如何将sql server与mule合并？

我使用foreach并执行dll操作，但是当尝试插入o uptdate时，一个字符串抛出一个exeption，但是int值有效。

该例外：`异常堆栈是：

1. Invalid column name 'Carlos'. (com.microsoft.sqlserver.jdbc.SQLServerException)
  com.microsoft.sqlserver.jdbc.SQLServerException:217 (null)
2. Invalid column name 'Carlos'. (com.microsoft.sqlserver.jdbc.SQLServerException). Message payload is of type: LinkedHashMap (org.mule.api.MessagingException)
  org.mule.module.db.internal.processor.AbstractDbMessageProcessor:93 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/MessagingException.html)

'Carlos'是有效载荷的值。

这是DLL 

BEGIN MERGE [FP].[Profile] AS DESTINO USING (SELECT #[payload.ID]) AS
FUENTE (ID) ON (DESTINO.ID=FUENTE.ID) WHEN MATCHED THEN UPDATE SET 
[UserId]= #[payload.UserId] WHEN NOT MATCHED THEN INSERT 
(ID,UserId,ExternalId,FirstName) VALUES (#[payload.ID],#
[payload.UserId],#[payload.ExternalId],#[payload.FirstName]); END

使用动态查询时，没有参数转换，因此您需要在字符串参数中添加引号，因此在您的情况下它应该看起来像这样：

<db:dynamic-query><![CDATA[BEGIN MERGE [FP].[Profile] AS DESTINO
USING (SELECT #[payload.ID]) AS FUENTE (ID)
ON (DESTINO.ID=FUENTE.ID)
WHEN MATCHED THEN
    UPDATE SET 
        [UserId]= '#[payload.UserId]',
        [FirstName]=#[payload.FirstName]
WHEN NOT MATCHED THEN
    INSERT 
        (ID,UserId,ExternalId,[FirstName])
    VALUES
       (#[payload.ID],'#[payload.UserId]',#[payload.ExternalId],'#[payload.FirstName]'); END]]></db:dynamic-query>

关于安全性的一点注意事项：在使用动态查询时要注意，以这种方式容易受到SQL注入攻击，因此请确保在将此参数传递给DLL之前对其进行清理。
