oracle中trim函数和replace函数的用法
oracle中trim函数和replace函数的用法
For example:
trim(' tech ') would return 'tech'
trim(' ' from ' tech ') would return 'tech'
trim(leading '0' from '000123') would return '123'
trim(trailing '1' from 'Tech1') would return 'Tech'
trim(both '1' from '123Tech111') would return '23Tech'
--chr(10)是换行符，
--chr(13)是回车，
--replace(replace(tableSource,CHR(10),''),chr(13),'');
