Change variable within SQL Server stored procedure

Question

I'm running a simple while loop that executes a stored procedure given a condition. Is there any way to access the stored procedure variable and change a variable within it before it executes? The variable I want to change is the same as the @date variable.

Thanks for any help guys.

declare @dayscount int
Declare @date as date

set @dayscount = 256
set @date = cast(GETDATE() - @dayscount as Date);

while (@dayscount >= 1)
   exec A

set @dayscount = @dayscount - 1

如果您所要做的只是在存储过程中递减或动态sql，并使用replace函数将变量替换为所需的值，然后在存储过程中运行execute_sql存储过程，则可以尝试在CTE中进行递归。
