  "account": "Renaming a column in SQL Server can cause unexpected problems. The example given was a misspelled column called Ammount. The SQL command to rename the column is EXEC sp_rename dbo.Invoice.Ammount, Amount, COLUMN;. While the rename operation itself works fine, it can break scripts and stored procedures that reference the old column name. These issues are not immediately apparent, and can cause failures when the renamed column is used later on.\n\nFor example, a view called InvoiceTotal that selects from the Invoice table will fail with an error stating that the column \"Ammount\" is invalid. Similarly, a stored procedure called GetInvoice will also fail with the same error. This means that after renaming a column, all objects that reference that column must be updated before they can be used again. If not, they will continue to produce errors, causing issues for anyone who uses those objects.\n\nTo avoid these problems, it is important to carefully review all objects that use the renamed column before making the change. This can be done by querying the sys.dm_sql_referencing_entities system view to see which objects reference the column, and then searching their definitions for the old column name. By doing this, any necessary updates can be made before the rename is performed, and the operation can be completed without any unexpected issues.",

The rename itself is one line: EXEC sp_rename 'dbo.Invoice.Ammount' , 'Amount' , 'COLUMN' ; Caution: Changing any part of an object name could break scripts and stored procedures. That caution is the entire problem, stated once and never mentioned again. The rename succeeds. What breaks, breaks later, and in a…",
