Thank you Stefan. It is working now.

Thank you. When I removed the initial sort from the record list, the sorting of field with record link worked properly and did not give any issue.

I have the same idea. Please check that.

@Brinda,

Can you share the initial sort configuration you have for the Grid in Record Types and also sort configuration of the grid column "Student Full Name"?

It seems like you might have used rf!STUDENT_FULL_NM or something similar to that instead of just "STUDENT_FULL_NM "

Hm ... sorry, I am out of ideas ...

Hi Stefan,

Thanks for your reply.

I am using this "STUDENT_FULL_NM" in the view as a link field. The following is the configuration for the link field:

a!recordLink(
label: rf!STUDENT_FULL_NM,
recordType:rp!type,
identifier:rp!id
)

It gives the alias error which I mentioned only in the link field, when I use it in the normal text field in the record list it is sorting properly and does not give any error.

The Appian version I am using is 21.1. Any suggestion?

I meant the record list configuration.

I don't think so. The following is a part of XSD definition for TEST_VW_Student CDT:

<xsd:element name="STUDENT_FULL_NM" nillable="true" type="xsd:string">
<xsd:annotation>
<xsd:appinfo source="appian.jpa">@Column(name="STUDENT_FULL_NM", columnDefinition="VARCHAR(255)")</xsd:appinfo>
</xsd:annotation>
</xsd:element>

But the view in cloud database does not have the primary key. By any chance, is the error due to that?

I have created the recordtype from the view as the data source. The record list field is giving error while sorting

Seems to be OK. By any chance, the piece

"alias [[field=STUDENT_FULL_NM, ascending=true]]" in the error message does not match.

Could it be that you entered that in a wrong field or typed it as a string (in quotes) instead of code?

Where exactly are you implementing your sort on this field? Is it in an Interface object? If so, please provide the code for that Interface.

I have created a view from the student table to get student full name. I am using this view as a datasource for my entity-backed record where the "STUDENT_FULL_NM" sorting is giving the error. The SQL coding for view is as follows:

CREATE OR REPLACE VIEW `TEST_VW_Student` AS
SELECT
`Student`.`STUDENT_ID` AS `STUDENT_ID`,
`Student`.`STUDENT_F_NM` AS `STUDENT_F_NM`,
`Student`.`STUDENT_M_NM` AS `STUDENT_M_NM`,
`Student`.`STUDENT_L_NM` AS `STUDENT_L_NM`,
CAST(
CONCAT(
CASE WHEN `Student`.`STUDENT_L_NM` = ' ' OR `Student`.`STUDENT_L_NM` IS NULL THEN 'Last Name' ELSE `Student`.`STUDENT_L_NM`
END,
', ',
`Student`.`STUDENT_F_NM`,
' ',
CASE WHEN `Student`.`STUDENT_M_NM` = ' ' OR `Student`.`STUDENT_M_NM` IS NULL THEN '' ELSE `Student`.`STUDENT_M_NM`
END
) AS CHAR(100) CHARSET utf8mb4
) AS `STUDENT_FULL_NM`

OK. What is your queryEntity code?

RE: Error in Record sorting

Brinda — Fri, 23 Jul 2021 10:17:47 GMT

But my field name in the view and CDT is STUDENT_FULL_NM Stefan

I think the issue is that the alias for the concat is "Student Full Name". Appian does not support field names containing spaces. Changing this to e.g. "Student_Full_Name" should do it.
