Column definition mapping 'uniqueidentifier '

I think @GeneratedValue must be an INTEGER. Having GUID as auto generated value is logically incorrect. DB won't be able to generate next value on it's own.

I have just created a stored procedure actually; I am about to test it. Thank you!

This can be over-engineering but did you consider creating a Stored Procedure that does it for you? You just pass your inputs to it and leave the rest to it?

I couldn't try this solution because the function "executequery" doesn't exist. Is there an alternative to resolve this error?

Hello Ajinkya, Below is the code snippet, I was able to insert value from Appian to Unique Identifier of MS SQL:

executequery(cons!DATABASE, "INSERT INTO Employoee (
AttachmentId,
RequestId,
CustomerId,
)
VALUES (
NEWID(),
CONVERT(uniqueidentifier,'"&ri!RequestId&"'),
CONVERT(uniqueidentifier,'"&ri!CustomerId&"')
)")
Where both rule inputs are of type text, passed from a process model to this rule.

Ajinkya, If the column is autogenerated, then i believe we cannot insert in that column. But if the column is not auto generated, then i believe we can insert data, i have done it before using executesql function. Let me check if i have that code snippet,,,,, I will share it with you shortly.

@Ajinkya Bendre, as per my Understanding You can define String Data Type as uniqueIdentifier as i already have used it earlier, as shown below:-
===========================================================================

@Id
@Column(name="EmployeeID",columnDefinition="VARCHAR(255)")

===========================================================================

But in this case we cannot treat this column to be Auto Generated (i.e. @GeneratedValue), as Integer Type, in Such Cases you need to provide Unique values for that column such as Email ID, Organization Employee ID etc....

Hope this will Help You

@Ajinkya Bendre....AFAIK We cannot make string datatype as uniqueidentifier...

As for the above error i could understand that you are using a string datatype as a unique identifier..

Hi Vinit ,
I am trying to insert data in Session table. In Session table, we have many columns out of which GuId is one of the column with the data type uniqueidentifier . This column gets auto-populated from a database.
I am able to verify mapping successfully with above changes that you suggested . But when I try to write session data in database 'Wtite to data store' smart service throws below error.

could not load an entity: [DsReportSessionDT37737#]:
com.microsoft.sqlserver.jdbc.SQLServerException: Conversion failed when
converting from a character string to uniqueidentifier.

Hello Ajinkya, If you are fetching the data from SQL Server DB, then can use string as shown in below format: <xsd:element name="ProjectId" nillable="true" type="xsd:string">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">
@Column(name = "ProjectId" columnDefinition="uniqueidentifier")
</xsd:appinfo>
</xsd:annotation>
</xsd:element>

Regards,
Vinit.
