Sql中补零方法及其它

select right ('00000'+XKZID,5) as XKZID from WXTemplicence 原来是 1 ,2,3......10,11 现在是 00001,00002,00003.......00010,00011.不够五位的, 左边补零

select left (XKZID+'00000',5) as XKZID from WXTemplicence 原来是 1 ,2,3......10,11 现在是10000,20000,30000.......10000,11000.不够五位的, 右边补零

select cast(yuangongbh as int) from jxyuangongxx where jiaxiaobh='6101045003' 把原来是字符型的转化为整型，去掉前面的 “0”，如“0013”变为“13”
