是否可以在TSQL存储过程中包含一组"常量"值？我有一种情况,我使用整数字段来存储位值,我有一小组"常量"值,我用来插入/选择该字段

DECLARE @CostsCalculated int = 32
DECLARE @AggregatedCalculated int = 64

--Set CostCalculated bit
update MyTable set DataStatus = ISNULL(DataStatus, 0) | @CostsCalculated
where Id = 10

--How many rows have that bit set
select count(*) from MyTable where ISNULL(DataStatus, 0) & @CostsCalculated = @CostsCalculated

我可以在每个SP的顶部重复相同的DECLARES集,但我宁愿包含代码,这意味着我可以在添加新位值时在一个地方进行更改.
