The SQL function trim(both from …) removes space characters from the end (right side) of a string. The keywords both from are optional.

SELECT TRIM(BOTH FROM '   traveling spaces   ')
  FROM …

The result of the example is the text 'traveling space' with the spaces removed from both ends.

The trim() function, including the both from keywords, is defined in ISO/IEC 9075:2016-2 as mandatory feature E021-09.
