How to resolve the issue of invalid column names when creating a view in SQL?

To solve the issue of creating a view in SQL with an invalid column name, consider the following aspects:

1. Check if the column names exist: Make sure that the column names referenced in the view exist in the database. If a column name does not exist or is written incorrectly, it will result in an error stating that the column name is invalid.
2. Check the naming rules for columns: Make sure the column names adhere to the database naming conventions, such as not containing special characters or keywords, and not exceeding the database length limit.
3. Check the alias of column names: make sure that aliases used when creating a view are correctly referenced within the view.
4. Check permissions for tables or views: If there is not enough permission to access a table or view, it may result in an error stating the column name is invalid. Make sure the current user has enough permission to access the relevant objects.
5. Check SQL syntax: Ensure that the SQL syntax for creating the view is correct, without any syntax errors or missing necessary keywords.

If all the above steps have been checked and the problem still cannot be resolved, you can try creating a simple view in the database, which only includes one table and references only one column, to see if the view can be successfully created. If the view can be successfully created, then it may be the names of other columns or the logic within the view that are causing the issue. If even a simple view cannot be created, it may be a problem with the database or the tool itself, and you can try upgrading the database or using a different tool.
