SQL Server DELETE中更好的性能

Question

I'm trying to delete specific rows from various tables by id in my database, and I have too many tables to delete from, for example:

DELETE FROM [Customers] 
WHERE [id] = @Id

DELETE FROM [Agents]
WHERE [id] = @Id

DELETE FROM [Policy] 
WHERE [id] = @Id

DELETE FROM [Issues]
WHERE [id] = @id

DELETE FROM [Refunds] 
WHERE [id] = @Id

EXEC SP_DeleteCustomerRelations @Id
EXEC SP_DeleteAgentComplaints @Id

DELETE FROM [dbo].[Complaints]
WHERE id = @Id

I was wondering if there anyway to enhance the performance of this SQL query?

Or is there anyway to not repeat DELETE? As it takes up to 10 seconds deleting from all these rows from tables.

Answer 1

Are these Tables in relation of parent/child means is that ID is PK of one table and used as a FK in the other ones. If it is the scenerio you can use the cascading here means when ID is deleted from the parent table it will automatically get deleted from the child tables. See this link for How to use Cascade Delete .

Hope this helps please let me know if it doesnt helps.
