postgresqlHow do I use the PostgreSQL to_char function?
to_char function is used to convert a timestamp or number into a string. The syntax of the
to_char function is as follows:
value is the timestamp or number to be converted and
format is the format to use for the conversion.
For example, to convert a timestamp to a string with the format of 'DD-MON-YYYY' you would use the following:
SELECT to_char(current_timestamp, 'DD-MON-YYYY');
Which would output something like:
format argument can contain a wide variety of elements, including:
YYYY: 4-digit year
MM: 2-digit month
DD: 2-digit day
HH24: 24-hour format
For a full list of available elements, see the PostgreSQL documentation.
to_char function is very useful when working with timestamps and numbers, allowing them to be easily converted into strings for display or other purposes.
