Question

我正在开发一个用于库存管理的桌面应用程序。

我在SQL Server中有3个表：

TRANSACTIONS
MATERIAL_TRANSACTION
TRANSACTION_DETAILS

我已经创建了一个存储过程来插入和更新所有上面提到的表。

TRANSACTIONS是我的主表。因此，我使用更新查询来更新其列。但是在数据库中插入新行之前，需要删除其他两个表的记录，即详细表。

我无法删除此存储过程中的行。请帮忙！

我使用了以下SQL Server存储过程

ALTER PROCEDURE [dbo].[SAVE_TRANSACTION] 
    @ID NVARCHAR(50),
    @REF_NO NVARCHAR(50),
    @VCH_DATE DATE,
    @VCH_TYPE INT,
    @CR_AC INT,
    @DR_AC INT,
    @DOCKET_NO NVARCHAR(50),
    @TRANSPORT NVARCHAR(50),
    @DELIVERY_NOTE NTEXT,
    @S_NAR NVARCHAR(100),
    @L_NAR NTEXT,
    @IS_REVERSE_CHARGE INT,
    @INVOICE_REF INT,
    @BUYER NVARCHAR(50),
    @BUYER_CONTACT NVARCHAR(50),

    @TRANSACTION_DETAILS dbo.TVP_TRANSACTION_DETAILS READONLY,
    @RETURN INT OUTPUT

    DECLARE @TRAN_ID INT
BEGIN
    SET NOCOUNT ON; 

    DELETE FROM MATERIAL_TRANSACTION 
    WHERE ID > 0 
      AND TRANSACTION_ID = @ID;

    DELETE FROM TRANSACTION_DETAILS 
    WHERE ID > 0 
      AND TRANSACTION_ID = @ID;

    IF (@ID = 0)
    BEGIN
        INSERT INTO dbo.TRANSACTIONS(REF_NO, VCH_DATE, VCH_TYPE, CR_AC, DR_AC,
