Sql 接收变量的数据类型varchar不等于列的数据类型nvarchar

我收到了一条关于这个的错误消息。错误消息是：

接收变量的数据类型varchar不等于数据类型 “VEHICLE_ID2_FW”列的nvarchar

请帮忙，谢谢

DECLARE @IMPORTID INT
DECLARE @LASTID INT
DECLARE @VEHICLEID VARCHAR (20)

SELECT @LASTID = (SELECT LAST_REFERENCE_FW FROM REFERENCE_FW WHERE RECORD_TYPE_FW = 'VEHICLES_ORDERS_FW' AND REFERENCE_FIELD_FW = 'VEHICLE_ID2_FW' AND ARCHIVE_STATUS_FW ='N')
SELECT @IMPORTID = (SELECT IMPORT_ID_FW FROM VEHICLES_ORDERS_FW WHERE RECORD_NUMBER_FW = %RECORD_NUMBER_FW%)
SELECT @VEHICLEID = (SELECT VEHICLE_ID2_FW FROM VEHICLES_ORDERS_FW WHERE RECORD_NUMBER_FW = %RECORD_NUMBER_FW%)

IF @IMPORTID IS NOT NULL AND @VEHICLEID IS NULL

BEGIN
UPDATE VEHICLES_ORDERS_FW
SET @LASTID = VEHICLES_ORDERS_FW.VEHICLE_ID2_FW = @LASTID+1
FROM VEHICLES_ORDERS_FW
WHERE RECORD_NUMBER_FW = %RECORD_NUMBER_FW%;

UPDATE VEHICLES_ORDERS_FW
SET VEHICLES_ORDERS_FW.VEHICLE_ID2_FW = 'FW'+VEHICLE_ID2_FW
FROM VEHICLES_ORDERS_FW
WHERE RECORD_NUMBER_FW = %RECORD_NUMBER_FW%

END

Mabey问题是：

set @LASTID = VEHICLES_ORDERS_FW.VEHICLE_ID2_FW = @LASTID + 1

---

如果您提供表结构，这将很好。

Mabey问题在于：

set @LASTID = VEHICLES_ORDERS_FW.VEHICLE_ID2_FW = @LASTID + 1

如果您不想更改表数据类型。如果不想更改表数据类型，可以使用

cast

或

CONVERT

键入cast列。您可以使用

cast

或

CONVERT

尝试使用下面的脚本更改脚本

DECLARE @IMPORTID INT
DECLARE @LASTID INT
DECLARE @VEHICLEID VARCHAR (20)

SELECT @LASTID = (SELECT LAST_REFERENCE_FW FROM REFERENCE_FW WHERE RECORD_TYPE_FW like N'VEHICLES_ORDERS_FW' AND REFERENCE_FIELD_FW LIKE N'VEHICLE_ID2_FW' AND ARCHIVE_STATUS_FW  LIKE N'N')

SELECT @IMPORTID = (SELECT IMPORT_ID_FW FROM VEHICLES_ORDERS_FW WHERE CAST(RECORD_NUMBER_FW  AS NVARCHAR) LIKE CONCAT(N'%', CAST(RECORD_NUMBER_FW AS NVARCHAR),N'%'))

SELECT @VEHICLEID = (SELECT VEHICLE_ID2_FW FROM VEHICLES_ORDERS_FW WHERE CAST(RECORD_NUMBER_FW  AS NVARCHAR)  = CONCAT(N'%', CAST(RECORD_NUMBER_FW AS NVARCHAR),N'%'))

IF @IMPORTID IS NOT NULL AND @VEHICLEID IS NULL

BEGIN
UPDATE VEHICLES_ORDERS_FW
SET @LASTID = @LASTID+1
FROM VEHICLES_ORDERS_FW
WHERE CAST(RECORD_NUMBER_FW  AS NVARCHAR) LIKE CONCAT(N'%', CAST(RECORD_NUMBER_FW AS NVARCHAR),N'%');

UPDATE VEHICLES_ORDERS_FW
SET VEHICLES_ORDERS_FW.VEHICLE_ID2_FW = CONCAT(N'FW',VEHICLE_ID2_FW)
FROM VEHICLES_ORDERS_FW
WHERE CAST(RECORD_NUMBER_FW  AS NVARCHAR) LIKE CONCAT(N'%', CAST(RECORD_NUMBER_FW AS NVARCHAR),N'%');

仍然有错误消息“接收变量的ata类型int不等于‘VEHICLE_ID2_FW’列的数据类型nvarchar”。“VEHICLE_ID2_FW=VARCHAR（20）LAST_REFERENCE_FW=integers直到有错误消息“接收变量的ata类型int不等于‘VEHICLE_ID2_FW’列的数据类型nvarchar”。“VEHICLE_ID2_FW=VARCHAR（20）LAST_REFERENCE_FW=integerThank它确实有效，我刚刚删除了concat记录编号，因为它是系统中仅发生在该特定记录上的固定编号。@user3585538+1，供您根据需要修改解决方案！感谢它确实有效，我刚刚删除了concat记录编号，因为它是系统中仅在该特定记录上发生的固定编号。@user3585538+1，供您根据需要修改解决方案！如果你需要做CAST／转换，花几秒钟考虑你的DB设计。（通常表示坏的设计）如果你需要做CAST /转换，花几秒钟考虑你的DB设计。（通常表示设计不好。）
