Insert query as string in database on insert trigger - sql-server

Question

I am trying to create a trigger that will fire every time a new row is created in a table. When that happens, an insert query will be prepared that reflects how the row was inserted. This query will be stored to a table in another database.
To illustrate:
Database A has table products (id, name, duration, isavailable).
Database B has a table mysql_query (id, query)
When a new row (1001, 'test product', 365, 1) is inserted into A.products, the trigger should insert the following into B.mysql_query:
INSERT INTO products (id, name, duration, value, isavailable)
VALUES (1001, test product, 365, 1, 1)
Value by default will always be 1 for the moment.
The code for the trigger so far is:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER c_products
ON migrimi_test.dbo.products
AFTER INSERT
AS
DECLARE #c_id INT;
SET #c_id = (SELECT id from inserted);
DECLARE #c_name INT;
SET #c_name = (SELECT name from inserted);
DECLARE #c_duration INT;
SET #c_duration = (SELECT duration from inserted);
DECLARE #c_isavailable INT;
SET #c_isavailable = (SELECT isvisible from inserted);
BEGIN
SET NOCOUNT ON
INSERT INTO migrimi_temp.dbo.mysql_query (id, mysql_query)
VALUES (DEFAULT, 'INSERT INTO products (id, name, duration, value, isavailable) values ('+CAST(#c_id as nvarchar(50))+', '+'"'+#c_name'+'"'+, '+#c_duration+', 1, '+#c_isavailable+')' )
END
GO
I run the trigger and latter perform an insert. There is an error saying:
Conversion failed when converting the nvarchar value 'test product' to data type int.
I understand that it refers to the substitution of variable #c_name but this is the first trigger I ever write, and I can't tell what exactly is wrong.
A and B are SQL databases.

Answer 1

Ok, there were 3 problems with the trigger:
1- As WEI_DBA pointed out, #c_name was declared int, even though it was in fact an varchar.
2- Apparently every int variable should be cast as a varchar or it will throw the following error:
sql trigger Conversion failed when converting the varchar value to
datatype int
I still don't have this figured out 100% - this is the solution but I am googling the reason why. So don't take my word for granted and feel free to provide more reliable sources or alternative explanations / solutions. After all I am a trigger newbie.
3- While the trigger itself will work, the query inserted in the table mysql_query will be invalid unless the value #c_name (or any varchar value) is surrounded by double quotes.
The final result of a working trigger is the following:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER c_products
ON migrimi_test.dbo.products
AFTER INSERT
AS
DECLARE #c_id INT;
DECLARE #c_name nvarchar(100);
DECLARE #c_duration int;
DECLARE #c_isavailable INT;
Select #c_id = id, #c_name = name, #c_duration = duration, #c_isavailable = isvisible from inserted
BEGIN
SET NOCOUNT ON
INSERT INTO migrimi_temp.dbo.sql_query (query)
VALUES ('INSERT INTO products (id, name, duration, value, isavailable, createdAt, updatedAt) values ('+CAST(#c_id as nvarchar(50))+', '+'"'+#c_name+'"'+',
'+CAST(#c_duration as nvarchar(50))+', 1, '+CAST(#c_isavailable as nvarchar(50))+', Now(), Now());' )
END
GO
Ignore the new fields, there were modifications that I made but have nothing to do with the issue at hand.
