存储过程选择变量

Question

如何计算表的结果并传入存储过程变量？

DECLARE @totalrecs varchar
select count(id) from table1

我想在totalrecs变量中记录计数记录。

Answer 1

像这样

--will not count NULLS
select @totalrecs= count(id) from table1

--will count NULLS
select @totalrecs= count(*) from table1

Answer 2

DECLARE @totalCount Int
Select @totalCount = count(*) 
From table1

Exec sp_DoSomething @Var = @totalCount

Answer 3

select @totalrecs= count(id) from table1
