这是我的密码：

CREATE TABLE IF NOT EXISTS Artfacture 
(
     N int(6) unsigned NOT NULL,
     Code varchar(50) NOT NULL,
     Ht Numeric NOT NULL 
)
INSERT INTO Artfacture (N, Code, Ht) 
VALUES ('1', '1', '10'), ('1', '2', '20'),('1', '3', '30');
CREATE TABLE IF NOT EXISTS Facture 
(
     N int(6) unsigned NOT NULL,
     Ht Numeric NOT NULL 
)
INSERT INTO Facture (N, Ht) 
VALUES ('1', '60');
CREATE TABLE IF NOT EXISTS Article 
(
     Code varchar(50) NOT NULL, 
     Famille varchar(50) NOT NULL 
)
INSERT INTO Article (Code, Famille) 
VALUES ('1', 'F1'), ('2', 'F2'), ('3', 'F3');
CREATE TABLE IF NOT EXISTS Farticle 
(
     Designation varchar(50) NOT NULL, 
     Compte varchar(50) NOT NULL 
)
INSERT INTO Farticle (Designation, Compte)  
VALUES ('F1', '700000'), ('F2', '710000'), ('F3', '720000');
CREATE TABLE IF NOT EXISTS Ecritures 
(
     Compte varchar(50) NOT NULL, 
     Ht numeric NOT NULL  
)

我的请求是一个触发器，在表facture中添加一些新行时，它必须在ecritures中添加与artfacture行数相同的行

declare @piece as nvarchar(50), @code as nvarchar(50)
declare @rowCount int = 0, @currentRow int = 1
select @rowCount = count(*) from ArtFacture where N = @piece;
while (@currentRow <= @rowCount)
begin
    set @Code = (select code from ArtFacture where N = @piece)
    set @compte = (select Compte from Farticle where Designation = (select Famille from Article where code = @code))
    set @Ht = (select ht from ArtFacture where N = @piece)
    insert into Ecritures (Compte,Ht)
    values (@compte,@Ht)
end

我有一个错误，但我不知道在哪里？
