The TO_TIMESTAMP function is useful when dealing with timestamp values stored as strings or when importing data from external sources with timestamp information in non-standard formats. If the timestamp string and format do not align correctly, PostgreSQL will raise an error. It’s important to ensure that the timestamp_string matches the format specified in the TO_TIMESTAMP function. HH24: Two-digit hour in 24-hour format (00 to 23).įor instance, if the timestamp string is in the format ‘DD-MM-YYYY HH:MI:SS’, you would use the following TO_TIMESTAMP statement: SELECT TO_TIMESTAMP('06-08-2023 15:30:45', 'DD-MM-YYYY HH:MI:SS') AS converted_timestamp The format pattern consists of special placeholders that represent the parts of the timestampĭD: Two-digit day of the month (01 to 31). This query will return 15:30:45 as a timestamp data type, assuming the timestamp string ‘ 15:30:45’ is in the format ‘YYYY-MM-DD HH24:MI:SS’. Where timestamp_string is the string representing the timestamp that you want to convert,Īnd format is the format pattern that matches the structure of the timestamp_string.īelow is an example of using the TO_TIMESTAMP function to convert a timestamp string into a timestamp: SELECT TO_TIMESTAMP(' 15:30:45', 'YYYY-MM-DD HH24:MI:SS') AS converted_timestamp The basic syntax of the TO_TIMESTAMP function is as follows: TO_TIMESTAMP(timestamp_string, format) It allows you to parse timestamp strings in a specific format and convert them into valid timestamp values that can be stored or used for date and time-related operations. In PostgreSQL, the TO_TIMESTAMP function is used to convert a string representation of a timestamp into a timestamp data type.
