It returns an error: ERROR: date/time field value out of range: " 30:8:00" TO_TIMESTAMP( ' 30:8:00', 'YYYY-MM-DD HH24:MI:SS') Code language: JavaScript ( javascript ) The following example uses an invalid timestamp value: SELECT It will try to convert the input string to a valid timestamp as much as possible that sometimes yields unexpected results. SQL state: 22007 Code language: Shell Session ( shell )īecause the FX option instructs the TO_TIMESTAMP() to accept the input string with one space only.Ģ) The TO_TIMESTAMP() function validates the input string with minimal error checking. Output: ERROR: invalid value "" for "MON"ĭETAIL: The given value did not match any of the allowed values for this field. TO_TIMESTAMP( '2017 Aug', 'FXYYYY MON') Code language: JavaScript ( javascript ) However, the following example returns an error: SELECT The TO_TIMESTAMP() function just omits the spaces and returns the correct timestamp value: to_timestamp.

Month in lowercase Roman numerals (i-xii > Month in upper case Roman numerals (I-XII > Julian Day (integer days since NovemBC at midnight UTC) Week number of ISO 8601 week-numbering year (01-53 the first Thursday of the year is in week 1) Week number of year (1-53) (the first week starts on the first day of the year) Week of month (1-5) (the first week starts on the first day of the month) ISO 8601 day of the week, Monday (1) to Sunday (7) Last digit of ISO 8601 week-numbering yearĪbbreviated uppercase month name e.g., JAN, FEB, etc.Ībbreviated capitalized month name e.g, Jan, Feb, etc.Ībbreviated lowercase month name e.g., jan, feb, etc.ĭay of ISO 8601 week-numbering year (001-371 day 1 of the year is Monday of the first ISO week)ĭay of the week, Sunday (1) to Saturday (7) Last 2 digits of ISO 8601 week-numbering year Last 3 digits of ISO 8601 week-numbering year ISO 8601 week-numbering year (4 or more digits) To construct format strings, you use the following template patterns for formatting date and time values.
