I have three tables (Country table, state table and City table. Country table is primary key(Id) table and State table is foreign key(C-Id) and City table is foreign key(Sid) table. So my problem is when i insert data in table value of id column should come from Font-end application. using the id i retrieve and insert the values with newid()
Table design follow as,
Country State City
-------- --------- -------------
Id --> PK ID ---> PK ID ---> PK
Name Name Name
C-ID --> foreign key(Countrytable) S-ID --> FK(State)
Values in Table
1. Country
ID Name
------------------------------- ----------
1AA7C63A5F532041BAE588E407A167E3 India
2. State
ID Name C-ID
------------------------------- ------- -------------
AF2A025C13CB4C4994CC4A3461234146 State1 1AA7C63A5F532041BAE588E407A167E3
CC78FD8E01883F429F8A960DC7AD41A0 State2 1AA7C63A5F532041BAE588E407A167E3
3. City
ID Name S-ID
------------------------------- ------- -------------
9F968DA0448E4F7FA87C4AED6D87CD54 City1 AF2A025C13CB4C4994CC4A3461234146
B5F341B342D04CEEBD19B01FD9D2EBF7 City2 AF2A025C13CB4C4994CC4A3461234146
844EFE0127C04840BBFDB64CED54C788 City3 CC78FD8E01883F429F8A960DC7AD41A0
1D4016CF328E447B89764638BBD7EC21 City4 CC78FD8E01883F429F8A960DC7AD41A0
ALTER PROCEDURE [dbo].[c_Copy_Country_C]
-- Add the parameters for the stored procedure here
@FrontEnd-Id varchar(36) = NULL
AS
SET XACT_ABORT ON
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON;
--
DECLARE @TransactionName varchar(20)
Set @TransactionName = 'TransCountry'
--Begin Transaction
BEGIN TRAN @TransactionName
--------------------Begin copy----------------------------------------
--- Insert new dbo.Country_C record -------------------------------
Declare @IdNew varchar(36)
Set @IdNew = Replace(CONVERT(varchar(255), NewID()),'-','')
Insert Into dbo.Country_C with (ROWLOCK)
Select @IdNew,Name from dbo.Country_C with (NOLOCK) where Id = @Frontend-Id
-- Insert all dbo.Country_c records-------------------------
Insert Into dbo.State_C with (ROWLOCK)
Select Replace(CONVERT(varchar(255), NewID()),'-',''),Name,@IdNew from dbo.State_C with (NOLOCK) where Id = @Frontend-Id
-- Insert all dbo._City_c records-------------------------
Insert Into dbo.City_C with (ROWLOCK)
Select Replace(CONVERT(varchar(255), NewID()),'-',''),Name,Replace(CONVERT(varchar(255), NewID()),'-','') from dbo.City_C with (NOLOCK) where S-Id in (Select id from dbo.State_C where C-ID = @Frontend-Id )
IF @@ERROR <> 0
BEGIN
-- Return 0 to the calling program to indicate failure.
ROLLBACK TRAN @TransactionName
Select 0 as ReturnState;
END
ELSE
BEGIN
-- Return 1 to the calling program to indicate success.
COMMIT TRAN @TransactionName
Select 1 as ReturnState;
END
END
In Front end application i execute the procedure
Exec [Procedurename] 'Frontend-id'
Now I need to insert only the name into the three tables with CountryName, StateName and CityName.with create a new IDs.
The problem is , Country and state data values inserting.
City return multiple values , so that the City names missing.
How to Solve, and please correct the llines..
Many Thanks |

when you insert data to Cities you wont be having any data for current S-id value right, then how will that IN condition ever return any records?

i think what you need is to use OUTPUT clause to capture the currently inserted state id and then use it for the insertion logic to City table.
I dont know from where you get values for Name etc fields to be inserted to City table

doesnt look to have any issues. only probability is S-ID having some unprintable characters in State table (spaces etc)
Whats the datatype of id in State table?
