how do a merge of sql server with mule? - mule

Question

I have done this with a foreach and execute dll operation, but when try insert o uptdate a string throw a exeption, however with a int values works.
The exeption:`Exception stack is:
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)

Answer 1

When working with dynamic query there is no parameter conversion, for this reason you need to add quotes to string arguments, so in your case it should look something like that:
<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>
Just one note on security: Pay attention when using dynamic query, you are vulnerable to SQL Injection in this way, so make sure you sanitize this parameters before passing it to the DLL.
