mapped to java.sql.Date. The binary representation is an 8 byte long (the number of milliseconds from the epoch) matching the HBase.toBytes(long) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead. Example: UNSIGNED_DATE UNSIGNED_TIMESTAMP Type UNSIGNED_TIMESTAMP The timestamp data type. The format is yyyy-MM-dd hh:mm:ss[.nnnnnnnnn]. Mapped to java.sql.Timestamp with an internal representation of the number of nanos from the epoch. The binary representation is 12 bytes: an 8 byte long for the epoch time plus a 4 byte integer for the nanos with the long serialized through the HBase.toBytes(long) method. The purpose of this type is to map to existing HBase data that was serialized using this HBase utility method. If that is not the case, use the regular signed type instead. Example: UNSIGNED_TIMESTAMP
