SQL截取字符串

select RIGHT(GZL,7),gzl FROM zxfqdhz

從右邊開始截取

select RIGHT( replace(replace(khjx,'-',''), '/',''),7),khjx FROM zxfqdhz

去除一些特殊字符

SELECT stuff('00000000',1,len(RIGHT( replace(replace(khjx,'-',''), '/',''),7) ),'')+CONVERT(varchar(50),RIGHT( replace(replace(khjx,'-',''), '/',''),7))  FROM zxfqdhz
