The SQL function trim(leading from …) removes space characters from the begin (left side) of a string.

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

The result of the example is the text 'traveling space   ' with the leading spaces removed.

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