字符串转换成日期出错啦！

[firefox_1983]

declare @datestr varchar(10)
set @datestr='2006-1-24'
select * from ccdd where dt between convert(datetime,@datestr+'00:00:00',120 ) and convert(datetime,@datestr+'23:59:59',120)
从字符串转换为 datetime 时发生语法错误。怎么修改?

[lsqkeke]

select * from ccdd where dt between convert(datetime,@datestr+' 00:00:00',120 ) and convert(datetime,@datestr+' 23:59:59',120)

注意空格

--中间少了空格
declare @datestr varchar(10)
set @datestr='2006-1-24'
select * from ccdd where dt between convert(datetime,@datestr+' 00:00:00',120 ) and convert(datetime,@datestr+' 23:59:59',120)

[子陌红尘]

declare @datestr varchar(10)
set @datestr='2006-1-24'
select * from ccdd where dt between convert(datetime,@datestr+' 00:00:00',120 ) and convert(datetime,@datestr+' 23:59:59',120)

或者：
select * from ccdd where dt between cast(@datestr+' 00:00:00' as datetime ) and cast(@datestr+' 23:59:59' as datetime)
