怎样才能去掉'tp'。从下面的字符串从它来的每个地方
str = " tp.FirstName, tp.FamilyName, tp.DOB, tp.TypeOfLocation
WHERE
tp.DateStamp BETWEEN '2012-02-12 15:13:00' AND '2013-02-12 15:13:00'
AND tp.db_name_id =21
AND
tp.FirstName = 'Darlene'";
我需要如下结果:
FirstName, FamilyName, DOB, TypeOfLocation
WHERE
DateStamp BETWEEN '2012-02-12 15:13:00' AND '2013-02-12 15:13:00'
AND db_name_id =21
AND
FirstName = 'Darlene'";
