Question

为什么会显示错误？

declare @start_date date, @end_date date

set @start_date = '2018-06-01'
set @end_date = '2018-11-30' 
go

select * 
into mytable_TB 
from Other_Table 
where mis_date >= @start_date 
  and mis_date <= @end/_date

错误：

必须声明标量变量@start_date

有人知道原因吗？

消除了在变量声明和选择查询之间的转入，因此，GO是一个批处理分隔符，用于将整个脚本分成批处理

declare @start_date date, @end_date date

set @start_date = '2018-06-01'
set @end_date = '2018-11-30' 


select * into mytable_TB from Other_Table where mis_date >= @start_date 
and mis_date <= @end_date

声明变量并插入临时表
