Question

I have a Winform that has fields need to be filled by a user. All the fields doesn’t belong to one table, the data will go to Customer table and CustomerPhone table, so i decided to do multiple inserts. I will insert appropriate data to CustomerPhone first then Insert the rest data to Customer table.

Is it possible to Join an Insert OR Insert a Join? If show me a rough sample, i will be grateful.

Many Thanks

Strictly speaking, you can chain inserts and updates in a single statement using the OUTPUT clause. For example, the code bellow inserts at once into two distinct tables:

create table A (
    id_a int not null identity(1,1) primary key,
    name varchar(100))
create table B (
    id_b int not null identity(1,1) primary key,
    id_a int null,
    name_hash varbinary(16));

insert into A (name)
output inserted.id_a, hashbytes('MD5', inserted.name)
into B (id_a, name_hash)
values ('Jonathan Doe')

select * from A
select * from B
