In this case we assuming that we’re selecting a string that we cast to a timestamp with TZ value. Date/Time ranges supported by Netezza. In fact the dates are treated as strings in Hive. See also CURRENT_TIMESTAMP. NuoDB provides functional support for date and time value processing. What is epoch time? The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). My favorite method is actually to use the Netezza supplied SQLToolkit and use a simple regular expression to only load a numeric. Run the following batch file (which assumes dd/mm/yyyy and hh:mm:ss) and modify the substring extraction (using the : and ~ characters) as required to get the proper parts from both Date and Time strings: For a live, published connection, NOW returns the data source server time. Let us learn about how to get Time in Hour:Minute Format from a Datetime as well as to get Date Part Only from Datetime. The unix_timestamp argument is an internal timestamp values, which are produced by the UNIX_TIMESTAMP() function. There is DATE and there is TIMESTAMP however presently we don’t have any explicit TIME data type in HIVE. Actually: The Timestamp datatype could also contain fractional seconds. Some of the more commonly used date functions extract the day of the week, the month, or the year from a SAS date value. Any columns using these types are read into SAS as character strings. If the format is given, the result is formatted according to the format string, which is used in the same way as is listed in the entry for the DATE_FORMAT() function. Date/time/timstamp columns can also be mapped to bigint Hive type in which case the value will be the number of milliseconds since epoch. Developers do not have access to the Netezza machine so can you tell me how to do little things like tell if a table has stats on it and when the were last refreshed. The difference between this function and CURRENT_TIMESTAMP is that LOCALTIMESTAMP returns a TIMESTAMP value while CURRENT_TIMESTAMP returns a TIMESTAMP WITH TIME ZONE value When using TO_DATE function in Netezza, please make a note that TO_DATE function does not return (or rather consider) the TIME portion of it. Netezza Vs Oracle Function Comparision. When extracting from a datetime with a time zone value, the value returned is in UTC. The PostgreSQL timestamp is a date time format (for those coming from SQL Server and MySQL) and of course is much richer than Unix Timestamp. These data types are likely applicable to both 5. Date and time values IBM® Netezza ® SQL does not SELECT EXTRACT(DAY FROM TIMESTAMP '2007-02 Not all units can be used to extract values from a particular temporal data type. returns time. CURRENT_TIME[(precision)] Return current time - will return the same value for all invocations in the user command. Therefore, the unix time stamp is merely the number of seconds between a particular date and the Unix Epoch. (the full date/time/timestamp representation). I have seen scores of expert developers getting perplexed with SQL Server in finding time only from datetime datatype. These are reserved words that the system will deliver to you when requested. A common activity with any database or programming language is interacting with dates and times. The purpose of the Oracle TO_TIMESTAMP function is to convert a string value into a timestamp value. Date instance. It always displays such a value in the local time zone, not as entered. For example, if the local time zone was +4:00 at the time of the given Unix timestamp, the returned value is local timestamp at the time with time zone +4:00. x. It looks like to me like TO_DATE can't resolve the milliseconds correctly. The Date and Time format depends on what you've specified in the Region and Language Control Panel applet. SAS Date or Datetime format Tutorial How to Convert integers to Date/datetime in SAS/Netezza?

EXTRACT(field from timestamp), EXTRACT(field from interval) The EXTRACT(field FROM source) function retrieves subfields such as year or hour from date/time values. Converting to and from Epoch Time. After running the Assessment Tool, the extracted script needs to be copied to the Netezza system/appliance (or a machine with the Netezza client binaries) and executed. My example showed that our next last_checked timestamp is noted at the *beginning* of the query's transaction, not the end. Additionally, Phoenix supports the ANSI SQL timestamp literal which acts similarly to the single-argument TO_TIMESTAMP function. It's purpose is to help automate the extraction of the Netezza database schemas. The table below illustrates this functionality. The time zone of the returned value is the local time zone at the time of the timestamp argument. 2) Most important for Netezza is distribution of data on SPU or disk. All number types. Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for 'Unix time'. Note that PostgreSQL's time with time zone type is implemented differently. When you extract a TIMEZONE_REGION or TIMEZONE_ABBR (abbreviation), the value returned is a string containing the appropriate time zone name or abbreviation. Note that this is generated by "SQuirrel" tool using Netezza JDBC. Seems there is a built-in function housed in the pg_catalog schema that allows for very quick parsing.
