I have following table structure, for convenience purpose I am only marking individual columns
Table_A
(Id, Name, Desc
)Table_1
(Id
this is identity column, Name
....)Table_2
(Id
this is identity column, Table_A_Id
, Table_1_Id
)The relationship between Table_1 and Table_2 is 1...*
Now I have created a table type for Table_A
called TType_Table_A
(which only contains Id
as column and from my C# app I send multiple records). I have achieved this bulk insert functionality as desired.
What I need is when I insert records into Table_2
from TType_Table_A
say with below statements, I would like to capture the Id
of Table_2
for each record inserted
declare @count int = (select count(*) from @TType_Table_A); --a variable declared for TType_Table_A
if(@count > 0)
begin
insert into Table_2(Table_A_Id,Table_1_Id)
SELECT @SomeValue, @SomeValueAsParameter FROM @TType_Table_A;
end;
Now say if 2 records are inserted, I would like to capture the Id
for each of these 2 records.
Any input/help is appreciated
This is what I know how it can be achieved, but I want to reduce DB calls from my app or user cursor in stored procedure
Insert record in Table_1 and return back the Id Loop.....through records and insert record in Table_2 and return back the Id
OR
Use cursor in stored procedure when inserting/selecting from TableType
I assume this is Sql Server? Then you can make use of the OUTPUT clause, like so:
declare @NewId table (MyNewId INT)
insert into Table_2(Table_A_Id,Table_1_Id)
output inserted.MyNewId INTO @NewId (MyNewID)
SELECT SomeValue, SomeValueAsParameter FROM @TType_Table_A;
SELECT * FROM @NewId
