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.

Insights supports dates in the range from Jan 1, 1900 00:00:00 UTC to Dec 31, 2037 23:59:59 UTC. For more information, see Supported date formats.

Syntax

Copy

parseDate(expression, ['format'])

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 dataset used. Use the following table to see details of supported date formats.
