It would help if you could provide additional context.
What database(s) inputs are you using?Are you attempting to write the queries directly in the SQL Editor or copy/paste from another IDE (e.g. SQL Management Studio)?
What types of joins are you using?
Can you provide screenshots?
I am using SQL database. I am trying to write the queries in SQL editor by copy pasting it from another IDE (Toad)
I am using inner joins. I am not sure I can send screen shots.
Can we copy paste directly into the SQL Editor.
I use the SQL editor quite frequently and just copy and paste from Toad or SQL Server Management Studio. I have found that more complex queries tend to fail when requiring to input a parameter. For the most part no issues.
Copy/Paste from an IDE is allowed. Sometimes queries that include comments may not be parsed correctly and may throw an error. Depending on the query you may need to determine if an error is thrown if the issue is syntax, an unsupported method, or other.
One of the strengths of Alteryx is to visually layout through a workflow what a query does, and possibly more. I'm curious why you're using a pre-defined sql script vs using Alteryx natively
