一个简单的sql语句拼接问题
sql 2005 环境

declare @sql varchar(1000)
declare @startHH int
declare @endHH int
set @startHH = 1
set @endHH = 2
set @sql = ''
print @startHH
print @endHH
Select @sql = @sql + ' and datepart(hh, ATable.insertTime) between '+''''+ @startHH + '''' + ' and ' +''''+ @endHH + ''''

执行报错，从varchar转换成int时失败，怎么修改？
哎，每次遇到拼接字符串和变量就会出错，郁闷 SQL 字符串拼接
[解决办法]
Select @sql = @sql + ' and datepart(hh, ATable.insertTime) between '+''''+ convert(nvarchar(20),@startHH) + '''' + ' and ' +''''+ convert(nvarchar(20),@endHH) + ''''
