parseDate

parseDate parses a string to determine if it contains a date value, and returns a standard date in the format yyyy-MM-ddTkk:mm:ss.SSSZ (using the format pattern syntax specified in Class DateTimeFormat in the Joda project documentation), for example 2015-10-15T19:11:51.003Z. This function returns all rows that contain a date in a valid format and skips any rows that don't, including rows that contain null values.

Amazon QuickSight supports dates in the range from Jan 1, 1900 00:00:00 UTC to Dec 31, 2037 23:59:59 UTC. See also Supported Date Formats.

Note

parseDate is not supported for use with SPICE data sets.

Syntax

parseDate(expression, ['format'], ['time_zone'])

Arguments

expression

The expression must be a string. It can be the name of a field that uses the string data type, a literal value like '1/1/2016', or a call to another function that outputs a string.

format

(Optional) A string containing the format pattern that date_string must match. For example, if you are using a field with data like 01/03/2016, you specify the format 'MM/dd/yyyy'. If you don't specify a format, it defaults to yyyy-MM-dd. Rows whose data doesn't conform to format are skipped.

Different date formats are supported based on the type of data set used. Use the following table to see details of supported date formats.

Example

The following example evaluates Field2 to determine if it contains date values.

parseDate(Field2, 'MM/dd/yyyy')

The following are the given field values.

Field2 -------- 01-01-1999 12/31/2006 1/18/1982 7/4/2010

For these field values, the following rows are returned.

12-31-2006T00:00:00.000Z 01-18-1982T00:00:00.000Z 07-04-2010T00:00:00.000Z
