  This error usually arises due to the following reasons:
  
  Table Locking: The table you are trying to alter is currently locked by another transaction or user.

  Check Constraints: Review the database constraints associated with the table. Ensure that your operation does not violate any foreign key or other constraints.
  
  
  Use Appropriate Transactions: If you are trying to alter a table that is part of a view or a join, consider using the appropriate transaction or method to update the data instead of directly altering the table.
