Question

Sort order of column on EntitySchemaQuery

Hi Community,

 

I've written some code that extracts data from an object using an EntitySchemaQuery.

Everything is working fine with data extraction.

When I try to order the EntitySchemaQuery using a code similar to the one on this article:

https://community.bpmonline.com/questions/how-sort-esq

column.orderDirection = Terrasoft.OrderDirection.DESC;

I get the following compilation errors:

What am I missing?

 

Thanks in advance,

Luis

Dear Luis,

The article that was mentioned above is related to client esq. The issue happens because you try to use the client esq code inside the server esq code.

 
Please find an example about how to sort in both server and client esq in the article by the link below:

https://community.bpmonline.com/articles/how-sort-records-date-modifica…

Additionally, please find more information in the article by the link below:

https://academy.bpmonline.com/api/netcoreapi/7.13.0/index.html#Terrasof…

Best regards,
Norton

Norton Lingard,

 

Hi Norton,

thanks a lot, it was a stupid mistake. I tried OrderByAsc and it is working to sort one column.

I realized I do need help with one other point:

the output of the sorted table should sort by 2 columns, 1st by "License Plate" and then by "status service date".

Is there a way to apply an equivalent to the ThenBy class from c#?

something like "StatusServiceQuery.OrderBy(c => c.LastName).ThenBy(c => c.FirstName)

like described here: https://stackoverflow.com/questions/2779375/order-a-list-c-by-many-fiel…

Thanks in advance,

Luis

 

 

Hi Norton/Tyler,

 

I ran some tests and if I apply the sort OrderByAsc 2 times for the diferent columns it has the ThenBy behaviour, so please forget my last comment and thaks for all the help!

Luis

col1.OrderByAsc(0);
col2.OrderByAsc(0);
