Mysql 怎么去掉小数点后多余的0

写个函数 自己调用处理就行了CREATE FUNCTION `NewProc`(format_vale VARCHAR(100)) RETURNS varchar(100)BEGINDECLARE dec_number VARCHAR(4000) DECLARE dec_number_vale VARCHAR(4000) SET dec_number = '' SET dec_number_vale = CAST(format_vale AS CHAR) WHILE dec_number_vale IS NOT NULL DO -- 剪切字符串SET dec_number = right(dec_number_vale,1) IF dec_number = '0' || dec_number= '.' THEN SET dec_number_vale = LEFT(dec_number_vale ,LENGTH(dec_number_vale)-1) ELSERETURN dec_number_vale END IF END WHILEEND

DECLARE @i INT DECLARE @n INT DECLARE @t VARCHAR(20) SET @t='' SET @i=0 SELECT @n=len(sr1) FROM ts_2 --PRINT @n WHILE @i
