我正在开发用于库存管理的桌面应用程序。无法使用存储过程从SQL Server表中删除记录
我在SQL Server中3个表：
- 交易
- MATERIAL_TRANSACTION
- TRANSACTION_DETAILS
我创建了一个存储过程来插入以及更新上述所有表。
TRANSACTIONS是我的主表。所以，我使用更新查询来更新其列。 但是在将新行插入数据库之前，需要删除其他两个表（即详细表）的记录。
我无法删除此存储过程中的行。请帮忙！
我用下面的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,

DECLARE @TRAN_ID INT
BEGIN
SET NOCOUNT ON;

WHERE ID > 0

SET @TRAN_ID = @@IDENTITY
END
ELSE
BEGIN

END
--UPDATE MATERIAL_TRANSACTION SET IS_DELETED=1 WHERE [email protected];

INSERT INTO TRANSACTION_DETAILS (TRANSACTION_ID, AC_ID, TRAN_TYPE,
CR_AMT, DR_AMT, AMT_PERCENT, IS_PARENT)
SELECT
@TRAN_ID, [AC_ID], [TRAN_TYPE],
[CR_AMT], [DR_AMT], [AMT_PERCENT], [IS_PARENT]
FROM
@TRANSACTION_DETAILS TVP
INSERT INTO MATERIAL_TRANSACTION (TRANSACTION_ID, PRODUCT_ID, QTY,
UNIT_ID, DESCRIPTION, HSN_CODE,
PRICE, DISCOUNT_AMT, DISCOUNT_PERCENT,
CGST_PERCENT, SGST_PERCENT, IGST_PERCENT,
CGST_AMT, SGST_AMT, IGST_AMT)
SELECT

SELECT @RETURN = @TRAN_ID
END
@ID参数被声明为nvarchar（50），但代码中的文字是整数。该参数应该与基础表中的“TRANSACTION_ID”的数据类型相匹配。 –
未来版本的SQL Server中将删除'ntext'，'text'和'image'数据类型。避免在新的开发工作中使用这些数据类型，并计划修改当前正在使用它们的应用程序。改为使用'nvarchar（max）'，'varchar（max）'和'varbinary（max）'。 [请参阅此处]（http://msdn.microsoft.com/en-us/library/ms187993.aspx） –
