DateParse
The DateParse function parses a text string representing a date in the specified format and returns the equivalent ISO datetime value (YYYY-MM-DD HH:MM:SS).
If the input is a text or number value that reflects ISO (
YYYY-MM-DDorYYYY-MM-DD HH:MM:SS) or Unix time format, you can use the Date function, which doesn't require you to specify the input format.
Syntax
DateParse(text, format)
Function arguments
| text | (required) The text string or column of text strings to parse. |
| format | (required) The datetime format of the text string. |
Compatible format specifiers
The DateParse function uses the datetime formatting functionality of the connected CDW or DBMS. The following format specifiers are supported by most connections and can be used to build the datetime format string.
BigQuery doesn't support the %L and %f specifiers.
| Format | Description | Example output (for 2018-07-08 00:34:59) |
|---|---|---|
| %Y | Four-digit year | 2018 |
| %y | Two-digit year | 18 |
| %m | Two-digit month | 07 |
| %B | Full month name | July |
| %b | Abbreviated month name | Jul |
| %A | Full day of week | Sunday |
| %a | Abbreviated day of week | Sun |
| %d | Two-digit day of month (01-31) | 08 |
| %H | Two-digit hour based on 24-hour clock (00–23) | 00 |
| %I | Two-digit hour based on 12-hour clock (01–12) | 12 |
| %M | Two-digit minutes (00–59) | 34 |
| %S | Two-digit seconds (00–59) | 59 |
| %p | AM or PM | AM |
| %L | Three-digit milliseconds (000–999) | 000 |
| %f | Six-digit microseconds (000000–999999) | 000000 |
| %Z | Time zone offset | -07:00 |
| %% | Percent symbol | % |
Because two-digit years converted with the
%yconversion are ambiguous, dates with a%yof 00–69 convert to 2000–2069 and dates with a%yof 70–99 convert to 1970–1999.
Examples
Example 1
DateParse("03-Sep-2020:03:05:13", "%d-%b-%Y:%H:%M:%S")

Example 2
DateParse([Text Date], "%d/%b/%Y:%H:%M:%S")
Parses text strings in the Text Date column using the specified format (%d/%b/%Y:%H:%M:%S) and returns equivalent values in ISO datetime format.
Example 3
