如何去掉mysql中小数多余的0

写个函数 自己调用处理就行了

CREATE FUNCTION `NewProc`(format_vale VARCHAR(100))

RETURNS varchar(100)

BEGIN

DECLARE 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)

ELSE

RETURN dec_number_vale

END IF

END WHILE

END

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
