Parameters

Parameter	Description	Supported input types

Examples

The following example trims the character x from both sides of a string:

SELECT BTRIM('xxThe Acceleration Cupxxx', 'x') as result

result (TEXT)
‘The Acceleration Cup’

The following example trims the characters x and y from both sides of a string. Note that the ordering of characters in <trim_characters> is irrelevant:

SELECT BTRIM('xyxyThe Acceleration Cupyyxx', 'xy') as result;

result (TEXT)
‘The Acceleration Cup’

The following example omits the parameter, and thus trims whitespace from both sides of a string:

SELECT BTRIM('   The Acceleration Cup     ') as result;

result (TEXT)
‘The Acceleration Cup’
